Infrared system
In event technology, an infrared system has the task of converting acoustic signals into optical signals, transmitting them and then making them audible again. This is done with an infrared transmitter, which converts the electroacoustic signals generated by a sound source (e.g. PC or control center) into high-frequency electrical signals and feeds them to infrared radiators. These radiate the room with non-visible infrared light. The wavelength of infrared light is in the range of 880 to 950 nm. The reconversion into acoustic signals is carried out with a Infrared receiver and an earphone.
Advantages of infrared transmission technology are:
- Wireless transmission
- High quality intelligible transmission
- The transmission is limited to closed rooms and is therefore tap-proof.
- Multi-channel/multi-language transmission is possible without any problems
- Immunity to electromagnetic interference
