These keys place the console into MIX mode allowing quick & easy mixing from Channels to Buses, Channels to FX or Buses to Matrix. Pressing any key triggers a sequence of events that re-configure the control surface and console monitoring system to the optimum layout for the desired/required function. Aux Buses 1:14 Clears all current SOLOs. Sets fader bank to IN A (if not currently on IN A or IN B bank). Puts input faders into sends on faders mode lighting fader glow according to the PRE or POST setting of the bus. Places BUS MASTER for selected bus on the MONO fader. SOLOs the selected bus. Selects the ACS to the appropriate Aux bus. FX Buses 1:4 Clears all current SOLOs. Sets fader bank to IN A (if not currently on IN A or IN B bank). Puts faders into sends on faders mode lighting fader glow accordingly. Places FX Return of fader for selected bus on the MONO fader. SOLOs the appropriate FX Return channel. Selects the ACS to the appropriate FX Return channel. NOTE: This function may only be enabled if an FX processor is patched to a Stereo Return channel; this is achieved from the PATCH function in the inputs window. Matrix Buses 1:4 Clears all current SOLOs. Puts faders into BUS mode if not currently already selected. Puts faders into sends on faders mode lighting fader glow accordingly. Places MATRIX MASTER for selected bus for selected bus on the MONO fader. SOLOs the selected bus. Selects the ACS to the appropriate Matrix bus. NOTE: Use ALT + MTX to have MONO and LR faders send to the selected matrix MONO, L&R meters.

FADER LAYER KEYS

Fader Layer Keys change the function of the faders to the LEFT of the L/R Master faders: 1. INA: Input Layer A, nominally all MONO inputs to the system 2. INB: Input Layer B, nominally all STEREO inputs to the system 3. BUS: All Aux Bus Masters in the system 4. MTX: All Matrix Masters in the system 5. GEQ LO: The lower half of the GEQ 6. GEQ HI: The upper half of the GEQ NOTE: The GEQ pages are only available when in BUS or MTX mode, when the L/R or MONO master is SELected or when FOLLOWing a bus.

FADER GLOWTM

The Fader Glow system illuminates the fader slot when the function of the fader is anything other than a mono input channel level control according to the following list: White: Yellow: Green: Orange: Red: Cyan: Magenta: Channel faders linked Faders in BUS mode, bus type is PRE FADE or faders in FOLLOW mode to a PRE FADE aux bus Faders in BUS mode, bus type is POST FADE or faders in FOLLOW mode to a POST FADE aux bus Faders in matrix master OR faders in FOLLOW mode to a MATRIX bus Faders in GEQ mode A channel assigned as an FX Return or faders in FX follow mode Channel Faders assigned to Stereo channels
PATCHING AND FADER LAYERS
The fader layers on Si Compact are arranged in a simple and logical form, by default the fader layers are as follows:
IN A: all MONO channels (16ch: 1-14, 24ch: 1-22, 32ch 1-30) IN B: all STEREO channels (16ch: 15-24, 24ch: 23-32, 32ch 31-40) BUS: all Aux Buses (1-14) MTX: all Matrix Buses (1-4)
The Fader Glow system indicates the type of channel, bus or function is associated with any given fader on the surface. The patching system on Si Compact is very flexible and allows almost any physical input to be patched to any logical channel; the default patches on the Si Compact are as follows: Si COMPACT 16 FADER INPUT PATCHING & LAYERS:
Mic In 1-14 > Channels 1-14 > Fader Layer IN A faders 1-14 Mic In 15-16*1 > Channels 15-16 > Fader Layer IN B faders 1-2 Ste IN Returns 1-2 > Channels 17-20 > Fader Layer IN B faders 3-4 Ste FX Returns 3-4 > Channels 21-24 > Fader Layer IN B faders 5-6
Si COMPACT 24 FADER INPUT PATCHING & LAYERS:
Mic In 1-22 > Channels 1-22 > Fader Layer IN A faders 1-22 Mic In 23-24*1 > Channels 23-24 > Fader Layer IN B faders 1-2 Ste IN 1-2 > Channels 25-28 > Fader Layer IN B faders 3-4 Ste FX Returns 3-4 > Channels 29-32 > Fader Layer IN B faders 5-6
Si COMPACT 32 FADER INPUT PATCHING & LAYERS:
Mic In 1-30 > Channels 1-30 > Fader Layer IN A faders 1-30 Mic In 31-32*1 > Channels 31-32 > Fader Layer IN B faders 1-2 Ste IN 1-2 > Channels 33-36> Fader Layer IN B faders 3-4 Ste FX Returns 1-2 > Channels 37-40 > Fader Layer IN B faders 5-6

Channels are set-up as a Linked Pair
Si COMPACT OUTPUT PATCHING & LAYERS: As all Si Compact models offer the same level of output processing and number of physical output all models have the same Output Layers & Patching system:
Buses 1-14 > Fader Layer BUS faders 1-14 > Analogue Line Out 1-14 MTX 1-4 > Fader Layer MTX faders 1-4 > Not Assigned Main L&R > Master L&R Fader > Analogue Line Out 15-16 MONO > MONO/SEL Fader > Not Assigned
NOTE: Any 'unused' faders and associated switches, meters and encoders are unlit and have no function.
NOTE: Patching can be set or changed from the INPUT or OUTPUT menu as appropriate.

WIRING UP

Mic Input The MIC input accepts XLR-type connectors and is designed to suit a wide range of BALANCED or UNBALANCED signals, whether from delicate vocals requiring the best low-noise performance to drum kits to high level line sources.
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. BALANCED dynamic mics may normally be used with phantom power switched on (contact your microphone manufacturer for guidance)
Stereo Line Inputs Accepts 3-pole 6.35mm (1/4") jacks, or 2-pole mono jacks which will automatically ground the cold input. Use these for input for sources such as keyboards, drum machines, synths, CD players etc. The input is BALANCED for low noise and immunity from interference, but you can use UNBALANCED sources by wiring up the jacks as shown, although you should then keep cable lengths as short as possible to minimize interference pick-up on the cable. NOTE: The ring must be grounded if the source is unbalanced

Insert Returns Accepts 3-pole 6.35mm (1/4") jacks, or 2-pole mono jacks which will automatically ground the cold input. Use this when utilizing the Insert Send & Return functions to allow insertion of special effect or dynamic processors. AES Input: This is a balanced 2-channel digital input using a single XLR wires as per the balanced mic inputs. Although it is possible to use standard balanced audio cable with AES signals it is recommended to use AES cable which has the correct 110R impedance.

Line Outputs

Line Outputs The 16 Line outputs are wired as shown and are fully balanced allowing long cable runs to other equipment. If connecting to un-balanced destinations the Signal (cold) pin should be grounded. AES Output: This is a balanced 2-channel digital output using a single XLR wired as per the balanced line outputs. Although it is possible to use standard balanced audio cable with AES signals it is recommended to use AES cable which has the correct 110R impedance.
Aux Outputs Group Outputs
Insert Sends Accepts 3-pole 6.35mm (1/4") jacks, or 2-pole mono jacks which will automatically ground the cold output. The connector is wired as shown. Use this when utilizing the Insert Send & Return functions to allow insertion of special effect or dynamic processors. Headphones The PHONES output is a 3-pole 6.35mm (1/4) jack, wired as a stereo output as shown, ideally for headphones of 32 or greater; 8 headphones are not recommended. The headphone socket is found under the front edge, close to fader 1.

Polarity (Phase) You will probably be familiar with the concept of polarity in electrical signals and this is of particular importance to balanced audio signals. Just as a balanced signal is highly effective at cancelling out unwanted interference, so two microphones picking up the same signal can cancel out, or cause serious degradation of the signal if one of the cables has the +ve and -ve wires reversed. This phase reversal can be a real problem when microphones are close together and you should therefore always take care to connect pins correctly when wiring audio cables. Grounding and Shielding For optimum performance use balanced connections where possible and ensure that all signals are referenced to a solid, noise-free earthing point and that all signal cables have their screens connected to ground. In some unusual circumstances, to avoid earth or ground loops ensure cable screens and other signal earths are connected to ground only at their source and not at both ends. If the use of unbalanced connections is unavoidable, you can minimise noise by following these wiring guidelines: On INPUTS, unbalance at the source and use a twin screened cable as though it were balanced. On OUTPUTS, connect the signal to the +ve output pin, and the ground of the output device to -ve. If a twin screened cable is used, connect the screen only at the mixer end. Avoid running audio cables or placing audio equipment close to thyristor dimmer units or power cables. Noise immunity is improved significantly by the use of low impedance sources, such as good quality professional microphones or the outputs from most modern audio equipment. Avoid cheaper high impedance microphones, which may suffer from interference over long cable runs, even with well-made cables.

USING YOUR Si Compact CONSOLE
The final output from your sound system can only ever be as good as the weakest link in the chain, and especially important is the quality of the source signal because this is the starting point of the chain. Just as you need to become familiar with the control functions of your mixer, so you must recognise the importance of correct choice of inputs, microphone placement and input channel settings. However, no amount of careful setting up can take account of the spontaneity and unpredictability of live performance. The mixer must be set up to provide spare control range to compensate for changing microphone position and the absorption effect of a large audience (different acoustic characteristics from soundcheck to show).
Microphone Placement Careful microphone placement and the choice of a suitable type of microphone for the job is one of the essentials of successful sound reinforcement. The diagrams on the left show the different pick-up patterns for the most common types of microphone. Cardioid microphones are most sensitive to sound coming from in front, and hypercardioid microphones offer even greater directivity, with a small amount of pickup behind the microphone. These types are ideal for recording vocalists or instruments, where rejection of unwanted sounds and elimination of feedback is important. The aim should be to place the microphone as close as physically possible to the source, to cut out unwanted surrounding sounds, allow a lower gain setting on the mixer and avoid feedback. Also a well chosen and well placed microphone should not need any appreciable equalisation. There are no exact rules, let your ears be the judge. In the end, the position that gives the desired effect is the correct position! Initial SetUp Once you have connected up your system (see the sections on connection and wiring earlier in this manual for guidance) you are ready to set initial positions for the controls on your mixer. Set up individual input channel as follows: Connect your sources (microphone, keyboard etc.) to the required inputs. WARNING: Phantom powered mics should be connected before the +48V is switched on. Ensure the PA system is OFF when switching phantom power on or off. Set Master faders at 0, input faders at 0, and set power amplifier levels to about 70%. Provide a typical performance level signal and press the PFL button on the first channel, monitoring the level on the bargraph meters. Adjust the input gain until the meter display is in the amber section, with occasional peaks to the first red LED at a typical maximum source level. This allows sufficient headroom to accommodate peaks and establishes the maximum level for normal operation (but see note below). Repeat this procedure on other channels as required. As more channels are added to the mix, the meters may move into the red section. Adjust the overall level using the Master Faders if necessary. Listen carefully for the characteristic sound of feedback. If you cannot achieve satisfactory input level setting without feedback, check microphone and speaker placement and repeat the exercise. If feedback persists, it may be necessary to use a Graphic Equaliser to reduce the system response at particular resonant frequencies.

GLOSSARY AFL AUXiliary send Balance Balanced After-fade listen: a function that allows the operator to monitor the post-fade signal in a channel independently of the main mix. An output from the console comprising a mix of signals from channels derived independently of the main stereo mix. The relative levels of the left and right channels of a stereo signal. A method of audio connection which balances the wanted signal between two wires, these wires also have a screen which carries no signal. Any interference is picked up equally by the two wires, which results in cancellation of the unwanted signal. In this guide, the term can refer to various circuit architectures. Connection details are given in relevant sections. The onset of severe distortion in the signal path, usually caused by the peak signal voltage being limited by the circuits power supply voltage. Dynamic audio process used to squash the amplitude of the signal effectively reducing the level of this highest audio peaks Digital Audio Tape, a cassette-based digital recording format. 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.
Clipping Compressor DAT dB (decibel)
DI(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 DI Box feeding the console. Equaliser Fader Feedback Foldback A device that allows the boosting or cutting of selected bands of frequencies in the signal path. A linear control providing level adjustment. 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 amount of amplication in level of the signal. The available signal range above the nominal level before clipping occurs.
Frequency response The variation in gain of a device with frequency. Gain Headroom
Impedance balancing A technique used on unbalanced outputs to minimise the effect of hum and interference when connecting to external balanced inputs. Insert A break point in the signal path to allow the connection of external devices, for instance signal processors or other mixers at line level signals. Nominal levels can be anywhere between 0dBu to +6dBu, usually coming from a low impedance source. Abbreviation of panorama: controls the levels sent to left and right outputs. The point at which a signal rises to its maximum instantaneous level, before falling back down again. It can also describe an equaliser response curve affecting only a band of frequencies, (like on a graphic equaliser), peaking at the centre of that band. A visual indication of the signal peaking just before the onset of clipping, which will distort the signal.
