How it Works

1. The source of sound sells the sound track by the cable to the transmitting station
2. The transmitting station transforms the sound track into FM signal with the appropriate frequency and sends it
3. The loud speaker works on the same frequency
4. When the signal is recognized it goes to the amplifier and sends it to the loud speaker that play the sound
