Surround sound formats

Below is a brief description of the main surround sound
formats you'll find on DVDs, satellite, cable and
terrestrial broadcasts, and video cassettes.

Dolby

The Dolby technologies are explained below. See
www.dolby.com for more detailed information.
Dolby Digital
Dolby Digital is a multichannel digital audio coding
system widely used in cinemas, and in the home for DVD
and digital broadcast soundtracks. It can deliver up to six
discrete audio channels, comprising five full range
channels and a special LFE (low frequency effects)
channel used mainly for deep, rumbling sound effects;
hence the term "5.1-channel" Dolby Digital.
In addition to the format features above, Dolby Digital
decoders offer downmixing for compatibility with mono,
stereo and Dolby Pro Logic audio from a number of bit
rates and channels. Another feature, called Dialog
Normalization, attenuates programs based on the
average level of dialog in a program relative to its peak
level (also known as Dialnorm) in order to achieve
uniform playback level.
Action
Check that the antenna cable is attached securely.
Check that the 8 pin mini DIN cable and AC Adapter are
attached securely.
Check for antenna obstructions and reposition the
SIRIUS antenna to get better signal reception. Use the
Antenna Aiming option to optimize the antenna position.

Dolby Digital Surround EX
Dolby Digital Surround EX (the EX stands for EXtended)
is an extension of Dolby Digital encoding whereby a
surround back channel is matrixed into the surround left/
right channels for 6.1 channel playback. This allows for
compatibility with Dolby Digital 5.1 channel decoding, as
well as for decoding using Dolby Digital EX.
Dolby Pro Logic IIx and Dolby Surround
Dolby Pro Logic IIx is an improved version of the Dolby
Pro Logic II (and Dolby Pro Logic) decoding system. Using
the innovative "steering logic" circuit, this system
extracts surround sound from sources as follows:
• Dolby Pro Logic – 4.1 channel sound (mono
surround) from any stereo source
• Dolby Pro Logic II – 5.1 channel sound (stereo
surround) from any stereo source
• Dolby Pro Logic IIx – 6.1 or 7.1 channel sound
(stereo surround and surround back) from two
channel or 5.1 (and 6.1) channel sources
With two channel sources, the ".1" subwoofer channel is
generated by bass management in the receiver.
Dolby Surround is an encoding system which embeds
surround sound information within a stereo soundtrack,
which a Dolby Pro Logic decoder can then use for
enhanced surround listening with greater sound detail.
