Williams AV DL107 NET D Digi-Loop Medium Area Single Channel Hearing Loop Dante Amplifier

DL107 NET D Hearing Loop Amplifier - Advanced Features for Optimal Performance

The DL107 NET D hearing loop amplifier represents the best of modern amplifier technology. With network-control capability, you can set-up, operate, and monitor the system remotely via a laptop or tablet. The DSP audio processing makes it easy to control the mixing, equalization, compression, and other features.

This assistive listening system is designed to provide a single 9.5 A rms loop output for perimeter loop or single array configuration. Additionally, the 70-100 V input connects to a distributed speaker/paging system to ensure that announcements can be heard by hearing aid users.

The DL107 NET D meets the 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. With the Dante™ input, you can integrate existing Dante™ devices and employ remote network management to optimize performance.
