I finally got around to trying out REW and although I'm still unclear on a lot (especially the check levels) I thought I did everything correctly but after the first measurement something was obviously wrong. I have an auzentech prelude and am running vista. I'm using 3 meter Y cables with 3.5 on one end and 2 RCA's on the other. I have the radio shack digital meter going to the line in and the front left/front right going to the right vcr input on my receiver. I followed the guide and ended up with the measurement below. Anyone have any ideas of what I can try?
