From digital input, through

digital processing, to

amplification, maximum

signal quality is maintained

every step of the way.

* In addition to the six channels (Main L/R, Centre, Rear L/R, Rear Centre) there is a subwoofer output (hence 6.1-channel format compatibility) and two front

effect channels (a total of 9 DACs). The front effect channel signals, unique to Yamaha CINEMA DSP, are mixed with the main channel signals to achieve more

precise separation of dialogue, music and effects on the front sound stage and a superior sense of presence as compared to other systems.

are smaller (2/3 previous types), so

signal paths are shorter and there is

more space for the large power supply

components. Digital interference is

reduced and impedance is lower as well.

Brief Guide to Movie Sound Formats

Dolby Pro-Logic

Dolby Lab's basic 4-channel format, widely

used in ordinary theaters and for home

videos.

Dolby Pro Logic II

Improved version of Dolby Pro-Logic for

music and movies. With a more intelligent

matrix decoder, it is suitable for both stereo

and surround-encoded sources. It offers

"bass management" as well as the option of

incorporating "width," "dimension" and

"panorama" controls.

Dolby Digital

The most popular 5.1-channel home cinema

sound system. An improvement over Dolby

Pro-Logic in that it offers: 1) Full frequency

response in all channels (3Hz — 20kHz), 2)

discrete surround channels, and 3) a

separate track for bass only, called the Low

Frequency Effects channel.

Dolby Digital EX

Dolby's latest surround format, this is Dolby

Digital with an added centre rear channel.

The rear centre channel is actually matrixed

into the two rear channels, and is extracted

upon playback. (Formerly called Dolby

Digital Surround EX, or Dolby Digital Matrix

6.1.)

DTS Digital Surround

The basic DTS 5.1 channel sound format.

Uses a higher data rate than Dolby Digital.

Its extreme accuracy is due to a high-

signal-resolution analogue design in

conjunction with an ultra-precise digital

control circuit (Yamaha original YAC-520

LSI). The wide control range extends

from 0dB to 99dB, with narrow 0.5dB

steps throughout the entire range for

delicate control, even at low volumes.

DTS-ES Matrix 6.1

In this format, the back surround channel is

matrix encoded into the left and right

surround channels. For playback, the three

channels are separately decoded.

DTS-ES Discrete 6.1

DTS-ES uses its large bandwidth to provide

a fully discrete rear centre channel, as

opposed to a matrixed one.

DTS Neo:6

Provides 5.1 or 6.1 channels of matrix

decoding from stereo matrix material. Also

decodes Extended Surround matrix

soundtracks and has a Music mode to

expand stereo non-matrix recordings to 5.1

or 6.1 channels.
