CD Direct Amplification and Pure Direct Mode for Greater Sound PurityWith 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
Gold Plated TerminalsGold 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 SystemsYou can connect two separate speaker systems and hear them in different rooms at the same time.

Subwoofer TerminalA 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 TerminalYou 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 DesignWith 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 DesignThe 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 LEDsThe 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 AdapterWith 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.
