HTP-1 Installation and User Guide Release 1.8.1
Calibration
Calibration is a critical part of good sound. The HTP-1 collects calibration items on the calibration page.
The calibration page contains a lot of information. This section describes each item to help you
understand.
In this example the “Columbia: Take 3” Dirac calibration is selected. It covers only 5.1 speakers. Hence
you see that the back speakers behave as if they were calibrated to zero. They are bypassed. The
calibration determined a -12.1dB trim for the subwoofer. The six dB of user trim shown here is one way
to experiment with the sound “to taste”. It’s not something that can be defended due to the physics of
the system.
The example system includes several Dirac Live Bass Control calibrations. These are indicated by the
asterisk after their name.
