Digi-Loop Counter Hearing Loop Amplifier

DL 102

The counter hearing (induction) loop amplifier, DL102, extends hearing support to those with T-coil-enabled hearing aids and cochlear implants at counter settings such as reception desks or ticket counters.


The DL102 fixed counter induction loop amplifier enables venues to link an audio signal such as an audio device, microphone, or TV to the loop system, ensuring assistive communication is available for T-coil hearing aid users at counter settings.

Once installed, it provides the venue with a cost-effective and low-maintenance solution to adhere to IEC 60118-4 standards for accessibility and hearing assistance compliance. Pair the induction loop system with accessibility sign to inform hearing aid users of available hearing assistance.
