About the A-S500
The Yamaha A-S500 is a stereo integrated amplifier built around Yamaha’s ToP-ART signal-path design and ART Base chassis construction. It provides 85 W per channel into 8 ohms, an MM phono input, multiple line-level inputs, speaker A/B selection, a subwoofer output, and a headphone output. Pure Direct bypasses tone and balance circuitry, while continuously variable loudness control allows adjustment for listening at different levels.
