SPEAKER ATTENUATOR trimmer
This trimmer adjusts the extent to which the
loudspeaker is automatically dimmed when the
gooseneck microphone is switched on. It prevents
unit feedback if side tone rejection is not sufficient.
It also minimizes system feedback or a 'hollow'
sound when the gooseneck microphones of other
speaker stations (on one or several of the connected
party lines) are switched on as well.
Adjustment procedure :
o
make sure that there is no headset
connected
o
switch off all TALK buttons of the PS 430.
o
inject an audio signal on one of the intercom
channels via the aux input of a Pro Series
master station or separate power supply
o
turn up the listen volume of the PS 430
(channel – and master volume).
o
activate the gooseneck microphone (push
the TALK button of the selected channel)
o
adjust the desired degree of speaker
attenuation (turning the trimmer counter-
clockwise increases the attenuation)
