MEASUREMENTS

The following measurements show that the Optimizer´s phase response is very stable at high amplitudes.

The doted line in fig. 16 illustrates the frequency response from 0Hz to 200kHz for two combined equalizers (band 1 and 2). The solid line shows the phase reponse with only 2° diver- tion at 20kHz!

A broad frequency range has become a major demand for
