Home Video Asylum

TVs, VCRs, DVD players, Home Theater systems and more.

I found the same thing...

I recently had a similar experience (though my pre-amp test tones had actually led me to over-emphasize the center channel, not the rears). I was tweaking some video settings on my projector (built a new screen), and decided to check the speaker levels while I was at it.

Interestingly, the discrepancy between pre-amp tones and Avia's test patterns was mentioned in one of the intro videos; if I recall correctly, they claimed that their tones were broader-spectrum pink noise signals than most pre-amps/receivers provide, therefore giving a more accurate reading, as it interacts more realistically with the room acoustics. I'm paraphrasing, so I could be misstating, but that seemed to be the gist of their argument.
