Yamaha

RX-V740RDS 580
Can respected amplifier manufacturer Yamaha come up with the goods once again with its RX-V740RDS?
amaha has a reputation as one of the leaders in home cinema amplification. Its range caters for just about every scenario and budget, and boasts some of the most flexible models around. The RX-V740RDS surround sound amp is more correctly described as a surround sound receiver, which, as its name suggests, incorporates an RDS-enabled tuner for radio fans. Beneath the stylish titanium-finish box there are six full channels of amplification (rated at 90W each) and the amp can handle the 6.1-channel formats Dolby Digital EX, DTS-ES and DTS-ES discrete. Regular Dolby Digital and DTS 5.1 formats are also accommodated, and Dolby Pro-Logic II and DTS Neo:6 convert stereo sources into near-digital surround sound. Yamaha is known for adding its own processing modes to its amp, and the RX-V7040 RDS has 44 home cinema digital signal processing (DSP) modes, as well as a handful of Digital Sound Processing modes for hi-fi listening in surround sound. Most add a fun element, and are intended to simulate the acoustics of a movie theatre. Youll either love or loath the style of the Yamaha, with its functional-looking front panel. Despite its utilitarian looks and high button count, however, its reasonably intuitive to operate, and the plentiful TEST SCENE

FINDING NEMO

buttons mean youre not totally reliant on the remote. Theres also a set of inputs on the front panel for easy connection of occasional sources like a camcorder or games console, along with S-video and composite video sockets, stereo analogue audio and optical digital audio inputs. Around the back theres an impressive array of audio and video sockets and speaker connections. The Yamaha can even drive an additional set of stereo speakers for listening to sources in another room. And an arrangement of audio inputs means that the amp can easily control all your sources.
NICE TO SEE YOU, TO SEE YOU, NICE!
Bruces attack sequence is a good demonstration of the Yamahas strengths, with integrated surround sound effects and dialogue, and explosive action effects

Nautical but nice

Impressive connectivity and format handling counts for nothing if multichannel performance isnt up to scratch, but the Yamaha doesnt disappoint. It has a warm sound that immediately draws you into the movie environment like the underwater setting of Finding Nemo and expertly places subtle effects all around the room. It has a comfy sound thats easy on the ear, and it easily drove our high-end speaker package as well as more compact sub/sat speakers. Theres plenty of power to cope with dramatic moments like Finding Nemos shark attack scene, while the exploding minefield sequence is also a good demonstration of the Yamahas skills. Yamahas hi-fi roots are clearly in evidence, as the RX-V740RDS happily doubles as a hi-fi amp. Music is controlled, rich and evocative, and the amp can deliver party volume levels without hardening up. While there are plenty of amps with a similar specification at this price, the Yamaha RX-V740RDS combines a rich and involving sonic signature with a host of features to make it an impressive all-rounder. Trying to find Nemo? Youve found him! WHC

* 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.
(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. Accurate Touch Volume Control No one expects more from a volume
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.
Its extreme accuracy is due to a highsignal-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.
Brief Guide to Movie Sound Formats
Dolby Pro-Logic Dolby Labs 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.

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 2channel 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 musics 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 amplifiers 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 Yamahas 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

High Current Amplification Principle
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. 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 quality.

designed for maximum vibration damping. Anti-Resonance Aluminium-Extruded Heat Sink The large, anti-resonance, aluminiumextruded 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 reevaluated all the parts used in previous receivers. As a result, many were replaced with more expensive or customdesigned units.

Extra-Large Custom-Made Block Electrolytic Capacitors Developed specifically for the RXV740RDS, the 12,000F/71V block electrolytic capacitors use lowmagnification foil and are exceptionally high quality. 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. 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.

Extra-Large Low-Impedance Transformer The large 4.8 kg low-impedance transformer is an important factor in the RX-V740RDSs extremely stable power supply. Thick PC Board Wiring with 1.6mm Copper Jumper Cables The audio signal is routed within the amplifier through exceptionally thick, top quality wire, ensuring that signal purity is maintained.

No Other Surround Sound System Can Match for Rich, Detailed, Realistic Sound.
Going Beyond Conventional MultiChannel 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!
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

sound fields is Spectacle, which recreates 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 Graphic Equalizer. This lets you finely tune the overall balance of the sound field to achieve the optimal imaging for movie sound.
