There are four main components to the Value Package – the transmitter, antenna, receiver and input source.
The input source can be audio from a sound board, microphone or a personal audio source like a CD player,
MP3 player, computer, DVD, etc. Audio will be connected into the audio inputs of the Stationary Transmitter.
