Built to be energy efficient, the amp uses a power management system to switch itself to idle mode when not in use. The A-S801's internal circuitry mirrors itself symmetrically to produce higher signal purity and lower degradation. The chassis is reinforced with a solid center bar to reduce vibration and features a brushed aluminum front panel and knobs. The system comes with a remote control for easy operation.
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 DVD/Blu-ray player. These inputs eliminate the need for conversion from digital audio to analog out, thus maintaining signal quality.

Engaged by a front panel switch, it matches CD signal levels so each stage produces less noise, resulting in improved signal-to-noise ratio and maintenance of the amp's total gain balance.
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.

The A-S801 features an analog loudness control on the front panel which lets you adjust the loudness effect as desired. Separate from the overall volume, this controls the balance of the low- and high-frequency 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.
This amplifier's left and right channels are organized in a straight, symmetrical layout for limiting distortion and increasing signal purity.

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.
