GENERAL DESCRIPTION

The PS 6379 Mk2 is a master loudspeaker station with 6 intercom channels and a built-in
power supply, offering full duplex communication with analog remote stations.
The unit incorporates a loudspeaker, a gooseneck microphone and an XLR-4 headset con-
nector.
As an option, an XLR-6 headset connector can be fitted for binaural (split ear) use of the
headset.
By setting internally mounted jumpers, each of the 6 channels can be assigned to either
the left or the right headset can, or to both headset cans.
If the gooseneck microphone is active the loudspeaker is automatically attenuated.
The degree of attenuation can be adjusted by a trimmer at the front panel. If a headset is
connected, both gooseneck microphone and speaker are switched off automatically.
The loudspeaker can be switched on again by pushing the Speaker on/off button.
The PS 6379 Mk2 has newly designed mic input circuits with a proprietary limiter allowing
to speak close and/or loud into the headset or gooseneck microphone without giving rise
to overload and distortion
The unique CALL system provides both a flashing red LED and a very distinctive sound
signal (buzzer). The volume of the buzzer can be adjusted by a trimmer on the front panel.
