The 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 theaters. Ultra efficient management of power enables the unit to be extremely compact. The 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. We have done this 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.
