Th
e recommended audio format for HDTV is Dolby® Digital.
Your DIRECTV HD Receiver is capable of reproducing 5.1-encoded audio: fi ve discrete channels of
full-range digital audio, plus one channel of low-frequency (subwoofer) audio, for use by A/V receivers
capable of decoding the 5.1-channel signal. Th
e audio signals are broken into left-front, center, right-
front, left-rear, right-rear and low-frequency channels. Th
e result, when your DIRECTV® HD Receiver
is connected to a compatible Dolby Digital A/V receiver and 5.1 channel speaker setup, is an experience
that gives you much of the dynamic range, 360-degree imaging and sonic excitement of a real theater.
Not all TV programs deliver 5.1 channel signals, and not all programs are broadcast using Dolby Digital
for DIRECTV® programming. Programs using this high-quality audio standard are indicated by the
words Dolby Digital in the program description in the Channel Banner (see page 13) and the Guide (see
page 15).
To change the Digital Audio format, press MENU, select
Help & Settings,
then select
Setup
. Select
Audio
in the left menu. Highlight the
Dolby Digital

instructions and select from the following options:
