Digital 5.1
Dolby Digital 5.1 gives you 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
® Receiver
is connected to a compatible Dolby Digital 5.1 channel A/V receiver and 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 are broadcast using Dolby Digital 5.1 for DIRECTV
®
programming.
Programs broadcast using this high-quality audio standard are indicated by the words Dolby
Digital in the program description in the Channel Banner (see page 23) and the Guide (see
page 24).
