+1.02 dB at 20 kHz
–17.55 dB at 50 kHz

This graph shows that the ZP100's left amplifier channel, with two channels driving 8-ohm loads, reaches 0.1% distortion at 52.6 watts and 1% distortion at 66.3 watts. Into 4 ohms, the amplifier reaches 0.1% distortion at 82.4 watts and 1% distortion at 98.1 watts. An input level of 249 millivolts was required to produce an output of 2.83 volts into an 8-ohm load, indicating an overall gain of 21.17 decibels.

THD+N from the amplifier was less than 0.022% 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 –91.33 dB left to right and –94.05 dB right to left. The signal-to-noise ratio with 2.83 volts driving an 8-ohm load from 10 Hz to 24 kHz with "A" weighting was –94.91 dBrA.—MJP
