7.0 INTERNAL CONTROLS
On the main PCB inside the unit there are several adjust controls :
16 BINAURAL ROUTING jumpers
In case of binaural use of the PS 630, these jumpers
determine – for each channel separately - the routing
of the intercom audio to the headset.
17 CALL RECEIVE jumpers
For each channel separately, these jumpers enable
or disable the reception of a CALL signal when the
channel is switched off.
18 PGM ROUTING jumpers
With these two jumpers one determines whether the
PGM (program audio) listen level is also controlled by
the Master Volume knob (see #4) and – in case of
binaural use of the PS 630 - the routing of the PGM
signal to the headset.
PGM routing jumpers:
