The Yamaha A-S501SL is a 2-channel integrated amplifier delivering up to 100 W per channel at 6 Ohms with low distortion. It features multiple analog and digital inputs, tone controls, and high-quality binding post speaker outputs.
The Yamaha A-S501SL integrated amplifier combines a preamplifier and power amplifier in a single unit designed for high-fidelity audio reproduction. It provides 100 watts per channel into 6 Ohms with minimal total harmonic distortion, ensuring clear and powerful sound. The amplifier supports a wide frequency response from 20 Hz to 20 kHz with ±0.5 dB accuracy in Pure Direct mode and extends up to 100 kHz ±1 dB. Connectivity includes five stereo RCA inputs, a phono input with ground screw for turntables, optical and coaxial digital inputs, and a subwoofer output. Speaker connections are facilitated through four pairs of gold-plated binding posts. Additional features include bass and treble tone controls with ±10 dB adjustment, a headphone output, and a 192 kHz/24-bit DAC for high-resolution audio playback. The unit operates on 120 VAC power and measures 17.1 x 5.9 x 15.2 inches, weighing 22.7 pounds.
