Contacta IR-TX4 Large Area Infrared Transmitter



The Contacta IRTX4 is a two-channel Large Area Infrared Transmitter, with a combined Modulator. This product generates a wide exit angle for the infrared signal while providing a sleek and compact design that eliminates the need for rack space. It is ideal for use in large environments.

Transmissions are at a bandwidth of 2.3 and 2.8mHz. In 1-channel mode, the transmitter supplies areas of up to 900m². Additional transmitters allow the receiving range to be increased.

The IR-TX4 must be used in conjunction with either the IR-RX2 Receiver and IR-NL1 Neck Loop, or even an IR-RXU Underchin Receiver Unit. It is ideal for use in any situation where Infrared Systems can provide multiple listeners with clear sound, for example:


  • Courts
  • Places of Worship
