Williams Sound DL107 NET Digi-Loop Medium Area, Single Channel Hearing Loop Amplifier

Williams Sound DL107 NET Digi-Loop Medium Area, Single Channel Hearing Loop Amplifier The DL107 NET hearing loop amplifier utilizes advanced amplifier technology to enhance performance. It features network-control capabilities that allow for seamless remote system setup, operation, and monitoring of the induction loop system through a laptop or tablet. The digital signal processing (DSP) audio processing provides flexible and powerful software control for mixing, equalization, compression, and more. Additionally, the amplifier's Class D, pulse-width technology maximizes its efficiency. Designed for assistive listening, this system offers a single 9.5 A RMS loop output, suitable for perimeter loop or single array configurations. It includes a 70-100 V input that connects to a distributed speaker or paging system, ensuring that announcements are clearly heard by hearing aid users. The DL107 NET meets IEC 60118-4 standards for system performance when integrated into a properly designed and installed system. It has also been tested according to IEC Specifications 62489-1 Benchmark Standards. Features Network control – allows control and calibration of unit remotely with application software High continuous current 9.5 Arms (13.4 Apk) per output continuous LCD Screen with VU metering, easy one-button menu control DSP Audio Processing USB for firmware updates Input mixing, parametric equalization, compression, metal compensation, high and low-pass filters, AGC and audio delay Power-save mode Adjustable output delay for multiple amps in large venues Fault warning and active protection against shorted or open circuits and overheating Loop fault relay output XLR and 3-position terminal block input configurable as microphone input or line-input, balanced or unbalanced. Standard 1 RU, 19” rackmount Magnetic signal couples directly to devices equipped with telecoils (T-coils) such as hearing aids, cochlear implants, or optional loop receivers. DL207 suitable for phased-array or dual-loop systems; DL107 suitable for perimeter loop or single array. Phased-array mode automatically produces 90° phase shift in slave loop output Meets IEC 60118-4 system performance requirements when integrated into a correctly designed and installed system.
