It is fine as is, the UMIK can measure up to 130dB, so signal levels are lower at normal test levels.one thing I've noticed is the "dB FS In" is really low, ~ -36. I haven't figured out a way to get it up to the recommended -18. Mic mixer volume in Win 7 maxed out at 100 and input volume maxed out at 1.00. Does dB FS In need to be -18 or is -36 ok?
It could be differences in calibration methods and mic orientation. To be more precise I should use the orientation for which the mic is calibrated... and I did not give that much thought at the time... all were at 90°. I think I have two files from Herb on my ECM8000... one for 0° and one for 90°, if I am remembering correctly. Of course I can't hear 10kHz very well anyway, so for me it would not be significant.Thanks for that !
That difference of @ 7.5db at 10K is quite significant ( & very much in keeping with what Herb recently discovered when comparing his calibration vs P.E.s, for the same UMM-6 microphone ).
