  • Yamaha A-S801 Integrated Amplifier

    With high sound quality ToP-ART circuitry and high stability construction, this integrated amplifier delivers superior musicality and powerful sound. And by incorporating advances like a USB DAC function, it fully supports the latest high resolution sound formats.

    • USB DAC function supports 2.8MHz/5.6MHz DSD native resolution and PCM384kHz/32*bit reproduction
    * Windows support. Mac support is 24-bit.
    • High efficiency ESS 32bit DAC (ES9010K2M)
    • Digital signal indicator shows DSD and PCM playback formats and sampling frequencies
    • High strength chassis contributes to high purity audio reproduction
    - Double-bottom chassis for excellent vibration damping
    • ToP-ART (Total Purity Audio Reproduction Technology) and high quality parts
    - I/O (input to output) Direct Symmetrical Design
    - ART (Anti-Resolution and Tough) Base
    - Custom-made power transformer / 12,000uF block capacitors / Aluminium-extruded heat sinks
    • 160W x 2 (max), 100W x 2 (RMS) high power output
    • CD Direct Amplification and Pure Direct
    • Continuous Variable Loudness Control
    • Gold-plated speaker terminals and RCA terminals
    • Digital audio inputs for TV or Blu-ray Player
    • Connection for YBA-11 Bluetooth Wireless Adapter

    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
    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.

    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.
