1.0 GENERAL DESCRIPTION The PS 680 is designed to be a six channel power supply in an ASL intercom system and can be used in portable as well as fixed applications. It incorporates two adjustable auxiliary program signal inputs with a auxiliary matrix and uses only 1U of 19" rack space. The unit is very versatile and ideal for use in applications where standard microphone cable is available and ease of setup is of paramount importance.

5.0 FRONT PANEL CONTROLS 1 POWER ON/OFF switch Mains power push button for switching ON and OFF the internal power supply. 2 OVERLOAD LEDS These LED’s illuminate if the internal power supply has shut off line power due to overload. If the internal power supply is overloaded (too many user stations are connected or short-circuit in the interconnecting cables or thermal overload), it activates a circuit-breaker which immediately shuts off line power.

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. 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.
