The DIRECTV ® HD Receiver will be the focal center of your home entertainment system comprising a
variety of components, such as TV, DVD, VCR, etc. and external audio systems. Since digital programs
being broadcast contain digital-quality audio, you can create a home theater by sending audio signals
from the DIRECTV HD Receiver to your audio system externally. HD digital signals use the Dolby
Digital ® audio encoding system - the same digital sound used in many movie theaters, on DVDs, and
in many home theater systems.
When you tune to a channel, the DIRECTV HD Receiver can send signals either to a Dolby Digital
decoder/receiver or to a PCM (normal digital) decoder. (* Refer to Section 3-7 Connection for Audio
for making the required external connections to your system)

response audio channels (three in left, center, and right, two in rear left
and right,) and one low frequency effect for a sound you can feel.
