2.0 GENERAL DESCRIPTION

The PS 6379 is designed to be a six channel loudspeaker master unit in an ASL Intercom system and can be used in portable as well as fixed applications. It incorporates a power supply, auxiliary inputs, program input, headset connector, loudspeaker and a gooseneck microphone, stage announce output, IFB Mode, Paging Mode, Near Station Mode and Extended Mode (see section 9 for further explanation of each Mode) and provides full duplex communications within an ASL intercom system. The PS 6379 RM model has a small built-in electret microphone. The power supply supplies power to a max. of 60 Beltpacks or 30 Speaker Stations.

Each channel has a Volume (listen level) control, a Talk and Call button with LED indicators and a two-stage sidetone trimmer. A master volume controls the total speaker/headset volume.

The unit is equipped with a limiter for the gooseneck microphone, allowing the user to speak close into the microphone without giving rise to overload and distortion. Loudspeaker dimming is automatic when the microphone is active. Private conversation may be carried out via the headset connector with a headset or telephone handset. When a headset is connected, both gooseneck microphone and speaker are switched of automatically. The speaker can be then switch on again with the Speaker on/off button.

As an option, a XLR-6 headset connector can be fitted for binaural use of the headset. By setting internally mounted jumpers, each of the 6 channels can be assigned to

3.0 UNPACKING

The shipping carton contains the parts listed below: * The PS 6379 * power cable * User manual * 2 x Fuses * 19” rackmount flares If any are missing, contact your dealer.

ASL has taken great care to ensure this product reaches you in flawless condition.

4.0 INSTALLATION

This PS 6379 will form part of an existing or new intercom system, and connection to it is straightforward.

Adequate ventilation must be provided by allowing sufficient space around the sides and rear of the unit to ensure free circulation of air. Forced cooling is not required. The power supply is mounted on the bottom of the unit, and after a period of time it will feel hot to the touch at the bottom. This is normal, and should be no cause for alarm. To connect the PS 6379 onto the intercom system, use professional flexible microphone cable with 2 wires and

either the left or the right headset can, or to both headset cans.

An electronically balanced input allows volume controlled monitoring of the audio signal. This is for local use only, it will not appear on the intercom lines. Special attention has been paid to the intelligibility of speech. By applying low noise/high speed op-amps, a speech presence filter and a specially developed high power bridged headphone amplifier, communication is very comfortable even in environments with high background noise level. There is a separate amplifier for the loudspeaker.

The unique CALL system provides both a flashing red LED and a very distinctive and characteristic sound signal. A short push of the CALL button will make the LED flash. The Call sound signal (buzzer) will be activated when holding the button for two seconds. In case the sound signal is undesirable, all buzzers can be muted with the “All buzzers on/off” button and the volume of the buzzer can be adjusted at the front panel.

The pre-amplified microphone signal is electronically balanced available at a 3 pin male XLR. This signal can be sent to paging systems.

Fully electronic switching increases reliability and allows for :

- 'soft' microphone ON switching, latched or momentary

- remote Mic Mute facility.

- automatic speaker attenuation (adjustable), when the microphone is activated.

After unpacking the unit please inspect for any physical damage to the unit, and retain the shipping carton and relevant packing materials for use should the unit need returning.

If any damage has occured, please notify your dealer immediately so that a written claim can be initiated. Please also refer to the guarantee section of this manual.

1 shield only. Connect the system intercom cables into the LINE connector sockets on the rear panel. Finally, when private conversation is desired, connect the headset plug into the headset connector on the front of the front panel.

The PS 6379 is fully protected against mis-wiring (reverse power) or short circuit in the interconnect cables.

A special kit is included for mounting the PS 6379 in a 19" rack, taking 2U of rack-space.

5.0 MAINS POWER

The PS 6379 may be connected to the mains power outlet to which other audio equipment is connected. The outlet should have a clean earth. Avoid using mains power outlets, which also power dimmer controlled lighting equipment.

Before connecting the unit to its AC power source, check if the mains voltage of the unit (100 V – 240 V) is in accordance with your local mains voltage.

IMPORTANT

The wires in this mains lead are colour coded in accordance with the following code:

green and yellow / safety ground blue / neutral brown / live

This appliance must be earthed

5.1 POWERING UP

Powering up procedure:

- Make sure that the power switch at the back of the unit is OFF.

- Connect the power cord to the rear of the station.

- Plug the other end of the power cord into a PROPERLY GROUNDED outlet.

5.2 SAFETY EARTHING

The green-and-yellow wire of the mains cord must always be connected to the electrical installation safety earth or ground. It is essential for personal safety as well as for proper operation of the PS 6379 and the other connected stations. This wire is internally connected to all exposed metal surfaces. Any rack framework into which this unit

5.3 MAINS POWER SETTING

The unit has a switch mode power supply and accepts mains voltages from 100 – 240 VAC (50 / 60 Hz).

Mains Fuse

For all voltages : T 1250.

As the colours of the wires in the mains lead may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows:

- The wire that is coloured green-and-yellow must be connected to the terminal in the plug, which is marked with the letter “E”, or by the ground symbol, or is coloured green.

- The wire that is coloured blue must be connected to the terminal that is marked with the letter “N” or coloured black.

WARNING

- The wire that is coloured brown must be connected to the terminal that is marked with the letter “L” or coloured red.

Those units that are supplied to the North American market will have an integral moulded 3-pin connector, which is provided to satisfy required local standards.

- Turn on the power with the red button. The red overload LED will light up for about 3 seconds, then extinguishes and the green power LED will switch on, indicating the station is active.

might be mounted shall be connected to the same

grounding circuit.

The PS 6379 employs professionally designed audio input and output circuits which do not require the disconnection of any safety earth for the avoidance of hum loops.

6.0 FRONT PANEL CONTROLS & CONNECTOR

1 LISTEN LEVEL control knobs

These knobs preset the listen level for each channel

separately.

2 TALK buttons

These buttons allow you to talk to each channel separately or simultaneously. The large green LED is lit when the talk function for that channel is activated. Should one talk to a channel which is in IFB or PAGING mode by pressing and holding that TALK button, the other lit TALK buttons will switch off for as long as the IFB / PAGING mode TALK button is pressed (for further explanation of the Modes see section 9). To talk to an IFB / PAGING channel and additionally to a intercom channel, one should also press and hold the TALK button of the intercom channel. If in IFB mode and one would like to talk to all channels of which the TALK LEDs are lit, than this can be achieved by setting the corresponding, internal dip switch “IFB and TALK” to ‘on’ (see 8.0 Internal controls / Dip switches).

Latched switching:

When a TALK button is pressed shortly, the microphone signal is sent to the chosen channel and the TALK button latches electronically. When pressed again, the Talk function will switch off.

` Momentary switching:

When holding a TALK button pressed while talking, the microphone signal will be sent to the chosen channel until the button is released. Then the talk function will switch off automatically.

3 CALL buttons

These push buttons activate the call system, for each channel separately. A momentary push will sent a visual CALL signal to all stations connected to the intercom channel and the call LEDS will start flashing. When holding the CALL buttons for 2 seconds the buzzer will be activated, if there is no buzzer mute on this channel. After the CALL button is released the LEDS will continue to flash for further 2 seconds.

4 TALK to ALL

When the TALK to ALL button is pressed and held,

one will talk to all intercom channels simultaneously and the green LEDs of all channels will light up – except for the channels which are in IFB or PAGING mode. To also include the channels which are in IFB or PAGING mode, the dip switch IFB and TALK ALL has to be switched to ‘on’ (see 8.0 Internal controls / Dip switches).

5 CALL ALL When the CALL ALL button is pressed shortly a

visual call signal is sent to all channels and the red

LEDs will start flashing. When holding the CALL buttons for 2 seconds the buzzer will be activated, should no buzzer mute be activated for that channel. After the CALL button is released the LEDs will continue to flash for further 2 seconds. Channels which are in IFB or PAGING mode do not receive CALL signals.

6 MASTER VOLUME This knob adjusts the volume of the speaker or

headset.

7 STAGE ANNOUNCE This push button routes the microphone signal

directly to a line level output at the back of the unit. The microphone signal will not be sent to the intercom channel even if the TALK LEDs are lit. This can be changed by setting the corresponding internal dip switch (STAGE ANN. and TALK) to ‘on’ (see section 8.0 Internal controls / Dip switches). The Aux signal can also be routed to the STAGE ANNOUNCE output by setting the corresponding dip switch (AUX and STAGE ANN.) to ‘on’ (see section 8.0). In EXTENDED Mode only the microphone signal of the Master unit will be routed to the STAGE ANNOUNCE output of the master. This can be changed by setting the corresponding dip switch (Stage announce mic. Select) to ‘on’(see section 8.0) in which case each unit will use its own Stage Announce output and microphone.
