9) Proceed to the
measure
screen and hear the sweeps. When a measurement is successfully
completed you’ll see the frequency response displayed. While it’s OK to try things out with one
sweep, a good calibration uses more measurements.
If the volume is too low the calibration will fail for “missing samples" or “poor signal to noise
ratio”. If the volume is too high the calibration will fail with clipping. If the calibration run fails,
go back to the volume page and adjust the volumes. Also check that your speaker configuration
is correct. If you set up for 7.1.4 but have only 7.1.2, the speakers not present are “missing
samples”.
10) The Dirac Live® tool encourages you to run sweeps at multiple locations. We suggest you first try
a calibration with one location to become familiar with the process. Then do a calibration with a
full set of measurement locations for better correction.
11) Proceed to the
Filter Design
screen and see the correction that Dirac® suggests. You can drag
the left and right endpoints. You can investigate the right cutoff frequency for your speakers.
You can grab the dots to adjust the target curve. With Dirac Live Bass Management you can
drag the crossover point and recalculate. Dirac strongly recommends adjusting the target curve.
Their default shows a slight “tilt” to the low end, but must users want more bass. Maybe
something like this:
