  • Page 11: Party Line, Technical Concept

    PARTY LINE, TECHNICAL CONCEPT User stations and power supplies in an ASL intercom system are connected via one or several 'party lines'. A party line offers two-way (‘full duplex’) communication and consists of standard micro- phone (multi-pair) cable. One wire is used as an audio line, one as a power line and the screen of the cable functions as earth/return.
  • Page 12 Use high quality cable Use high quality microphone cable (shielded two conductor cable, minimum 2x 0.30 mm2). In case multi-pair microphone cable is used, there should be an overall shield and each pair should consist of two conductors (minimum 2x 0.15 mm2) with separate shield Use flexible cable Use flexible single and multi-pair microphone cable instead of cable with solid cores, especially when the cable is subjected to bending during operation or installation.

  • Page 13: System Configuration

    ASL powered units to a 'clean' mains outlet Master stations or power supplies should be connected to a mains outlet with a clean earth. Other audio equipment may be connected to this mains outlet, but avoid using an outlet which also powers dimmer controlled lighting systems.
