Hi Id like some advice with an issue im having. What im using: A-860 aventage/ 100w richter speakers 7.1/ bluray source 7.1 so my question is this. I had this exact setup with my old pioneer avr. No issues sounded pretty awesome. Now. I upgraded to the above AVR. I have auto calibrated using ypao. I found the centre speaker volume level to be way too low. I manually set it at +4db in comparison to other speakers that are set at 0.0db or less. Its still way too low ?????? i generally use to have the main volume set at around -20db. Now with this yamaha i have it set at -13.5 db...just to get the same kind of volume? EVen at this volume and with the centre at +4db above other speakers.The centre is way way too quite. Its like i have to sit really close to it just to hear it ..then all of a sudden the other speakers will blast away at super high volume?? I dont get it..why would this be happening? why is the centre so damn quite ? LIke i mentioned, with my pioneer i didnt have this issue at all. Any help would be much appreciated. Also, does anyone know of any good tutorials for manually calibrating this AVR? Thanks in advance.
