GENERAL DESCRIPTION
The PS 430 is a four channel speaker station
designed for use in both portable and fixed intercom
systems. It incorporates a loudspeaker, a gooseneck
microphone and a headset connector.
The unit provides full duplex communications within
an ASL intercom system.
The PS 430 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 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 with a headset or telephone handset
connected to the unit. When a headset is connected,
both gooseneck microphone and speaker are
disabled automatically.

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 background 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.
Fully electronic switching increases reliability and
allows for :
o
'soft' microphone ON switching, latched or
momentary
o
remote Mic Mute facility.
o
automatic speaker attenuation when the
gooseneck microphone is activated.
