Performing A Dirac Live Room Calibration
Select Recording Device
On the next screen you will be prompted to select the calibrated measurement microphone you
wish to use. The calibrated microphone and digitizer set provided by Emotiva will identify itself
as "Microphone (USB PnP Sound Device)". If you have purchased a different third-party calibrated
microphone then you should select it instead.
After selecting the correct microphone by highlighting it, click on the button directly underneath
it to select the calibration file that goes with it. (In a previous step we had you copy the calibration
file that goes with the microphone we provide to a convenient location.)
Note: Always be sure to use the specific calibration file that has been provided with the
microphone you are using. All of the current batch of calibrated measurement microphones
provided by Emotiva use the same calibration file - and each microphone is individually tested
to ensure that they fit the calibration curve it contains quite closely. With some other brands
of microphone a separate calibration file may be provided with each individual microphone.
In either case, using the wrong calibration file, or simply not using one at all, will result in
inaccurate results.
Note: The internal microphones included on many laptop computers are often extremely
inaccurate and are NOT appropriate for taking system calibration measurements.
After selecting the proper microphone calibration file click the button labelled Proceed To
Volume Calibration.
