High Quality Sound

Continuously Variable Loudness Control

The A-S701/S501/S301 also feature a new analogue

loudness control on the front panel that uses electronic

volume for higher sound quality, which lets you adjust

the loudness effect as desired. Separate from the overall

volume, this controls the balance of the low- and high-

frequency sounds, providing full tonal range at any volume

level, compensating for the natural loss in the human ear of high and low

frequencies at soft levels.

Gold-plated Terminals

Gold-plated terminals ensure a high quality

connection that prevents signal loss. Both the A-S701

and A-S501 have gold-plated speaker terminals and

input terminals*.

* A-S501 CD, Phono and Coaxial input terminals only.

CD Direct Amplification (A-S701) and Pure Direct

Mode for Greater Sound Purity

With a straight connection to the CD input, CD Direct

Amplification maximises CD source S/N ratio. Additionally,

engaging the Pure Direct mode causes the music signals

to travel the shortest possible circuit route, bypassing

the buffer amp and the tone, loudness and balance controls to virtually

eliminate any signal degradation for the purest sound quality.

ToP-ART Design and ART Base Ensure Optimum Sound When

processing and transmission of the audio signal is simple and

direct there is less chance of it being affected by noise and

distortion. Yamaha’s amplifier design technology called ToP-ART

features an I/O (input to output) Direct Symmetrical Design, with

left and right channels organised in a straight, symmetrical layout

for highest signal purity. In addition, the ART (Anti-Resonance

and Tough) Base bottom chassis and a solid centre bar provide

high-rigidity support and vibration damping. These Yamaha design

innovations contribute to these amplifiers’ rich audio reproduction

with abundant musicality.

High sound quality circuit design based on

the ToP-ART (Total Purity Audio Reproduction

Technology) concept

Created by Yamaha's Rich Experience and Tradition,

and High Technological Expertise

Yamaha, with a long history of over 125 years as a musical

instrument maker, also has a high reputation for HiFi components.

The A-S701/S501/S301 are created by taking advantage of this rich

experience and high technological expertise. Based on the concept

of “Natural Sound”, for reproducing all music as it really sounds,

and built with scrupulous care from circuit design to basic sound

production, even though an entry model it reproduces high sound

quality and musically rich sound.

High Quality Parts for Outstanding Audio Performance

Custom-made power transformer, custom-made block capacitors,

two direct signal path speaker relays, one-point grounding system,

aluminium-extruded heat sinks and other top-quality parts effortlessly

handle demanding audio signal conditions. The quality of each

individual part, as well as how they

work together, basically determines

the sound quality of any component.

Yamaha uses only very high quality

parts, carefully selected and tested.
