I have the Integra 5.2 receiver with DPLII. I have Video Essentials Disk. Now my Integra receiver Master Volume goes from 0 to 79, 79 is the Max on the receiver. I have all my speakers set to 0 and the Sub set at -12. Now what is my refernce level?. The refernce level can't be 0 becuase when I set it to 0 no sound comes out and I can't set my speakers to 75 db on my SPL Meter.Also I have a feature on the integra called Intellivolume has anyone heard this feature, it goes from -12 to +12 it make the receiver louder as you go up in DB. I have the Intellivolume set at 0. What is my reference level. What I do is raise the master volume to like 60 db on my left front speaker and I get a reading of +1 on all of my speakers including my rears that doesn't sound right. My Front speakers are 8 feet aswell as the center and the rears are 9 feet in distance from the main seating position. When I had my Pioneer Elite my refernce level was 0. Can anyone help.
