xpand your listening horizons with the silver A-S701 Integrated Amplifier from Yamaha. Featuring up to 120W per channel of RMS power at 6 ohms, this amp is equipped with digital inputs for connecting devices like televisions and Blu-ray/DVD players.

It offers dual stereo outputs, giving you the ability to power two sets of speakers in different rooms and switch between them, or have them both playing at the same time. To increase the bass output of your sound system, there's also a terminal for connecting a subwoofer.

  • 120W x 2 (RMS) Power Output
  • Optical and Coaxial Inputs
  • Speaker A, B or A+B Selection
  • Subwoofer Out
  • Continuously Variable Loudness Control
  • CD Mode and Pure Direct Mode
  • Power Management (Auto Power Off)
  • Reinforced Chassis
  • Symmetrical Layout
  • Brushed Aluminum Front Panel

• CD Direct Mode

Engaged by a front panel switch, it matches CD signal levels so each stage produces less noise, resulting in improved signal-to-noise ratio and maintenance of the amp's total gain balance.

• Pure Direct Mode

The Pure Direct mode causes the music signals to travel the shortest possible circuit route, bypassing the buffer amp and the tone, loudness and balance controls to virtually eliminate any signal degradation for the purest sound quality.

• Continuously Variable Loudness Control

The A-S701 features an analog loudness control on the front panel which lets you adjust the loudness effect as desired. Separate from the overall volume, this controls the balance of the low- and high-frequency sounds, providing full tonal range at any volume level, compensating for the natural loss in the human ear of high and low frequencies at soft levels.

• Direct Symmetrical Design

This amplifier's left and right channels are organized in a straight, symmetrical layout for limiting distortion and increasing signal purity.

• Anti-Resonance Chassis

The base of the A-S701's chassis is reinforced with a solid center bar to increase rigidity support and vibration damping, which limits resonance.

• Dual System Capable

You can connect two separate speaker systems in different rooms and switch between them or have them both play at the same time by switching the dial on the front of the unit.

• Phono MM Terminal

You can connect a turntable with an MM phono cartridge to play vinyl records, allowing you to enjoy records in addition to modern media sources.

Auto Power Standby Function

This amplifier puts itself into standby mode when it detects that it hasn't been used in approximately 8 hours, minimizing power consumption.

• Remote Control

Control your music from afar with the included remote, finished to match the design of the amplifier. The remote comes with batteries and can also be used to control a Yamaha CD player.

• Connection for Bluetooth Wireless Adapter

With the optional YBA-11 Bluetooth Wireless Adapter, you'll be able to stream music wirelessly from a Bluetooth capable mobile phone or a PC to the network receiver. This amplifier features a DC-out connection on the rear panel to power the adapter.

• Rotary Encoder Input Selector

The rotary encoder makes it quick and easy to select input sources, and the LEDs clearly show which source is selected so you can easily switch between them, even in a dark room.
