USB DAC Function Supports Native DSD (2.8 MHz / 5.6 MHz) and PCM (384 kHz / 32-bit) Resolutions
The USB DAC function supports native DSD (2.8 MHz and 5.6 MHz) and PCM (384 kHz / 32-bit*) resolutions. This function allows for a direct connection to PCs which opens the door to play back of the highest resolution audio content offered today. The Yamaha-developed USB device controller has its own master clock that eliminates PC jitter. The driver is a low loss, high throughput ASIO 2.3 Yamaha Steinberg USB driver. During playback, indicators on the front panel clearly show which sampling frequencies are currently being used.
*Windows supported. Mac® support is 24-bit.
Exceptionally High Performance 32-bit D/A Converter
After careful listening evaluations, Yamaha selected the 32-bit, 2-channel SABRE™ Premier Audio DAC from ESS Technology, Inc. Most notable is its high precision processing power of 32-bit audio along with the ability to handle large amounts of audio data with full PCM 384 kHz and native DSD 5.6 MHz. 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 an extremely low impact of clock jitter. Moreover, a 2-channel D/A converter is housed inside the chip which applies a double differential operation. The result is exceptional high performance and high quality signal output with a superior signal to noise ratio.
Digital Audio Input for TV and/or Blu-ray Disc™ Player
The A-S801 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 your entertainment sources.
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 sources 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.
Continuous Variable Loudness Control
The A-S801 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-S801 has gold plated speaker and input terminals.
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.
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 clean, simple design of the remote control provides easy to understand “one handed” operation. The design makes it simple to adjust inputs, volumes 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.
Connection for YBA-11 Bluetooth® Wireless Adapter
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’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 this amplifier.
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.
Why choose between analog and digital? Hear the best of both!
There are lots of ways to use your computer as a music source. But few of them are as simple and rewarding as connecting it to the Yamaha A-S801. This integrated amplifier has a USB input, so you can play digital tunes from your computer, including high-resolution files. Of course, this amp also offers lots of power to drive your stereo speakers. There are plenty of other inputs for disc players, a turntable, and even a TV or Blu-ray player. This versatility makes the A-S801 an excellent choice for anyone looking to design a fantastic two-channel rig with digital and analog capabilities.
Digital connections with high-resolution playback
When you connect your computer to the A-S801's USB input, your digital tunes will benefit greatly from this amp's high-quality ESS SABRE digital-to-analog converter (DAC). It converts your digital files into analog signals, preserving all of their detail, for accurate sound. This DAC can also handle high-resolution music, including DSD files and 24-bit/192kHz PCM files. There are also optical and coaxial digital inputs — connect a TV or Blu-ray player to these inputs, and enjoy movie sound through your stereo speakers.
Great sound from any source
With digital or analog signals, this amp delivers sound that's dynamic and clear. Thanks to anti-resonance construction, a symmetrical circuit layout, and high-quality components, the A-S801 keeps distortion levels incredibly low for superb sound quality. If you need to make some adjustments as you listen, there are front-panel tone controls for bass and treble. There's also a loudness control, for bringing out more detail and depth while listening at low volume. Or, bypass these controls with Pure Direct mode, which eliminates signal degradation as your music travels a more direct circuit path. For listening to CDs, engage CD Direct Amplification — it matches the input levels of the source with the amp to further minimize noise introduced at the amplification stage.

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 transmitting the audio signal. The signal is simple and direct, therefor 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.
High Strength Chassis Contributes to High Density Sound and Pure Audio Reproduction
In order to effectively dampen the vibrations that have adverse effects on sound quality, the A-S801 chassis has a double bottom design with a 1 mm 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 center bar further enhances high rigidity and dampens vibrations. These Yamaha design innovations contribute to superior signal to noise ratio with rich, natural sound reproduction.
High Quality Parts for Outstanding Audio Performance
Notice a 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.
