ON switch
This switch turns the stereo module on/off. When the switch is pressed the
stereo module is on. Be sure to turn off input modules that are not in use.
Even when a module is off, the SIGNAL and PEAK indicators will light if a
signal is being input. You can also use the PFL switch to monitor the signal
even if a module is off.

PFL switch
PFL is an acronym for Pre-Fader Listen. This switch allows you to monitor
the signal of the stereo module regardless of the fader position, the settings
of the ON switch, the group assign switches, or the AUX settings. As the
name suggests, the signal is taken pre-fader (post EQ). You may listen to an
individual module, or to two or more modules simultaneously.
