Williams AV DL210 NET D 2.0 Digi-Loop Large Area Dual Channel Hearing Loop Dante Amplifier

Williams AV DL210 NET D 2.0 Digi-Loop Large Area Dual Channel Hearing Loop Dante Amplifier

DL210 NET D 2.0: The Ultimate Hearing Loop Amplifier

An induction loop system that maximizes modern amplifier technology, the DL210 NET D 2.0 offers seamless and remote system set-up, operation, and monitoring of the loop system via a laptop or tablet. With DSP audio processing, the unit provides flexible and powerful software control of mixing, equalization, compression, and more. The powerful Class D pulse-width amplifier also maximizes the unit's efficiency.

The Dante™ input enables integration with existing Dante™ devices, allowing for remote network management. Additionally, the DL210 NET D 2.0 boasts a dual 12 A rms loop output for dual loop or phased array configuration, and a 70-100 V input that connects to a distributed speaker/paging system, ensuring that announcements are heard by hearing aid users.

The assistive listening system meets IEC 60118-4 standards on system performance when integrated into a correctly designed and installed system, and is tested to IEC Specifications 62489-1 Benchmark Standards.
