Driver Correction

Driver Correction
The DSPre is able to correct the frequency response in terms of amplitude and phase.
The HOLM Acoustics approch is to measure each driver section in an extended frequency
range. This characterization of the components creates the basis for a correction. The
driver correction is optionally and can be switched on/off for each component.

Extended Range
When characterizing the drivers it is necessary to have an extended range without equal-
ization. The extended range let you measure a datasheet for each driver. Guideline for
frequency intervals:
