Williams AV DL107 SYS Digi-Loop Medium Area Single Channel Hearing Loop System

DL107 SYS Hearing Loop System: A Modern Marvel in Sound Technology

The DL107 SYS hearing loop system utilizes state-of-the-art amplifier technology to deliver incredible performance. It features network-control capability, which enables remote system set-up, operation, and monitoring from a laptop or tablet. With DSP audio processing, the unit provides flexible and robust software control of mixing, equalization, compression, and other audio features.

The system is designed to offer a single 9.5 A rms loop output for perimeter loop or single array configuration. A 70-100 V input connects to a distributed speaker/paging system, ensuring that hearing aid users and visitors receive announcements loud and clear. The package includes two body-pack loop receivers with earbuds.

The DL107 SYS meets IEC 60118-4 standards on system performance when integrated into a correctly designed and installed system. It has also been tested to IEC Specifications 62489-1 Benchmark Standards.
