1.0 GENERAL DESCRIPTION The PS 230 is a dual 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 230 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 sidetone trimmer.

7.0 CABLING For the PRO Series Intercom system the interconnecting cables are of the shielded two-conductor microphone cable type and the intercom line connectors are of the XLR-3 type. Audio and Call signals are on XLR pin 3, DC power is on XLR pin 2. XLR pin 1 is connected to the shield of the cable which functions as the common return for audio and power. ¼ Since the audio signal is transferred in an unbalanced way, certain rules have to be obeyed when installing the cables of an intercom network.

8.0 PARTY LINE, TECHNICAL CONCEPT ASL's PRO Series offers a complete two way ('full duplex') communications system. Users of the system are connected via a 'party line'. Master stations (with built-in power supply), beltpacks, speaker stations and power supplies are interconnected via standard microphone cable. One wire is used as an audio line, one as a power line and the screen of the cable functions as earth/return. Current drive is used for signal transfer.
