Installation and maintenance
Hints on installation
We want you to enjoy using this system for years to come,
so please bear in mind the following points when
choosing a location:
Do...
Use in a well-ventilated room.
Place on a solid, flat, level surface, such as a table, shelf or
stereo rack
.
Don’t...
Use in a place exposed to high temperatures or humidity,
including near radiators and other heat-generating
appliances.
Place on a window sill or other place where the system will
be exposed to direct sunlight.
Use in an excessively dusty or damp environment.
Place directly on top of an amplifier, or other component in
your stereo system that becomes hot in use.
Use near a television or monitor as you may experience
interference — especially if the television uses an indoor
antenna.
Use in a kitchen or other room where the system may be
exposed to smoke or steam.
Use on a thick rug or carpet, or cover with cloth — this may
prevent proper cooling of the system unit.
Place on an unstable surface, or one that is not large enough
to support all four of the system unit’s feet.
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.
Dolby Pro Logic II 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
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.
Dolby Digital Plus
Dolby Digital Plus is the next-generation audio technology
for all high-definition programming and media. It combines
the efficiency to meet future broadcast demands with the
power and flexibility to realize the full audio potential
expected in the upcoming high-definition era. Built on Dolby
Digital, the multi-channel audio standard for DVD and HD
broadcasts worldwide, Dolby Digital Plus was designed for
the next-generation A/V receivers but remains fully
compatible with all current A/V receivers.
