On the recommendation of this board's members, I went out and bought the Radio Shack SPL meter (the analog kind, no less) and just ordered the AVIA dvd online. I was playing around with the meter tonight and just trying with my receiver's test-tones. I think I'm using the meter properly (have it set for 80db, set to "C" and "slow", standing aside when I measure), but no matter how much I crank the volume on my receiver, my LR speakers never seem to get up very far on the meter. My center comes through loud and clear though and can reach "0" on the meter. My LR speakers always seem at lower volume. I checked to see if they were out of phase, but the connections seem OK (no pos/neg mismatches). **The goal is to get all LCR speakers to "0" on the meter, right? What am I doing wrong? Do I need to fool with the level controls for each speaker? Strangely, my receiver only allows me to adjust the db level on the center; I can only adjust the balance on the LR speakers.
