IRMO

Infrared AudioTransmitter & Receiver System

 

Infrared Transmitter and receiver for audio - Mono. Consists of a transmitter that generates an FM carrier and places this on an infrared light beam, and a receiver that detects this light beam, recovers the modulation, and amplifies it to drive a small spealer or headphone. Up to 1 watt audio output. Useful for private audio listening, infrared communication, remote sensing, security applications. Signal is undetectable visually or with a surveillance receiver. Both units operate from 9 to 12 volt DC supplies.
