10 EURORACK UB1222FX-PRO User Manual
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 dicult 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- amplier
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), eects 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.

MAIN OUT
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 amplier 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 ampliers.
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 amplier, and they divide the frequency range into
several segments that are rst amplied in the ampliers 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.
