I just calibrated my speakers on my new Yamaha RX-V657. When I went into the menu to set the test tones on my old Denon, it automatically went to 00 on the volume control. On the Yamaha, I had to turn the volume control up manually to 0. I set everything to 75db during the calibration so I'm assuming (uh oh!!) that when I'm at 0 on the volume control, I'm at 75db. If I wanted to listen at 85db or whatever higher level, the volume control would have to be set at +2, 5 or whatever # that would get me to that particular db level?? Am I thinking correctly?? Thanks....
