An HD (high definition) box typically refers to the electronic component that receives a cable TV signal and sends it along to a connected television. Modern HD boxes are equipped with a variety of jacks, inclduing digital audio outputs for connecting cable service to a home theatre sound system. The signal from the HD box may carry up to eight channels of audio for a 7.1 surround sound system. A single digital cable connects the box directly to the audio input on the sound system receiver.
