Re: Cross-Spectrum Microphone Calibration Service - USA

My apologies, but I just started a three-week period of travel and I don't have a lot of free time.

Reagarding confirmation of fized issues with the UMIK-1, what specific issues are you referring to? For the UMIK-1 we only offer Basic+ calibration level. Regaring noise floor, the older UMIK-1s have a noise floor of around 50 dB meaning that you're measurement needs to be at least 10 dB higher to give meaningful results (probably 20-30 dB higher for waterfall measurements). THe newer UMIK-1's supposedly have a lower noise floor but I haven't had a chance to test that out.

You should be able to find shipping prices on my site.

Hi,

Well I read about issues with the accuracy of the mics. It used to be a problem apparently. So you're saying that's not an issue anymore.

I'll take a look at the website for shipping. Thanks.

There is no mention of shipping prices on your site, at least that I could see. All I get is a $95 including shipping with the UMIK-1, but I assume that isn't to South Africa.

Define "accuracy". Even with an elevated noise floor these mics are quite accurate for measuring frequency response. It is only an issue when doing other kinds of measurements like THD.

There were bad batches. I remember there was a thread about it. It was a problem, but this was several months ago.

It's linked from the "Pricing" tab. The link goes to:

http://www.cross-spectrum.com/measur...-shipping.html

You can also get it from the shopping cart, by clicking on "change" in the "shipping and handling" area.

Not sure how I missed it. Feel a little embarrassed now. Thanks for pointing it out for me.

Re: Cross-Spectrum Microphone Calibration Service - USA

FYI: someone on the MiniDSP forum measured the noise floor of the UMIK-1 and found good results (29.1 dB(A), 43.1dB(unwheighted)). I guess that makes the warning on the Cross-Spectrum labs website about noise floor obsolete.

Re: Cross-Spectrum Microphone Calibration Service - USA

The webpage for the UMIK shows that they're available and will ship next week, but when I try to check out, it's telling me that they're sold out.

I tried clearing my cache, and using a different browser, but I still get the out of stock message.
