Microphone calibration file
Each UMIK-1 measurement microphone is individually calibrated to ensure accuracy. To
download the unique calibration file for your microphone, go to the
UMIK-1 page
and enter your
microphone's serial number. It is in the form xxx-yyyy and labelled on the microphone. Use
"Save As" in your browser to save the data to a text file – for example, UMIK-7001870.txt.
Then click on the
Load File
button and select your calibration file.
Once you have verified that this screen is correct, click the
Proceed
button.

Output & Levels tab
On the
Output & Levels
tab, set
Output volume
quite low. If you have another volume control “down-stream”
of the DDRC, set it about halfway (or -20 dB if digital) and increase it later if needed.
Click on the
Test
button for the left channel and gradually increase the output volume until it is at a moderate
level, such that your voice would have to be raised to converse with someone sitting next to you.
Now increase the
Input gain
slider
until the blue bar on the level meter reaches up into the green section, as
shown below.
Click again on the
Test
button for the left channel to stop the test signal. Then click on the
Test
button for the
right channel. If necessary, adjust
Input gain
or
Output volume
so that both channels are in the green.
When done, click the
Proceed
button.
