6.0 FRONT PANEL CONTROLS & CONNECTOR (continued)
22 SET UP LOCK
The setup of the AUX, IFB and Buzzer mutes can be
locked by pushing a small pin into the SETUP lock. It will
be unlocked by pushing it again. When pushing and
holding the set up lock, the light intensity of the LEDs of the
MIC MUTE-, BUZZER MUTE-, AUX- and IFB LEDs, can be
increased by turning the AUX level / IFB Dim knob. In
"Near Station" mode (see section 9.0 Modes) one can
adjust the dim factor per channel by pushing and holding
the set up lock as well as the TALK button of the required
channel and turning the AUX level / IFB Dim knob. The dim
factor will be shown on the Aux level / IFB dim LED bar.
23 SYSTEM LINK LEDs (per channel)
These LEDs illuminate if another ASL Intercom System has
been connected to the PS 6379 through the "System Link"
connector at the corresponding channel. The Line
Impedance is now provided by the other Intercom system
and the internal line impedance for that channel is switched
off. The Buzzer mute function on the system-linked
channels can now only be controlled by the connected
system, while the Buzzer Mute on the channels which are
not in System link will still be controlled by the PS 6379.
The Mic Mute signals given by the other Intercom system
are also sent to the user stations which are connected to
the PS 6379 on the channel which is in system link. If a Mic
Mute is given by the PS 6379, it is only sent to its own
channels and does not mute the microphones of the other
Intercom System.
24 ON / OVERLOAD LEDs (per channel)
These LEDs will indicate the status of each channel.
The LEDs will illuminate green if power is supplied by the
internal power supply.
The LEDs will flash red, when the corresponding channel is
reaching an overload. In this case the channel is still
functioning but will shut off, if further units are added. If all
LEDs are flashing the complete system is close to going
into overload and should additional units be added, the
channel will shut down.
The LEDs will go constantly red, when too many units have
been connected or if there is a short circuit on the
corresponding channel. If all LEDs are lit red and one or
more channels are switched off, a master overload
occurred. In this case the channel with the lowest load will
switch off. If that is not sufficient the next channel will

switch off - and so on.
The circuit-breaker resets automatically 3 seconds after the
cause of the overload has been removed, and restores line
power automatically.
The LED will also light up red for a few seconds every time
mains power is switched on.
25 MIC MUTE (per channel)
With these pushbuttons the microphones of the connected
stations can be switched off for each channel separately.
Each user station can activate its microphone again by
pushing the TALK button.
26 BUZZER MUTE (per channel)
With these pushbuttons the buzzers of all stations
connected to that channel can be muted, until the BUZZER
MUTE button is switched off again.
27 IFB (per channel)
With these pushbuttons a channel can be put into IFB
Mode. This is used for monitoring purposes and one
way communication from i.e. a director or producer to a
talent. If a channel is put into IFB mode, the AUX button of
that channel will switch on automatically and the auxiliary
signal of the IFB auxiliary input will be routed to that
channel. If no IFB-Auxiliary is needed, it can be switched
off by switching off the aux button of that channel. The
AUX-input can also be routed to an IFB channel by
switching the corresponding dip switch (IFB or AUX input
for IFB) to 'on' (see section 8.0 Internal controls / Dip
switches).
The TALK button of an IFB channel will be momentary and
not latching and must be pressed while talking. When
pressing the TALK button of an IFB channel, the aux
volume will be dimmed automatically by 50 %. This dim
factor can be adjusted (see point 17 AUX Level / IFB DIM).
The TALK buttons of the intercom channels will switch off
for as long as the IFB TALK button is pushed. This can be
changed by setting the corresponding internal dip switch
(IFB and TALK) to 'on' (see section 8.0 Internal controls /
Dip switches).
