Yamaha 2-Channel Integrated Amplifier in Black - AS-701BL

Yamaha AS-701BL 2-Channel Integrated Amplifier in Black

The Yamaha AS-701BL integrated amplifier delivers 100 W per channel into 8 ohms from 20 Hz-20 kHz at 0.019% THD, combining analog flexibility with optical and coaxial digital inputs for TVs and Blu-ray Disc players. Its ToP-ART architecture, CD Direct Amplification and Pure Direct mode prioritize short, symmetrical signal paths, while the moving-magnet phono input, subwoofer output and Speaker A, B or A+B selection support a versatile two-channel Hi-Fi system. Continuously variable loudness helps maintain tonal balance at softer listening levels, and the black finish with aluminum front panel provides direct, familiar control.

Key Features

100 W x 2 Stereo Drive

The Yamaha AS-701BL is rated for 100 W + 100 W minimum RMS output at 8 ohms across 20 Hz-20 kHz, with high dynamic power ratings of 140/170/220/290 W per channel into 8/6/4/2 ohms. This output foundation is built to handle demanding audio conditions while driving a home loudspeaker pair.

ToP-ART Symmetrical Circuit Design

Yamaha ToP-ART organizes the left and right channels in straight, symmetrical paths, helping make the audio signal less susceptible to noise and distortion. The ART Base bottom chassis and solid center bar add rigid support and help damp vibration for rich, musical stereo reproduction.

Premium Power and Audio Components

A custom-made power transformer, 12,000 uF block capacitors, direct signal-path speaker relays, one-point grounding and extruded aluminum heat sinks work together to support amplifier stability. Each component is selected and tested for its contribution to sound quality under demanding playback conditions.

CD Direct Amplification and Pure Direct

CD Direct Amplification creates a straight connection to the CD input to maximize that source's signal-to-noise ratio. Pure Direct sends music through the shortest available circuit route, bypassing the buffer amp and the tone, loudness and balance controls when you want a purer path from source to speakers.

Analog and Digital Source Connections

The optical input can accept TV audio, while the coaxial input connects a compatible Blu-ray Disc player and keeps source audio digital until conversion inside the amplifier. An MM phono input welcomes a turntable, and the subwoofer output adds powered low-frequency support, making this integrated amplifier a practical center for classic and current sources.

Two-Speaker-System Flexibility

Four speaker terminals let you connect two separate systems, then choose Speaker A, Speaker B or A+B from the selector dial. This makes it easy to use either pair independently or send the selected source to both systems at the same time.

Continuously Variable Loudness Control

The front-panel loudness control works separately from overall volume, adjusting the balance of low and high frequencies to compensate for the ear's natural losses at quiet levels. You can preserve a fuller tonal range without turning the system up.

Direct Controls and Automatic Standby

A rotary input selector with LED indicators makes the active source easy to identify, even in a dark room, while the remote provides one-hand access to input and volume functions and can operate a Yamaha CD player. When Auto Power Standby is engaged, the amplifier enters standby after eight hours without a user function.
