Channel Controls
The 10 vertical channel strips look very similar, and
have a only few differences between them. Each chan-
nel works independently, and just controls the signals
plugged into the inputs directly above it.

Mono Channels 1 to 8
•
Channels 1 to 8 are mono channels, and their
controls affect either the mono mic input or the
mono line-level input.
•
Channels 1 to 6 each have an internal signal in-
line compressor circuit with adjustable thresh-
old.
•
Channels 7 and 8 each have a hi-z switch, so
you can connect guitars directly, without the
need for a DI box.
•
The 3-band EQ has shelving high, shelving
low, and peaking mid EQ with adjustable mid
frequency.

Stereo Channels 9/10 and 11/12
•
Channels 9/10 and 11/12 are stereo channels,
and their controls affect signals coming into the
stereo line-level inputs
•
The stereo channel EQ is a 4-band design with
1
shelving high, shelving low, and peaking lo-mid

and peaking hi-mid.
