Assign switches (1-2, 3-4, ST)
These switches assign the signal of the input module to the group outputs
and the ST output. The PAN control located below adjusts the stereo posi-
tion of the signal between the odd (ODD) group and left (L) outputs and
the even (EVEN) group and right (R) outputs.
0
PAN control
This knob adjusts the stereo position of the signal between the stereo L and
R, and between the odd/even groups. For example if this knob is turned all
the way to the left, the signal will be sent only to the L and odd (ODD) groups
whose assign switches are pressed. If it is turned all the way to the right, the
signal will be sent only to the R and even (EVEN) groups. If the knob is set
to the center position, the same amount of signal will be sent to the stereo
L and R, and the odd/even groups.
A
ON switch
This switch turns the input module on/off. When the switch is pressed in
the input 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 sig-
nal even if a module is off.
B
PFL switch
PFL is an acronym for Pre-Fader Listen. This switch allows you to monitor
the signal of the input 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. The PFL
indicator located at the top of the STEREO module will light when a PFL
switch is on.
C
Fader
This adjusts the signal level that is sent to the various outputs. Faders are
used individually or in conjunction with the faders of the other input mod-
ules to create the desired mix balance. A position at the zero (0) marking is
the nominal level. Raising the fader above 0 provides up to 10dB of gain.
