Hold your SPL meter as close as possible to the mic and "Set Measurement Level" (I prefer to set it to 80 or 90db).
hahahaha - that figures!

You really wouldn't have to load the .cal file for this. Hook up your calibrated mic and amp. Hold your SPL meter as close as possible to the mic and "Set Measurement Level." The SPL meter is simply used to set that level initially. You are done with the SPL meter then. You would then "Set Input Level", which will make sure you have your mic amp level set properly. Then "Calibrate" the REW SPL meter to your SPL meter. You don't necessarily have to have your SPL meter for this because you have already set the measurement level to 80 or 90db, or whatever you set it at. When you "Calibrate" the REW SPL meter you will adjust the level to the same SPL level you set during "Set Measurement Level".
Cool. Thanks!!!

Now... if you take a lot of peaks out during the filter setting, when you go back to measure the filtered response you will most likely need to "Set Meaurement Level" again because you've obviously cut the overall level in most cases by taking out those peaks. It won't (or may not) be loud enough as is to get a good reading. So you'll need the SPL meter once again.
I'm using a Rane PE17 for a parametric; do you have any tips for me on using REW and manually entering filters parameters into the PEQ?


My HT rebuild/upgrade is a neverending story!
