I just bought the digital SPL Meter at Radio Scrap yesterday. I took some readings using the internal test tones and everything seems fine (I didn't even have to change anything in what I had already set, except the master volume, every thing was 75dB) Then I tried the THX test tones on the TPM DVD and they were way off. So now, I'll need AVIA to have a proper reading. Also my TV has way too much overscan so AVIA will be handy for other stuff too... So is there any place I can get this disk in Montreal? Or order it over the net? FOR A DECENT PRICE?
