21 ALL BUZZERS MUTE button

With this button the buzzers of the connected

stations and of the PS 6379 can be muted.

The buzzers remain being muted until the ALL

BUZZER MUTE button is switched off again (the

buzzer mute status is abolished).

22 SET UP LOCK

The AUX levels, the IFB AUX levels and the setting

of the buzzer mutes can be locked by pushing a

small pin into the SETUP lock. It is unlocked by

pushing the lock again.

Adjusting the light intensity of the LEDs in the

Mic Mute-, Buzzer Mute-, Aux- and IFB buttons:

Push and hold the SETUP lock, turn the AUX LEVEL

/ DIM FACTOR knob (#18) clockwise to increase or

counter-clockwise to decrease the light intensity.

23 SYSTEM LINK LED (per channel)

This LED illuminates if a channel of another ASL

Intercom System has been connected to the

corresponding channel of the PS 6379, through its

“System Link” connector (see #32). The line

impedance is now provided by the other intercom

system and the internal line impedance for that

channel is switched off.

A Mic Mute signal sent from the other system is also

received by the user stations on the corresponding

channel of the PS 6379. To achieve that Mic Mute

signals sent from the other system are not received

by the user stations connected to the PS 6379, the

position of dipswitch no 1 in dipswitch block E has to

be changed (see section 11.0). A Mic Mute signal

sent from the PS 6379 is always only received by its

own user stations (it does not mute the microphones

of the user stations of the other system)

Buzzer Mute signals are not going from the other

Intercom system to the PS 6379, nor in the opposite

direction.

24 ON/OVERLOAD LEDs (per channel)

These LEDs indicate the status of each channel.

A LED is lit green when 30 V DC line power is

supplied to the corresponding channel and flashes

red when that channel is reaching an overload.

In this case that channel is still functioning but will

shut off as soon as more units are added.

The LED is constantly lit red when too many units

have been connected to the corresponding channel

or if there is a short circuit on that channel. When all

LEDs are lit red and one or more channels are

switched off (see #1) a master overload occurred.

In this case the channel with the lowest load switches

off. If that is not sufficient the next channel switches

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 also lights up red - for a few

seconds - every time mains power is switched on.

25 MIC MUTE button (per channel)

With this push button the TALK button on stations of

which the corresponding channel is connected to the

corresponding intercom line (party line) coming from

the PS 6379, can be remotely disabled (the

microphone signal of these stations is no longer sent

to that party line). On each of these stations the

disabled TALK button can be enabled again by

pushing it.

26 BUZZER MUTE button (per channel)

With these push buttons the buzzers of all stations

connected to that channel can be muted. The

buzzers remain being muted until the BUZZER

MUTE button is switched off again (the buzzer Mute

status is abolished).

27 IFB button (per channel)

With these push button a channel can be put into IFB

Mode. The channel is now a so-called IFB channel,

used for one way communication from i.e. a

director/producer to a talent in a broadcast

environment. After having pushed an IFB button the

AUX button (#17) of the corresponding channel

automatically lights up indicating that the signal

coming from IFB auxiliary input #36 is routed to that

IFB channel. If no IFB-Auxiliary signal is needed,

push the AUX button to switch off. For IFB channel

properties and applications, see section 12.1.
