About This Product

ListenIR is an infrared hearing aid system that uses iDSP (Intelligent Digital Signal Processing), a unique technology that follows the infrared system "Stationary IR" series by Listen Technologies. This digital sound processor allows you to get much clearer sound. In addition, the new infrared receiver is equipped with a unique transparent plastic and two wide light receiving modules, achieving a light receiving range of nearly 360 degrees. In addition, the new infrared radiator enables a wide-angle emission range by combining a wide-angle high-power infrared emitter and a directional infrared emitter. These innovative products are compact in design and provide coverage beyond what traditional infrared systems can offer. In addition to fixed equipment, we also recommend using it in a portable manner. Of course, the infrared signal is the same as the Stationary IR series products, so they can be used in combination. Listen Technologies LT-84-01 is a ListenIR transmitter/radiator combo. Ideal for listening assistance in classrooms, courtrooms, theaters, and corporate meeting rooms. When used with LR-4200-IR/LR-5200-IR (receiver), it covers approximately 2787m². Also, when used with LR-42 (receiver), it covers approximately 697m². If you want to expand the coverage area, you can add up to 4 LA-141 (extension radiators). You can choose from 2.3MHz, 2.8MHz, 3.3MHz, and 3.8MHz frequencies.
