Re: MiniDSP UMIK-1 Microphone

The mic serial number is in the cal file, would have to ask MiniDSP to find out what happened with the batch that had incorrect data.

@JonhM, i'm from Europe, so i cant order from cross labs (with taxes if would cost 3x more).
I'm in Italy, I've bought (9) nine UMIK-1 from Cross Spectrum, perfect service, only 7 days to receive the goods.
I've paid less of 90Ä (UMIK-1 + calibration service + shipping + VAT + customs duty).
I will order, in the future, for my friends other products from Herb.

I dont know if the dirac version has a file calibration to be used with their software, or its calibrated to the specific mic.
All the UMIK-1 have a "calibration files" which can be downloaded from MiniDSP website. The UMIK-1 sold by Dirac is the same as the others.
P.S. The problem, my problem was/is (MiniDSP is trying to solve it...) that I need/want also the MiniDSP calibration file (in addition to those made by CS).

Thanks @Esprit.
My experiences with Portuguese customs are not that great, so i opted for ordering for German store.

Is HDMI required to use with the UMIK-1?

No.
When using the umik-1, is it better to use the jack outs, or a optical output?

Can use either, analog outputs don't usually suffer from roll-off within the range of interest for audio measurements.

Re: MiniDSP UMIK-1 Microphone

But is one better than the other?
Is analog preferred over the optical? Or the opposite?

Re: MiniDSP UMIK-1 Microphone

Dear All,

Following Chinese new Year break, an update is in order with regards to these 100 corrupted calibration files noticed in the previous post. We just had to wait for one week for our supplier to be back from their holiday break. As mentioned to Silvio (Esprit) separately, we're not trying to dodge the issue nor trying to sell a "hoax". Mistakes happen. :-)

The files are now updated correctly on the server and for those of you wondering what happened (before too many theories prop up..) here is a little summary. :-)
- Each UMIK-1 is calibrated on the factory floor at the last step in a quiet room. That's done from a measurement software similar to REW, just automated platform (AP).
- A second step is required to build .txt files that are matching our proprietary format (sensitivity/freq..). That process is a script (code) that takes measurements files and turn them into properly calibrated files. The process is done as a whole batch. One by one would take days... :-)
- That's the last step where our supplier had a bug that caused the issue for 100 mics during batch of December. The good news is that it's a bug in the last step, it's not a bug in the measurement.

On our side, our software team has now been putting in place some scripts to check each calibration files we receive and insure we don't have some issues (checking one by one not being valuable).

Hoping this clarify, thanks for your support as usual and have fun with REW!

Re: MiniDSP UMIK-1 Microphone

Keep in mind, the time difference and errors in translation, when you make a comparison between a Company in Asia and a Company in U.S. Not to mention the unknown number of employees dedicated to handle each operation and the unknown number of operations assigned to the unknown number of employees handling all the unknowns.
