GLOSSARY

■Dolby Surround

Dolby Surround uses four discrete channels and five speakers to reproduce realistic and dynamic sound effects: two main channels (left and right), a center channel for dialog, and a rear channel for special sound effects. The rear channel reproduces sound within a narrow frequency range. Most video tapes and laser discs include Dolby Surround encoding, as do many TV and cable broadcasts. The Dolby Pro Logic decoder built into this unit employs a digital signal processing system that stabilizes each channel for even more accurate sound positioning than is available with standard analog processors.

■Dolby Digital

Dolby Digital is a digital surround sound system that provides completely independent multi-channel audio to you. Dolby Digital provides five full-range channels in what is sometimes referred to as a “3/2” configuration: three front channels (left, center and right), and two surround channels. A sixth bass-only effect channel is also provided for output of LFE (low frequency effect), or low bass effects that are independent of other channels. (This is called the “LFE channel”.) This channel is counted as 0.1, thus giving rise to the term 5.1 channels in total.

The wide dynamic range of sound reproduced by the five full-range channels and precise sound orientation by digital sound processing provides listeners with excitement and realism that have never been experienced before.

■DTS (Digital Theater System) Digital Surround

DTS was developed to replace analog soundtracks of movies with six discrete channels of digital soundtracks, and it is now installed in many theaters around the world. The DTS digital playback system changed the way we experienced movies in theaters with six discrete channels of superb digital audio.

DTS technology, through intense research and development has made it possible to deliver similar encode/decode discrete technology to home audio surround-sound entertainment.

DTS Digital Surround is an encode/decode system which delivers six channels of master-quality, 20-bit audio; technically, it is 5.1 channels, which means 5 full-range (left, center, right and two surround) channels, plus a subwoofer (LFE) channel (as “0.1”). It is compatible with the 5.1 speaker configurations that are currently available for home theater systems.

■CINEMA DSP CINEMA DSP

The Dolby Surround and Dolby Digital sound and DTS systems show their full ability in a large movie theater, because movie sounds are originally designed to be reproduced in a large movie theater that uses a multitude of speakers. Trying to create a sound environment similar to that of a movie theater in your home is difficult because of the room size, material inside the walls, the number of speakers, and so on. In other words, your listening room is very different from a movie theater.

However, YAMAHA DSP technology allows you to create nearly the same sound experience as that of a large movie theater in your home by compensating for the lack of presence and dynamics in the listening room with original digital sound fields combined with Dolby Surround, Dolby Digital or DTS Digital Surround sounds.

The YAMAHA “CINEMA DSP” logo indicates those programs that are created by the combination of YAMAHA DSP technology and Dolby Surround, Dolby Digital or DTS.

■LFE 0.1 Channel

This channel is for reproduction of low bass signals. The frequency range for this channel is 20 Hz to 120 Hz. This channel is called the channel 0.1 because it only reproduces a low frequency range compared to the full-range from

20 Hz to 20 kHz that is reproduced by the 5 channels in a Dolby Digital or DTS 5.1 channel system.

■S VIDEO Signal

The S VIDEO signal is separated and transmitted as the Y signal which indicates the luminance and the C signal which indicates the chroma of the video signal (composite signal). Using the S VIDEO terminal eliminates video signal transmission loss and allows recording and playback of even more beautiful images.
