Short definition
An infrared system is a wireless transmission system that carries audio signals via infrared light – the technical foundation for language distribution in simultaneous interpreting.
Detailed explanation
The term infrared system describes the transmission method in general, independent of the specific application. Core components are the transmitter/modulator, infrared emitters, and receivers. The principle is the same as with the infrared interpreting system: sound is converted into modulated infrared light, distributed through the room, and converted back at the receiver.
Typical characteristics: confined to the room (light doesn't pass through walls), therefore secure and free from radio interference, but dependent on line of sight and sensitive to strong ambient light. The technology is used wherever audio signals – usually multiple channels at once – need to be distributed wirelessly within a room. In an interpreting context, the infrared system is thus the base technology on which the infrared interpreting system and multi-channel distribution are built.
Relevance in this subject area
The infrared system is the foundation of confined, secure language distribution. Knowing its properties helps plan emitter count and placement correctly.
Practical example
For a board workshop, an infrared system is chosen precisely because the signal doesn't leave the room – confidential content stays physically contained.
