I have measured the voltage coming out my amplifier at 2.8V. driving a double 15 hornloaded bass bin.with the umik1 microphone 1m away I am expecting something like 102dB. REW is saying 148dB! What is wrong?

calibration file starts with
"Sens Factor =-.8599dB, SERNO: 7043288"

should the quotation marks be there or does that make REW ignore it as a comment?

I have read elsewhere that the file should start with a line such as:Sensitivity -12.34 dBFS

Is this related to the sens factor? is the 12.34 figure correct for all umik1 or is it unique to each mic?

I have seen mention of internal dip switches - could these be set incorrectly?

Something is indeed odd here.. :-) Not sure what it could be but it does sound like a misconfigured gain or such or improperly processed cal file by REW. 
Either ways, easiest to just open a support ticket with our team (support.minidsp.com). We'll be here to help.
