75 OHM RF CABLE The round cable that comes from an off-air antenna or cable service
provider. Each end looks like a hex shaped nut with a wire sticking
through the middle, and it screws onto the threaded jack on the back of
your TV.
A/V CABLES Audio/Video cables. Three cables - Right audio (red), Left audio (white),
and Video (yellow). A/V cables are used for stereo playback of videocas-
settes and for higher quality picture and sound from other A/V devices.

or television).

that you’ll scroll through when using your remote.

DVD or other A/V device.

DOLBY DIGITAL Dolby Digital Cinema Sound is made possible by a new digital coding tech-
nique called Dolby AC-3. Dolby AC-3 produces high-quality, 5.1 channel
surround sound which is six discrete separate channels for a full range of

center, front left, front right, surround left, surround right and subwoofer).
