The chart shows the analog signal flow from the input jacks to the output jacks. 11) If the output levels are the same check the power out stage at the speaker out jacks. 12) If you find the levels at the speaker out jacks are OK, your problem will be in the DSP part of the receiver. Congratulations! You have now eliminated 90% of the electronics in the AVR and confirmed that the problem is in the DSP section.
