Isn't that strange? .

What is going on? Just as odd.....I have to add gain, you'd have to back it down 5dB or so, we're both using Macs that are well matched for gain on their lonesome.

Maybe I'm not crazy after all but I'll call them and see what gives. I suspect they'll say "don't worry: they all do that!" I will report back.

Added...I should mention that to get the actual reading (if you've got the filters set and operating), you'd want to measure at the Xover frequency. It's A LOT easier to just bypass the filters in the crossover though. In theory, gain should be the same on both legs of the crossover at the center frequency. It might be easier to just use broadband noise rather than a sine wave. Set meters to slow if you have the ability, (which the 452 does give me) should you want to measure gain with the filters active. But I think it's easier to bypass the filters for this measurement. Make sense?
