Behringer Xenyx X1222USB Manuel D’Utilisation

XENYX X1222USB User Manual

MON SEND
The aux send control MON SEND acts as master control for the monitor bus and 

determines the level of the summed signal that is taken from the mixer via 

the MON SEND connector and that can for example be fed to an amplifier for 

monitor purposes.
Using the audio signal from this output, you can also feed a subwoofer if you 

don’t require stage monitors. To this end, you should implement a crossover in 

your signal path pre-subwoofer and pre-amplifier, so that only low frequencies 

are fed into the subwoofer. You can achieve the same effect by using the built-in 

graphical equalizer. Lower all frequencies above 160 Hz and assign the equalizer 

to “Monitor”.

FX TO MON
You can use this control to insert an effects signal from the built-in effects 

processor to your monitor mix. Of course, to do this, your effects processor must 

first receive a signal, i.e. the FX controls in the channel strips must be turned up, 

and the FX SEND fader (see fig. 2.6) hast to be open.

MON MUTE
If the MON MUTE switch is pressed, the monitor bus is muted, i.e. there is no 

signal at the MON SEND connector.

FX SEND
The FX SEND fader determines the overall level of the effects bus. Both external 

effects processors (via the FX SEND connector) and the built-in processor only 

receive an input signal if this control is open.

FX TO MAIN
Use the FX TO MAIN control to feed the effects signal into the main mix. 

If the control is turned all the way to the left, no effects signal can be heard.

FX MUTE
If the FX MUTE switch is pressed, the effects channel is muted, i.e. no signal is 

present at the FX SEND connector and the effects processor no longer receives an 

input signal.

MON SEND 
Connect the input of your monitor power amp or an active monitor system here 

to make the monitor mix audible to the musicians on the stage. The signal mix is 

created using the channels’ MON controls. 

FX SEND
The FX SEND connector outputs the signal you picked up from the individual 

channels using the FX controls. You can connect this to the input of an external 

effects device in order to  process the FX bus’ master signal. Once an effects mix is 

created, the processed signal can then be routed from the effects device outputs 

back into the AUX RETURN connectors.

AUX RETURN 1
The AUX RETURN 1 connectors generally serve as the return path for the effects 

mix generated using the FX send. This is where you connect the output signal 

of the external effects device. If only the left connector is used, the aux return 1 

automatically operates in mono.

AUX RETURN 2
The AUX RETURN 2 connectors are used exactly the same way as the AUX RETURN 

1 connectors. If these connectors already function as additional inputs, you 

can route the effects signal back into the console via a different stereo channel, 

with the added benefit that the channel EQ can be used to adjust the frequency 

response of the effects return signal.

This channel, intended especially for connecting stereo signal sources 

(CD players, DAT recorders or even sound cards) features a particularly 

practical feature: the VOICE CANCELLER.
