8.0 FRONT PANEL CONTROLS & CONNECTOR
1 LISTEN LEVEL control knobs
These knobs preset the listen level for each
channel separately. Turning a knob fully counter-
clockwise switches off the referring channel. The
„Channel On‟ LED extinguishes. For receiving a
Call signal whilst the channel is switched off, see
section 11.0 and the dip switches in block B
2 TALK buttons
These buttons allow talking to each channel
separately or to some or all channels
simultaneously. When a TALK button is switched
on, its large green LED is lit.
By pushing and holding the TALK button of a so-
called IFB channel or a Paging channel, the
TALK buttons of the Intercom channels switch
automatically off (for further explanation see
sections 12.1 and 12.2). To talk to an IFB or
Paging channel and additionally to a intercom
channel, one should also push and hold the TALK
button of that intercom channel. To achieve that
one can talk to an IFB or a Paging channel and
automatically to all intercom channels of which the
TALK buttons are enabled (the corresponding
Talk LEDs are lit), the position of certain dip
switches has to be changed. See section 11.0, dip
switch No 3 and No 4 in block A.
Momentary switching:
If a TALK button is pushed and held, the microphone
signal is sent to the referring intercom channel until
the button is released.
Latched switching:
If a TALK button is pushed shortly, it is electronically
latched and the microphone signal is sent to the
referring intercom channel. If pushed again, the
TALK button switches off. The latch function can be
disabled by changing the position of certain dip
switches (see section 11.0, the dip switches in block
D). The TALK button is then “momentary only”.
Mic Mute when latched on:
After on an intercom channel a so-called Mic Mute
signal has been received from a PRO Series
master station or power supply, the connection
between microphone and the referring intercom
channel is interrupted. By pushing the TALK
button, the connection is restored again.
3 CALL buttons
These buttons activate the call system, for each
channel separately. By a momentary push a
visual CALL signal is sent to all stations
connected to the referring intercom channel and
the call LEDs start flashing. By holding the CALL
buttons for 2 seconds the buzzer are activated,
provided there is no buzzer mute on that channel.
After the CALL button is released the LEDs
continue to flash for a further 2 seconds.
4 TALK TO ALL button
When this (momentary only) button is pushed and
held, one may talk to all intercom channels
simultaneously. The green TALK LEDs of all
channels light up (except for the Talk LEDs of the
IFB or PAGING channels ). To also include the
IFB and PAGING channels, the position of certain
dip switches have to be changed (see section
11.0, dip switch No 4 and No 5 in block A).
5 CALL TO ALL button
When this button is pushed shortly a visual Call
signal is sent to all channels simultaneously and
all Call LEDs of the PS 6379 and of all connected
stations start flashing. When holding the CALL TO
ALL button for 2 seconds the buzzer is activated,
should no buzzer mute be activated for that
channel. After the CALL TO ALL button is
released the LEDs continue to flash for further 2
seconds.
6 MASTER VOLUME knob
This knob adjusts the listen volume of the speaker
or headset. The position of jumpers (see #44)
determine whether the Master Volume knob also
controls the PGM (program audio) listen level.
