INPUT (LINE or FW 1-2) Channel 7 and 8 can either be fed from the 1/4" stereo line-level inputs, or by FireWire outputs 1 and 2 from your computer. This switch lets you choose which to use. Either way, channels 7 and 8 receive line-level analog audio signals just prior to the gain control, so channel setup, gain adjustment and EQ adjustment are the same for line or FireWire. CONTROL ROOM FW 1-2 If this is engaged, you can listen to FireWire 1 and 2 playback from your computer in the control room and headphones. This can also be added to the main mix if control room assign to main mix is engaged. See below. ASSIGN TO FW 7-8 This switch allows you to assign the left and right main mix to FireWire outputs 7 and 8. 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. Note: If this switch is engaged, then there is no FireWire output to your computer directly from mixer channels 7 and 8. The main mix goes to your computer instead. ASSIGN TO MAIN MIX Engage the control room FW 1-2 switch and the assign to main mix switch to play two tracks directly from your computer through the control room/phones source matrix and into the main mix. This is great for listening to iTunes® or other pre-recorded material from your computer. AUX SEND 1-2 to FW 5-6 This switch allows you to send a direct copy of the aux send 1 and 2 outputs 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 • Engage this switch, and aux send FireWire outputs 5 and 6 will be available for your computer. • Pass this through your audio production software running effects plug-ins. • Return the processed output to mixer channels 7 and 8 (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 plug-in, 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. Note: If this switch is selected, then there is no FireWire output to your computer directly from mixer channels 5 and 6. Aux sends 1 and 2 go to your computer instead. 16 Onyx 820i
