HLD5 Hearing Loop Driver



Contacta HLD5 is a standalone dual hearing loop driver with integral phase shifter for perimeter or phased array configuration, suitable for smaller facilities including meeting rooms, classrooms and similar sized venues. Ultra-efficient management of power enables the unit to be extremely compact.

HLD5 is part of a new generation of drivers based on cutting edge loop technology aimed at taking the complexity out of loop design and specification, by allowing equipment and configuration to be determined by performance requirements rather than area. This has been achieved by designing drivers that are feature-packed, flexible, efficient and ultra-reliable.

To make the experience of using Contacta HLD5 as simple as possible, the driver includes sophisticated communications capabilities enabling system interrogation and performance monitoring.


Suitable for smaller facilities such as:

  • Meeting rooms
  • School rooms
  • Nursing and care homes
  • Reception and waiting areas
  • Gym and sports halls
  • Educational establishments


  • Flexible configuration
  • Built-in 90º phase shift
  • Ultra-efficient power utilization
  • Sleep mode
  • High frequency compensation
  • Continuous self-testing
  • Drive level indication
  • Intelligent protection system
  • Interface to external communication device


Specifying loop equipment and configuration by area can be misleading and lead to poor performing loop systems. Contacta is spearheading a new simpler approach to loop system design and specification by producing a range of drivers that are the most sophisticated and efficient on the market, allowing sufficient headroom to cope with any situation providing a thorough survey of the facility has been carried out and test measurements taken.
