Dolby Digital

Dolby Digital is a highly sophisticated and versatile audio encoding/decoding technology. Dolby Digital technology can transmit mono, stereo (two-channel), or up to 5.1-channel surround sound (discrete* multichannel audio).

In 5.1-channel surround sound, the three front channels (Left/Center/Right) deliver crisp, clean dialogue and accurate placement of on-screen sounds, while twin surround channels (Left Surround/Right Surround) wrap around the audience and immerse them in the action. The LFE (Low-Frequency Effects) channel delivers real impact for explosions and other effects that can, literally, be felt as well as heard.

The superior coding efficiency of Dolby Digital-and its ability to deliver high-quality discrete multichannel audio without compromising video quality has made it the designated audio standard for DVD worldwide.

*The sound information contained in each of the six available channels is distinct and independent. These six channels are described as a "5.1-channel" system, because there are five full-bandwidth channels with 3 Hz to 20 kHz frequency range for Front Left and Right, Center, and Surround, plus one "Low Frequency Effects" (LFE) subwoofer channel devoted to frequencies from 3 to 120 Hz.

Dolby Digital EX

Dolby Digital EX takes the Dolby Digital 5.1-channel setup one step further with an additional center surround channel (reproduced through one or two speakers) for extra dimensional detail and an enveloping surround sound effect.

Feature films originally released in Dolby Digital Surround EX (the cinema version) carry the encoded extra surround channel in their subsequent DVD releases, as well as onto 5.1-channel digital satellite and TV broadcasts. With this receiver, you can hear Surround EX soundtracks as they were meant to be heard, with the increased realism created by the extra surround channel.

Dolby Pro Logic II

Dolby® Pro Logic® II technology processes any high quality stereo (two-channel) movie and music audio into five playback channels of full-bandwidth surround sound. A matrix surround decoding technology, Dolby Pro Logic II detects the directional cues that occur naturally in stereo content and uses these elements to create a five-channel surround sound playback experience. Dolby Pro Logic II is fully compatible with all Dolby Pro Logic technologies. It provides optimal audio for playback in a 5.1- channel home theater system for the thousands of videocassettes and TV programs encoded in four-channel Dolby Surround (the encoding counterpart to Dolby Pro Logic's decoding technology). (Dolby Pro Logic II surround Movie mode)

Dolby Pro Logic II also enables video game consoles to encode five-channel surround sound information into a stereo signal with virtually no impact on the console's CPU, which means all this extra audio won't slow your game down. (Dolby Pro Logic II surround Game mode)

Dolby Pro Logic II can bring new life to your CD collection. Play your music through your home theater system, and you'll hear seamless, natural sound with new depth and detail. It's almost like hearing a newly remastered CD. (Dolby Pro Logic II surround Music mode)

Dolby Pro Logic IIx

Dolby Pro Logic IIx transforms any stereo or 5.1-channel signal into six- or seven-channel, full range surround sound, creating a seamless, natural surround soundfield that immerses you in the entertainment experience.

Three listening modes, Movie, Music or Game allow you to tailor the audio to meet the different needs of the programming. In Game mode, for instance, special effects signals are routed to the surround channels for fuller, dramatic impact. Music mode features three additional use controls:

•Dolby Center Width adjusts the balance of the main vocals in the center and front channels.

•Dolby Panorama creates a seamless, wraparound surround effect.

•Dolby Dimension lets you set a deeper or shallower surround soundfield.

DTS

DTS Digital Surround is the standard for providing 5.1 channels of discrete digital audio in consumer electronics products and software content.

DTS can contain a larger volume of data than Dolby Digital, and can reproduce high quality surround sound. They are the same as the Dolby Digital 5.1 channels, but it is a format that lowered the audio compression rate when recording digitally. Because of that, rich sound with high S/N can be reproduced. Moreover, an exact, magnificent surround sound with wide dynamic range and excelling in separation is a feature of DTS.

DTS has a ".1" or LFE channel.

The indication "LFE" appears in the display when a signal is being input for this channel.

DTS-ES

In the cinema, the center surround channel is not discrete, but is matrixed into the left surround (LS) and right surround (RS) channels. Embedded in the soundtrack print master, this matrixed channel works with all cinema digital sound formats. DTS calls this process Extended Surround, or "ES".

Neo:6

Neo:6 provides up to six full-band channels of matrix decoding from stereo matrix material. Users with 6.1 and 5.1 systems will derive six and five separate channels, respectively, corresponding to the standard home theater speaker layouts. (The ".1" subwoofer channel is generated by bass management in the receiver.)

Neo:6 provides optimum decoding of Extended Surround matrix soundtracks, and can also generate a center surround channel from 5.1 material.

Neo:6 technology allows various sound elements within a channel of channels to be steered separately, and in a way which follows the original presentation naturally.

Neo:6 offers a music mode that expands stereo non-matrix recordings into the five- or six-channel layout without diminishing the subtlety and integrity of the original stereo recording.
