Yamaha A-S301 | Integrated Amplifier

Natural Sound • Precision Design • Pure Musicality

The Yamaha A-S301 embodies the essence of Yamaha’s “Natural Sound” philosophy — reproducing every note exactly as intended. Built on the renowned ToP-ART (Total Purity Audio Reproduction Technology) platform, this amplifier delivers clean, balanced, and distortion-free performance with the warmth and authority Yamaha is celebrated for.

High Quality Circuit Design Based on the ToP-ART (Total Purity Audio Reproduction Technology) Concept

Yamaha’s advanced ToP-ART design features a direct, symmetrical circuit layout from input to output. By minimizing signal path complexity, it preserves absolute signal purity.
The ART (Anti-Resonance and Tough) Base and solid center bar provide exceptional rigidity and vibration damping — ensuring stable performance and rich, musical sound reproduction with abundant clarity and detail.

High Quality Parts for Outstanding Audio Performance

Every component of the A-S301 is built to deliver uncompromising fidelity.
Custom-made power transformers, block capacitors, signal path relays, extruded aluminum heat sinks, and a one-point grounding system work together to minimize distortion and ensure maximum transparency. Each part is rigorously tested for its sonic contribution, reflecting Yamaha’s meticulous engineering philosophy.

Created by Rich Experience, Tradition and High Technological Expertise

With over 125 years of musical excellence, Yamaha combines craftsmanship and advanced engineering to create the A-S301. Built on the brand’s Natural Sound legacy, this amplifier offers a genuine musical experience — carefully tuned from circuit layout to final assembly for true high-fidelity performance.

Pure Direct Mode for Greater Sound Purity

Activate Pure Direct mode to achieve the shortest signal path possible. This bypasses tone, loudness, and balance circuits, virtually eliminating signal degradation for the cleanest and most transparent sound reproduction.

Continuously Variable Loudness Control

Unlike traditional volume adjustments, this advanced analog loudness control fine-tunes tonal balance at any volume level. It compensates for natural human hearing loss at low volumes, maintaining full-range dynamics and rich tonal character whether you’re listening softly or loud.

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

Equipped with both optical and coaxial digital inputs, the A-S301 seamlessly connects to TVs, Blu-ray players, and other digital sources — ensuring pure, dynamic, and distortion-free playback without ever leaving the digital domain.

Connection for YBA-11 Bluetooth® Wireless Adapter (Optional Accessory)

Add wireless convenience with the optional Yamaha YBA-11 Bluetooth adapter. Enjoy high-quality streaming from mobile devices or PCs via aptX® technology. Powered directly from the A-S301’s rear DC out port, this simple addition expands your modern listening options.

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

Easily connect two pairs of speakers for flexible playback in different rooms. With four terminals and a simple selector dial, you can switch between systems or run both simultaneously — ideal for multi-room enjoyment.

Subwoofer Terminal

A dedicated subwoofer output allows you to enhance low-end performance, adding depth and authority for a more immersive and powerful listening experience.

Phono Moving Magnet Input Terminal

Connect your turntable (MM cartridge) directly and rediscover the warmth of analog vinyl alongside your modern digital sources — true versatility for every music lover.

Simple Yet Sophisticated Design

The A-S301 reflects Yamaha’s timeless design language: understated, elegant, and functional.
Its aluminum front panel features a refined silver hairline finish, offering both tactile pleasure and aesthetic harmony in any setup.

Remote Control with Clean, Simple Design

Designed for intuitive use, the remote control provides effortless access to input selection and volume control. Its elegant finish matches the amplifier’s design, and it can also control compatible Yamaha CD players for added convenience.

Rotary Encoder Input Selector with LEDs

The precision rotary encoder ensures smooth source selection. Bright, easy-to-read LED indicators confirm your chosen input — even in low-light environments — while the luxurious finish enhances the overall tactile experience.

Auto Power Standby

For convenience and energy efficiency, the Auto Power Standby function automatically powers down the amplifier after eight hours of inactivity — helping conserve power without compromising readiness.
