LOOP AMPLIFIER SYSTEM

Above Counter Kit

Our Above the Counter Loop System provides clear communication with hearing instrument wearers, especially where background noise is a problem or clear speech is restricted.

The hearing loop aerial is located within the signage, which is fixed to a counter, desk or glass surface to enable customers to easily identify the loop and get maximum benefit from it. The unit can be fitted into many positions due to its low profile structure.

Includes:

• HLD2 loop driver – Our innovative 1 to 1 Hearing Loop Driver is a special type of audio amplifier designed especially for driving hearing loops.
• IL-AE97-00 hearing loop sign with integrated loop aerial – The Supaloop Aerial is a hearing loop aerial built inside of our blue hearing loop sign, enabling the telecoil in a hearing instrument to receive a signal from drivers.
• STS-M72 cardioid LED halo desktop mic with short plastic stem – Our Halo Microphone with Stem features noise cancelling and a halo light indication at the base of the microphone stem. The halo lights up green when the system is working correctly and red when a fault is detected. It can be either screwed down or mounted using a standard self-adhesive pad, while the microphone is available in metal or without a halo LED indication.
• PS-55-01 power supply – The PS-55 Power Supply is a Level VI power supply for use with our Under the Counter Loop System, Above the Counter Loop System and Home Loop Kit.
