Wireless Audio Transmitter for TV
This project allows you to watch your favourite TV programmes late at night without disturbing other family members. The project uses a FM transmission principle. Most modern TVs are nowadays equipped with audio-in/out and video-in/out RCA sockets.
Using an RCA-to-RCA cord, connect the audio output of your TV to the transmitter’s input. Adjust the gain of the audio preamplifier for clear reception in a portable FM receiver equipped with an earphone socket.
