Yamaha A-S501 Integrated Amplifier (Silver)

Expand your listening horizons with the silver 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
