5.9.1 Equalizer-Setup
The two Filters can be configured in multiple ways in order to cover as most as possible applications. Both filters
can be programmed to be either in the front- or in the rear-path, respectively. This feature enables to have e.g.
the High-Filter in the front- and both filters in the rear-path.
