Interference-free and secure supply of rooms and halls with audio signals – also for use in confidential areas

An IR audio transmission system consists of at least one transmitter and one receiver. The transmitter is connected to an audio source and transmits the recorded signals in the form of infrared light pulses wirelessly to the respective receivers. These convert the received light pulses into electrical audio signals and feed them into the hearing components - for example into headphones or a neck loop for inductive direct transmission to hearing aids.

In any case, a technically correct, precise positioning of the emitters is required for optimal signal coverage.
