22 OPTIMIZER
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
