1.0 GENERAL DESCRIPTION The PS 260 is designed to interface the ASL intercom system (party line) to external audio equipment or 4-wire communication systems. The PS 260 includes two separate interfaces which are completely identical. Each interface is power supplied via the intercomline. For example a fixed cabled (4-wire) intercom system can temporarily be extended with a portable ASL set, for use on location or a (4-wire) camera CCU can be connected to the ASL intercom system.

.0 4 FRONT PANEL CONTROLS The PS 260 consists of two separate interface modules in one housing. Each module interfaces between ASL 3-wire systems and 4-wire systems. The signal on the audio wire of the ASL 3 wire system is converted in a balanced signal and appears on the audio output connector. Signals offered to the audio input are placed on the audio wire of the 3-wire intercom line connector.

.0 REAR PANEL CONTROLS At the rear panel you will find the connectors for interconnecting the PS 260 with the ASL intercom system(s) and the connectors for connecting 4-wire systems or audio equipment. 8 9 6.0 AUDIO INPUT connector This XLR-3 connector is for placing an audio signal on the intercomline. It is electronically balanced in the standard version. An extra balancing transformer is optional (PS 260/T). Pin assignments : 1. 0V / ground shield 2. signal + 3.

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.
