Two channels driven continuously into 8-ohm loads:
0.1% distortion at 44.6 watts
1% distortion at 57.6 watts

Analog frequency response in Stereo mode:
–0.93 dB at 10 Hz; –0.26 dB at 20 Hz
–0.38 dB at 20 kHz; –1.99 dB at 50 kHz

Analog frequency response with signal processing:
–3.03 dB at 10 Hz; –0.89 dB at 20 Hz
–0.70 dB at 20 kHz; –39.27 dB at 50 kHz

This graph shows that the Classik Movie's left channel, from Aux1 input to speaker output with two channels driving 8-ohm loads, reaches 0.1 percent distortion at 44.6 watts and 1 percent distortion at 57.6 watts. Into 4 ohms, the amplifier reaches 0.1 percent distortion at 77.7 watts and 1 percent distortion at 95.4 watts. Please note that the lack of a multichannel input precludes testing five channels driven simultaneously.

THD+N from the amplifier was less than 0.025 percent at 1 kilohertz when driving 2.83 volts into an 8-ohm load. Crosstalk at 1 kHz driving 2.83 volts into an 8-ohm load was –91.48 decibels left to right and –87.65 dB right to left. The signal-to-noise ratio with 2.83 volts driving an 8-ohm load from 10 hertz to 24 kHz with "A" weighting was –92.01 dBrA.

From the Dolby Digital input to the loudspeaker output, the left channel measures –0.63 dB at 20 Hz and –0.39 dB at 20 kHz. The center channel measures –0.66 dB at 20 Hz and –0.30 dB at 20 kHz, and the left surround channel measures –0.67 dB at 20 Hz and –0.23 dB at 20 kHz. From the Dolby Digital input to the line-level output, the LFE channel is –0.12 dB at 20 Hz when referenced to the level at 40 Hz and reaches the upper 3-dB down point at 78 Hz and the upper 6-dB down point at 103 Hz.—MJP
