  • Page 5: General Description

    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.
  • Page 6 IFB function: Two channels of the PS 6379 Mk2 can be programmed to be so-called IFB (‘Interrupt Fold- back’) channels, used for one way communication from i.e. a director/producer to a “tal- ent” (e.g. a reporter or show presenter) in a broadcast environment. (see section 10.0) The talent has a headphone or an earpiece, connected to an analog IFB receiver or stand- ard analog beltpack.

  • Page 8: Mains Power & Safety Earth

    WARNING: This appliance must be earthed! Connecting to mains power: The PS 6379 Mk2 may be connected to a mains power outlet which provides 100 – 240 V AC, 50-60 Hz, 200 watts. The outlet should have a clean earth. Avoid using mains power outlets which also power dimmer controlled lighting equipment.

    To limit the inrush current after the PS 6379 Mk2 has been switched on, 30 V DC line power is provided to the intercom channels, one after the other. If a channel is found to have too many stations being connected or in case of short circuit, a circuit breaker im- mediately shuts off that channel from 30V DC line power.
  • Page 10 Momentary switching: If a TALK button is pushed and held, the microphone signal is sent to the referring inter- com channel until the button is released. Latched switching: If a TALK button is pushed shortly, it is electronically latched and the microphone signal is sent to the referring intercom channel.
  • Page 11 • push the TALK button of the channel to be null adjusted • slowly turn up the listen volume of the PS 6379 Mk2 (channel + master volume) • speak into the gooseneck microphone • adjust the speaker listen level to a minimum by turning the null adjust trimmers counter clockwise (first the LOW trimmer and then the HIGH trimmer;...

  • Page 13 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...
  • Page 14 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 sta- tions 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.
  • Page 15 By turning this knob one adjusts the listen volume of the PGM input. The signal of the PGM input can only be heard on the speaker and/or headset of the PS 6379 Mk2 and does not appear on the intercom lines.
  • Page 16 ALL MICS MUTE button By pushing this button the TALK buttons of the PS 6379 MK2 and the TALK buttons of the connected remote stations are disabled (if they were previously enabled). After the ALL MICS MUTE button is being pushed, it is lit for a few seconds.
  • Page 17 As soon as more than the allowed maximum allowed user stations are connected to the PS 6379 Mk2 (the current from the built-in PSU is in danger to exceed 5A) the red Overload LED is lit and a circuit breaker disconnects the line power from all channels. The circuit- breaker resets (restores line power) automatically 3 seconds after the cause of the over- load has been removed.
  • Page 18 The speaker can be enabled again by pushing the SPEAKER on/off button (#18). The PS 6379 Mk2 can optionally be equipped with an XLR-6 headset connector for binau- ral use of the headset. Internal jumpers determine - for each channel separately - the routing of the audio to the headset cans: either to the left can, or to the right can or to both cans.

    10.0 IFB FUNCTION With the IFB Mode switches #36 on the rear panel, channel E respectively channel F can be put into IFB Mode, which is indicated on the front panel by lit IFB Mode LED indicators. 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: If the director pushes the TALK button of an IFB channel, the talent hears the producer but may also listen to an auxiliary signal.

    ASL reserves the right to alter specifications without prior notice 13.0 PARTY LINE, TECHNICAL CONCEPT User stations and power supplies in an ASL intercom system are connected via one or several 'party lines'. A party line offers two-way (‘full duplex’) communication and consists of standard micro- phone (multi-pair) cable.
  • Page 29 type. Audio and Call signals are on pin 3, DC power is on pin 2 and pin 1 is connected to the shield of the cable which functions as the common return for audio and power. The audio signal is transferred in an unbalanced way (see ‘Party Line, Technical Concept’). To avoid earth loops (hum), the possible effect of electromagnetic fields and to minimize power loss, certain rules must be obeyed when installing the cabling of an intercom sys- tem:...
  • Page 30 When two (multi-channel) units in a network are connected by more than one cable, make sure that these cables are parallel to each other over the whole distance between those units. When using multi-pair cable, parallelism is ensured in the best possible way. Avoid closed loops Always avoid that intercom cables are making a closed loop.
