Description 
 
2-channel class A amplifier with idle current 1.5A per channel. Class A operation is fulfilled up to 3A output current. Strong local feedback in the output stage (Q1 and Q2) minimizes output stage nonlinear distortion to less than 0.001% THD. 
 
Specifications 
 
Output power 2 x 20W/4 ohm, 2 x 12W/8 ohm (2016 version) 
Output power 2 x 35W/4 ohm, 2 x 20W/8 ohm (2022 version) 
Input impedance 47kohm 
Frequency range 2Hz - 270kHz (-3dB) 
Amplitude response drop at 20Hz: -0.02dB/4ohm 
Amplitude response drop at 20kHz: -0.01dB/4ohm 
Output noise voltage for bandwidth 22kHz: 32uV (2022 version) 
S/N ratio for bandwidth 22kHz: 99dB/2.83Vef, 112dB full output voltage (2022 version) 
THD+N at 1kHz for output power10W/8ohm, bandwidth 22kHz: 0.00036% (2022 version) 
Square wave response 10kHz 
Gain 27.01dB (22.41 x) |
