High Quality Circuit Design Based on the ToP-ART (Total
Purity Audio Reproduction Technology) Concept
The amplifier design technology from Yamaha is called
ToP-ART which features an input to output with a direct symmetrical design.
ToP-ART design and ART Base ensure optimum sound when processing and
transmitting the audio signal. The signal is simple and direct, therefore it is
less likely to be affected by noise and distortion. The left and right channels
are organized in a straight, symmetrical layout for the highest signal purity.
In addition, the ART (Anti-Resonance and Tough) Base bottom chassis and a solid
center bar provide high rigidity support and dampers vibration. These design
innovations contribute to this amplifier’s rich audio reproduction with
abundant musicality.
High Quality Parts for Outstanding Audio Performance
Notice the custom made power transformer, custom made block
capacitors, two direct signal path speaker relays, one point grounding system,
extruded aluminum heat sinks and other top quality parts to effortlessly handle
demanding audio conditions. The quality of each individual part, as well as how
they work together, basically determines the sound quality of this component.
Yamaha uses only very high quality parts, carefully selected and tested for their
sound properties.
Created by Rich Experience, Tradition and High
Technological Expertise
Yamaha, with a long history of over 125 years as a musical
instrument maker, also has a high reputation for Hi-Fi components. The A-S701
is created by taking advantage of this rich experience and high technological
expertise. Based on the concept of “Natural Sound” for reproducing all music as
it really sounds, this amplifier is built with scrupulous care from its circuit
design to basic sound production.
CD Direct Amplification and Pure Direct Mode for Greater
Sound Purity
With a straight connection to the CD input, CD Direct
Amplification maximizes the CD source’s signal to noise ratio. Additionally,
engaging the Pure Direct mode causes the music signals to travel the shortest
possible circuit route, bypassing the buffer amp, the tone, loudness and
balance controls to virtually eliminate any signal degradation for the purest
sound quality.
Continuously Variable Loudness Control
The A-S701 also features a new analog loudness control on
the front panel that uses electronic volume for higher sound quality which lets
you adjust the loudness effect as desired. Separate from the overall volume, this
controls the balance of the low and high frequencies providing 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 equipped for digital audio inputs with an
optical and digital coaxial input terminal. The optical is for receiving audio
from a TV and the coaxial for receiving audio from a Blu-ray Disc player. The
audio stays in the digital domain giving you pure, pristine and dynamic sound
for all of your entertainment sources.
Connection for YBA-11 Bluetooth® Wireless
Adapter (Optional Accessory)
With the YBA-11, you’ll be able to stream music wirelessly
from a Bluetooth® compatible mobile phone or a PC. Thanks to the
digital coaxial connection and the aptX® audio coding algorithm, you will enjoy
wireless music streaming with optimum sound quality. You can also conveniently
power the YBA-11 via the DC out connection 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 Moving Magnet Input 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 control knobs are also of the same luxurious construction
as used on our top end models.
Remote Control with Clean, Simple Design
The clean, simple design of the remote control provides easy
to understand operation with a single hand. The design makes it simple to
adjust inputs, volume and more. The unit has a sophisticated looking hairline
finish that matches the design of the amplifiers. You can also use the remote
to control a Yamaha CD player.
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
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.
