Speaker A/B and A+B Selection
Enjoy music in a second room! Just connect a second pair of speakers to the Speaker B terminals and you can listen to either pair or both of them at the same time.
The Look and Texture of Quality
Offers the look and feel of the top-class A-S2000, with elegant aluminum front panel and silky touch volume/selector knobs. You can feel Yamaha's commitment to quality when you touch the knobs.
ToP-ART Sound Quality Design
ToP-ART (Total Performance Anti-Resonance Technology) design uses a symmetrical layout for accurate sound field reproduction and the ART Base to eliminate effects from external vibration.
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.
New Speaker Terminals
These high grade speaker terminals have gold plating for best connection and outstanding durability. The pitch between jacks is wider for easier insertion.
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.
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 makes a significant contribution to reducing noise in the system for higher sound quality.
New Remote Control
The A-S500 has a slim remote capable of controlling the optional T-S500 tuner
