The Look and Texture of Quality

The A-S300 offers the look and feel of the top-class A-S2000 with elegant aluminum front panel and silky touch volume/selector knobs. You can see Yamaha’s commitment to quality in every part of this component.
Pure Direct

Music signals travel the shortest possible route, bypassing the buffer amp and tone, loudness and balance controls to virtually eliminate any signal degradation for the purest sound quality.
Highest Quality Parts

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.
New Speaker Terminals

These high grade speaker terminals have silver plating for best connection and outstanding durability. The pitch between jacks is wider for easier insertion.
Dual Aluminium-extruded Heat Sinks

Dual aluminium-extruded heat sinks ensure effective heat dissipation and help achieve crisp, clean sound.
Continuously Variable Loudness Control

Our ears lose sensitivity to high and low frequencies at low volume levels. This control lets you turn down the volume while maintaining the optimum frequency response.
Special Power Supply for Clear iPod Sound

The iPod dock has an independent power supply to prevent operating or charging current from the iPod from flowing into the amp ground signal. This ensures optimum iPod sound quality.
Balanced System for Minimal Noise

An unbalanced interface is subject to common-mode voltage noise, so Yamaha uses a balanced system to receive the iPod signal. This provides a higher sound quality by making a significant contribution to noise reduction in the system.
Subwoofer Out

Subwoofer out lets you connect a subwoofer for stronger bass and better overall sound quality.
Power Management (Auto Power Off)

Auto Power Off automatically turns off the power after a certain amount of time to save energy.
New Remote Control

The A-S300 includes a slim remote control unit with a buttons that are both easy to use and understand.
Technology
ToP-ART

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 (Total Purity Audio Reproduction Technology) features I/O (input to output) Direct Symmetrical Design, with left and right channels organized in a straight, symmetrical layout for highest signal purity.
Auto Power Off

When the automatic power down function is enabled, this unit will automatically switch to standby mode.
