Using the High Pass Filter

If you choose to use the high pass section of the Controller to roll off bass to your main 

speakers, you can use your measured data to select a low pass (LP) frequency. The suggested 

setting for the high pass frequency is at the point where the measured frequency curve begins to 

“roll off,” specifically at the frequency that is minus three to minus six dB (relative to the average
