Product Overview
Designed for large spaces, the DL210 NET 2.0 hearing loop amplifier extends support to those with T-coil-enabled hearing aids and cochlear implants, making it an ideal solution for venues like auditoriums and gymnasiums. Its network-control capability allows for seamless remote setup, operation, and monitoring via laptop or tablet, while DSP audio processing offers flexible control over mixing, equalization, compression, and more. Featuring a powerful Class D pulse-width amplifier, this amplifier maximizes efficiency, delivering a dual 12 A rms loop output for dual loop or phased array configuration. With a 70-100 V input for connection to a distributed speaker/paging system, announcements are sure to be heard by hearing aid users. Meeting IEC 60118-4 standards for system performance and adhering to IEC Specifications 62489-1 Benchmark Standards, the DL210 NET 2.0 is a reliable choice for enhancing accessibility in public spaces.
