Product Description: 

High Sound Quality Circuit Design Based on the ToP-ART (Total Purity Audio Reproduction Technology) Concept

The ToP-ART Design, along with the ART Base, guarantees optimal sound quality during the processing and transmission of the audio signal. By maintaining simplicity and directness, the signal is less susceptible to noise and distortion. The left and right channels are meticulously organized in a straight, symmetrical layout to uphold the highest level of signal purity.

High Strength Chassis Contributes to High Density Sound and Pure Audio Reproduction

The A-S701 chassis is engineered with a double bottom design featuring a 1 mm iron plate to effectively dampen vibrations that can degrade sound quality. Furthermore, the power transformer and heat sinks in the power amp section are bolstered by an exceptionally robust and stable ART (Anti-Resonance and Tough) base. Adding to this, a solid center bar enhances overall rigidity while further dampening vibrations. These innovative design elements from Yamaha culminate in superior signal-to-noise ratio and rich, natural sound reproduction.

High-Quality Parts for Outstanding Audio Performance

The A-S701 boasts custom-made power transformers, custom-made block capacitors, two direct signal path speaker relays, a one-point grounding system, extruded aluminum heat sinks, and other top-quality components engineered to effortlessly handle demanding audio conditions. Each individual part, as well as their collective synergy, plays a crucial role in determining the sound quality of this component. Yamaha meticulously selects and tests only the highest quality parts for their superior sound properties, ensuring unparalleled audio performance.

Created by Rich Experience, Tradition, and High Technological Expertise

With a musical instrument-making heritage spanning over 125 years, Yamaha has earned a stellar reputation for its Hi-Fi components. The A-S701 amplifier is a testament to the culmination of this rich experience and high technological expertise. Built upon the concept of "Natural Sound," which aims to faithfully reproduce music as it truly sounds, this amplifier is crafted with meticulous care, from its circuit design to its fundamental sound production.

CD Direct Amplification and Pure Direct Mode for Greater Sound Purity

With a direct connection to the CD input, CD Direct Amplification optimizes the signal-to-noise ratio of CD sources, ensuring maximum fidelity. Moreover, activating the Pure Direct mode enables music signals to traverse the shortest circuit route, bypassing the buffer amp, tone, loudness, and balance controls. This effectively eliminates any potential signal degradation, resulting in pristine sound quality for the ultimate listening experience.

Continuous Variable Loudness Control

The A-S701 introduces a new analog loudness control on the front panel, employing electronic volume for enhanced sound quality while allowing you to adjust the loudness effect to your preference. Distinct from the overall volume control, this feature adjusts the balance of low and high frequencies, ensuring a full tonal range at any volume level by compensating for the natural loss in the human ear at soft levels.

Gold Plated Terminals

Gold plated terminals ensure a high quality connection that prevents signal loss. The A-S701 has gold plated speaker and input terminals.

Digital Audio Input for TV and/or Blu-ray Disc™ Player

The A-S701 is outfitted with digital audio inputs, featuring both optical and digital coaxial input terminals. The optical input is designed to receive audio from a TV, while the coaxial input is intended for audio from a Blu-ray Disc player. By keeping the audio in the digital domain, this setup ensures pure, pristine, and dynamic sound reproduction for all your entertainment sources.

Connection for YBA-11 Bluetooth® Wireless Adapter (Optional Accessory)

By incorporating the YBA-11 Bluetooth® Wireless Adapter, you gain the ability to wirelessly stream music from a Bluetooth® compatible mobile phone or PC. Leveraging the digital coaxial connection and the aptX® audio coding algorithm, you'll experience wireless music streaming with optimal sound quality. Additionally, you can conveniently power the YBA-11 via the DC out connection located on the rear panel of this amplifier.

Speaker A, B or A+B Selection and Speaker Terminals for Two Systems

You can connect two separate speaker systems and hear them in different rooms at the same time. There are four terminals, so by just rotating a simple selector dial you can switch between the two pairs of speakers to play the selected source.

Subwoofer Terminal

A terminal for connecting a subwoofer is provided, allowing you to increase the bass output of your system for a more powerful sound with better overall sound quality.

Phono MM Terminal

You can connect a turntable with a MM phono cartridge to play vinyl records. Get the best of both worlds whether listening to analog vinyl or the latest digital technology.

Simple Yet Sophisticated Design

With a beautiful, simple and unique design inherited directly from Yamaha Hi-Fi audio components, this amplifier also boasts an easy to operate layout. The aluminum front panel has a richly textured silver hairline finish. The main control knobs are also of the same aluminum finish as used on our top end models.

Remote Control with Clean, Simple Design

The remote control's clean and straightforward design ensures easy one-handed operation, allowing for intuitive adjustment of inputs, volumes, and more. Its sophisticated hairline finish complements the design of the amplifiers, adding a touch of elegance to your setup. Additionally, you can conveniently use the remote to control a Yamaha CD player, enhancing your overall listening experience.

Rotary Encoder Input Selector with LEDs

The rotary encoder makes it quick and easy to select input sources. The luxurious hairline finish offers a nice tactile feeling. LEDs clearly show which source is selected so you can easily switch sources, even in a dark room.

Auto Power Standby Function

When Auto Power Standby is engaged the amplifier will automatically shift itself into standby mode when a user function has not been executed in eight hours. This a great function if you forget to turn the amplifier off and it will help minimize power consumption when the unit is not in use.
