IR T2 Medium-Area Infrared Transmitter Features

When used with the RX22-4N receiver, the IR T2 medium-area infrared transmitter covers an area of 18,000 square feet with clear, low distortion audio, making it easy to provide a quality service, indoors or outside. No secondary units are needed due to the extra wide range and coverage pattern.

Perfect for conferences, meetings and courtrooms, the IR T2 transmitter requires no license to operate and comes with pre-set music and voice settings, so no complicated audio configuration or government licensing.

Because IR signals do not go through walls, you can be assured that all audio stays within the room.
