GENERAL DESCRIPTION
The PS 430 is a four channel speaker station designed for use in an ASL intercom system
and provides full duplex communications.
It incorporates a loudspeaker, a gooseneck microphone and a headset connector.
The PS 430 RM model has a small built-in electret mic instead of a gooseneck mic.
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 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. Loud-
speaker dimming is automatic if the gooseneck microphone is active.
The XLR-4 headset connector allows connecting a headset or telephone handset.
If a headset is connected, both gooseneck microphone and speaker are disabled auto-
matically.
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 environ¬ments with
high back¬ground noise level.
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 will activate the CALL sound signal. The volume of the sound signal
(buzzer) can be adjusted at the front panel.
Fully electronic switching allows for 'soft' microphone ON switching (latched or momen-
tary), remote Mic Mute facility and automatic speaker attenuation.
