Yamaha A-S3000 2x 130W Natural Sound Integrated Amplifier, Silver

A piano comes into this world through the perfect synergy of advanced technical skill and artistry. Such a piano can create sound that truly reflects the player's feelings. The final stage in piano production is called "voicing." This breathes life into the instrument and truly makes it musical. To accomplish this, highly skilled experts focus their concentration and sensitivity completely on each note and delicately adjust the hardness and resilience of the hammers that strike the strings, establishing the perfect, consistent sound for the entire instrument and determining its tonal personality.

Profoundly accurate sound with the full expressive power of the music. Exceptional sonic purity, elimination of signal loss-in an exquisite, elegant design. The supreme culmination of the Yamaha line-the A-S3000.

Rigid Streamlined Construction - Provides Strict Anti-vibration Protection and Enables Shortest Cabling Routes
The A-S3000 has adopted a newly designed highly rigid double structure construction in order to achieve profoundly pure and accurate audio amplification. The bottom chassis and insulator ward off external vibration and provide each circuit board a floating structure supported by an independent inner frame, thoroughly eliminating the impact of vibration. And the power source unit, which consists of a power transformer and capacitors, which are major sources of internal vibration, is fixed firmly with a three-dimensional structured inner frame and is supported solidly by the front panel and the rear panel. The power amplifier circuit board and the weighty heat sink are attached to the left and right inner frames.

The power supply unit and amplifier circuits are thus structurally isolated, achieving an ideal chassis structure which thoroughly blocks the transmission of vibration. Moreover, the inner frame that supports the power transformer is shaped with ample space below it, allowing passage of the wiring to each circuit over the shortest possible route. The newly developed chassis with this innovative structure helps to minimize the length of the signal paths and achieve low impedance, as well as providing high rigidity and anti-vibration benefits. The result is a dramatic reduction in signal loss, for remarkably pure audio amplification.

Large Toroidal Transformer, Solidly Mounted with Independent Three-dimensional Inner Frame
An independent three-dimensional inner frame has been employed in order to provide a more solid mount for the large toroidal transformer, which is installed in the center of the A-S3000, considering the ideal weight balance. The completely copper-plated inner frame has a structure which integrates the front-back and left-right frames with a convex-shaped highly rigid main frame as its base, reducing vibration coming from all directions.

For the base, to which the power transformer is installed on the inner frame, brass was selected by strictest examining the particular sonic properties of various materials by exhaustive listening tests. This material effectively reduces vibration caused by the power transformer, helping to create sound of greater clarity and spaciousness.

Comprehensive Low Impedance Design, Shortened Signal Paths and Copper-plated Chassis
In order to achieve the absolute purest signal transmission, capable of communicating even the most subtle nuances of the music and its powerful dynamism-for example, reproducing powerful, agile low frequencies and portraying all the emotional nuances of the human voice-we've methodically pursued low impedance throughout the A-S3000. Using a double construction design creates space for cables under the bottom of the chassis, enabling the shortest cable path for the supply of power from the transformer to the power stage and for the audio signal transmission path.

This helps to eliminate signal transmission loss and to smoothly supply power, even during high-volume transients and allows more direct audio reproduction without even the slightest adverse effect on the music. Also, the three-dimensional inner frame to which the power transformer is mounted is copper-plated. Extremely low impedance is assured by lowering the ground potential. This sharply lowers the impact of noise and delivers a profound and richly emotional sound-one that perfectly communicates all the original expression of the artist.

1/4 Inch Thick Top Panel Made of Non-magnetic Aluminum Plate
The top panel and the front panel are made of aluminum, a non-magnetic material, in order to eliminate any adverse effect on the audio signals. In the course of strictest examination of the sound quality, the front panel thickness was set at 0.28" and the top panel was set at 0.24" . This helps to realize an exceptionally natural, spacious sound by providing a highly rigid chassis structure and at the same time, skillfully controlling the impact of vibration.

Moreover, heat dissipation openings on the top panel were formed by high precision cutting from both sides-front and back-of the panel and finished with thorough scrupulous attention to every detail. Stylish slits in the center, matching the companion CD-S3000 and its design, strongly emphasize the powerful power source unit inside by having the same width as the power transformer.

Insulators Allow Use of Spikes or Pads
The insulators are crucial parts that block outside vibrations. They adopt Yamaha' s original metal legs in order to maximize vibration control performance. The user can select point installation by applying the supplied spikes or plane insulation with the supplied pads and use these combined with an interlocking rack if desired.

Left-right Symmetrical Design for Independent Preamplifier and Power Amplifier Blocks
The amplifier circuit design features independent preamplifier and power amplifier blocks and perfect left-right symmetry. Separation of the preamplifier, which handles low energy signals, from the power amplifier, which handles high-energy amplified signals, greatly reduces sound deterioration caused by mutual interference. Moreover, the left-right symmetrical design, which keeps the left and right power stages completely separate, ensures greater channel separation and enhances clarity of the stereo image.

Floating and Balanced Power Amplifier with MOSFETs
The basic design of the power amplifier circuit adopts Yamaha's proprietary Floating and Balanced Power Amplifier technology. Adopting output elements with the same polarity on the plus and minus sides of the output stage and also completely separating the NFB (Negative Feedback) circuit and power supply into a total of four plus and minus sides of the left and right channels, results in thoroughly symmetric push-pull operation of the output stage. Completely floating the entire power amplifier circuit from the ground removes any negative impact of minute voltage fluctuations or ground noise.

Moreover, the output elements are comprised of MOSFETs, which provide a warm and natural sonic character. The use of MOSFETs, which have the same polarity on the plus and minus sides, further evolves the ideal of a complete symmetrical design, to eliminate sound quality variations due to difference in polarity-a major distinguishing characteristic of the Floating and Balanced Power Amplifier-resulting in sound with a superior signal-to-noise ratio and a superbly well-defined sound field.
