Sorry I don't understand... why the mic need a calibration? It's not perfect yet?
Look a few post up and see how much individual mics vary that are suppose to be the same. Yes, they're not perfect and require a correction file preferable for that individual mic. With the generic files, you always wonder just how far off you are actually reading.

Impressive.... For "home calibrations" is recommended anyway?

Question Re: Cross-Spectrum Microphone Calibration Service - USA

Does the ECM8000 Premium+ come with a calibration file compatible with REW?

Yes, all my mics (including the Premium+) came with cal files that can be used with REW and many other software packages.

I'm running a special right now and I have a few left. They should ship during the week of Feb 28. If you need something sooner, you can get a mic a the normal price.

Re: Cross-Spectrum Microphone Calibration Service - USA

FYI, the last batch of mics I got included a microphone with a very unusual frequency response curve:



Because of this crazy response, I'm really not comfortable selling this mic at the regular price, so I'm selling it as a Premium+ model for $60 on my refurb page. You can download a copy of the full cal report (which also shows the polar response) before you order to make sure you know what you're getting. The mic otherwise works fine (sensitivity and noise floor within norms), it just seems like it's an outlier.

It will ship within 24 hours.

edit: it's gone.

Re: Cross-Spectrum Microphone Calibration Service - USA

I have a PartsExpress EMM6 that came with a cal file. I was wondering if anybody has had one of these calibrated yet and how much it varied? I was wondering if I should use that file or the averaged EMM6 file offered here? I'll probably get mine calibrated some time when I've got a few bucks to throw at it, but I was wondering what you guys would do in the mean time.

Re: Cross-Spectrum Microphone Calibration Service - USA

Use the curve that came with your EMM-6, it will be closer than the average curve here. The individual EMM-6 curves aren't bad, and they seem to have improved some with the latest bunch.

Ok thanks for the reply. Thats what I figured but it doesnt look much like any of the ones that constitue the default/average graph, thats what made me want to ask.
