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. 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.

Six mm thick top panel made of non-magnetic aluminium plate

The top panel and the front panel are made of aluminium, 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 7mm and the top panel was set at 6mm. This helps to realise an exceptionally natural, spacious sound by providing a highly rigid chassis structure, and at the same time, skillfully controlling the impact of vibration.

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 maximise 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 pre amp and power amp blocks

The amplifier circuit design features independent pre amp and power amp blocks, and perfect left-right symmetry. Separation of the pre amp, which handles low energy signals, from the power amp, 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 amp circuit adopts Yamaha’s own, uniquely developed 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.

All-stage balanced transmission

Features fully balanced signal transmission. Moreover, the control system circuits (volume, tone, etc.) of the pre amp feature totally balanced operation, realising ideal balance in all stages.

Direct drawing toroidal transformer for complete elimination of signal transmission loss

The cabling of the power transformer adopts an ingenious method in order to significantly reduce impedance. The winding of the transformer itself is directly connected to the terminal with a screw, unlike with conventional cabling. This enables a power supply which thoroughly limits connection loss and energy loss caused by soldering. The toroidal transformer was selected with top priority on sound quality, contributing superior strength, as well as a profoundly natural and spacious sound.

Exceptionally low impedance through secure screw connections

In order to completely eliminate signal energy loss, important parts of even the circuits employ screw connections. In addition to wiring of the block capacitor of the power unit—which is the real heart of the amplifier and as such requires high power—screw connections were adopted for all crucial spots of signal transmission, including the connection of the pre amp circuit with the power amp circuit, and the cabling to the speaker terminals from the output stage of the power amp.

Superior quality electronic volume control for optimum sound

Yamaha utilized a high quality digital volume control specially designed by New Japan Radio Co., Ltd., which consists only of ladder-type resistance, removing the impact of slew-rate decline or colouring of the sound, delivering higher purity in the sound, and excellent, fast response to large volume changes and steep transients.

Exquisite, large level meters reflect the dynamics in the music

Features large level meters on the front panel, giving a direct visual sense of the dynamics and pulse of the music. These beautiful meters are softly illuminated by LED, lending a warm, lamplight look. The meter indicators can, in addition to the VU display, be switched to peak display, and can be selected according to the user’s preference.

Original speaker terminals for high sound quality, as well as beauty and ease of use

The speaker terminals are the final link in the audio chain of this amplifier, and have also been designed with meticulous obsession. They are screw-type terminals with large handles featuring an original design, and have been crafted by cutting pure brass to enable a secure connection with no reduction in sound quality.
