Ok here is my setup: Panny XR50 receiver Point 5 MK II speakers Dayton TM II sub I tried following the calibration tips and guidelines but I am having trouble with the level on my amp. The guide says to turn up the main volume of the amp to 75 db. The problem is my amp won't go to +75 db. It will only go up to +0. I tried putting it at -75 but obviously its too soft for the SPL meter to detect. Anybody have experience calibrating with a Panny XR50 amp? For now I just calibrated by speakers at -15 db. The SPL meter when running the test tones from the DVE disc goes to about 74 db. Thanks and any help will be greatly appreciated.
