The Yamaha A-S701BL is a 2-channel integrated amplifier delivering up to 120W per channel at 6 Ohms with low distortion. It features multiple analog and digital inputs, including phono and optical, and offers precise tone control and high-fidelity audio performance.

The Yamaha A-S701BL integrated amplifier combines a preamplifier and power amplifier in a single unit designed for high-quality audio reproduction. It provides 120 watts per channel at 6 Ohms with minimal total harmonic distortion, ensuring clear and powerful sound output. The amplifier supports a wide frequency response range from 20 Hz to 20 kHz with tight tolerance in Pure Direct mode, and extends up to 100 kHz for enhanced audio detail.

Connectivity options include five stereo RCA inputs, a dedicated phono input with ground screw, optical TOSLINK, digital coaxial inputs, and a subwoofer output. Speaker connections utilize gold-plated binding posts for reliable signal transmission. Additional features include bass and treble tone controls with ±10 dB adjustment, a high damping factor for speaker control, and a 192 kHz/24-bit DAC supporting PCM audio. The unit also offers a front headphone output and a USB-A port for power.

With a robust build measuring 17.1 x 5.9 x 15.2 inches and weighing 24.7 pounds, the A-S701BL is suitable for professional audio setups requiring precise sound quality and versatile input options.
