JBL CSM 14 Operation Manual - 3.2 Input Routing
21
3.2 Input Routing
CSM 28 include a default routing of input
channels 1-4 to output 1 and input channels 5-8
to output 2. The user may also take any input
and have it routed to both outputs by selecting
the appropriate switch. For example, if you set
switch 1 to ON, it will be routed to both OUT1,
and OUT2.
3.3 Phantom Power
Phantom power (27V) can be applied to all mic inputs by turning on the Phantom
Power switch on CSM 14 units or DIP switch #6 on CSM 28 units.
3.4 VOX Function
Voice activated ducking is available
on input channel 1 of CSM 14 units
and for both input channels 1 and 5 of
CSM 28, The audio input level required
to activate ducking is set using the trim
pot on the rear panel. Adjusting in the
counter-clockwise direction will reduce
that level while the full clockwise
setting will disable the VOX function.
3.5 Priority Muting
With CSM 14 Input Channel 1 may be used as a priority channel, muting all other
channels when pin 4 and pin 5 are shorted using a switch closure.
CSM 28 units let Input Ch1 operate with priority over all inputs into OUT 1. Ch1 will
have priority over both OUT 1 and OUT 2 if the routing DIP switch #1 is set to ON.
Ch5, however, cannot have priority over the OUT 1 inputs.
3.6 Remote Volume Control
Remote volume control can be implemented using a CSR-V controller connected via
an ethernet cable to the RJ45 connector on the back panel. For CSM 28 units, there
are two connectors, one for each output.
