On the Bench (JEJ)
Measurements were made with two channels driven. Distortion bandwidth was 80 kHz.
IMD was 0.094% at 20 volts into 8 ohms (50 watts RMS).
THD+N vs. Frequency test results for 8 ohms and 4 ohms were fair. This receiver could probably drive 4 ohm loads, but with limited use of the volume control.
For THD+N vs. Power, at 8 ohms, distortion was low until 78 watts, then rose rapidly to clipping at 105 watts. At 4 ohms, it stayed low to 100 watts, then rose to clipping at 160 watts. This was with two channels being driven.
Frequency response was 0 Hz to 80 kHz, - 1 dB. At 4 ohms, the extreme end of the response dipped a bit, with overall response down 4 dB at 200 kHz.
