Digital Audio Outputs (Optical Jack and Cable)
Th e Digital Audio Optical cable provides the best quality audio. Th e jack and cable use light to send
digital audio data to A/V receivers equipped to receive and interpret it. Th e jack and cable must be
aligned before plugging in, and may be covered by protective caps, which must be removed before
making connections. Use caution when handling optical cables: Th ey are delicate!
S-Video Jack and Cable
S-Video jacks and cables provide the best non-HD picture quality. You will still need to connect the
left and right audio cables to the TV, or digital audio (optical or coax) cable to your stereo, because the
S-Video cable only carries the picture signal, not sound.

Audio/Video (A/V) Jack and Cable
Audio/Video (A/V) cables provide very good picture quality and stereo sound, and should be used if
you don't have HDMI, component or S-Video cables, or your TV does not have HDMI, component or
S-Video jacks. Th e DIRECTV HD Receiver's A/V jacks are color coded (yellow for video, red for right
audio and white for left audio). If your TV has only one input for audio (mono), connect it to the left
(white) audio jack on the DIRECTV HD Receiver.
