I got a noise floor of 35 dBA using ARTA and an external acoustical calibrator. The 1 kHz (and harmonic) spikes are definitely gone.
Good to know. I guess this is for the 3rd batch of mics from serial 700-0540 onwards?

Re: MiniDSP UMIK-1 Microphone

The one I tested was 700-0699 but I presume the results would apply to the whole third batch.

Re: MiniDSP UMIK-1 Microphone

Sorry I did not read the whole thread but does that mean one does not have to get the UMIK calibrated?

No. Noise floor has nothing to do with frequency response. What we were discussing was that some early batches had elevated noise floor issues that have now been fixed. It shouldn't matter to you unless you're doing special measurements that are affected by noise floor, like harmonic distortion measurements.

Congrats! Did you get it from Cross Spectrum or not?

Re: MiniDSP UMIK-1 Microphone

Just ordered mine - this will be interesting to compare to the bigger/older BK setup that I've used in the past.

Here's to reliable, new, & simpler

Thanks Anechoic!

Re: MiniDSP UMIK-1 Microphone setup issue

I'm new to this forum so please bare with me. I recently purchased a UMIK-1 and can't seem to get it going. I posted my problem up on the minidsp forum site but haven't gotten any responses in a couple of days.

I've calibrated the SPL meter in REW with an external SPL meter and all looked well but when I go to perform tests it seems my system needs to be much too loud to get -25 db input to REW. I've tried the set levels but my input from the UMIK seems much too low for the volume my speakers are putting out. When I get it loud enough at my listening position to satisfy REW's -25db input my system distorts badly from the wave that REW generates. I have a rather loud system that shouldn't have any problem hitting 75 db at the listening position.

From the little bit of reading I've done in this thread I take it I should mention that I'm using the analog out of my laptop. I have an HDMI out but my system is analog only so I'm stuck with that.

Any ideas on what's going wrong?
