LOOP AMPLIFIER SYSTEM

Under Counter Kit

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

It has a flexible, discreet hearing loop aerial that can be bent to shape, allowing it to be tailored to many different counters.

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-SN hearing loop sign – Signs are available as either stand-up signs or stickers, available for both portable and fixed loops. Stickers are available with either an adhesive back or an adhesive front.
• IL-AE99 loop aerial – Our Counter Hearing Loop Aerial is for use with the Under the Counter Loop System, which is fixed under desks or counters.
• STS-M74 anti-vandal discreet mic – Our Discreet Microphone is a compact solution for mounting to tills or computer screens. It is fitted using an attached bolt and comes with a double-sided connector. It is also available with a right-angled bracket for fixing to screens.
• 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.
