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
