10) IF THE OUTPUT LEVELS ARE NOT THE SAME STOP! Go no further. At this point you will need to use the charts to see where you are losing your signal. 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.
