MX12/6, 20/6 — Owner’s Manual
yEFFECT Control

Controls the level of the signal sent from each channel to the EFFECT bus.

This control is located after the channel fader so its level will also be affected by the channel fader

setting.

When a stereo channel is used, L and R channel signals are combined and sent to the EFFECT bus.

uPAN Control (MX12/6:CH1-8, MX20/6:CH1-16)BAL Control (MX12/6:CH9-12, MX20/6:CH17-20)

The PAN control knobs set the position within the stereo field of each signal that is sent to the GROUP

bus 1-2, GROUP bus 3-4 and STEREO bus L-R.

The BAL control knobs set the balance between left and right channels and assigns the signals that are

received at INPUT L (MX12/6:CH9, 11, MX20/6:CH17, 19) to GROUP buses 1/3 or STEREO bus L,

and the signals received at INPUT R (MX12/6:CH10, 12, MX20/6:CH18, 20) to GROUP buses 2/4 or

STEREO bus R.
