Fig. 5.1: Main Mix outputs, main mix insert points and control room outputs

MAIN OUTPUTS
The MAIN outputs carry the MAIN MIX signal and are on balanced XLR jacks with 

a nominal level of +4 dBu. In parallel with this, ¼" phone jacks carry the main 

mix signal in a balanced format (QX1622USB: here, the phone jack outputs are 

unbalanced and located on the top panel).

CONTROL ROOM OUTPUTS (CTRL OUT)
The control room output is normally connected to the monitoring system in the 

control room and carries the stereo mix or, when selected, the solo signals.

MAIN INS(ERTS) (QX2442USB only)
These are the insert points for the main mix. In the signal path, they are 

post-main mix amp, but pre-main fader(s). Use them to insert, for example, 

a dynamics processor or graphic equalizer. Please also note the information on 

insert points in chapter 5.3.

Fig. 5.2: Subgroup outputs

SUB OUTPUTS
The subgroup outputs are unbalanced and provide the mix of those channels 

assigned to each subgroup with the SUB switch (QX2442USB: switches 1-2 or 

3-4) next to the channel faders. Thus, you can, for example, route a subgroup 

to a second console or use the output as a recording output in parallel to the 

main outputs. In this way, you can record several tracks simultaneously. With an 

8-track recorder, use Y cables and wire the inputs of your machine so that you 

have 2 x 4 tracks available (e.g. channel 1 to track 1 and 2, etc.). In the first pass, 

you can record the tracks 1, 3, 5 and 7, in the second the tracks 2, 4, 6 and 8.
The XENYX QX2442USB already has subgroup outputs wired in parallel 

(1-5, 2-6, etc.).

Fig. 5.3: Insert points

Insert points are very useful to process channel signals with dynamic processors 

or equalizers. Unlike reverb or other effects devices, whose signals are usually 

added to the dry signal, dynamic processors are most effective on the complete 

signal. In this case, aux send paths are a less-than-perfect solution. It is better 

to interrupt the signal path and insert a dynamic processor and/or equalizer. 

After processing, the signal is routed back to the console at precisely the same 

point it left. However, the channel signal path is interrupted only if a plug is 

inserted into the corresponding jack (stereo phone plug: tip = signal output; 

ring = return input). All mono input channels are equipped with inserts. They are 

pre-fader, pre-EQ and pre-aux send. Inserts can also be used as pre-EQ direct 

outputs, without interrupting the signal path. To this end, you will need a 

cable fitted with mono phone plugs on the tape machine or effect device end, 

and a bridged stereo phone plug on the console side (tip and ring connected).

Fig. 5.4: Direct outputs 

DIRECT OUTPUTS
The direct outputs of the QX2442USB (1 each per mono input channel) are 

ideal for recording if several tracks are to be recorded simultaneously. These 

unbalanced phone jacks are post-EQ, post-mute and post-fader.

Fig. 5.5: USB input/output

The XENYX mixer line has built-in USB connectivity, allowing stereo signals to 

be sent to and from the mixer and a computer. The audio sent from the mixer to 

a computer is identical to the MAIN MIX. Audio being sent to the mixer from a 

computer can be routed to the main mix with the 2-TR/USB TO MAIN button. 
Connect the USB type B plug into the USB jack on the mixer, and the other end 

into a free USB port on your computer. There are no required drivers, but we 

recommend that PC users install the ASIO driver which can be downloaded from 

behringer.com.
Note - the mixer cannot be bus-powered via USB. Always use the internal power 

supply to power the unit.
