1.0 INTRODUCTION
The PS 630 is a six channel remote speaker
station designed for use in an ASL Intercom
system. It incorporates a loudspeaker, a
gooseneck mic and a headset connector and
provides full duplex communications.
The PS 630 RM model has, instead of a
gooseneck mic, a built-in electret microphone.
Each channel has a Volume (listen level) control,
a TALK and CALL button with LED indicators and
a two-stage side tone trimmer.
A master volume knob controls the
speaker/headset volume.
The unit is equipped with a limiter for the
gooseneck microphone, allowing to speak close
into the microphone without giving rise to
overload and distortion.
Loudspeaker dimming is automatic if the
microphone is active.
If a headset is plugged in, both gooseneck
microphone and loudspeaker are disabled
automatically.
As an option, an XLR-6 headset connector can be
fitted for binaural use of the headset: each
channel can be assigned to either the left or the
right headset can, or to both headset cans.
2.0 INSTALLATION
To connect the PS 630 to the intercom system,
use professional microphone cable with 2 wires
and 1 shield only. Connect the intercom cables to
the LINE connector sockets at the rear panel.

The PS 630 has an electronically balanced
program audio input for local volume controlled
monitoring only. The program audio does 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 proprietary
and bridged headphone amplifiers,
communication is very comfortable even in
environments with high background noise level.
There are separate amplifiers for headset and
loudspeaker.
The unique ASL CALL system provides both a
flashing red LED and a very distinctive sound
signal. Only a slight touch of the CALL button
makes the red LED flash, whilst holding the
button for two seconds activates the Call sound
signal. The volume of the sound signal (buzzer)
can be adjusted at the front panel.
The pre-amplified microphone signal is
electronically balanced available at the 'Mic Direct
Out' connector at the rear panel.
Fully electronic switching increases reliability and
allows for 'soft' microphone on switching (latched
or momentary), remote Mic Mute facility and
automatic speaker attenuation.
The PS 630 is fully protected against eventual
wiring mistakes (reverse power) or a short circuit
in the interconnect cables.
A kit is included for mounting the PS 630 in a 19"
rack, taking 2U of rack space.
