Williams Sound DL 102Counter Loop Amp for T-coiled Hearing Devices


A Loop amplifier from Williams AV, their DL102 brings forth a practical solution to enable a user to hear with their T-coil enabled hearing device in small areas such as counters and service desks. Audio is fed into the DL102 amplifier via a line-level input or microphone. Then, the audio is sent from the amplifier through the loop wire situated in the area where a T-coiled hearing device can provide pick-up of the audio.

With no connection directly between the user and service personnel, the user can hear effectively when using the T-coil within their customized hearing devices. This system is supplied with a loop pad and a spool of wire.
