VOICE CANCELLER
Here, you have a filter circuitry that lets you almost entirely remove the 
vocal portion of a recording. The filter is constructed in such a way that voice 
frequencies are targeted without majorly affecting the rest of the signal. 
Additionally, the filter seizes only the middle of the stereo image, exactly there 
where the vocals are typically located.
Possible applications for the Voice Canceller are obvious: you can very simply 
stage background music for Karaoke events. Of course, you can also do this at 
home or at your rehearsal room before you hit the stage. Singers with their own 
band can practice singing difficult parts using a complete playback from a tape 
player or a CD, thus minimizing rehearsal time.
STANDBY
If the STANDBY switch is pressed, all input channels with a mic connector 
(XLR connector) are muted. During breaks or stage conversion, you can prevent 
noise from entering the sound system via the microphones. Such noise can in the 
worst-case scenario even irreparably damage loudspeaker membranes. The cool 
thing about this is that the main mix faders can remain open, so that you can play 
music from a CD at the same time. Similarly, the faders for the muted channels 
can also remain in their position.
To bring in other sound sources, you can use the 2-track inputs, stereo input 
channels 9 to 12 and the aux return inputs.
2-TRACK MUTE
Using this switch, the input signal from the 2-track inputs is muted.
2-TRACK RET(URN)
This stereo fader assigns the input signal from the 2-track inputs into the 
main mix.

2-TRACK INPUT
The 2-TRACK INPUT RCA connectors are provided for connecting a 2-track 
machine (e.g. DAT recorder) or also a CD player. They can also be used as stereo 
line input. Alternatively, the output signal of a second EURORACK or BEHRINGER 
ULTRALINK PRO MX882 can also be connected. If you connect a hi-fi amplifier 
with a source selection switch to the 2-TRACK INPUT, you can easily switch 
between additional sources (e.g. cassette recorder, MD player, sound card etc.).
Using the voice canceller function, you can process all signals being brought into 
your mixing console via these connectors.
2-TRACK OUTPUT
These connectors are wired pre graphic EQ and pre XPQ surround function. 
They carry the main mix signal (unbalanced), effects mix included. Connect the 
2-TRACK OUTPUT to the inputs of your recording device. If you wish to use your 
mixer solely for recording purposes, the main outputs are also an alternative.

The MAIN outputs carry the MAIN MIX signal and are on balanced XLR connectors 
with a nominal level of +4 dBu. Depending on how you wish to use your mixer 
and which gear you own, you can connect the following equipment:
Live PA systems:
A stereo dynamics processor (optional), stereo equalizer (optional) and the stereo 
power amplifier for full-range loud-speakers with passive crossovers.
If you wish to use multi-way loudspeaker systems without an integrated 
crossover, you have to use an active crossover and several power amplifiers. 
Often, limiters are already built into active crossovers (e.g. BEHRINGER SUPER-X 
PRO CX2310 and ULTRADRIVE PRO DCX2496). Active crossovers are implemented 
directly before the power amplifier, and they divide the frequency range into 
several segments that are first amplified in the amplifiers and then passed onto 
the corresponding loudspeakers.
Recording:
For mastering, using a stereo compressor such as the COMPOSER PRO-XL 
MDX2600 can be recommended. Use it to custom-tailor the dynamic 
characteristics of your signal to the dynamic range of the recording equipment 
you are using. The signal is in this case passed on from the compressor into 
the recorder.
