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.
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.

videos.
discrete surround channels, and 3) a
separate track for bass only, called the Low
Frequency Effects channel.
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.
ⅷ Dolby Pro Logic II
ⅷ Dolby Digital EX
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'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.)
ⅷ 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.
ⅷ 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.

High Dynamic Power Capability
Although power rating is often the first
thing customers look at in a amplifier, high
power output does not necessarily mean
good sound. High current level is a much
more important factor. Yamaha amplifiers
has always had fairly high current levels,
but with the DSP-AX640SE, we have
further improved this performance.
The DSP-AX640SE is capable of delivering
large amounts of reserve power for
accurate reproduction of the high energy
peaks that are especially prevalent in
digital audio sources. This emphasizes the
music’s dynamic qualities and provides a
sharper sound image.

sound from all sources, including 2-
channel audio.
impedance tend to reduce an amplifier’s
damping factor, and frequency variations
cause it to fluctuate. This circuit cancels
the effect of these variations, maintaining a
high, stable damping factor, for superior
articulation of all sounds and better
frequency response.
6-Channel High Power,
Discrete Amplifier Configuration
The DSP-AX640SE will deliver as much as
85W of power to each of six channels
(two main, two rear, one centre and one
rear centre). This is more than enough to
fill even the largest rooms with vibrant
music and Richter-scale sound effects. 6-
4 mixdown is also provided, for enjoying
6-channel input sources from four or five
speakers you already have on hand with
or without a subwoofer.
Anti-Resonance ToP-ART Base
Specific Improvements
Supporting the heavy heat sinks and circuit
board is Yamaha’s ToP-ART base, which
has exceptional anti-resonance and
The first problem to be overcome was the
difference in voltage that ordinary
amplifiers suffer between the power
supply and amplifier circuits, caused by
damping characteristics. Beneath this base
is the bottom of power amplifier, part of the

There is also a level difference between Output of the Power Amplifier

Optimum Space Utilization
The use of highly integrated LSIs allows
an interior design that maximizes power
and sound quality by positioning all the
digital processors and related circuitry in
one small area. This leaves most of the
space open for the power amplifier
components: transformers, capacitors,
heat sink and so on. This means that
these parts can be much larger than usual
for greater power, that they can be
separated for minimum chance of
interference, and that circuits can be
arranged in straight lines for maximum
signal purity. For example, the tone control
circuit layout is straighter and shorter than
ever.
