Yamaha AS501 Integrated 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) Overview : ToP-ART (Total Purity Audio Reproduction Technology) and high quality parts - I/O (input to output) Direct Symmetrical Design - ART (Anti-Resolution and Tough) Base - Custom-made power transformer / 12,000uF block capacitors / Aluminum-extruded heat sinks 120W x 2 (max), 85W x 2 (RMS) high power output Pure Direct Mode for Greater Sound Purity Continuous Variable Loudness Control Gold-plated speaker terminals and RCA (CD, Phono) and coaxial terminals Digital audio inputs for TV or Blu-ray Player Connection for YBA-11 Bluetooth Wireless Adapter Simple yet sophisticated design (aluminium front panel and knobs) Auto Power Standby Receiver / Integrated Amplifier Minimum RMS Output Power (8 ohms, 20 Hz-20 kHz) 85 W + 85 W (0.019% THD) Maximum Power (4 ohms, 1kHz, 0.7% THD, for Europe) 120 W + 120 W High Dynamic Power/Channel (8/6/4/2 ohms) 130/150/185/220 W Damping Factor 240 Frequency Response 10 Hz-100 kHz +/-1.0 dB Total Harmonic Distortion (CD to Sp Out, 20 Hz-20 kHz) 0.019% (50 W/8 ohms) Signal-to-Noise Ratio (CD) 99dB (input shorted, 200 mV) Audio In / Out 8 / 2 Digital Input Yes (optical / coaxial) Subwoofer Out Yes DC out Yes Pure Direct Yes ToP-ART Yes Standby Power Consumption 0.5W Power Management (Auto Power Standby) Yes Dimensions (W x H x D) 435 x 151 x 387 mm Weight 10.3 kg; 22.7 lbs.
