Hey everyone! I have had a problem for a while but am just now getting to trying to fix it. Does anyone else notice a different tone for the Center channel when doing the test tone for channel levels? My FL FR RL RR all sound the same with a high pitch static. The Center however has a much lower and duller sound, but about the same volume. I have consistently had issues with the Center channel and sound of dialog. I have tested this with my normal settings, after microprocessor reset, multiple speakers and its always the Center channel. It also seems now that after the latest Microprocessor reset to try to remedy this issue the AVR is now not decoding the signals correctly. Now I get just 2 Channel stereo where I used to get DD, DTS HD-MA, DD TrueHD. All I have done after the latest reset is setup all speakers to small, set crossovers ALL to 80Hz and setup inputs. I avoided Audyssey due to the fact that it has never sounded correct no matter how precise I tested, following all the help on this forum and also on the Audyssey website. I have owned many other "digital" AVRs and never had the Audyssey setup and they have all sounded better with only being able to set Distance, Spkr Size, Crossover Frqcy and Tone. I am not dogging on Audyssey, it is a great technology but it has consistently given me poor results and readings and I personally think that if some of the most advanced AVRs out there that sound great dont have Audyssey, I should be able to manually configure the AVR-3310CI and it sound comparable. Any help for any of you gurus would be much appreciated.
