200W MOSFET Audio Amplifier
Électronique /
Electronic
It has a rated power output of 140W into 8W and 200W into 4 Ohm.
Frequency response is within 1dB from 20Hz to 80kHz.
Total harmonic distortion is rated at less than 0.1% up to full power and signal-to-noise ratio with respect to 200W is better than 100dB unweighted.
