Dolby Digital

Dolby Digital is an encoding, transmission and decoding standard for stereo up to 5.1 channels of digital audio. It is available only with digital input sources encoded with Dolby Digital data. It provides up to five separate main audio channels and a special dedicated low-frequency effects channel and delivers high-quality multichannel audio without compromising video performance. Dolby Digital is the world wide audio standard for DVD-Video.

Dolby Digital EX

Available when the receiver is configured for 6.1 channel operation. Dolby Digital EX introduces a centre rear channel to the 5.1 playback format.This additional channel provides increased spatiality and realism for audio effects that pan from front to back, as well as enhanced localization of surround channels that originate from directly behind the listener.

When used with movies or other programs that have special encoding, Dolby Digital EX reproduces specially encoded soundtracks so that a full 6.1 soundfield is available. When the receiver is set for 6.1 operation and a Dolby Digital signal is present, the EX mode is automatically selected.

Dolby Pro Logic II x

Processes stereo movie and music content into six independent playback channels of full bandwith surround sound.

Dolby Pro Logic II x Movie is optimized for movie soundtracks, especially those recorded in Dolby Surround.The channel separation and movement of surround effects is comparable to Dolby Digital EX.

Dolby Pro Logic II x Music is optimized for music.The surround effect is more enveloping than Pro Logic II Movie.

DTS

DTS Digital Surround is a 5.1-channel surround sound format, similar to Dolby Digital. DTS (Digital Theater System) features up to five discrete (independent) channels (front centre, front left, front right, surround left, surround right) of full frequency sound plus a sixth channel for low frequency effects (LFE).The LFE signal is usually reserved for the subwoofer or speakers capable of reproducing low frequency ranges.

DTS ES

DTS Extended Surround is a 6.1-channel surround sound format that extends the 5.1-channel surround sound format with one additional speaker located in the back of the listener (i.e., back surround channel). DTS ES comes in two versions: DTS Extended Surround Matrix and DTS Extended Surround Discrete 6.1.

DTS 96/24

DTS 96/24 offers high-quality 5.1-channel sound playback on DVD-Video and is fully backward- compatible with all DTS decoders. '96' refers to a 96kHz sampling rate (compared to typical 48kHz sampling rate.) '24' refers to 24-bit word length.

DTS Neo:6

DTS Neo:6 provides up to six channels of matrix decoding from stereo matrix material. Neo:6 Cinema is suitable for movies. Neo:6 Cinema delivers good channel separation for movie soundtracks.

Neo:6 Music is suitable for music. It plays the stereo source more through the front left/right speakers, and generates a natural, ambient surround and centre sound.
