I calibrated my speakers (genesis 6.1 system) with the radio shack analog meter, C weighting and on the slow setting. I noticed there was no 75 db setting, so I switched back and forth from the 70 to the 80 db settings. It was interesting to note the readings were close, but not the same. Is there anyway to defeat the 700's internal test tone so you can use DVE on your dvd player? I notices the levels (between the avr700 and my pio 59avi running the pink noise test in chapter 9) are no where even similar. Any help would be appreciated!
