I had one of the original Nintendo DS games. This new design is much more streamlined, however. Yeah, the new DSi is out, but heck, can it still play advance games? no. So DS lite is still it. Love it. Dell is great the Metallic Pink looks way better when its in your hand as opposed to online. Super easy to use and rechargable. Just overall fun "toy none

WIRING IT UP

Balanced Mic XLR

MIC INPUT

The mic input accepts XLR-type connectors and is designed to suit a wide range of BALANCED or UNBALANCED low-level signals, whether from delicate vocals requiring the best low-noise performance or close-miked drum kits needing maximum headroom. Professional dynamic, condenser or ribbon mics are best because these will be LOW IMPEDANCE. While you can use low-cost HIGH IMPEDANCE mics, you do not get the same degree of immunity to interference on the microphone cable and as a result the level of background noise may be higher. If you turn the PHANTOM POWER on (top right-hand side of the mixer) the socket provides a suitable powering voltage for professional condenser mics. DO NOT use unbalanced sources with the phantom power switched on. The voltage on pins 2 & 3 of the XLR connector may cause serious damage.

Signal Gnd/Screen Gnd/Screen
Accepts 3-pole `A gauge (TRS) jacks, or 2-pole mono jacks which will automatically ground the 'cold' input. Use this input for sources other than mics, such as keyboards, drum machines, synths, tape machines or guitars. The input is BALANCED for low noise and immunity from interference, but you can use UNBALANCED sources by wiring up the jacks as shown below, although you should then keep cable lengths as short as possible to minimise interference pick-up on the cable. Note that the ring must be grounded if the source is unbalanced. Unplug anything in the MIC input if you want to use this socket. Set the input level using the TRIM knob.

INSERT POINT

The unbalanced, pre-EQ insert point is a break in the channel signal path, allowing limiters, compressors, special EQ or other signal processing units to be added in the signal path. The Insert is a 3-pole 'A' gauge jack socket which is normally bypassed. When a jack is inserted, the signal path is broken, just before the EQ section. The signal from the channel appears on the TIP of the plug and is returned on the RING.

STEREO INPUTs

Accept 3-pole `A gauge (TRS) jacks, or 2-pole mono jacks which will automatically ground the 'cold' input. Use these inputs for sources such as keyboards, drum machines, synths, tape machines or as returns from processing units. The input is BALANCED for low noise and immunity from interference, but you can use UNBALANCED sources by wiring up the jacks as shown below, although you should then keep cable lengths as short as possible to minimise interference pick-up on the cable. Note that the ring must be grounded if the source is unbalanced. Mono sources can be fed to both paths by plugging into the Left jack only.

FX RETURNS

Similar to the Stereo Inputs, except that they are unbalanced. Input gain is sufficient to allow the connection of +4dBu professional or -10dBV semi-professional equipment.

Mix INSERTS

The unbalanced, pre-fade Mix insert point is a break in the output signal path to allow the connection of, for example, a compressor/limiter or graphic equaliser. The Insert is a 3-pole 'A' gauge jack socket which is normally bypassed. When a jack is inserted, the signal path is broken, just before the mix fader. The mix signal appears on the TIP of the plug and is returned on the RING. A 'Y' lead may be required to connect to equipment with separate send and return jacks as shown below:

Headphones Left Signal Right Signal Ground

HEADPHONES

The PHONES output is a 3-pole 'A' gauge jack, wired as a stereo output as shown, suitable for headphones of 200W or greater, although impedances as low as 50W will operate satisfactorily. 8W headphones are not recommended. Inserting a jack automatically cuts off the Monitor outputs (see above), which are restored when the PHONES jack is removed. This allows a self-operator to continue monitoring while making voice recordings without having to turn the power amplifiers down.

GROUNDING CONSIDERATIONS

The power supply does not provide the mixer with any direct connection to mains ground, and therefore some care must be taken to ensure that a ground connection is made at an appropriate point in the system. In PA systems the most suitable point would be to ground through the Mix Outputs into the power amp leads. In a studio setup the Monitor Outputs would provide a suitable connection via the monitor power amp leads.

INITIAL setting up

You will probably use your SPIRIT FOLIO LITE with a wide range of different types of sound source, and these will be at varying signal levels. The mic amp has been designed with a particularly wide gain range, but it is important to set the TRIM control correctly to give the best performance. If the input level is too high the signal will distort as it overloads the channel and causes clipping. If it is too low the level of any background hiss will be more noticeable and you may not be able to get enough signal level to the output of the mixer. This is illustrated in the diagram below. Set up the individual mono input channels as follows: o Plug in the chosen source (usually the MIC input for mics and the LINE input for anything else). Plug in phantom powered mics before switching the phantom power on. o Set the rotary Mix Fader on the Master section fully anticlockwise. Press the PFL switch on the Master section to route PFL to the monitor and meters. o Provide the chosen source with a typical signal level and press the PFL button by the fader. The level of signal will be shown on the Bargraph Meters. o Adjust the input TRIM until the meter is just reaching the amber LED (0dB) at a typical maximum source level with a steady signal. If the source signal is rich in high-level transients (e.g. drums) a rather higher meter reading of +6/+9 will be needed to achieve an equivalent average level. This leaves enough headroom to cope with peaks in the signal without distortion. o Adjust each mono input channel in the same way. o If you find that you cannot set a reasonable level within the range of the TRIM control when using a MIC input, try the LINE input instead. The Stereo inputs can be set up in a similar way. Start with the GAIN control anticlockwise, which will suit inputs from professional equipment with a +4dBu output. A higher GAIN setting will be needed for semiprofessional sources which typically have -10dBV output level. You will now have initial settings for each of the input sources and are ready to start building a mix. o Connect your power amplifiers and speakers and set the gain of the amplifiers to about 70%. Set the Master Fader fully clockwise, listening carefully for any hint of feedback or overload. You may find that the input fader settings will need to be edged back slightly as the mix is built up. o Listen carefully for the characteristic sound of `feedback. If you cannot achieve a satisfactory input level setting without feedback, adjust microphone and speaker positions and try again. Careful microphone placement and the choice of a suitable type of microphone is essential for successful PA use. The aim should be to place the microphone as close as possible to the source, to cut out unwanted surrounding sounds. This allows a lower gain setting on the mixer and helps to avoid feedback. You will also find that a well-placed microphone will not need any appreciable equalisation.

Clipped Signal

If the signal level is too high, clipping distortion may occur.

Signal

If the signal level is too low it may be masked by the noise.
The inherent low noise of the input channels on FOLIO LITE allows an alternative method of setting-up, which allows the use of the optimum range of the input faders. o Set the Master Fader fully clockwise. o Set all input faders to the '0' mark. Note that this still allows 10dB of gain in hand. o Gradually bring up each channel by adjusting the input TRIM control until the required mix is created.

SETTING UP FOR RECORDING

While the connections to the FOLIO LITE for PA work are quite straightforward, recording is rather more demanding because the mixer is not only required to mix down input signals but also to provide a monitor mix for artists to hear. The f following describes a typical set-up for recording two tracks on a multitrack recorder, but would be similar for a 2-Track machine: o Connect input sources and set gain as described opposite. Connect Mix Left & Right outputs to the multitrack tape inputs. o Route the channel signal to the required tape input by setting the PAN fully left or right. For example, panning fully left will route the signal from the Left Mix output only. This allows an individual source to be sent to an individual tape track. o Connect the multitrack tape outputs to the 2 Track Returns. Set the 2TRK LEVEL control fully clockwise for -10dBV sources, or at a lower setting for equipment with a higher output level. o Connect a monitor amplifier for foldback headphones or a monitor speaker to the Aux 1 output. Set the amplifier volume to a normal listening level. Press the AUX 1 PRE switch on the Master section to set all channel Aux 1 sends to pre-fade. o Use the Aux 1 send controls on the input channels to set up a mono monitor mix. (make sure that all other Aux 1 controls are fully off) o If a compressor is to be used, connect this to the Mix Insert points. o Connect any effects required using Aux 2, and return them to the mixer on unused Line or Stereo inputs or FX Return to allow the effect to be balanced with the original source. If it is necessary to hear the off-tape signal as part of the foldback mix, for instance for overdubbing, connect the tape outputs to unused stereo or line inputs, which can access the Aux 1 send.
It is important to match the input and output levels of your mixer and recording device to avoid distortion and create the best recording. o Set the recording level as recommended for your recording device, feeding a suitable signal from the Mix outputs. With MONITOR SOURCE selected to MIX the meters will display the signal being fed to the recorder. o Monitor the signal going to the recorder by selecting 2TRK on the MONITOR SOURCE switch. Gradually increase the 2TRK level while toggling the MONITOR SOURCE switch to alternate between the Mix output and 2TRK return until no change in level is audible or visible on the LED meters.

mono input

FOLIO LITE has 4 Mono input channels, each with balanced inputs for microphone and line level sources, and an Insert point to allow the signal to be taken out of the mixer, through an external piece of equipment and then back into the mixer to continue through to the final output. The Insert point comes before the EQ and allows limiters, compressors and other signal processing units to be added as required to particular channels.
This knob sets how much of the source signal is sent to the rest of the mixer. Adjust it carefully -too high and the signal will overload and distort, too low, and the level of any background hiss will be more noticeable and you may not be able to get enough signal level to the output of the mixer. The 'U' mark gives a nominal unity gain for the Line input.

EQUALISER

The Equaliser (EQ) gives fine control over the signal quality, particularly to improve the sound in live PA applications where the original signal is often far from ideal. The EQ knobs can have a dramatic effect on the sound, so use them sparingly and listen carefully to the result.

-25 U -10

Turn to the right to boost high (treble) frequencies by up to 15dB at 12kHz, adding crispness to cymbals, vocals and electronic instruments. Turn to the left to cut these frequencies, reducing hiss or distorted consonants which can occur with certain types of microphone. Set the knob in the centre-detented position when not required.

-40 -60dB -4 u

Turn to the right to boost low (bass) frequencies by up to 15dB at 60Hz, adding warmth to vocals or extra punch to synths, guitars and drums. Turn to the left to reduce hum, stage rumble or improve a mushy sound. Set the knob to the centre-detented position when not required.

AUX 1 7

AUX SEND 1

AUX 2 7

This control sets the amount of the channel signal feeding the Right and Left MIX outputs, allowing you to move the source smoothly across the stereo image. When the control is turned fully right or left the signal is sent only to that side of the mix.

This is used to set up a separate mix for FOLDBACK, EFFECTS or recording, and the combination of all the Aux 1 Sends is mixed to the Aux 1 Output. For Effects it is useful for this to fade up and down with the FADER (this is called POSTFADE), but for Foldback or Monitor feeds it is important for the send to be independent of the FADER (this is called PRE-FADE). The Master Section AUX1 PRE switch allows you to chose pre- or post-fade as required. Leave the knob turned down when not in use.

AUX SEND 2

This is similar to the Aux Send 1 control, but is always POSTFADE.
The rotary FADER gives you smooth control of the overall signal level in the channel strip, allowing precise balancing of the various source signals being mixed to the Master Section.
When the PFL (Pre-Fade-Listen) switch is pressed the pre-fade signal is fed to both sides of the Monitor. It may be heard on headphones or the monitor output and shown on the meters if the Master section PFL switch is pressed. You use this switch to listen to a channel signal without affecting the mixer outputs, to check the signal quality, set the input TRIM, or simply to check that it is there!

stereo input

FOLIO LITE has 4 Stereo input channels, suitable for a wide variety of line level sources, such as keyboards, drum machines, synths or tape machines. The inputs are balanced for low noise and immunity from interference, but you can use unbalanced sources (see 'Connections' for wiring details), although you should then keep cable lengths as short as possible to minimise interference pick-up.
This knob allows you to match the input level to suit a wide variety of profesional, semi-professional and hi-fi sources. Start with a low setting, especially for professional equipment, and increase it if you cannot reach an adequate signal levelwith the fader at maximum.
The Equaliser (EQ) gives fine control over the signal quality, to minimise background noise, or to alter the character of synthesised voices from electronic instruments. The EQ knobs can have a dramatic effect on the sound, so use them sparingly and listen carefully to the result.

15 20dB 0 - 0+ 6 9

Turn to the right to boost high (treble) frequencies by up to 15dB at 12kHz, adding crispness to percussion from drum machines, synths and electronic instruments. Turn to the left to cut these frequencies, reducing hiss or excessive brillinace. Set the knob in the centredetented position when not required.

Turn to the right to boost low (bass) frequencies by up to 15dB at 60Hz, adding extra punch to synths, guitars and drums. Turn to the left to reduce hum, boominess or improve a mushy sound. Set the knob to the centre-detented position when not required.

BALANCE

This control sets the amount of the channel signal feeding the Right and Left MIX outputs, allowing you to balance the source in the stereo image. When the control is turned fully right or left you feed only that side of the signal to the mix.
This is used to set up a separate mono mix for FOLDBACK or to drive EFFECTS processors, and the combination of all the Aux 1 Sends is mixed to the Aux 1 Output. For Effects it is useful for this to fade up and down with the FADER (this is called POST-FADE), but for Foldback or Monitor feeds it is important for the send to be independent of the FADER (this is called PRE-FADE). The Master Section AUX1 PRE switch allows you to chose pre- or post-fade as required. Leave the knob turned down when not in use.
When the PFL (Pre-Fade-Listen) switch is pressed the pre-fade channel signal is fed in stereo to the Monitor. It may be heard on headphones or the monitor output and shown on the meters if the Master section PFL switch is pressed. You use this switch to listen to a channel signal without affecting the mixer outputs, to check the signal quality, set the input TRIM, or simply to check that it is there!

master section

FX RETURN
The unbalanced FX Returns are an ideal place to connect the output of an EFFECTS unit, without using up any of the LINE inputs. The control sets the level of signal fed directly to the MIX. When set fully clockwise the inputs will be matched to -10dBV (semi-professional) sources, or will suit +4dBu sources with the control at a lower setting. A mono source, plugged into the LEFT jack only is fed to both sides of the MIX.

2TRK (2 TRACK)

The unbalanced 2TK returns are an ideal place to connect the playback of a tape machine, without using up any of the LINE inputs. The control sets the level of signal fed directly to the MIX. When set fully clockwise the inputs will be matched to -10dBV (semiprofessional) sources, or will suit +4dBu sources with the control at a lower setting. A mono source, plugged into the LEFT jack only is fed to both sides of the MIX.
This switch turns on the 48V PHANTOM POWER to the mic inputs, sending a powering voltage down the same wires as the signal to suit many professional condenser mics. DO NOT turn on the phantom power when using unbalanced mics which may be damaged by the voltage. Note: Mics should always be plugged in before switching the Phantom Power ON.

2TRK TO MIX

Press this switch to route the 2TK Return signal to the MIX outputs giving you two extra inputs at mixdown. Adjust the level with the 2TRK control. Overall level will be set by the MIX FADER.

BARGRAPH METERS

The three-colour, peak-reading BARGRAPH METERS show the level of the selected monitor source (MIX, 2TRK or PFL) to give a warning of excessive peaks in the signal which might cause overloading. With the Master Fader at 0dB, aim to keep the signal just touching the amber segments, with a steady signal, or up to +6/+9 on peaky signal sources such as drum beats.

MIX FADER

The MIX FADER sets the final level of the MIX outputs. The fader should normally be set close to the '0dB' mark if the input levels have been set correctly.
This control sets the output level to the MONITOR LEFT & RIGHT outputs. If HEADPHONES are plugged into the PHONES jack the monitor outputs are cut off, and the knob then sets the headphone level.
Pressing this switch replaces the selected monitor source with the stereo PFL signal (mono from mono input channels). Releasing the switch returns the monitor to the previously selected source.

INITIAL SETTING UP

You will probably use your SPIRIT FOLIO RAC PAC with a wide range of different types of sound source, and these will be at varying signal levels. It is important to set the GAIN of the inputs correctly to give the best performance. Set up the individual Mono input channels as follows: Plug in the chosen source (usually the MIC input for mics and the LINE input for anything else). Plug in phantom powered mics before switching the phantom power on. Set the channel fader fully down. Set the Group and Master Faders at 0 and GROUPS TO MIX pressed. Select MIX to C/Room & Phones. Check that SOLO MODE is released. Release the channel routing switches to route to Groups 1-2 Provide the chosen source with a typical signal level and press the latching PFL button by the fader. The level of signal will be shown on the right-hand Bargraph Meter (the Left meter will be switched off when the PFL button is down). Adjust the input GAIN until the meter is just reaching the amber LED (0dB) at a typical maximum source level with a steady signal. If the source signal is rich in high-level transients (e.g. drums) a rather higher meter reading of +6/+9 will be needed to achieve an equivalent average level. This leaves enough headroom to cope with peaks in the signal without distortion. Adjust each input channel in the same way. If you find that you cannot set a reasonable level within the range of the GAIN control when using a MIC input on the Mono channels, try the LINE input instead. Stereo inputs 11-14 do not have a GAIN control, since the typical source for these inputs will be external tape machines or effects units which have a much more predictable signal level. Set the +4/-10 switch to +4 (released) initially, and check the input level with the PFL switch as decribed above. If the level is too low, switch to the -10 input setting. You will now have initial settings for each of the input sources and are ready to start building a mix. Connect your power amplifiers and speakers and set the gain of the amplifiers to about 70%. Move the individual channel faders gradually to the required working level, listening carefully for any hint of feedback or overload. You may find that the input gain settings will need to be edged back slightly as the mix is built up. Listen carefully for the characteristic sound of feedback. If you cannot achieve a satisfactory input level setting without feedback, adjust microphone and speaker positions and try again. Careful microphone placement and the choice of a suitable type of microphone is important for vocals. The aim should be to place the microphone as close as possible to the source, to cut out unwanted surrounding sounds. This allows a lower gain setting on the mixer and helps to avoid feedback. You will also find that a well-placed microphone will not need any appreciable equalisation.

SETTING UP FOR RECORDING

While the connections to the FOLIO RAC PAC for PA work are quite straightforward, recording is rather more demanding because the mixer is not only required to mix down input signals but also to provide a monitor mix for artists to hear previously recorded tracks when overdubbing new parts. Two typical set-ups are as follows:

Stereo Recording to DAT

Connect input sources and set gain as described above. Route the channels via the groups to Mix. Connect the Mix L/R outputs to the tape inputs. Connect the tape outputs to the 2TK Returns. Set the level control on these returns at zero. Connect a monitor amplifier for foldback headphones or a monitor speaker to the Aux 1 output. Set the amplifier volume to a normal listening level. Use the Aux 1 send controls on the tape channels to set up a mono monitor mix. (make sure that all other Aux 1 controls are fully off) If a compressor is to be used on an individual source, connect this to the channel insert point. Connect any effects required using Aux 2-6, and return them to the mix on the FX Returns or unused Stereo Returns to allow the effect to be balanced with the original source. It is important to match the input and output levels of your mixer and recording device to avoid distortion and create the best recording. Set the recording level as recommended for your recording device, feeding a suitable signal from the Group or Mix outputs. Monitor the signal going to the recorder by selecting the appropriate source on the C/Room & Phones source select switches. Gradually increase the 2TK return level control while alternately switching between the monitor source and 2TK until no change in level is detected.

8 Track Recording

Connect input sources and set gain as described above. Set the C/Room & Phones source to MIX. Check that the GROUPS TO MIX button is released. Connect the direct outputs on the eight required channels to the recorder inputs. Connect a monitor amplifier for foldback headphones or a monitor speaker to the Aux 1 or Aux 2 (set PRE) output. Set the amplifier volume to a normal listening level. If a compressor or other effect is to be used on an individual source, connect this to the channel insert point. Connect the recorder outputs to the 4 stereo returns. Route the returns to MIX. Alternatively, if only one or two tracks are being recorded, the machine outputs could be brought back to spare mono inputs and routed to a group for monitoring. The C/Room & Phones will now be listening to the monitor mix, or, if selected to Groups will carry the source mix. Note that the balance of these mixes will be essentially the same. This configuration allows a very high quality recording to be made, with the signal passing through the shortest signal path. The mixer may be reconfigured for a separate mix-down session to a stereo master at a later date.

THE CONTROLS IN DETAIL

MONO INPUT CHANNELS 1-TRIM
The TRIM control sets how much of the source signal is sent to the rest of the mixer. Too high, and the signal will distort as it overloads the channel and causes clipping. Too low, and the level of any background hiss will be more noticeable and you may not be able to get enough signal level to the output of Clipped the mixer. This is shown in the diagram on the Signal right: Setting the knob to the "+4U" mark gives unity gain on the LINE input for nominal +4dBu sources, which will be suitable for most professional equipment. Note that some sound equipment, particularly that intended for semi-professional use, operates at a lower level (-10dBV) and will therefore need a higher gain setting to give the same output level. A second point marked "-10U" indicates the unity gain setting for -10dBV sources. See "Initial Setting Up" to learn how to set the GAIN correctly.
If the signal level is too high, clipping distortion may occur.

Signal

If the signal level is too low it may be masked by the noise.

MIC INPUT

The mic input accepts XLR-type connectors and is designed to suit a wide range of BALANCED or UNBALANCED low-level signals, whether from delicate vocals requiring the best low-noise performance or close-miked drum kits needing maximum headroom. Professional dynamic, condenser or ribbon mics are best because these will be LOW IMPEDANCE. While you can use low-cost HIGH IMPEDANCE mics, you do not get the same degree of immunity to interference on the microphone cable and as a result the level of background noise may be higher. If you turn the PHANTOM POWER on (top right-hand side of the mixer) the socket provides a suitable powering voltage for professional condenser mics. DO NOT use unbalanced sources with the phantom power switched on. The voltage on pins 2 & 3 of the XLR connector may cause serious damage. Unplug any mics if you want to use the corresponding LINE Input to avoid the load presented by the mic from affecting the Line Input gain.

LINE INPUT

Accepts 3-pole A gauge (TRS) jacks. Use this input for sources other than mics, such as keyboards, drum machines, synths, tape machines or guitars. The input is BALANCED for low noise and immunity from interference, but you can use UNBALANCED sources by wiring up the jacks as shown in the "Connectors" section earlier in this manual, although you should then keep cable lengths as short as possible to minimise interference pick-up on the cable. Unplug anything in the MIC input if you want to use this socket.

2 100Hz HI-PASS FILTER

Pressing this switch reduces the level of bass frequencies only, and is a real bonus for such a small mixer. Use this in live PA situations to reduce stage rumble or popping from microphones.

3 EQUALISER

TYPICAL EQUALISER RESPONSE LF
SWEPT MID HF The Equaliser (EQ) allows 15.0 precise manipulation of the 10.0 sound, particularly to 5.0 improve the sound of microphone sources where 0.0 the original signal is often far -5.0 from ideal due to poor -10.0 acoustics or restrictions on where to place microphones CUT-15.0 -20.0 and where slight boosting or 20 1k 10k 20k 100 Frequency/Hz cutting of particular voice frequencies can really make a difference to clarity. The EQ allows enough control to improve, for instance, bad recordings or the precision to gently enhance vocal or live instrument tracks. There are three sections, HF, MID and LF giving the sort of control usually only found on much larger mixers. The EQ knobs can have a dramatic effect, so use them sparingly and listen carefully as you change any settings so that you get to know how they affect the sound.
Turn to the right to boost high (treble) frequencies by up to 15dB at crispness to cymbals, vocals and electronic instruments. Turn to the frequencies by up to 15dB, reducing hiss or over-emphasis of consonants, which can occur with certain types of microphone. Set centre-detented position when a flat response is required. 12kHz, adding left to cut these high-frequency the knob in the

MID EQ

There are two knobs which work together to form a SWEPT MID EQ. The lower knob provides 15dB of boost and cut, just like the HF EQ knob, but the frequency at which this occurs can be set by the upper knob over a range of 250Hz to 6kHz. This allows some truly creative improvement of the signal in live situations, because this mid band covers the range of most vocals. Listen carefully as you use these controls together to find how particular characteristics of a vocal signal can be enhanced or reduced. Set the lower knob to the centre-detented position when not required.
Turn to the right to boost low (bass) frequencies by up to 15dB at 60Hz, adding warmth to vocals or extra punch to synths, guitars and drums. Turn to the left to cut low frequencies by up to 15dB for reducing hum, stage rumble or to improve a mushy sound. Set the knob to the centre-detented position when not required.

4 AUX SENDS

These controls route the input channel signal to any one or more of six Auxiliary which are used to set up separate mixes for FOLDBACK, EFFECTS or recording, and the combination of all the Aux Sends is mixed to the corresponding Aux Output at the rear of the mixer. The controls are specially chosen to give a particularly smooth and useful control range all round the scale while still maintaining nearly 90dB cut-off when turned anticlockwise. Aux 1 is always PRE-FADE and pre-EQ which is ideal for Foldback or Monitor feeds where the send needs to be independent of the fader so that, for instance, the mix to artists headphones is not affected by changes in fader level.

Aux 3 and 4 are always POST-FADE, ideal for Effects where it is useful for the Aux Send to fade up and down with the fader. For flexibility, the Master Section AUX2 PRE switch allows you to switch AUX 2 from post- to pre-fade across the whole mixer as required. Aux 5 & 6 are identical to Aux 3 & 4 and may be selected as an alternative by pressing the 5-6 switch. Leave all of the knobs turned fully left when not in use.
This control sets the amount of the channel signal feeding the pairs of Groups, allowing you to move the source smoothly across the stereo image. When the control is turned fully right or left you are able to place the signal at unity gain to either Groups 2 & 4 or 1 & 3 respectively.

6 ROUTING

This switch selects either Groups 1 & 2 (switch released) or Groups 3 & 4 (switch pressed) as the destination for the channel signal after it has passed through the PAN control.

7 FADER

The linear FADER gives you smooth control of the overall signal level in the channel strip, allowing precise balancing of the various source signals being mixed to the Master Section. You get most control when the input GAIN is set up correctly, giving a normal fader position around the 0 mark, generous control range below and some gain in hand above the mark when you need that little bit extra. See the Initial Setting Up section for help in setting a suitable signal level. Note that the post-fader signal is available as a DIRECT OUTPUT from the channel to feed tape tracks or other external equipment.

8 SOLO

The latching SOLO switch has two distinctive modes of operation, depending on the position of the master section SOLO MODE switch. When this switch is released (AFL/PFL) all channel SOLO switches function as PFL (Pre-Fade-Listen). When SOLO MODE is pressed (IN PLACE) all SOLO switches become a SOLO-IN-PLACE facility. In PFL/AFL mode, pressing the SOLO switch feeds the pre-fade channel signal to the monitor output, headphones and Right Bargraph Meter, replacing the selected source. You use this switch to listen to a channel signal without affecting the mixer outputs, to check the signal quality or simply to check that it is there! In SOLO mode, pressing one or more channel SOLO switches mutes all other channels leaving the selected channels alone in the mix. The Stereo Returns or FX Returns are not muted, and this allows the selected channels to be monitored in their true stereo position, including any effects which may have been added. The associated PEAK LED indicator normally warns when an excessively high signal level is present in the channel. The signal is sampled just after the EQ section and the LED will light approximately 4dB before clipping. This point is post-insert, and will therefore take into account the effect of any equipment connected to the Insert jack.

When the SOLO switch is pressed the LED lights continuously to show which channels are being monitored.
STEREO INPUT CHANNELs 11-14
These inputs accept 3-pole A gauge (TRS) jacks. Use these inputs for sources such as keyboards, drum machines, synths, tape machines or as returns from processing units. The inputs are BALANCED for low noise and immunity from interference, but you can use UNBALANCED sources by wiring up the jacks as shown in the "CONNECTIONS" section earlier in this manual, although you should then keep cable lengths as short as possible to minimise interference pick-up. If you wish to use the channel with a mono source, plugging into the Left jack automatically feeds the source to both sides of the channel.

1 INPUT +4/-10

Most professional equipment uses input and output levels of +4dBu, but semi-professional tape machines or hi-fi systems use a lower level of -10dBV. This switch allows you to match the sources connected to the Stereo input jacks to either standard, which is important to ensure the best possible sound quality. If you are not sure which input level is appropriate, start with the switch UP to select +4dBu. If you are unable to achieve an adequate signal level (even with the fader at maximium), press the switch in for -10dBV.

2 EQUALISATION

Turn to the right to boost high (treble) frequencies, adding crispness to percussion from drum machines, synths and electronic instruments. Turn to the left to cut these frequencies, reducing hiss or excessive brilliance. Set the knob in the centre-detented position when not required. The control has a shelving response giving 12dB of boost or cut at a fixed frequency of 12kHz.
Turn to the right to boost low (bass) frequencies, adding extra punch to synths, guitars and drums. Turn to the left to reduce hum, boominess or improve a mushy sound. Set the knob to the centre-detented position when not required. The control has a shelving response giving 12dB of boost or cut at a fixed frequency of 60Hz.

3 AUX SENDS

These controls route a mono sum of the channel signal to any one or more of six Auxiliary which are used to set up separate mixes for FOLDBACK, EFFECTS or recording, and the combination of all the Aux Sends is mixed to the corresponding Aux Output at the rear of the mixer. The controls are specially chosen to give a particularly smooth control range at the lower end of the scale where it is most needed - quite unique on a mixer of this type. Aux 1 is always PRE-FADE which is ideal for Foldback or Monitor feeds where the send needs to be independent of the fader so that, for instance, the mix to artists headphones is not affected by changes in fader level. Aux 3 and 4 are always POST-FADE, ideal for Effects where it is useful for the Aux Send to fade up and down with the fader. For flexibility, the Master Section AUX2 PRE switch allows you to switch AUX 2 from pre- to post-fade across the whole mixer as required. Aux 5 & 6 are identical to Aux 3 & 4 and may be selected as an alternative by pressing the 5-6 switch. Leave all of the knobs turned fully left when not in use.

4 BALANCE

This control sets the amount of the channel signal feeding the pairs of Groups, allowing you to balance the source in the stereo image. When the control is turned fully right or left you feed only that side of the signal to the Groups selected by the Routing switch (see below).

5 ROUTING

This switch selects either Groups 1 & 2 (switch released) or Groups 3 & 4 (switch pressed) as the destination for the channel signal after it has passed through the BAL control.

6 FADER

The linear FADER gives you smooth control of the overall signal level in the channel strip, allowing precise balancing of the various source signals being mixed to the Master Section. It is important that the input level is set correctly with the +4/-10 switch to give maximum travel on the fader which should normally be used at around the 0 mark. See the Initial Setting Up section for help in setting a suitable signal level.

7 SOLO

The latching SOLO switch has two distinctive modes of operation, depending on the position of the master section SOLO MODE switch. When this switch is released (AFL/PFL) all channel SOLO switches function as PFL (Pre-Fade-Listen). When SOLO MODE is pressed (IN PLACE) all SOLO switches become a SOLO-IN-PLACE facility. In PFL/AFL mode, pressing the SOLO switch feeds a mono sum of the pre-fade channel signal to the monitor output, headphones and Right Bargraph Meter, replacing the selected source. You use this switch to listen to a channel signal without affecting the mixer outputs, to check the signal quality or simply to check that it is there! In SOLO mode, pressing one or more channel SOLO switches mutes all other channels leaving the selected channels alone in the mix. The Stereo Returns or FX Returns are not muted, and this allows the selected channels to be monitored in their true stereo position, including any effects which may have been added.
When the SOLO switch is pressed the associated LED lights continuously to show which channels are being monitored.

STEREO RETURNS

There are four Stereo Returns, which have similar controls but different routing configurations to provide the maximum flexibility. Each Return has an unbalanced stereo input on 3-pole A gauge (TRS) jacks. If a mono source is to be used, plugging into the Left jack automatically feeds the signal equally to both sides of the Return.

1 LEVEL

The LEVEL control sets the overall signal level, and enough gain is available to match both +4dBu and -10dBV sources. Rotation clockwise increases the gain of the input.

2 AUXILIARY SENDS

Each Return may access Aux 1 (Pre-fade) and one of the post-fade sends. Returns A & C feed to Aux 3 and Returns B & D feed to Aux 4. The controls should be turned fully anticlockwise when not in use.

3 BALANCE

This control sets the amount of the channel signal feeding the pairs of Groups or Mix, allowing you to balance the source in the stereo image. When the control is turned fully right or left you feed only that side of the signal to the destination selected by the Routing switch (see below).
When the PFL (Pre-Fade-Listen) switch is pressed a mono sum of the pre-fade signal is fed to the headphones or monitor output, replacing the selected source. The PFL LED on the Master section illuminates to warn that the headphones, monitor and right bargraph meter are now responding to the PFL/AFL selection.
This switch selects either a pair of Groups (switch released) or Mix (switch pressed) as the destination for the Stereo Return signal after it has passed through the BAL control. Returns A & B route to Groups 1 & 2, and Returns C & D route to Groups 3 & 4. The left return signal feeds the odd-numbered Group or Mix Left, while the right return signal feeds the even-numbered Group or Mix Right.
MASTER SECTION 1 GROUP FADERS
Four Group FADERS set the overall level of the Groups, allowing the combined control of a selected number of input sources. The Groups may feed external equipment directly through the ground compensated Group output jacks, or may be mixed together to the stereo Mix output (see below). The faders should normally be set close to the 0 mark if the input GAIN settings have been correctly set, giving plenty of control below the mark and additional gain in hand if required.

2 GROUPS TO MIX

Pressing this switch routes all Groups to the main stereo Mix. Groups 1 & 3 feed Mix Left and Groups 2 & 4 feed Mix Right.

3 MIX FADER

A stereo fader controls the output level of the stereo Mix. The outputs are ground compensated 3-pole A gauge (TRS) jacks. The Mix Left and Right signal paths have pre-fade INSERT points which provide a means of diverting the signal to an external processing unit such as a compressor or limiter. Inserting a jack into the insert breaks the signal path and allows the INSERT SEND (on the tip of the jack) to feed the input of the external unit and the INSERT RETURN (on the ring of the jack) to receive the corresponding output. Note that if the tip and ring of the jack are shorted together the signal path remains unbroken and the Insert may then be used as a way of tapping off the Mix signal before the fader.

TRACK (2TK) RETURN LEVEL

The unbalanced 2TK return jacks are an ideal place to connect the playback of a tape machine, without using up any of the LINE inputs. This control sets the level of playback signal fed either to the MIX (when 2TK TO MIX is pressed) or the headphones or monitor output, when 2TK is pressed. When set fully clockwise the inputs will be matched to -10dBV sources, or will suit a +4dBu source with the LEVEL control at a lower setting. A mono source may be fed automatically to both left and right by plugging into the Left return jack only. The 2TK RETURN is also the best way of connecting a tape or CD player to feed pre-show music to a PA rig, since this leaves all input settings unaltered. It can also serve as the return from an Effects unit to save using up Line Inputs.

5 2TK TO MIX

Press this switch to route the 2TK RETURN signal directly to the mix outputs. Adjust the input level with the 2TK RETURN LEVEL control. The 2TK Return signal will now be present at the Mix outputs, at a level set by the Master Fader.
6 C/ROOM & PHONES SECTION
The rotary control sets the output level to the MONITOR LEFT & RIGHT outputs. If HEADPHONES are plugged into the PHNS jack the Monitor outputs are cut off, and the knob then sets the headphone listening level. When the PHONES are unplugged the Monitor output is restored. The section may listen to a choice of sources: 2TK Return, Groups and Mix as selected on the four switches. The selected source is also displayed on the bargraph meters. If any PFL or AFL switch is pressed the selected signal is replaced by the appropriate PFL or AFL signal, which will also be displayed on the right bargraph meter.

AUXILIARY MASTERS

The Master section houses the summing amplifiers for each of the Auxiliary Send , and feeds the signal via ground compensated output amplifiers to the Auxiliary Output jacks.

7 AUX AFL

The individual outgoing Aux signals may be monitored on the control room outputs or headphones by pressing the appropriate AFL (After-Fade-Listen) switch. The selected signal is also displayed on the right bargraph meter.

8 AUX 2 PRE

Aux 2 is normally post-fade, but for flexibility it may be switched to pre-fade by pressing the AUX 2 PRE switch. This simultaneously affects all Aux 2 sends across the mixer.

9 SOLO MODE

All channel SOLO switches are normally a non-destructive PFL (Pre-Fade-Listen). When SOLO MODE is pressed, SOLO-IN-PLACE mode is activated. If any channel SOLO switch is pressed the SIP LED will illuminate and all other channels (but not Stereo, FX or 2TK Returns) are cut, leaving the selected channel, complete with effects in the mix. While SOLO-IN-PLACE is active, if any PFL or AFL switch is pressed the C/Room & Phones and meters will silently switch over to monitor the selected signal, but the mix output will remain. Releasing the AFL/PFL re-instates the solo signal.

10 FX RETURNS

The unbalanced FX Return jacks are an ideal place to connect the output of an effects unit, without using up any of the LINE inputs. This control sets the level of the signal fed directly to the MIX. When set fully clockwise the inputs will be matched to -10dBV sources, or will suit +4dBu sources with the controls at a lower setting. A mono source may be fed automatically to both left and right by plugging into the Left return jack only. A CUT switch mutes both FX Returns if required.

11 BARGRAPH METERS

The three colour BARGRAPH METERS have a PEAK response and normally follow the Monitor selection, giving you a constant warning of excessive peaks in the signal which might cause overloading. The fast attack of the meters means that a signal with high level transients (e.g. kick drum) will tend to give a higher reading than a less dynamic signal (e.g. a synth) at the same level. You should therefore aim for an average reading of +6/+9 if the mix contains a high proportion of high level transients and a lower reading of around 0 for steadier signals with the Master Faders at about the 0 mark. If the output level is too low and hardly registering at all on the meters, the level of background noise may become significant. In this case check that input levels and gain settings are correct (see the section -- Initial Setting Up) When an AFL or PFL switch is pressed the selected meter signal is muted and the right meter will display the selected PFL/AFL signal. N.B. The 0 position on the meters corresponds to +4dBu at the selected output.

12 PHANTOM POWER

Many professional condenser mics need PHANTOM POWER, which is a method of sending a powering voltage down the same wires as the mic signal. Press the switch to enable the +48V power to the MIC inputs on channels 1-10. DO NOT turn on the phantom power when using unbalanced mics which may be damaged by the voltage applied to pin 2 & 3 of the mic input XLR. Note: Mics should always be plugged in before switching the Phantom Power ON.

Applications

Multitrack Recording
This example illustrates how Rac Pac may be set up for multitrack recording to eight tracks. Individual instrument or vocal tracks are recorded on Digital Multitracks by connecting the channel Direct Outputs to the tape inputs. The outputs from the Multitrack are brought back on the Stereo Returns (or spare mono channels if only one or two tracks are being recorded). A compressor is included on the insert of one of the vocal channels. An Artists Phones mix is derived from Aux 1 (or Aux 2 selected pre-fade).

Stereo Public Address

In this basic PA set-up, various sources are connected to the inputs, microphones to Mic inputs and keyboards etc. to Line inputs. Note that some guitars will not produce sufficient level for a direct connection, and will require a Direct Injection (DI) box connected via the microphone input. The mic channel has a compressor/limiter included in the insert point and a feed to a reverb unit from the direct output. The reverb output is brought back to the mix on FX Return 1. The output is taken from Mix L & R and connected to the speakers via a suitable power amplifier. A compressor/limiter (or graphic equaliser if required) is included in the Mix Inserts, and a cassette machine connects to the 2TK Return to provide interval music. The Groups may be used to combine several inputs under the control of a single fader before mixing to the L & R outputs.

Relocating the connector panel
The connector panel is fitted as standard to the rear of the frame, allowing the mixer to be used as a free-standing, desktop unit. If the mixer is to be rack-mounted, it may be found more convenient to move the connector panel to the optional position in the base of the frame, opposite the front panel, giving rear access to connectors when fitted in the rack. A cover plate is mounted in the alternative position, and this is swapped with the connector panel in a straightforward procedure described below: Carefully lay the mixer face down on a flat surface provided with some protective padding. During the following steps take care not to apply excessive pressure or damage the control knobs. Using a cross-head screwdriver remove the four screws "A" (2 each side) fixing the cover plate through the side panels of the mixer. Release the cover plate by next removing the six screws "B" fixing the plate to the base panel and connector panel. Lay the cover plate to one side. Now remove the three screws "D" fixing the connector panel to the top edge of the mixer. The connector panel will still be supported by the fixings through the side panels. Loosen the four screws "C" fixing the connector panel to the side panels. Now, supporting the connector panel with one hand, remove the four screws completely, freeing the panel. Swapping the supporting hand, rotate the panel backwards, taking care not to strain or snag any of the ribbon cables, so that the bottom edge now rests on the flange of the base panel, and loosely fit the screws ("A", 4 off) once again through the side panels. Pick up the cover plate and, turning it lengthways locate it in the position originally occupied by the connector panel. (Note that the cover plate has one flat edge, and one folded flange. The folded edge ALWAYS faces the back corner of the mixer.) Loosely fit the four screws "C" through the side panels, three screws "D" at the top edge, and six screws "B" fixing the connector panel. Once you are satisfied that the panels are seated correctly, tighten all screws firmly.

AFL (After Fade Listen) Balance Balanced a function that allows the operator to monitor the post-fade signal in a channel independently of the main mix. the relative levels of the left and right channels of a stereo signal. a method of audio connection which balances the signal between two wires and a screen which carries no signal. Any interference is picked up equally by the two wires, but out of phase resulting in cancellation of the interference signal. the onset of severe distortion in the signal path, usually caused by the peak signal voltage being limited by the circuits power supply voltage. a ratio of two voltages or signal levels, expressed by the equation dB=20Log10 (V1/V2). Adding the suffix u denotes the ratio is relative to 0.775V RMS. (direct injection) the practice of connecting an electric musical instrument directly to the input of the mixing console, rather than to an amplifier and loudspeaker which is covered by a microphone feeding the console. the use of devices to alter or process the sound to add special effects e.g. reverb, normally as a mix of the original (dry) sound and the treated version. a device that allows the boosting or cutting of selected bands of frequencies in the signal path. the howling sound caused by bringing a microphone too close to a loudspeaker driven from its amplified signal. a feed sent back to the artistes via loudspeakers or headphones to enable them to monitor the sounds they are producing. the variation in gain of a device with frequency. a technique used on unbalanced outputs to cancel out the effect of ground loops caused by connections to external equipment. the available signal range above the nominal level before clipping occurs. a filter that rejects low frequencies. at a nominal level of -10 to +6dBu, usually coming from a low impedance source. a built-in tone generator for test and line-up purposes. an equaliser response curve affecting only a band of frequencies i.e. based on a bandpass response. a function that allows the operator to monitor the pre-fade signal in a channel independently of the main mix. the +48V d.c. voltage applied equally to the two signal pins of a balanced mic input to provide powering for condenser microphones. the point in the signal path after the channel or master fader and therefore affected by fader position. a device which affects the whole of the signal passing through it, e.g. gate, compressor or equaliser a fall in gain at the extremes of the frequency response. an equaliser response affecting all frequencies above or below the break frequency i.e. a highpass or lowpass derived response. a expression of the difference in level between the audio signal and background system noise. a function that allows the operator to listen to a selected channel on its own but complete with all relevant effects, by automatically muting all other inputs. acoustic interference from other sources. an Equaliser section ( e.g. MID EQ) which operates at a variable rather than fixed frequency giving increased flexibility to the user. the operator speaking to the artistes or to tape via the auxiliary or group outputs. a line level input provided specifically to receive the playback output of a tape machine a momentary rise in the signal level. a 3-pole jack with Tip, Ring and Sleeve connections a methode of audio connection which uses a single signal wire and the cable screen as the signal return. This method does not provide the noise immunity of a balanced input (see above).
