High sound quality circuit design based on the ToP-ART (Total Purity Audio Reproduction Technology) concept

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 this amplifiers’ rich audio reproduction with abundant musicality.

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.

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-S501 is 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.

Pure Direct Mode for Greater Sound Purity

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.

Continuously Variable Loudness Control

The A-S501 also features 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. The A-S501 have Gold-plated speaker terminals and RCA (CD, Phono) and coaxial terminals.

Digital Audio Input for TV and/or Blu-ray Player

The A-S501 is equipped for digital audio input with both optical and coaxial terminals. The optical is for receiving audio from a TV, and the coaxial for receiving audio from a Blu-ray player. The audio stays in the digital domain, giving you pure, pristine dynamic sound for all your entertainment sources, from sports and other programmes to movies and concerts.

Connection for YBA-11 Bluetooth Wireless Adapter

With the YBA-11, you’ll be able to stream music wirelessly from a Bluetooth capable mobile phone or a PC to the Network receiver. Thanks to the digital connection and aptX® audio coding algorithm, you’ll enjoy wireless music streaming with optimum sound quality. You can also conveniently power the YBA-11 via the DC-out connection on the rear panel of the amplifier.

Speaker A, B or A+B Selection and Speaker Terminals for Two Systems

You can connect two separate speaker systems in different rooms and switch between them, or have them both playing at the same time. There are four terminals, so by just pushing a button, you can switch speakers to match the sound source.
