Infrared works just like white light that you see, except it has a longer wavelength and is not visible to the human eye. The audio signal is transmitted by an infrared beam throughout the room and is received by a receiver designed to receive the signal and process it back to audio for the listener.
Advantages
- More consistent reception
- Excellent sound quality
- Usually not susceptible to interference from external sources
- Transmission is confined within a room where security is a concern
- Easily accommodates multiple and adjacent room installations without spillover or cross-interference
- Can be used in any country. Not regulated like RF
- Infrared light is reflected by light-colored floors, ceilings and walls to increase coverage
- Receiver automatically picks up the correct channel in adjacent room applications
- Multiple channels can be used for multiple languages
