AUX SEND 1-2
A direct copy of the aux send 1 and 2 outputs can 
be sent via FireWire to your computer. This makes it  
possible to use a software effects processor instead of an 
expensive external processor.
To setup a software effects processor:
• 
Set up an aux send in post mode, by pressing 
the post switch in the aux master section.
• 
Aux send FireWire outputs 13 and 14 are  
available for your computer.
• 
Pass this through your audio production  
software running effects plugins.
• 
Return the processed output to mixer channels 
11 and 12 (input switch set to FW 1-2).
• 
Alternatively bring the processed sounds into 
the control room (engage FW 1-2) and add it to 
the main mix (engage assign to main mix).
• 
You can even use the computer as two separate 
independent mono in, stereo out processors. 
Have aux 1 go into one plugin, and aux 2 go into 
a different one. The stereo outputs of both 
plugins are combined back into the stereo 
stream coming back to the mixer. Again, 
performance will vary based on system  
hardware.
MAIN MIX
The left and right main mix is always available on 
FireWire channels 15 and 16 to send to your computer. 
For example, you can record the live performance main 
mix onto your computer. The output level to your  
computer is not affected by the main mix level control.
Modifi cations:
The following FireWire modifi cations can be done by 
an authorized service center. Authorized service centers 
may be found online at:

Please contact our technical support department if you 
are having trouble fi nding an authorized service center 
in your area.
Post-Insert FireWire Sends 
The pre-EQ channel FireWire sends are pre-insert, 
but the circuit boards can be modifi ed so that they are 
post-insert instead. This allows for the use of an  
external processor on the mic signal, sending the result 
to the FireWire, while still pre-EQ.
Post-Fader FireWire Sends 
The post-EQ channel FireWire sends are pre-fader, 
but the circuit boards can be modifi ed so that they are 
post-fader instead. This allows the channel fader to  
control the level of the FireWire sends from each  
channel.
