1. Introduction

The microphone channels feature high-end XENYX Mic Preamps that compare well with costly outboard preamps in terms of sound quality and dynamics and boast the following features:
130 dB dynamic range for an incredible amount of headroom A bandwidth ranging from below 10 Hz to over 200 kHz for crystal-clear
1.1 General mixing console functions
A mixing console fulfils three main functions:
Signal processing: Preamplification, level adjustment, mixing of effects,

frequency equalization.

Signal distribution: Summing of signals to the aux sends for effects
reproduction of even the finest nuances
The extremely low-noise and distortion-free circuitry guarantees absolutely
processing and monitor mix, distribution to one or several recording tracks, power amp(s), control room and 2-track outputs.
Mix: Setting the volume level, frequency distribution and positioning of the
natural and transparent signal reproduction
They are perfectly matched to every conceivable microphone with up to
60dB gain and +48 volt phantom power supply
They enable you to use the greatly extended dynamic range of your
individual signals in the stereo field, level control of the total mix to match the recording devices/crossover/power amplifier(s). All other mixer functions can be included in this main function. The interface of BEHRINGER mixing consoles is optimized for these tasks enabling you to easily keep track of the signal path.
24-bit/192 kHz HD recorder to the full, thereby maintaining optimal audioquality British EQ The equalizers used for the XENYX Series are based on the legendary circuitry of top-notch consoles made in Britain, which are renowned throughout the world for their incredibly warm and musical sound character. Even with extreme gain settings these equalizers ensure outstanding audio properties. Multi-effects processor Additionally, your XENYX mixing console has an effects processor with 24-bit A/D and D/A converters included, which gives you 100 presets producing first-class reverb, delay and modulation effects plus numerous multi-effects in excellent audio quality. The XENYX mixing consoles are equipped with a state-of-the-art switchedmode power supply (SMPS). Unlike conventional circuitry an SMPS provides an optimum supply current regardless of the input voltage. And thanks to its considerably higher efficiency a switched-mode power supply uses less energy than conventional power supplies. USB/Audio interface The USB interface supplied with the unit is a perfect match for the XENYX Series and serves as a powerful recording interface to your PC or MAC. It supports the digital transmission of signals on up to four channels with max. 48 kHz and extremely low latency. When wired to the CD/TAPE INPUT and OUTPUT connectors, the interface transfers the stereo mix from the console directly to a computer. Both the recording signal and the playback signal from the computer can be monitored at the same time. In this way, you can use several recording runs to produce complete multi-track recordings.

Fig. 2.4: Panorama and routing controls
2.2.4 Routing switch, solo and channel fader BAL The function of the BAL(ANCE) control corresponds to the PAN control in the mono channels. The balance control determines the relative proportion between the left and right input signals before both signals are routed to the main stereo mix bus. The MUTE/ALT 3-4 switch, the MUTE-LED, the CLIP-LED, the SOLO switch and the channel fader function in the same way as the mono channels.
2.3 Connector panel and main section
Whereas it was useful to trace the signal flow from top to bottom in order to gain an understanding of the channel strips, we now look at the mixing console from left to right. The signals are, so to speak, collected from the same point on each of the channel strips and then routed to the main section all together. 2.3.1 Aux sends 1 and 2 A channel signal is routed to aux send bus 1 if the AUX 1 control is turned up on the corresponding channel. AUX SEND 1 (MON) The AUX SEND control MON acts as master control for aux send 1 and determines the level of the summed signal. In the 1204FX, the MON control is called AUXSEND 1. AUX SEND 2 (FX) Similarly, the FX control (AUX SEND 2) determines the level for aux send 2. SOLO You can use the SOLO switch (1204FX only) to separately monitor the aux sends via the CONTROL ROOM/PHONES outputs and check these with the level meters.
If you want to monitor the signal of just one AUX bus, none of the other

2.2 Stereo channels

2.2.1 Channel inputs Each stereo channel has two balanced line level inputs on " connectors for left and right channels. If only the connector marked L is used, the channel operates in mono. Stereo channels are designed to handle typical line level signals. Both inputs can also be used with unbalanced jacks. LEVEL
Fig. 2.5: Stereo channel inputs and LEVEL switch
SOLO SWITCHES should be pressed and the MODE switch must be in the SOLO position (not pressed down). 2.3.2 Aux send connectors 1 and 2 AUX SEND 1 If you use aux send 1 pre-fader, you would usually connect the AUX SEND 1 connector to monitors via a power amp (or an active monitor system). If you use aux send 1 post-fader, proceed as described under auxsend2. AUX SEND 2
Fig. 2.7: Aux send connectors
For level matching, the stereo inputs feature a LEVEL switch which selects between +4 dBu and -10 dBV. At -10dBV (home-recording level), the input is more sensitive than at +4 dBu (studio level). 2.2.2 Equalizer stereo channels The equalizer of the stereo channels is, of course, stereo. The filter characteristics and crossover frequencies are the same as those of the mono channels. A stereo equalizer is always preferable to two mono equalizers if frequency correction of a stereo signal is needed. There is often a discrepancy between the settings of the left and the right channels when using separate equalizers. 2.2.3 Aux sends stereo channels In principle, the aux sends of the stereo channels function in just the same way as those of the mono channels. As aux send paths are always mono, the signal on a stereo channel is first summed to mono before it reaches the aux bus.

The AUX SEND 2 connector outputs the signal you picked up from the individual channels using the FX control. You can connect this to the input of an effects device in order to process the FX bus signal. Once an effects mix is created, the processed signal can then be routed from the effects device output back into the STEREO AUX RETURN connectors.
2.3.3 Stereo aux return connectors STEREO AUX RETURN 1 The STEREO AUX RETURN 1 connectors generally serve as the return path for the effects mix generated using the post-fader aux send. This is where you connect the output signal of the external effects device. If only the left connector is used, the AUX RETURN automatically operates in mono.
You can also use these connectors as
MAIN MIX/ALT 3-4 The MAIN MIX/ALT 3-4 switch routes the signal connected to STEREO AUX RETURN 2 to either main mix (not pressed) or submix (Alt 3-4, pressed). 2.3.5 Tape input / tape output CD/TAPE INPUT
Fig. 2.8: Stereo aux return connectors
additional line inputs. STEREO AUX RETURN 2 The STEREO AUX RETURN 2 connectors serve as the return path for the effects mix generated using the FX control. If these connectors already function as additional inputs, you can route the effects signal back into the console via a different channel, with the added benefit that the channel EQ can be used to adjust the frequency response of the effects return signal.
In this instance, the FX control of the channel being used as an effects
The CD/TAPE INPUT RCA connectors are provided for connecting a 2 track machine (e.g. DAT recorder). Theycan also be used as stereo line input. Alternatively, the output signal of a second XENYX or BEHRINGER ULTRALINK PRO MX882 can also be connected. If you connect a hi-fi amplifier with a Fig. 2.10: 2-track connectors source selection switch to the CD/TAPE INPUT, you can easily switch between additional sources (e.g. cassette recorder, CD player, etc.). CD/TAPE OUTPUT These connectors are wired in parallel with the MAIN OUT and carry the main mix signal (unbalanced). Connect the CD/TAPE OUTPUT to the inputs of your recording device. The final output level can be adjusted via the high-precision MAIN MIXfader.
If you connect a compressor or a noise gate after the 2-track
return should be turned fully counterclockwise, otherwise feedback problems could occur!

If you wish to use the internal effects processor, no connectors should be
plugged into STEREO AUX RETURN 2. 2.3.4 Stereo aux return STEREO AUX RETURN 1 STEREO AUX RETURN 1 is a stereo control which determines the level of the signal in the main mix. If STEREO AUX RETURN 1 is used as effects return, you can add the effects signal to any dry channelsignal.
In this instance, the effects device should

be set at 100% effect. STEREO AUX RETURN MON
Fig. 2.9: Stereo aux return controls Fig. 2.11: Control room/phones section, level meter
The STEREO AUX RETURN MON control has a special function: it can be used to add an effect to a monitor mix. For example: Monitor mix with effect In this instance, the effects device should be set up as follows: AUX SEND 2 is connected to the L/Mono input of your effects device, while its outputs are connected to STEREO AUX RETURN 1. Connect the amplifier of your monitor system to AUX SEND1. The AUX SEND 1 master control determines the volume of the monitor mix. You can now use the STEREO AUX RETURN MON control to adjust the level of the effects signal routed to the monitor mix. You can easily use the headphones distribution amplifier BEHRINGER POWERPLAY PRO HA4600/HA4700/HA8000 to provide you with four (or eight with the HA8000) stereo headphone mixes for your studio. STEREO AUX RETURN 2 (FX) The STEREO AUX RETURN 2 control determines the level of signals fed into the AUX RETURN 2 connectors which are routed to the main mix.
CD/TAPE The TAPE switch routes the signal from the TAPE IN connectors to the level meter, the CONTROL ROOM OUT outputs and the PHONES connectorthis is a simple way to check recorded signals via monitor speakers or headphones. ALT 3-4 Similarly, the ALT 3-4 switch routes the signal from the Alt 3-4 bus to the same path for monitoring purposes. MAIN MIX The MAIN MIX switch sends the main mix signal to the above-mentioned outputs and to the level meter. PHONES/CTRL R(oom) Use this control to set control room output level and head-phones volumerespectively.
CD/TAPE TO MAIN When the CD/TAPE TO MAIN switch is depressed, the 2-track input is routed to the main mix and thus serves as an additional input for tape machines. You can also connect MIDI instruments or other signal sources here that do not require any further processing. At the same time, this switch disables the main mix to tape output link. POWER The blue POWER LED indicates that the device is switched on. +48 V The red +48 V LED lights up when the phantom power supply is switched on. The phantom power supply is necessary for condenser microphones and is activated using the switch on the rear of the device.

Please do not connect microphones to the mixer (or the stagebox/
The PAN control in the channel strip offers a constant power
characteristic. This means that the signal is always at a constant level, irrespective of its position in the stereo panorama. If the PAN control is moved fully left or right from center, the level increases by 4 dB in that channel. This ensures that, when set in the center, the audio signal is not louder. For this reason, with the solo function activated (Solo in Place), audio signals from the channels with PAN controls that have not been moved fully to the left or right are displayed at a lower volume than in the PFL function. As a rule, solo signals are monitored via the control room outputs and headphones connector and are displayed by the level meters. If a solo switch is pressed, the signals from the tape input, Alt 3-4 and main mix are blocked from the control room outputs, the headphone connector and the level meter. MAIN SOLO (1204FX only) The MAIN SOLO LED lights up as soon as a channel or aux send solo switch is pressed. The MODE switch also has to be set at Solo. PFL (1204FX only) The PFL LED indicates that the peak meter is set to PFL mode. PHONES You can connect headphones to this " TRS connector. The signal on the PHONES connection is sourced from the control room output.

wallbox) while the phantom power supply is switched on. Connectmicro-phones before you switch on the power supply. Inaddition, the monitor/PA loudspeakers should be muted before you activate the phantom power supply. After switching on, wait approx. one minute to allow for system stabilization. LEVEL METER The high-precision level meter accurately displays the appropriate signal level. LEVEL SETTING: When recording to a digital device, the recorders peak meter should not exceed 0 dB. This is because, unlike analog recordings, slightly excessive levels can create unpleasant digital distortion. When recording to an analog device, the VU meters of the recording machine should reach approx. +3 dB with low-frequency signals (e.g. kick drum). Due to their inertia VU meters tend to display too low a signal level at frequencies above 1 kHz. This is why, for example, a Hi-Hat should only be driven as far as -10dB. Snaredrums should be driven to approx. 0 dB.

The peak meters of your XENYX display the level virtually independent
2.3.7 Alt 3-4 and main mix fader
of frequency. A recording level of 0 dB is recommended for all signaltypes. MODE (1204FX only) The MODE switch determines whether the channels SOLO switch operates as PFL (Pre Fader Listen) or as solo (Solo In Place). PFL To activate the PFL function, depress the MODE switch. The PFL function should, as a rule, be used for gain setting purposes. The signal is sourced pre-fader and assigned to the mono PFL bus. In the PFL setting, only the left side of the peak meter operates. Drive the individual channels to the 0 dB mark of the VU meter. Solo When the MODE switch is not depressed, the stereo solo bus is active. Solois short for Solo In Place. This is the customary method for listening to an individual signal or to a group of signals. As soon as a solo switch is pressed, allchannels in the control room (and headphones) that have not been selected are muted thereby retaining stereo panning. The solo bus can carry the output signals of the channel pan controls, the aux sends and the stereo line inputs. Thesolo bus is, as a rule, switched post-fader.
Fig. 2.13: Alt 3-4 and main mix fader
Use the high-precision quality faders to control the output level of the Alt 3-4 subgroup and main mix.

2.4.1 Main mix outputs, Alt 3-4 outputs and control room outputs
Fig. 2.14: Main mix outputs, Alt 3-4 outputs and control room outputs
MAIN OUTPUTS The MAIN outputs carry the MAIN MIX signal and are on balanced XLR connectors with a nominal level of +4 dBu. ALT 3-4 OUTPUTS The ALT 3-4 outputs are unbalanced and carry the signals of the channels that you have assigned to this group using the MUTE switch. This can be used to route a subgroup to a further mixing console for example, or or it could be used as a recording output working in tandem with the main output. This means you could record to four tracks simultaneously. The icing on the cake, so to speak, is that you could connect Y-cables to these four outputs and then connect your 8-track recorder in such a way that you have 2 x 4 tracks (e.g. channel 1 feeds track 1 and track 2, etc.). In the first recording pass, you record on tracks 1, 3, 5 and 7 and in the second pass, on tracks 2, 4, 6 and 8. CONTROL ROOM OUTPUTS The control room output is normally connected to the monitor system in the control room and provides the stereo mix or, when required, the solo signal. 2.4.2 Voltage supply, phantom power and fuse
Caution! You must never use unbalanced XLR connectors (PIN 1 and 3
connected) on the MIC input connectors if you want to use the phantom power supply. SERIAL NUMBER Please note the important information on the serial number given in chapter1.3.3.

3. Digital Effects Processor
Fig. 3.1: Digital effects module (only 1204FX)
24-BIT MULTI-EFFECTS PROCESSOR Here you can find a list of all presets stored in the multi-effects processor. This built-in effects module produces high-grade standard effects such as reverb, chorus, flanger, delay and various combination effects. The integrated effects module has the advantage of requiring no wiring. This way, the danger of creating ground loops or uneven signal levels is eliminated at the outset, completely simplifying the handling. These effect presets are designed to be added to dry signals. If you move the FXTO MAIN control, you mix the channel signal (dry) and the effect signal. This also goes for mixing effects signals with the monitor mix. The main difference is that the mix ratio is adjusted using the FX TO MON control. Of course, a signal has to be fed into the effects processor via the FX control in the channel strip for both applications.
On the following page, you will find an illustration showing how to
Fig. 2.15: Voltage supply and fuse
FUSE HOLDER The console is connected to the mains via the cable supplied which meets the required safety standards. Blown fuses must only be replaced by fuses of the same type and rating. IEC MAINS RECEPTACLE The mains connection is via a cable with IEC mains connector. An appropriate mains cable is supplied with the equipment. POWER Use the POWER switch to power up the mixing console. PHANTOM The PHANTOM switch activates the phantom power supply for the XLR connectors of the mono channels which is required to operate condenser microphones. The red +48 V LED lights up when phantom power is on. As a rule, dynamic microphones can still be used with phantom power switched on, provided that they are wired in a balanced configuration. In case of doubt, contact the microphone manufacturer!
After the phantom power supply has been switched on, do not connect
connect your foot switch correctly. LEVEL The LED level meter on the effects module should display a sufficiently high level. Take care to ensure that the clip LED only lights up at peak levels. If it is lit constantly, you are overloading the effects processor and this could cause unpleasant distortion. The FX control (AUX SEND 2) determines the level that reaches the effects module. PROGRAM You can select the effect preset by turning the PROGRAM control. The display flashes the number of the current preset. To recall the selected preset, pressthe button; the flashing stops. You can also recall the selected preset with the foot switch.

Caution! You must never use unbalanced XLR connectors (pin 1 and
3 connected) on the MIC inputs if you intend to use the phantom powersupply.
