Yamaha A-S501 HiFi Stereo Amplifier Black

Impressive Sound Quality with a Variety of Features and an Elegant Look!

Excellent Circuit Design Based on the ToP-ART Concept for Supreme Sound Quality

The ToP-ART concept (Total Purity Audio Reproduction Technology) guarantees excellent sound in combination with the ART Base. Only when both the processing and transmission of audio signals are designed to be simple and direct is the influence of noise and distortion minimized. Yamaha's technology for this amplifier design is called ToP-ART. It features a fully symmetrical structure from input to output, with left and right channels processed via the shortest possible signal paths. This ensures outstanding sound with uncolored clarity. The ART (Anti-Resonance and Tough) Base housing bottom and the solid center rail provide additional stability and dampen vibrations. These Yamaha design innovations contribute further to excellent audio playback with outstanding musicality.

High-Quality Components for Outstanding Sound Quality

The quality of individual parts and their interaction are crucial for the sound of any component. That’s why Yamaha uses only high-quality components that are carefully selected and tested. With the A-S501, excellent signal reproduction is guaranteed even under demanding conditions – the power transformer and blocking capacitors are custom-made, the speaker relays have a direct signal path, plus there is single-point grounding and extruded aluminum heat sinks.

Crafted with Yamaha’s Unique Experience, Tradition, and Technical Expertise

Yamaha not only has over 125 years of tradition in instrument making but also an excellent reputation for its HiFi components. The development of the A-S501 fully leveraged this long-standing experience and technical expertise. Based on the "Natural Sound" concept, music is reproduced as it truly sounds. Moreover, the amplifier was built with utmost care from signal paths to sound generation – even as an entry-level model, it offers excellent sound quality and unique musicality.

Pure Direct Mode for Uncolored, Pure Sound

When Pure Direct mode is activated, the signal bypasses the circuits for bass and treble control, balance, and amplifier buffer. This improves sound quality without affecting maximum output power. Shortening the signal path enhances acoustic purity and allows reproduction of even the finest musical nuances.

Continuously Adjustable Loudness

The A-S501 features a new analog loudness control located on the front panel. It uses electronic volume control for the highest sound quality, allowing the loudness effect to be adjusted freely. Separate from the normal volume control, it can influence the balance between treble and bass. This makes the full tonal range available and compensates for the natural hearing loss of high and low frequencies at low volume levels.

Gold-Plated Connections

Gold-plated connections provide a particularly high-quality connection that prevents signal loss. The A-S501 features gold-plated speaker terminals and RCA (CD, Phono) and coaxial connectors.

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

The A-S501 has both optical and coaxial digital inputs. The optical input is for TV audio, the coaxial for Blu-ray player audio. The signal remains fully digital throughout, ensuring pure, dynamic sound from all sources – from sports and other TV programs to movies and concert recordings.

Connection for a YBA-11 Bluetooth Wireless Adapter

With the YBA-11, you can stream music wirelessly from Bluetooth®-compatible smartphones, tablets, or PCs. Thanks to digital connection and the aptX algorithm, you enjoy music streaming in the best sound quality. The YBA-11 can be conveniently powered via the DC output on the back of the amplifier.

Connections for Two Speaker Systems and Choice Between Speaker A, B, or A+B

You can connect two separate speaker systems in different rooms and switch between them or operate both simultaneously. Four connections are available, allowing you to select the right speaker pair for the respective source with the push of a button.

Subwoofer Connection

The subwoofer connection can enhance the system’s bass reproduction for a more powerful sound with better quality.

Phono-MM Connection

A turntable with an MM phono module can also be connected. Enjoy vinyl recordings alongside CDs and experience the interplay of the latest digital and analog technology.

Minimalist Elegant Design

With its minimalist elegant design, this integrated amplifier stands firmly in the tradition of legendary Yamaha HiFi components. The aluminum front panel features a refined hairline finish and an intuitive arrangement of controls. The rotary knobs also share the same luxurious construction as our high-end models.

Remote Control with Clear Intuitive Design

The clear and simple design of the remote control allows intuitive one-handed operation. For example, volume or playback order can be easily and comfortably adjusted. The clear design with hairline finish perfectly complements the amplifier itself. The remote can also control a Yamaha CD player.

Rotary Knob with LEDs for Source Selection

A rotary knob makes selecting the input source easy and fast. The high-quality material with hairline finish offers a pleasant tactile feel. The selected source is indicated by LEDs, so switching between players is effortless even in dark rooms.

Auto-Standby Function

The amplifier’s power-saving function detects if it has not been used for a long time (about 8 hours) even though it is switched on. In this case, the device automatically switches to standby mode – minimizing power consumption if the amplifier was accidentally left on.
