Go no further. At this point you will need to use the charts to see w her e 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 eliminat ed 90% of the elect ronics in t he AVR and confirmed that the problem is in the DSP se ction.
