6.0 THE INTERCONNECTING CABLE Special care must be taken in constructing the interconnection cable. Although ASL-intercom has taken great care in shielding and filtering all RF components from the unit, it is still very important that you use the best quality cables and properly construct any electrical and mechanical construction. The TRANSMIT SWITCH contacts These are located on pins 4, 5 and 6. Most wireless units will need a contact to be closed to change from receive to transmit.

7.0 SIDETONE ADJUSTMENT PROCEDURE 8.0 VOX ADJUSTMENT PROCEDURE • Connect the interface with a proper cable to the wireless unit. Before this procedure is done the SIDETONE must have been adjusted properly ! • If the wireless unit has a volume control turn it down (volume approx. 10%, a volume that is too high can cause problems such as distortion).

10.0 INTERNAL CONTROLS To access these trimmers you need to open up the unit. Disconnect the unit of all other equipment and then remove the cover. - Open the PS 155 by removing the two screws at either side. Then carefully connect the unit to the intercom and to the wireless unit. OUTPUT GAIN (R4) The output gain can be adjusted internally by a trimmer R4. The trimmer is located on the PCB board at the left, near to the transformers. To increase mic gain turn clockwise.

11.0 CABLING For the BASIC Series Intercom system the interconnecting cables are of the shielded twoconductor 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. ! Use high quality (multipair) cable.

12.0 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 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.
