MONI (monitor) control
This knob controls the level of the signal that is sent from each
channel to the MONI bus.
Since this control is placed before the channel fader, it controls
the level independently from the channel fader setting.

EFFECT control
This knob controls the level of the signal that is sent from each
channel to the EFFECT bus.
Since this control is placed after the channel fader, the signal
level will be affected by the channel fader setting.
