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.

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.
