HLD7 Hearing Loop Driver



Contacta HLD7 is a modular hearing loop driver for perimeter or phased array configurations, suitable for medium-sized facilities, meeting rooms, lecture halls, places of worship and small theatres. Ultra efficient management of power enables the unit to be extremely compact.

HLD7 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 HLD7 as simple as possible, the driver includes sophisticated communications capabilities enabling remote set-up and control of levels as well as system interrogation and performance monitoring.


Suitable for medium-sized facilities such as:

  • Meeting and conference rooms
  • Lecture halls
  • Places of worship
  • Nursing and care homes
  • Reception and waiting areas
  • Small theatres
  • Gym and sports halls


  • Built-in 90º phase shift
  • Flexible configuration
  • Ultra-efficient power utilization
  • Sleep mode
  • High frequency compensation
  • Continuous self-testing
  • Accurate, lockable controls (front panel mounted)
  • Input and drive level indication
  • Intelligent protection system
  • Flexible audio inputs
  • 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.
