Re: Noobie with REW help with measurements


OK, I did not hit that set target level button before each measurement.

When going from one speaker to the other (right to left) I am finding that I have to change the volume on my pre-amp about 10-13 dB before REW says the signal level is good. then I do the calibrate SPL under the settings, and find that for one channel, the spl is at 80dB, but then the other it is around 95. So, this is normal? I should take the reading there, and use the set target level as you said?

Oh, and doing the calibration isn't as easy as you might think... The room is in my attic space (up spiral stairs). The pre amp and HTPC are downstairs in my equipment room. I must've hiked those steps 30 times last night...

One more thing on the HSU subwoofer (first graph) it looks like the level actually increases from 80-90hz, and doesn't really roll of until 100Hz?
