Channel Assignment – Mono input channels are permanently assigned to USB/SD
outputs. In addition to these, the CQ-12T has 3 assignable stereo outputs and the
CQ-18T and CQ-20B each have 4 assignable stereo outputs. These allow recording
and playback of stereo line inputs, FX units, Main LR output or outputs 1-6.
The last stereo pair is set to Main LR by default and as well as being sent to
multitrack outputs, is used for stereo recording to USB-A or when the USB-B
Stream Mode is set to Stereo.
