Digital
The recommended audio format for HDTV is Dolby* Digital.
Your DIRECTV Plus HD DVR is capable of reproducing 5.1-encoded audio: five 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. The audio signals are broken into left-front, center, right-
front, left-rear, right-rear and low-frequency channels. The result, when your DIRECTV Plus HD DVR 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 15) and Guide (see page 17).
To change the Digital Audio format, press MENU, select Settings, then select Setup. Select Audio in the
left menu. Highlight the Dolby Digital tab and press SELECT, then follow the onscreen instructions and
select from the following options:
4 On: Turns on Dolby Digital audio output. (Note: True Dolby Digital is only available via HDMI or
optical outputs.
4 Off: Select this option to turn off Dolby Digital Audio output.
