    Hello,

    After reading lots of speaker reviews and reading how the reviewer calibrated to "Dolby Standards" I would like to do the same.

    The way I've been setting up/tweaking my rig is as follows:

    Set Radio Shack db meter to C weight, slow. Set dial to 80db.

    Turn up volume on receiver w/pink noise playing so meter centers on 80db

    Tweak all channels, except the sub, to read the same on the meter.

    Is there more to it than that?

    FWIW, I keep the sub at about three notches higher (on the meter) than the other 5 speakers. Having the sub play at the same level results in very little output from the sub.

    Thanks.

    We have a Primer/FAQ that covers a lot of this: Home Theater means Accuracy & Calibration

    Generally 'philes recommend 75 db (but I'm with you: 80db is easier to read on the meter). And the subwoofer should be 5-8 db louder.

    There is also a LOT of placement changes you can do with a sub to smooth out the room response. Search the Speakers fourm for "House Curve" to read about members who plotted their room response.

    OK, I scanned every post in the FAQ and there was nothing in there about calibrating. Unless I missed it....

    Lots of real basics for the real newbie...a good tutorial for the true newbie.

    Did I miss the calibration section?

    *edit*

    Yep. I missed it. It's this new mouse I bought...it scrolls REALLY fast. Yeah, that's it...the mouse. :b

    There's even a nifty picture of the R.S. db Meter. [​IMG]

    Hehehh...*slinks away behind the couch*

    Thanks, Jeff Gatie. [​IMG]
