GENERAL DESCRIPTION
The PS 230 is a dual channel speaker station
designed for use in an ASL analog intercom
system and provides full duplex communications.
The unit incorporates a loudspeaker, a
gooseneck microphone and a headset connector
The PS 230 RM model has, instead of a
gooseneck mic, a small built-in electrets mic.
Each channel has Volume (listen level) Control, a
TALK and CALL button with LED indicators and a
2-stage side tone trimmer. There is a trimmer for
speaker attenuation and one for buzzer 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 if the
gooseneck microphone is active.
Private conversation may be carried out via a
headset or telephone handset plugged into the
headset connector. If a headset is connected,
both the gooseneck microphone and speaker are
disabled automatically.

INSTALLATION
Connect the intercom party lines to the LINE
connectors on the side panel of the PS 230.
The necessary DC voltages are derived from a
master station or a separate power supply, via the
intercom connection cables. Use professional
microphone cable with 2 wires and 1 shield only.

The XLR-4 headset connector can be replaced
(by ASL) by a XLR-6 connector for binaural use of
the headset.
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 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 characteristic sound
signal (the buzzer). 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 this signal (the buzzer) can
be adjusted at the front panel.
Fully electronic switching allows for 'soft'
microphone on switching (latching or momentary),
remote Mic Mute facility and automatic speaker
attenuation.
The PS 230 is fully protected against wiring
mistakes (reverse power) or short circuit in the
interconnecting cables.
A kit is available for mounting the PS 230 in a 19"
rack, taking 2U of rack space.
