GENERAL DESCRIPTION

The PS 630 is a six channel speaker station designed

for use in both portable and fixed intercom systems.

It incorporates a loudspeaker and a gooseneck

microphone and provides full duplex communications

within an ASL intercom system. The PS 630 RM model

has a small built-in electret microphone.

Each channel has a Volume (listen level) control, a

Talk and Call button with LED indicators, channel

on/off switch and a two-stage sidetone trimmer. A

master volume controls the total speaker/headset

volume.

The unit is equiped 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 disabled

automatically.

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 either the left or the right headset can, or

to both headset cans.

An electronically balanced input allows volume

controlled monitoring of an audio signal. This is for

local use only, it will not appear on the intercomlines

INSTALLATION

This PS 630 will form part of an existing or new

intercom system, and connection to it is

straightforward. There are no separate power

connections or batteries to install, as the necessary

DC voltages are derived from the intercom master

station or power supply, via the intercom connection

cable.

To connect the PS 630 onto the intercom system, use

professional flexible microphone cable with 2 wires

Special attention has been paid to the intelligibility of

speech. By applying low noise/high speed opamps, a

speech presence filter and a specially developed high

power bridged headphone amplifier, communication is

very comfortable even in environments with high back-

ground noise level. There is a separate amplifier for

the loudspeaker.

The unique ASL CALL system provides both a flashing

red LED and a very distinctive and characteristic

sound signal. Smooth operation is guaranteed with the

CALL button. Only a slight touch makes the red LED

flash, whilst holding the button for two seconds will

activate the CALL sound signal. The volume of the

sound signal (buzzer) can be adjusted at the front

panel.

The preamplified microphone signal is electronically

balanced available at a 3 pin male XLR. This signal can

be sent to paging systems
