More Information

An under-counter loop system that enables clear communication with hearing instrument wearers, especially where background noise is a problem or clear speech is restricted. It has a flexible, discreet hearing loop aerial that can be bent to shape, allowing it to be tailored to many different counters.

The box for this item contains :

  • 1 to 1 hearing loop driver
  • Power supply with 2m IEC lead
  • Halo microphone
  • Counter hearing loop aerial
  • Signage
  • Fixings
  • Microprocessor control
  • Energy-saving “green” standby mode, achieves a power saving of up to 80% during quiet periods
  • Advanced audio processing features, including AGC, compression and noise gate
  • Constant-current loop drive
  • Continuous self-testing
  • Isolated audio line input allows the driver to take alternative audio sources (optional)
  • Power and LED status indication
  • Magnetic field range of 1200mm
