I am finally doing my BFD calibration using REW and I am finding that I have to turn my sub-out level on my AVR all the way up in order to meet the "set input levels" on the BFD setup guide. The question is as long as I do not clip is it important to set this based on the guide? My subs are not easily accessible and I fear that I have them turned up "level wise" that if I turn up the sub level out on the AVR I will have too much input level to the subs. Right now the BFD input level seems to only go up about half way, never entering yellow or red level (clipping). If I have to I will adjust the subs but right now they are about 1/3 level.
