AUX SEND 1-2 to FW 13-14
Engage this button in the aux master section, and 
a copy of aux send 1 and 2 outputs can be sent via 
FireWire to your computer. This makes it possible to set 
up a software effects processor thus-wisely:
• 
Set aux send 1 and/or 2 in post mode, by  
pressing the post switch in the aux master  
section.
• 
With "aux send 1-2 to FW 13-14" engaged, aux 
send 1-2  are available for your computer via 
FireWire signals 13 and 14. (Mixer channels  
13-14 are no longer available to send via 
FireWire.)
• 
Pass aux 1 or 2 through your audio production 
software running effects plugins.
• 
Return the processed output to mixer channels 
15 and 16 (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 
plug-ins are combined back into the stereo 
stream coming back to the mixer. Again, 
performance will vary based on system  
hardware.
ASSIGN to FW 15-16 
Engage this button near the main fader, and the main 
mix can be sent to your computer via Firewire. The 
FireWire 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 signal 15, and the right on signal 16. 
(When this button is engaged, mixer channels 15-16 are 
not available to send via FireWire.)

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 or line signal, sending the 
result to 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.
