Yamaha P2201 Professional Natural Sound Power Amplifier 230 watts 8ohm Stereo

Description

Yamaha P2201 Professional Natural Sound Power Amplifier 230 watts 8ohm Stereo.
I have had this amp for a couple years and can say the p2200 2201 amplifiers are some of my favorite amps I’ve owned. This amp is convection cooled ie. No noisy fans!! Plenty of output to drive most any pro audio or Hifi audiophile speakers. I have had no issues with this amp.
All sales final. Absolutely no returns.
Power Output Per Channel: (Refer to Figure 3. Ambient room temperature for tests: 25-degrees Centigrade.)
200 Watts continuous average sine wave power into 8 ohms with less than 0.05% THD, (Total Harmonic Distortion), over a bandwidth of 20Hz to 20kHz, both channels driven.
230 Watts continuous average sine wave power into 8 ohms with less than 0.05% THD, at 1 kHz, both channels driven.
Frequency Response: (Refer to Figure 5.) +0dB, -0.5dB, 20Hz to 50kHz.
Total Harmonic Distortion: (Refer to Figure 6.)
Less than 0.005% @ 50 Watts, 8 ohms, 1kHz.
Less than 0.01% @ 150 Watts, 8 ohms, 20Hz to 20kHz.
Intermodulation Distortion: (Refer to Figure 7.)

Input Sensitivity:
An input of +4dB* (1.23V), ±0.5dB, produces an output of 230 Watts into 8 ohms (maximum output power), INPUT attenuator set for maximum level.
Input Impedance:
25k-ohms, minimum (unbalanced).
Damping Factor: (@ 8 ohms / (Refer to Figure 8.) Greater than 300 at any frequency from 20Hz to 1kHz; greater than 70 at any frequency from 20Hz to 20kHz.

Rise Time:
3.8 microseconds, or better (10%-90% of 1 volt @ 1kHz square wave output).
Slew Rate:
45 volts per microsecond, or better (at 175 Watts into 8 ohms, 200kHz square-wave input).
Channel Separation: (Refer to Figure 10.)
At least 82dB at 1kHz, at least 75dB at 20kHz.
