<b>A-S500</b>
The A-S500 is designed for superb musical expression with high performance, outstanding power and sound quality combining ToP-ART technology and ART Base chassis construction with gold–plated speaker terminals and dual aluminum heat sinks and a Center Bar for crisp, clean sound. Advanced features include continuously variable loudness control, Pure Direct, along with Yamaha iPod dock connection, for endless music enjoyment options.
<b>Features:</b>
- Dual aluminum-extruded heat sinks ensure effective heat dissipation and help achieve crisp, clean sound.
- Gold-plated speaker terminals and RCA in/out jacks are durable and provide highest quality connections.
- Center bar reinforces the internal structure to further prevent vibration from affecting the sound quality.
- Pure Direct uses the shortest signal route for higher sound purity with low noise and transmission losses.
- Yamaha's exclusive Continuously Variable Loudness Control for listening at low volumes.
- The built-in iPod Dock has an independent power supply for extremely high S/N ratio.
<b>12V Trigger Out (Control Out)</b>
The 12V trigger output can be used to automatically power on the components in Zone 2 when the main power is turned on. Output is a high 100mA, so relay operation is possible.
<b>Remote (IR) 2 In/Out and Remote 2 In</b>
These terminals let you connect an IR signal receiver for wireless remote control between the Main Zone and Zone 2.
<b>Speaker A/B and A+B Selection</b>
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.
<b>The Look and Texture of Quality</b>
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.
<b>ToP-ART Sound Quality Design</b>
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.
<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>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>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>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 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.
<b>New Remote Control</b>
The A-S500 has a slim remote capable of controlling the optional T-S500 tuner.
