2 Press and hold INPUT SELECTOR then press  STANDBY/ON on the display unit.

The next time you switch on, all the system settings should be reset.

Installation and maintenance

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

The Dolby technologies are explained below. See www.dolby.com for more detailed information.

Hints on installation

En

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 highdefinition 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 nextgeneration A/V receivers but remains fully compatible with all current A/

V receivers.

Dolby Digital Plus delivers multi-channel audio programs of up to 7.1 channels (*) and supports multiple programs in a single encoded bitstream with the maximum bit rate potential of up to 6 Mbps and the maximum bit rate performance of up to 3 Mbps on HD DVD and 1.7

Mbps on Blu-ray Disc, and it outputs Dolby Digital bitstreams for playback on existing Dolby Digital systems. Dolby Digital Plus can accurately reproduce the sound originally intended by directors and producers.

It also features multi-channel sound with discrete channel output, interactive mixing and streaming capability in advanced systems.

Supported by High-Definition Media Interface (HDMI), a single-cable digital connection is possible for high-definition audio and video.

Dolby TrueHD

Dolby TrueHD is the next-generation lossless encoding technology developed for high-definition optical discs in the upcoming era. Dolby

TrueHD delivers tantalizing sound that is bit-for-bit identical to the studio master, unlocking the true high-definition entertainment experience on high-definition optical discs in the next generation. When coupled with high-definition video, Dolby TrueHD offers an unprecedented home theater experience with stunning sound and high-definition picture.

It supports bit rates of up to 18 Mbps and records up to 8 full-range channels (*) individually with 24-bit/96 kHz audio. It also features extensive metadata including dialogue normalization and dynamic range control. Supported by High-Definition Media Interface (HDMI), a single-cable digital connection is possible for high-definition audio and video.

DTS 96/24

DTS 96/24 is an extension of the original DTS Digital Surround which offers high quality 96 kHz/24-bit audio using a DTS 96/24 decoder. This format is also fully backward compatible with all existing decoders. This means that DVD players can play this software using a conventional DTS

5.1 channel decoder.

DTS-EXPRESS

DTS-EXPRESS is a low-bitrate encoding technology supporting up to 5.1 channels with fixed data transfer rates. This format is incorporated with sub audio on HD DVD and secondary audio on Blu-ray Disc while boasting the potential applicability to upcoming broadcasts and memory audio contents.

DTS-HD Master Audio

DTS-HD Master Audio is a technology that delivers master audio sources recorded in a professional studio to listeners without any loss of data, preserving audio quality. DTS-HD Master Audio adopts variable data transfer rates, facilitating data transfer to the maximum rate of 24.5

Mbps in the Blu-ray disc format, 18.0 Mbps in the HD-DVD format, which by far exceeds that of a standard DVD. These high data transfer rates enable lossless transmission of 96 kHz/24-bit 7.1-channel audio sources without deteriorating the quality of the original sound. DTS-HD Master

Audio is an irreplaceable technology that can reproduce sound faithfully as intended by the creator of music or movies.

DTS Digital Surround

DTS Digital Surround is a 5.1-channel audio coding system from DTS

Inc. now widely used for DVD-Video, DVD-Audio, 5.1 music discs, digital broadcasts, and video games. It can deliver up to six discrete audio channels, comprising five full range channels, including an LFE channel. Higher sound quality is achieved through the use of a low compression rate, and high rates of transmittance during playback.

DTS-ES

DTS-ES (the ES stands for Extended Surround) is a decoder that is capable of decoding both DTS-ES Discrete 6.1 and DTS-ES Matrix 6.1 encoded sources. DTS-ES Discrete 6.1 gives ‘true’ 6.1 channel sound, with a completely separate (discrete) surround back channel. DTS-ES

Matrix 6.1 has a surround back channel matrixed into the surround left/ right channels. Both sources are also compatible with a conventional

DTS 5.1 channel decoder.

DTS Neo:6

DTS Neo:6 can generate 6.1 channel surround sound from any matrixed stereo source (such as video or TV) and from 5.1 channel sources. It uses both the channel information already encoded into the source, as well as its own processing to determine channel localization (with two channel sources, the “.1” subwoofer channel is generated by bass management in the receiver). Two modes (Cinema and Music) are available using DTS Neo:6 with two channel sources.
