Anyone notice that the calibration file format on the new batch has changed? The recent batch of UMIK's only has calibration file values down to 20.1Hz and then it just ends... in addition about half of the UMIK's in this batch apparently experience a large step going from 802Hz to 812Hz, the other half don't exhibit any such 'step'. Anyone know why that is? Was the calibration procedure changed? and why do the half of these new UMIK's, the one's exhibiting this large jump, happen to be between the exact same two adjacent frequencies (always between 812Hz and 802Hz)? Could it be due to different calibration 'test beds' possibly being used and one is messed up? Then there is the question of, if the UMIK is spec'd at +/- 1dB from 15Hz-20kHz then where are the 15-20Hz correction factors in the file? I've asked these questions on the manufacturer's forum and am still awaiting a response. Anyone here have any answers? Hopefully there is just some simple explanation...
I am following your question closely as I have not yet received my Umik-1 and expect it has similar calibration issues.

Follow the link I just added to my earlier posting above to see specifically what I'm talking about.

Here it is again for your convenience... submit Serial # 7000275 to see my UMIK calibration file... then submit a number below 7000188 to see what the older calibration files look like. Something definitely has changed...

Re: MiniDSP UMIK-1 Microphone

Your right. When I compare the 2 calibration files (yours vs prior) there are big differences. Your file starts at 20hz vs 5 hz for files below 7000188. I also saw your post on the Minidsp forum. Got to be a bogus file. Wait to see what they say. Perhaps there is a logical explanation.

Re: MiniDSP UMIK-1 Microphone

Did you check out some of the other serial number files from the new batch? Like 7000277 or 7000274 or 7000270... these are particularly bad... the worst in that decade of serial numbers (270-279)
Still no official word at all from the DevTeam over at the miniDSP forum... surely they've seen the thread over there. It should now be almost 2 o'clock Tuesday morning in Hong Kong by my calculations, so they had all Monday to see the posting and respond. Maybe they are sooo busy no one had the time to look at the forum on Monday OR maybe they are checking into it, which would not be a good sign because it means there's not a simple explanation and thus most likely no quick easy solution. The longer it takes to get a response from the DevTeam, the more worried I will become as to what kind of resolution might come out of this.

If you look at the miniDSP forum you'll see that they are holiday from Monday to Wednesday and you should expect responses to e-mails and inquiries starting Thursday.

Re: MiniDSP UMIK-1 Microphone

We'll that's interesting about the calibration only going down to 20hz. I hope there's an explanation for this.

Re: MiniDSP UMIK-1 Microphone

Yes I looked at some of the other serial # files from the new batch and they do look bad. Not sure what to say about it. I was notified today that my Umic-1 is sitting in customs so I expect delivery will occur shortly.I also expect I will have the same calibration file issue as you so I will also post a concern on their forum referencing your post as a reminder to sort this out asap.

I guess that explains why we have not seen a response.

Thanks for that!!! I didn't notice it... this eases my mind a little knowing that there still might be a simple, easy answer to all this speculation. So hopefully we can expect an offical response by Wednesday evening or Thursday morning.

Re: MiniDSP UMIK-1 Microphone

Attached are the UMIK files imported into REW to show them

I think the graph shows the correct data?

Hope this helps, looks interesting.
