AV Receivers

This graph shows that the AVR-4308CI's left channel, from Multi input to speaker output with two channels driving 8-ohm loads, reached 0.1% distortion at 198.6 watts and 1% distortion at 218.9 watts. The distortion level remained at or below 0.002% across all power levels until it reached about 165 watts. Into 4 ohms, the amplifier reached 0.1% distortion at 298.0 watts and 1% distortion at 343.4 watts.

With five channels driven continuously into 8-ohm loads, the receiver reached 0.1% distortion at 144.8 watts and 1% distortion at 173.6 watts. With seven channels driven continuously into 8-ohm loads, it reached 0.1% distortion at 124.5 watts and 1% distortion at 150.3 watts.

The manufacturer's specs indicate a power output of 140 watts into 8 ohms with a distortion of 0.05% (number of channels not specified). With seven channels driven into 8 ohms, the receiver reached distortion of 0.05 % at 116.4 watts, which is 83% of the rated power at that level of distortion.
