This graph shows that the D 3020’s left amplifier channel, with two channels driving 8-ohm loads, reaches 0.1% distortion at 42.6 watts and 1% distortion at 52.6 watts. Into 4 ohms, the amplifier reaches 0.1% distortion at 58.8 watts and 1% distortion at 63.5 watts.

THD+N from the amplifier was less than 0.007% at 1 kHz when driving 2.83 volts into an 8-ohm load. Crosstalk at 1 kHz driving 2.83 volts into an 8-ohm load was –81.39 dB left to right and –76.92 dB right to left. The signal-to-noise ratio with an 8-ohm load from 10 Hz to 24 kHz with “A” weighting was –109.14 dBrA.—MJP
