"...so it is our opinion that it will be fine to use in a home theater in most cases"


It's too bad that page does not list the .cal file for the latest RS model mad.gif

If you read the post here you'd see that virtually every RS calibration file i've seen is inaccurate.

Speaking of the Radio Shack SPL meters, which one is the most ideal model to get for setting and measuring SPL levels for home theater type usage? Which model? Digital or analog?

Neither are in production anymore. This is the only one available from RS. I've yet to see it tested.

This thread. There are also large variances within the RS mics as some use different capsules.

Ok thanks. So in the absence of getting a calibration you are saying I am better off using REW without any calibration file for my particular model?

Well, that worked for the newer batches I tested of the 33-2055, but not the latest one they're selling, which is at this point untested. If its using the same internals, sure, but who can say.

Notnyt,
Is there a chance you can compare the Umik with Cal files and just C-weighting with it? I am curious how close they would be.

Can cross-spectrum calibrate any mic? I have a radioshack 33-4050 spl meter and wondering if that could be calibrated? If so, is it even worth to calibrate that spl meter compared to something like the UMIK-1 or Dayton UMM-6?

Just comparing a measurement from the Umik with the cal files and then with just C-weighting. My Behringer mic cal files are real close to just adding C-weight to it. I like the mic but I am looking for something to run with spec lab and cal files are no good as of yet. Ironmike was researching it and if I can load cal files then I need nothing.

I posted a graph of the calibration on the umik earlier. It's nowhere close to c weighting.

Cool but no good for spec lab or I would have kept mine.
