IRRXQ Infrared receiver with neck loop

The IR-RXQ is a compact receiver for infrared assistive listening systems, and forms the user component in the Infra~HearTM range of products.

Using high frequency modulation at 2.3MHz the IR-RXQ is immune to interference from energy saving lighting and plasma displays.

The receiver is battery powered from standard AAA batteries with a life of over 30 hours between charges, saving the expense of custom battery packs and chargers.

The volume control has a positive snap, and enables users with limited mobility to use the system.

The ability to add external headphones allows the receivers to be used by non hearing aid wearers in museum tour guide systems or for secondary language translation systems, or simply to test operation of the receiver without stocking two receiver types.

Infra red light will not pass through walls, ensuring security in sensitive locations such as courts and council chambers.
