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.
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.
Pure Direct Mode for Greater Sound Purity
Continuously Variable Loudness Control
The A-S501 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 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.
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.
A terminal for connecting a subwoofer is provided, allowing you to increase the bass output of your system for a more powerful sound with better overall sound quality.
Phono MM Terminal
You can connect a turntable with an MM phono cartridge to play vinyl records. This lets you enjoy not only CDs, but also analogue record sound from an amp with the latest digital/analogue technology.
Simple yet Sophisticated Design
Remote Control with Clean, Simple Design
Rotary Encoder Input Selector with LEDs
The rotary encoder makes it quick and easy to select input sources. The luxury hairline finish material offers a nice tactile feeling. LEDs clearly show which source is selected, so you can easily switch sources even in a dark room.
