Main Mix
XLR MAIN OUTPUTS
The male XLR output connectors provide a balanced 
line-level signal that represents the end of the mixer 
chain, where your fully mixed stereo main mix signals 
enter the real world. Connect these outputs to the 
inputs of your main power amplifi ers, powered  
speakers, or serial effects processor (or a graphic  
equalizer or compressor/limiter). The output provides a 
fully balanced signal playing the same program material 
as the 1/4" TRS main outs.
MAIN OUTPUT LEVEL (+4 dB/MIC)
When this recessed switch is out (+4 dB), the XLR 
main outputs provide a "+4 dBu" line-level signal. You 
can then connect these outputs to the line-level inputs 
of power amplifi ers, powered loudspeakers, or serial 
processors. In a studio setting, you could connect the 
main mix to the inputs of a professional stereo recorder.
When the switch is pushed in (mic), the XLR main 
outputs are attenuated to microphone level. You can 
then connect these outputs safely to the microphone  
inputs of another mixer, providing a submix for  
 
keyboards or drums, for example, in a live sound  
application. The main outputs can then be plugged  
directly into a stage snake, and appear back at the front 
of house console like any other microphone level source.
When mic is engaged, you can safely plug the XLR 
main output into another mixer's microphone input, 
even if it provides 48 V phantom power.
The switch is recessed, to reduce the chance of    
accidently turning it on or off when plugging things in.
1/4" TRS MAIN OUTPUTS 
These 1/4" TRS output connectors provide the 
balanced or unbalanced line-level output of the main 
mix. This is the same signal that appears at the XLR 
main outputs, except it is not affected by the main 
output level switch.
MAIN MIX FADER 
This is the main stereo fader that adjusts the level of 
the XLR and 1/4" main outputs, and the tape output. It 
does not affect the FireWire output of the main mix.
If the gain of each channel has been set up correctly 
for all your microphones, line-level sources, guitars, and 
so on, then these channels can be added to the main 
mix by careful adjustment of the channel faders. The 
main mix fader is then used to turn the complete main 
mix level up and down.
MAIN MIX and FIREWIRE 
The main mix can be sent to your computer via two 
dedicated Firewire signals. The output is not affected by 
the main mix fader, allowing you to record the main mix 
of live performances. The left main mix will appear on 
FireWire output channel 15, and the right on  
channel 16. 
In addition to recording the main mix using FireWire, 
you can record individual channels using FireWire, for 
studio mixing at a later date. See page 15.
TAPE OUT
This RCA unbalanced output is a copy of the main mix 
(post fader). You can use it to record the main mix on 
an analog tape deck for example.
