Yamaha HIFI package A-S801+NS-B330

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

In order to effectively dampen the vibrations that have adverse effects on sound quality, the A-S801 chassis has a double bottom with a 1mm iron plate. In addition, the power transformer and heat sinks in the power amp section are supported by an extremely strong and stable ART (Anti-Resonance and Tough) base. A solid centre bar further enhances high rigidity support and vibration damping. These Yamaha design innovations contribute to superior S/N ratio and natural, rich sound reproduction.

High sound quality circuit design based on the ToP-ART (Total Purity Audio Reproduction Technology) concept

ToP-ART Design and ART Base Ensure Optimum Sound When processing and transmission of the audio signal is simple and direct there is less chance of it being affected by noise and distortion. Yamaha’s amplifier design technology called ToP-ART features an I/O (input to output) Direct Symmetrical Design, with left and right channels organised in a straight, symmetrical layout for highest signal purity.

High Quality Parts for Outstanding Audio Performance

Custom-made power transformer, custom-made block capacitors, two direct signal path speaker relays, onepoint grounding system, aluminium-extruded heat sinks and other top-quality parts effortlessly handle demanding audio signal conditions. The quality of each individual part, as well as how they work together, basically determines the sound quality of any component. Yamaha uses only very high quality parts, carefully selected and tested.

CD Direct Amplification and Pure Direct Mode for Greater Sound Purity

With a straight connection to the CD input, CD Direct Amplification maximises CD source S/N ratio. Additionally, engaging 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-S801 also feature a new analogue 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 highfrequency 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.

Gold-plated Terminals

Gold-plated terminals ensure a high quality connection that prevents signal loss. the A-S801 have gold-plated speaker terminals and input terminals.

USB DAC Function Supports 2.8MHz/5.6MHz DSD Native Resolution and PCM384kHz/32*bit Reproduction

USB DAC function supports 2.8MHz/5.6MHz DSD native resolution and PCM 384kHz/32-bit* reproduction

A built-in USB DAC function allows direct connection to a PC and reproduction of today's popular high resolution sound sources. The Yamaha-developed USB device controller IC has its own master clock that eliminates PC jitter for high resolution signal transmission. The ASIO2.3 Yamaha Steinberg USB driver achieves lower delay and higher throughput. Offering compatibility with 5.6MHz DSD native reproduction and PCM 384kHz/32-bit PCM reproduction, you can enjoy a wide range of high resolution sound sources for high quality sound. In addition, an indicator on the front panel displays easily understandable DSD and PCM playback formats and sampling frequencies.

* Windows support. Mac support is 24-bit.

Exceptionally High Performance 32-bit D/A Converter

The D/A converter for the A-S801 is the ES9010K2M from ESS Technology, Inc. We selected this after careful examination of all points—not only its high precision processing of 32-bit audio, but also the ability to handle large amounts of audio data with full PCM 384kHz,DSD 5.6MHz native reproduction, strength in the low register, and high quality definition in the high register. Since the built-in D/A converter generates its own master clock, an original Jitter Elimination function is also included, permitting D/A conversion with extremely low impact of clock jitter. Moreover, a 2-channel D/A converter is housed inside the chip, and applies double differential operation. The result is exceptionally high performance and high quality signal output with superior signal-to-noise ratio.

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

The A-S801 equipped for digital audio input with both optical and coaxial terminals. The optical is for receiving audio from a TV, and the coaxial for receiving audio from a Blu-ray player. The audio stays in the digital domain, giving you pure, pristine dynamic sound for all your entertainment sources, from sports and other programs to movies and concerts.

Connection for YBA-11 Bluetooth Wireless Adapter

With the YBA-11, you’ll be able to stream music wirelessly from a Bluetooth capable mobile phone or a PC to the Network receiver. Thanks to the digital connection and aptX® audio coding algorithm, you’ll 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 the amplifier.

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

You can connect two separate speaker systems in different rooms and switch between them, or have them both playing at the same time. There are four terminals, so by just pushing a button, you can switch speakers to match the sound 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 an MM phono cartridge to play vinyl records. This lets you enjoy not only CDs, but also analogue record sound from an amp with the latest digital/analogue technology.

Simple yet Sophisticated Design

With a beautifully simple and unique design inherited directly from Yamaha’s HiFi audio components, these amplifiers also boast an easyto- operate button layout. The aluminium 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 easyto- understand one-hand operation. The easy-to-use design makes it simple to adjust song volume and order. 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 luxury hairline finish material 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

The amplifier has a power management function that detects when it hasn't been used for a long time (about 8 hours) even though the power is on, and automatically shifts it into standby mode. So even if you forget to turn it off, power consumption will be minimised.













Full Spec Entry Class Model. A Small HiFi Bookshelf Unit that Makes Listening to Music a Pleasure

In this era of high spec sources, we are looking toward the future of small bookshelf speakers, not only providing good value for price. It utilises an all-new high resolution compatible dome tweeter that makes it completely different from ordinary speakers that claim high resolution compatibility: 40kHz. The focus is on tuning that brings out the reality of vocals, where listeners notice differences in quality the most, and on delivering expansive high and low tones without colouration.

Expansive, Glistening Sound. A New 3 cm (1”) Aluminium Dome Tweeter that Reproduces 45 kHz (–10 dB) High Frequencies

With the characteristics and sound quality you would expect from a next generation unit, it features a new structure that places a newly revised aluminium dome inside the voice coil for both weight and strength. The aluminium’s Black Anodised processing suppresses the aluminium-specific metallic character of its sound, producing a natural, glistening sound quality without colouration. The diffuser features a new shape, and the voice coil is comprised of CCAW (copper-coated aluminium wire) reengineered in material and linearity. While maintaining the amount of information and energy in the audible band it achieves 45 kHz (–10 dB) reproduction with extended high frequencies. This is truly a breakthrough in high frequency reproduction.

Tweeter Features a Unique Waveguide Horn for Directivity Control

The unique waveguide horn and tweeter utilise the same waveguide technology used for directivity control in studio monitor speakers to control the incidence of indirect sound. The Vertical and horizontal directivity control increases the sense of sound field, providing vivid stereo reproduction.

Supple and strong. 13 cm (5”) Woofer Utilises a PMD cone with a Proven Track Record in Europe and Japan

Incorporating 30% high quality white mica, the 13 cm (5”) woofer utilises a lightweight, high rigidity PMD (Polymer-injected Mica Diaphragm) cone that achieves ideal internal loss and high elasticity characteristics. The new design put both the voice coil and spider under the knife, achieving massive, expansive low tones. As the future of HiFi small bookshelf speakers, its supple and strong bass redefines musical expressiveness.

Rounded Front Baffle with Double Structure

The cabinet features a rounded shape that curves smoothly to both sides. By reducing the number of parallel surfaces it minimises standing waves and unwanted resonance. The front baffle has a double structure with a mirror-like piano finish. With reinforced strength, it produces more natural, extremely transparent high tones.
