Product Description

The AD903 2 to 4 wire adapter allows connection of almost any audio source to a Tecpro ring intercom 2 wire system. For example, most broadcast video cameras have in-built 4 wire comms systems which are cabled within the main video cable. Use of an AD903 at the camera control unit will allow that camera to appear as a part of the Tecpro communication system, while minimising extra wiring and expense.


  • Input and output on 4-wire side are transformer balanced, isolated and floating - reduces likelihood of hum and interference
  • Very wide input and output ranges - will interface to mic or line level systems
  • Sidetone null adjustment to minimise input to output cross talk
  • All presets are multiturn types for easy adjustment
  • Industry standard XLR type connectors
