Hi gang! Neo, that UMM-6 has turned out to be a reliable unit here, and Dayton's factory calibration figures are very good. One of my 2 Behringer mics bought the farm on a carpet drop. Thus, the other Behringer, ordered with the tighter calibration, is only brought out if in doubt about something. Day-to-day, the sturdier Dayton's calibration produces the same curves at up to 12db/octave, and still usefully similar at 24 & 48.
Wow, that Behringer UCA-222 looks like a VERY attractive proposition for $30. I was not aware of it. I've also found that many of the latest built-in sound "cards" in recent motherboards can do a terrific job on most practical measuring tasks.
I just hope that more folks keep getting the message that measuring SPL can be quite rewarding, not really hard and rather cheap, these days.

I actually have the UAC-202 which, I believe is the same as the 222 except for color. Here is a nice review.
I married the perfect woman. The downside is everything that goes wrong is my fault.
The Behringer UCA-202 suffers from bad channel separation in the bass. It can upset measurements. A friend of mine modified an UCA-202 in 2010 for better frequency response (lower output impedance and lower fu), it did not improve the channel separation.
Didn't know that, thanks. Actually when I do measurements I do one channel at a time and then have the REW average the responses. I typically use the DAC (Schiit Modi Uber) rather than the UAC-202, which I bought several years ago when I did not have a DAC. The main purpose of the UAC-202 now is as an ADC when I digitalize vinyl which is not that often.

Those Behringer units have a number of little issues/idiosyncrasies. :)
As an example.....one that might catch you in a testing situation is the multiplexed outputs. The left and right channels have a 25uS timing difference between them.
However, you can work around most issues with these units. The price makes it very attractive.
Dave.
