A-S501 Integrated Amplifier (Black)

Product Description

Expand your listening horizons with the black A-S501 Integrated Amplifier from Yamaha. Featuring up to 100W 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. It 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-S501 employs Pure Direct Mode. Activated via a button on the front of the unit, this mode causes 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.

This Yamaha amplifier was built with energy efficiency in mind, and uses a power management system to switch itself to idle mode when not in use. The A-S501'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.
