9 AUX Volume knob
By turning this knob one adjusts the level of the
auxiliary signal as sent to the corresponding
channel. The AUX signal may originate from either
AUX input 1, AUX input 2 or AUX input 3 (see
AUX inputs #34 and AUX select switches #35)
10 SYSTEM LINK LED
This yellow LED illuminates if a channel of another
ASL Intercom System has been connected to the
PS 6379 Mk2 through the "System Link"
connector (#33) of the corresponding channel. The
"other system" channel is now the MASTER
channel and the 'linked' PS 6379 Mk2 channel the
SLAVE channel (The line impedance is now
provided by the MASTER channel and the line
impedance of the SLAVE channel is switched off).
One can talk, listen and call to and from all user
stations which are connected to the MASTER
channel and to the SLAVE channel.
A Mic Mute signal sent from the MASTER
channel to the SLAVE channel is also received by
the user stations on that channel. But a Mic Mute
signal sent from the PS 6379 Mk2 is only received
by the user stations on its own channels (it does
not mute the microphones of the user stations on
the MASTER channel)
A Buzzer Mute signal on the MASTER channel is
received by the user stations on that channel and
by the user stations on the SLAVE channel.
A SLAVE channel is not able to generate a
Buzzer Mute signal (the Buzzer Mute button of the
SLAVE channel is disabled).

11 ON/OVERLOAD LED
This LED is lit green when 30 V DC line power is
supplied to the corresponding channel.
The LED is lit red when too many user stations
have been connected to the corresponding
channel or if there is a short circuit on that
channel. A circuit breaker immediately disconnects
the line power from that channel and resets
(restores line power) automatically within 2
seconds after the cause of the overload has been
removed.
12 IFB MODE LED indicator (for channels E
and F only)
This yellow LED is lit if the channel is put into IFB
mode, see section 10.0
13 TALK TO ALL button
By pushing and holding this (momentary only)
button one may talk to all intercom channels
simultaneously. The green LEDs in the TALK
buttons of all channels light up, except for the
LEDs in the TALK buttons of the channels in IFB
Mode. To also include the TALK buttons of the
channels in IFB Mode, the position of certain DIP
switches have to be changed (see section 11.0,
DIP switch C).
14 CALL TO TALK button
By shortly pushing this (momentary only) button a
visual Call signal is simultaneously sent to all
channels of which the TALK buttons are switched
on. All corresponding Call LEDs of the PS 6379
Mk2 (except the ones of the channels in IFB
Mode) and of all connected stations start flashing.
When holding the CALL TO TALK button pushed
for 2 seconds the buzzer is activated, should no
buzzer mute be activated for that
the CALL TO TALK button is released the LEDs
continue to flash for a further 2 seconds.
