Polarity. The Polarity button reverses the polarity of the input signals.
Power User Tip: Once your have connected your Sub 8BT to your system, try
experimenting with each setting while listening to your favorite music. Leave this switch
in the position where the bass was the loudest.
High Pass Filter. Removes frequency content below 80 Hz from the
full-range signal sent from the Sub 8BT outputs. This is useful if your
main studio monitors do not have their own high pass filter.
Power User Tip: Leaving frequency content below 80 Hz in full-range monitors can
cancel out or reinforce the highest frequencies that are reproduced by the Eris Sub 8BT.
This can make the bass response of the overall system muddy and ill-defined. By rolling
off your full-range speakers, you will create a more linear frequency response between
the subwoofer and full-range content.
Low Pass Filter. This control determines the upper end of the frequency range
reproduced by the Eris Sub 8BT. If you have enabled the onboard High Pass Filter, set
the Low Pass Filter control to 80 Hz. Otherwise, set the Low Pass Filter control to the
lowest frequency that your main monitors can reliably reproduce.
