control than up and down — except
Yamaha. We decided that controlling
the volume could be made both easier
and more accurate, and the result is the
Accurate Touch Volume Control. It lets
you make delicate adjustments within a
narrow range, yet enables you to move
to very high or low levels more quickly.

3/10 (G/B)

(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.

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.

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.

Dolby Pro-Logic

Dolby Lab’s basic 4-channel format, widely
used in ordinary theatres 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.

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.
