The Williams AV DL102 Loop amplifier provides a practical solution for a user to hear with their T-coil enabled hearing device in small areas such as counters and service desks.

Audio is wired into the DL102 amplifier via a line-level input or microphone. Audio is fed from the amplifier through the loop wire in the area where a T-coiled hearing device can pick-up the audio.

With no direct connection between the user and service personnel, users can hear effectively when using the T-coil in their customized hearing devices.
