I am about to send out my Behringer UB1202 pre-amp/mixer to have it and my microphone calibrated for the purpose of speaker testing. What do you suggest I do to make sure my equalizer pots don't move after the calibration. I would think that any change to the equalization would invalidate my calibration.
You would modify the mic channel you are using to bypass the EQ stage.
I don;t recall on that one, do the EQ controls have a center detent? If so, that would be a reasonable protection.
How does one calibrate a little mixer like that? other than the user controls, it has no adjustments. Or are you getting a response curve drawn or something?
The line channels have no EQ, I believe. You might use one of those, but you'd need a mic pre. And if you had a mic pre, then you wouldn;t need the mixer.
Where are you sending the output?

Thank you for the reply. The calibration is in the form of a file that then gets input to your measurement software and the software adjusts your input based on the calibration file. I am using Soundeasy which uses my computer's sound card for input and output. I am using the mixer for a mic pre-amp only. According to the schematic in the owners manual, the equalizer is included in the line outs. The equalizer knobs do have detents, and I may rely on those for protection.
