PRO/DW Phase-Shifting Loop Amps

A range of high performance wall-mounting constant current phase-shifting loop amplifiers with Class D output stages for maximum efficiency.

  • Perfect for areas where minimal overspill and consistent coverage (i.e. no dead spots) is essential.
  • Intuitive graphical interface allows simple set-up of input levels, output current, phantom power and metal compensation.
  • 200m2, 500m2 or 1000m2 coverage (model dependent).
  • 1 x mic, 1 x line and 1 x optical TOS link input to facilitate easy connection to TVs, soundbars, etc.
  • Outreach connector allows up to 10 of our revolutionary audio input utility plates to be added
  • Anti-tamper lock function prevents unauthorised adjustment of system settings
  • Class D output stage for maximum efficiency and very high output
  • Superior analogue audio processing with a powerful CPU and cutting-edge technology provide life-like speech and frst class music reproduction
  • Short circuit protection against loop faults for increased reliability
  • Fault relay & graphical display provide clear indication of operation and fault status
  • Industry leading dual action automatic gain control compensates for poor microphone technique
  • Line level output for recording or daisy-chaining multiple units to cover larger areas.
  • Exceeds the requirements of PD IEC TR 63079 & EN 60118-4 when correctly installed and complies with EN 62368-1.
  • Designed and manufactured in the UK.
