A-S801 Integrated Amplifier (Silver)

Product Description

Expand your listening horizons with the silver A-S801 Integrated Amplifier from Yamaha. Featuring up to 120W per channel of RMS power at 6 ohms, this amp is equipped with digital inputs for connecting devices like televisions and Blu-ray/DVD players. The A-S801 sports a USB input and a 32-bit ESS Sabre Premier Audio digital-to-analog converter for playing DSD and PCM files stored on your PC. This amplifier offers dual stereo outputs, giving you the ability to power two sets of speakers in different rooms and switch between them, or have them both playing at the same time. To increase the bass output of your sound system, there's also a terminal for connecting a subwoofer.

To reduce distortion and degradation and produce the cleanest possible sound, the A-S801 employs Pure Direct mode and CD Direct mode. Activated via buttons on the front of the unit, these modes cause input signals to bypass unused circuits and cuts off those circuits' power supply. To further ensure quality sound, the amplifier's continuously variable loudness control allows you to balance low and high frequency sounds so you can hear a full tonal range at any volume.

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.
