1.0 INTRODUCTION
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 and a
two-stage side tone trimmer. A master volume
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 when
the microphone is active. Private conversation may
be carried out with a headset or telephone handset
connected to the unit. When a headset is plugged in,
both gooseneck microphone and loudspeaker are
disabled automatically.
As an option, a XLR-5 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.
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 back-
ground 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 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
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. This signal may be sent to any PA
or paging system.
Fully electronic switching increases reliability and
allows for :
'soft' microphone ON switching, latched or
momentary
remote Mic Mute facility
automatic speaker attenuation, when the
microphone is activated
