<b>The Look and Texture of Quality</b>
Offers the look and feel of the top-class A-S2000, with elegant aluminium front panel and silky touch volume/selector knobs. You can feel Yamaha’s commitment to quality when you touch the knobs.
<b>Pure Direct</b>
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.
<b>Highest Quality Parts</b>
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.
<b>New Speaker Terminals</b>
These high grade speaker terminals have gold plating for best connection and outstanding durability. The pitch between jacks is wider for easier insertion.
<b>Centre bar to reinforce the internal structure</b>
Centre bar reinforces the internal structure to further prevent vibration from affecting the sound quality.
<b>Dual aluminium-extruded heat sinks</b>
Dual aluminium-extruded heat sinks ensure effective heat dissipation and help achieve crisp, clean sound.
<b>Continuously Variable Loudness Control</b>
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.
<b>Special Power Supply for Clear iPod Sound</b>
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.
<b>Balanced System for Minimal Noise</b>
An unbalanced interface is subject to commonmode voltage noise, so Yamaha uses a balanced system to receive the iPod signal. This makes a significant contribution to reducing noise in the system for higher sound quality.
<b>Subwoofer Out</b>
Subwoofer Out lets you connect a subwoofer for stronger bass and better overall sound quality.
<b>Power management (Auto power off)</b>
Auto Power Off automatically turns off the power after a certain amount of time to save energy.
<b>New Remote Controls</b>
The A-S500 come supplied with a slim remote unit whose button layout is both easy to understand and use.
