Williams AV DL207 SYS D Digi-Loop Medium Area Dual Channel Hearing Loop Dante System

Williams AV DL207 SYS D Digi-Loop Medium Area Dual Channel Hearing Loop Dante System

Introducing the DL207 SYS D Hearing Loop System: A Modern Solution

The DL207 SYS D hearing loop system is equipped with advanced amplifier technology that maximizes its performance. The system features network-control capability, which allows for remote operation, set-up, and monitoring via a laptop or tablet. Additionally, the DSP audio processing offers powerful software control of mixing, equalization, compression, and more. The unit's powerful Class D pulse-width amplifier provides maximum efficiency, while the Dante™ input enables integration with existing Dante™ devices and remote network management.

The assistive listening system's design is impressive with its dual 9.5 A rms loop output for dual loop or phased array configuration. A 70-100 V input connects to a distributed speaker/paging system to ensure announcements are heard by hearing aid users.

The DL207 SYS D is compliant with IEC 60118-4 standards for system performance when integrated into an appropriately designed and installed system. It has also been tested to IEC Specifications 62489-1 Benchmark Standards.
