I'm not sure how to calibrate the speakers through the Yamaha rxv-800. I've got the sound meter and Avia, but what I can't figure out is when I am playing a test sound from Avia (let's say the left main), how do I use the Yammy's controls to get the desired level out of that speaker? For example, let's say that the test sound is at 80dB and I want to set the LM speaker to 85db, I've been simply upping the Yammy's volume dial to 85dB. Now I follow the same procedure for the other speakers. But when I give this procedure some thought, it seems to me that I'm not really "setting" the sound output for each speaker correctly as all I am doing is raising or lowering sound output for each speaker - but I can't see how this "sets" the volume output for each. Again, test sounds per speaker via Avia playing on BD85, which controls on the Yammy allow for setting volume while listening/watching Avia? I just re-read this mess and now think I may have a better understanding of what to do. Please check me out. As I run the test sounds for each speaker, I am to TAKE NOTE (ie, write it down) how many dBs that speaker needs to be adjusted to reach the targeted sound level. Then go into the Yammy and adjust the dBs for each speaker. If I am right about this, my next problem is just where in the rxv-800 manual (http://www2.yamaha.co.jp/manual/pdf/av/english/re/RX-V800kai.pdf) do I find how to do this?
