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.
- The emitter does not focus the emission of the infrared light impulses, i.e. it uses a very large transmission angle. As a result, there is generally no need for a specific »line of sight« between the emitter and the receiver.
- The signals do not only travel directly between the emitter and the receiver, but are also reflected from walls, ceilings and floors. Nevertheless, pillars and furniture – depending on their size and position – can interfere with or even block reception under certain conditions.
In any case, a technically correct, precise positioning of the emitters is required for optimal signal coverage.
