The above measurement shows that the AVR 7000's left amplifier channel, with two channels driving 8-ohm loads, began clipping at 0.008% distortion and 131.4 watts. The amp reaches 0.1% distortion at 151.5 watts and 1% distortion at 169.3 watts, as shown above. Into

4 ohms, the amplifier begins clipping at 161.3 watts and reaches 0.1% distortion at 236.0 watts and 1% distortion at 283.3 watts. The analog frequency response was +/-0.34 decibels from 20 hertz to 20 kilohertz. The response dropped to -0.23 dB at 10 Hz and to -1.48 dB at 50 kHz. THD+N from the amplifier was less than 0.028% at 1 kHz driving 2.83 volts into an 8-ohm load.

From the Dolby Digital input to the loudspeaker outputs, the left, center, and surround channels are all flat, +/-0.58 dB from 20 Hz to 20 kHz. From the Dolby Digital input to the line-level output, the LFE channel is +0.6 dB at 20 Hz, reaches the upper 3-dB down point at 89 Hz, and reaches the 6-dB down point at 137 Hz when normalized to the level at 40 Hz.—AJ
