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 channel. After the CALL TO TALK
button is released the LEDs continue to flash
for a further 2 seconds.
