Infra Red Listening & Hearing Systems

An infrared listening system is one of the simplest, most secure methods of satisfying the requirements of the hearing impaired and the legeslation intended to protect them. IR listening systems provide audio amplication to loops, hearing aids or via a headset maintaining security without overspill.

Our infra-red systems, of varying output power, are designed for use in the home, at reception and counter areas, for committee and conference venues, in care homes, churches and other places of worship, schools, colleges and other education establishments, halls, leisure centres and in larger complexes.

The IRT-730R is a larger venue, infra-red, low band or high band (95/250 kHz or 2.3 /2.8 MHz, switchable) Transmitter Repeater Panel, complete with power supply unit and wall-mount bracket. It is designed for use with either the IRT-270 or the IRT-730 infra-red assistive listening transmitter to extend signal coverage up to approximately 730m2.

The unit is equipped with a 1/4" threaded mounting hole and can be screwed to a photographic tripod stand for portable use, or it can be wall-mounted with the supplied mounting bracket. The transmitter is for use with suitable receiver modules to be purchased separately.

ADSworldwide offers a number of options to accommodate both increased room size and different room configurations. Please contact our technical staff for the best solution applicable to your specific needs.
Please Note: Infra-red receivers operating in the low band (95kHz and 250kHz) can suffer from florescent lighting interference. In cases where high frequency florescent and/or incandescent lighting are used (this includes modern energy-saving lamps) the infra-red signal may become unusable. In these cases use the high frequency infra-red systems operating above 2MHz.
