Yamaha A-S501-BLACK Integrated Hi-Fi

The Yamaha A-S501 is an integrated Hi-Fi amplifier. The amplifier design technology from Yamaha is called ToP-ART which features an input to output with a direct symmetrical design. ToP-ART design and ART Base ensure optimum sound when processing and transmitting the audio signal. The signal is simple and direct, therefore it is less likely to be affected by noise and distortion. The left and right channels are organized in a straight, symmetrical layout for the highest signal purity. In addition, the ART (Anti-Resonance and Tough) Base bottom chassis and a solid center bar provide high rigidity support and dampers vibration. These design innovations contribute to this amplifier's rich audio reproduction with abundant musicality.Yamaha A-S501 Features:85 W x 2-ch (20 Hz - 20 kHz)Digital audio inputs for TV and Blu-ray Disc™ playerPure Direct mode for greater sound purityToP-ART (Total Purity Audio Reproduction Technology) and high quality partsI/O (input to output) direct symmetrical designART (Anti-Resonance and Tough) BaseCustom-made power transformer / 12,000 µF block capacitors / extruded aluminum heat sinksGold-plated speaker terminals and RCA terminalsSimple yet sophisticated design (aluminum front panel and knobs)Continuously Variable Loudness ControlYamaha A-S501 Specifications:Minimum RMS Output Power (8 ohms, 20 Hz-20 kHz): 85 W+ 85 W (0.019% THD)High Dynamic Power/Channel (8/6/4/2 ohms): 130 / 150 /185 / 220 WFrequency Response: 10 Hz -100 kHz +/- 1.0 dBTotal Harmonic Distortion (CD to Sp Out, 20 Hz-20kHz): 0.019% (50 W / 8 ohms)Signal-to-Noise Ratio (CD): 99 dB (input shorted, 200mV)Damping Factor: 240Digital Input: Yes (optical / coaxial)Audio In / Out: 8 / 2Subwoofer Out: YesPure Direct: YesToP-ART: YesDC out: YesStandby Power Consumption: 0.5 WPower Management (Auto Power Standby): YesDimensions (W x H x D): 17-1/8" x 6" x 15-1/4"Weight: 22.7 lbs.
