HPF applications
For HPF applications, HPF filter is available for additional processing after the speaker
control. It is a 2nd order butterworth highpass filter with selectable flat mode. Figure 22
shows the diagram of the HPF that includes an external RC network.

Output selector and mixing
The output-selector allows the front and rear speakers to connect to different sources. The
setup of the output selector is shown in Figure 24. A Mixing-stage is placed after the front
speaker-attenuator and can be set to mixing-mode. Having a full volume-attenuator for the
mix-signal, the stage offers a wide flexibility to adapt the mixing levels.
