Re: Cross-Spectrum Microphone Calibration Service - USA

Hi Herb,
I've got 2 pre-USB Behringer ECM8000's!
1 w/o a cal file bought in mid-2008, then 2nd from you via CSL bought late 2010.

kinda getting tired of the whole mobile-pre & loopback thing when doing measurements, so possible time for me to get a USB mic, ha my 3rd mic.
Any discount for a repeat buyer?

Mike R,P.E.

Re: Cross-Spectrum Microphone Calibration Service - USA

Well looking at CSL site appears the UMM-6 has issue with noise floor that the MiniDSP UMIK-1 does not, hence I'll get the MiniDSP UMIK-1 .

Herb - is the MiniDSP UMIK-1 noise floor confirmed on par with 30-40db of my ECM8000?

What is the down side?
There are two issues we have discovered with the UMM-6:

• The UMM-6 microphone has a relatively high noise floor of about 53 dB, compared to a noise floor of 30-40 dBA for the ECM8000 and EMM-6. This noise floor can cause issues with distortion measurements or measurements of quiet sources.

• The microphone may not work properly with software that expects the input device and output device to share the same clock source (for example, ARTA has issues when averaging multiple measurements with the UMM-6).

Re: Cross-Spectrum Microphone Calibration Service - USA

The UMIK-1 noise floor is on par with the ECM8000 noise floor (and slightly higher than the EMM-6 noise floor). Bad news is that I'm out of stock of UMIK-1 and since MiniDSP is also out of stock, I may not get any more until sometime in January.

No, no they are not! I had a few left over from the last batch that I'm releasing to folks who had expressed an interest (and for a couple of warranty exchanges), but once these are gone that's going to be it for at least a few weeks.

Re: Cross-Spectrum Microphone Calibration Service - USA

It's okay, it's just that I've found that words on these forums tend to spread quickly and I want to head off the inevitable deluge of "I heard that UMIK-1s were in stock, but the site won't let me order, what's going on??" emails.

Re: Cross-Spectrum Microphone Calibration Service - USA

Okay, MiniDSP informed me that a shipment is on it's way and should arrive mid-next week. We're taking pre-orders now and should start shipping by the 15th (hopefully sooner but I want to allow some cushion in case our consulting business flares up).

Thanks for your patience.

Re: Cross-Spectrum Microphone Calibration Service - USA

There is a lot of information out there, these seem quite popular, so sorry if you answered this else ware. I was wondering how difficult is is to switch between the 90°, 45°, and 0° modes? Do I need to load a calibration file for each one and switch between them depending on use?
