The DL210 SYS 2 2.0 hearing loop system maximizes modern amplifier technology. Its network-control capability provides seamless, remote system set-up, operation, and monitoring of the induction loop system via a laptop or tablet. DSP audio processing offers flexible, powerful software control of mixing, equalization, compression, and more. Powerful Class D pulse-width amplifier maximizes the efficiency of the unit.

This assistive listening system’s design offers a dual 12 A rms loop output for dual loop or phased array configuration. A 70-100 V input connects to a distributed speaker/paging system, ensuring announcements are heard by hearing aid users.

Meet IEC 60118-4 standards on system performance when integrated into a correctly designed and installed system. The DL210 SYS 2 2.0 is also tested to IEC Specifications 62489-1 Benchmark Standards.
