Contacta HLD9 induction loop amplifier

This 2u, half rack size single output hearing loop driver is designed for use in larger sized venues such as theatres, conference facilities, sports arenas, concert halls and auditoria. A single HLD7 can be used to provide a perimeter loop system, or two HLD7 loop amplifiers can be linked by a RJ45 cable to provide a phased array configuration ensuring every seat receives high quality AFILS

As a Class D driver, it manages power extremely efficiently, meaning that it emits very little heat from its compact packaging. To make the experience of using it as simple as possible, the driver includes sophisticated communication capabilities, enabling remote set-up and control of levels, as well as system interrogation and performance monitoring

Complies with the following standards: FCC class “B” EMC (emissions); IEC 60118-4:2006 (in correct installations); BS EN 55103-1:2009 (EMC emissions); BS EN 55103-2:2009 (EMC immunity)
