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 toYamaha 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.
䢇Dolby Pro-Logic
Dolby Lab’s basic 4-channel format, widely
used in ordinary theatres and for home
videos.
䢇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.
䢇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.
䢇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.)
䢇DTS Digital Surround
The basic DTS 5.1 channel sound format.
Uses a higher data rate than Dolby Digital.
䢇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.
䢇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.
䢇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.
Brief Guide to Movie Sound Formats

High Current Amplification Achieves Low Impedance/
High Current Power from Input to Output.
The Importance of High Current
Although power rating is often the first
thing customers look at in a receiver, high
power output does not necessarily mean
good sound. High current level is a much
more important factor. Yamaha receivers
has always had fairly high current levels,
but with the RX-V740RDS, we have further
improved this performance.
What It Does
In brief, Yamaha High Current
Amplification achieves low impedance,
high current power from input (power
supply circuit) to output (speaker
terminals). This drives the speakers much
more smoothly and dynamically, for better
sound from all sources, including 2-
channel audio.
Specific Improvements
The first problem to be overcome was the
difference in voltage that ordinary
receivers suffer between the power
supply and amplifier circuits, caused by
current fluctuations. This was solved by
using custom-made, high-grade block
electrolytic capacitors and a copper grip
for one-point grounding. Another current
drop is generally seen between the
amplifier circuit and the speaker
terminals, caused by the cables, speaker
output relays, copper circuit boards, and
so on. To increase current here, we used
an extra-large, low-impedance
transformer and gold-plated speaker
relay contacts.
6-Channel High Power,
Discrete Amplifier Configuration
The RX-V740RDS will deliver as much as
140W of power (DIN) 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 subwoofer.
High Dynamic Power Capability
The RX-V740RDS 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.
Linear Damping (Main L/R Channels)
Level variations due to high amp
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.
Anti-Resonance ToP-ART Base
Supporting the heavy heat sinks and
circuit board is Yamaha’s ToP-ART base,
which has exceptional anti-resonance and
damping characteristics. Beneath this
base is the bottom of power amplifier, part
of the heavy chassis which is also
The voltage (A) of Block Electrolytic Capacitors and voltage (B) of
Power Transistor Collector should be ideally at the same level. However,
when the current become large, there will be a big difference in the
level of each voltages.
Voltage level difference between A (power supply circuit) and B
(amplifier circuit). Voltage level difference between C (amplifier circuit output) and D (speaker terminals).
High Current Amplification
Conventional Amplifier High Current Amplification Conventional Amplifier
There is also a level difference between Output of the Power Amplifier
(C) and Speaker Terminals (D), which is caused by the copper of the PCB,
Speaker output relays, cables and so on, resulting in reduced sound

designed for maximum vibration
damping.
Anti-Resonance Aluminium-Extruded
Heat Sink
The large, anti-resonance, aluminium-
extruded heat sink is located on the base
frame with the power amplifier circuit
boards to prevent interference with the
preamplifier and digital processing
sections. The power block is equipped
with a fan, but it is only used for extreme
heat build-up and is not activated during
normal operation, preventing the
occurrence of even the slightest
unwanted noise.
Wide-Range Frequency Response for
DVD-Audio and SACD
With an extremely wide frequency range
of 10 to 100,000Hz, this receiver is
capable of delivering the full potential of
the new digital audio sources DVD-Audio
and SACD.
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.
Finest Parts Used Throughout
In order to realize the goals of massive
power and superlative sound quality,
Yamaha technicians completely re-
evaluated all the parts used in previous
receivers. As a result, many were
replaced with more expensive or custom-
designed units.
䢇Extra-Large Custom-Made Block
Electrolytic Capacitors
Developed specifically for the RX-
V740RDS, the 12,000µF/71V block
electrolytic capacitors use low-
magnification foil and are exceptionally
high quality.
䢇Direct Signal Path Speaker Relays with
Gold-Plated Crossover Connection and
Shielding
Speaker switching is accomplished by
relays right in front of the speaker
terminals, rather than at the switch
position. This results in a shorter signal
path and minimum output impedance.
䢇High Performance Myca Capacitors and
Film Capacitors
At this level of sound quality, even these
small parts make a difference. The high
precision FE mica and metallic mylar film
capacitors use polypropylene material
and are the highest performance types on
the market.
䢇Extra-Large Low-Impedance
Transformer
The large 4.8 kg low-impedance
transformer is an important factor in the
RX-V740RDS’s extremely stable power
supply.
䢇Thick PC Board Wiring with 1.6mmφ
Copper Jumper Cables
The audio signal is routed within the
amplifier through exceptionally thick,
top quality wire, ensuring that signal
purity is maintained.

the open feeling of large-scale, epic
motion pictures. The Sci-Fi is designed to
reproduce all the complex, dynamic
sounds of space/science fiction movies.
Adventure and General are also included.
Centre Graphic Equalizer
In addition to the many audio parameters
that can be adjusted, the RX-V740RDS
provides an even greater degree of sound
field control with the inclusion of a Centre

Quad-Field and Tri-Field
CINEMA DSP
Tri-Field CINEMA DSP projects three
sound fields into the home cinema: a
Presence sound field in the front and
two Surround sound fields in the left
rear and right rear, resulting in a
powerfully realistic three-dimensional
soundscape. And now Yamaha also
offers Quad-Field CINEMA DSP. It adds
an additional rear centre sound field to
the Tri-Field system, in order to enjoy
the new 6.1-channel formats, Dolby
Digital EX and DTS-ES.
CINEMA DSP Programmes
One of the main advantages of CINEMA
DSP is the large choice of sound field
programmes available. The basic
programme for movies is Enhanced,
which greatly improves the sound of the
surround fields. The "largest" of these
Going Beyond Conventional Multi-
Channel Systems
Conventional 5.1-channel/6.1-channel
audio reproduction systems base their
sound on Dolby Digital and DTS
decoding, using matrix and steering
technologies to create surround sound
effects. Yamaha CINEMA DSP is much
more advanced, actually creating richly
realized independent sound fields that
merge to envelop you in an unmatched
surround sound experience. With
dialogue, music and effects from the
presence (front), rear and rear sound
fields, you will hear sound with highly
accurate localization, smooth
movement, exceptional clarity and
richness, and startlingly realistic
presence. It will seem as if the walls of
your room have disappeared and you
are in the middle of your own immense
theatre!

Yamaha’s unique technology for the creation of sound fields is capable of
powerfully reproducing the three-dimensional environment that movie
sound engineers aim to convey, in any audio format from monaural to the latest 6.1-channel
digital surround. It is compatible with DVD and all other A/V sources.
