I recently got a hold of an old radio shack meter (realistic 42-3019) its an analog meter. I turned on my test tone in the AVR and the AVR manual says to set to 75db, So i am assuming the signal is -30dbfs That seems to work alright, but when i go and stick in my disney WOW disc and run the audio tones. It never really says what to set the db to, (says to pick between 78-85) and then set the sub 3db higher. The WOW disc tones are definitely louder so i suspected it might be a -20dbfs signal, so i set the volume to achieve 85 db and i found my volume ended up being a few ticks lower than when i set the speakers with my AVR tones (volume at 64 with AVR and then it was 61-62 with WOW disc) Doesnt at seem strange? Then when i jump to the sub test tone on the WOW disc the DB readings go way higher (like 95-100db) So to wrap it all up, my AVR tones set my sub at about 3.5 on the dial on the back of the sub Then i keep the same settings and the disney WOW disc shows that as reading at least 10db louder then what my AVR tones are giving me. The bass seems abought right now, if i dial the sub back with the disney disc the sub wont be loud enough i suspect. Just wondering if something is amiss or if i am missing something here?? Also, ive found alot of radio shack SPL correction value charts, but do i really need to use that for pink noise tones??? IIRC pink noise has alot of frequencies in the tone??
