1.0 GENERAL DESCRIPTION The BS 216 is designed to be a master unit in an ASL intercom system and can be used in portable as well as fixed applications. It incorporates a dual channel intercom line power supply with aux input, a dual channel headset station and uses only 1U of 19" rack space. This makes the BS 216 very versatile and ideal for use in applications where standard microphone cable is available and ease of setup is of paramount importance.

4.0 MAINS POWER The BS 216 may be connected to the mains power outlet to which other audio equipment is connected. The outlet should have a clean earth. Avoid using mains power outlets which also power dimmer controlled lighting equipment. The used AC power source can be anything from 100 240 V AC, 50/60 Hz. There is no need to adjust the unit to the used mains voltage.

8.0 CABLING For the BASIC 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.

9.0 PARTY LINE, TECHNICAL CONCEPT ASL's BASIC 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 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.
