Features
1 - XOVER IN / OUT: Pressing this button engages a high-pass filter at 110 Hz. This 4th order active filter allows a
smooth transition between the subwoofer and a full range speaker connected to the output connector.
2 - POLARITY INVERT: Allows you to set the polarity of the subwoofer to either 0° (no change) or 180° (inverse
polarity). The correct polarity setting will produce the best blend between the subwoofer and the full-
range speaker and the strongest perceived bass response at the listening position. This is especially
useful when the subwoofer is placed at a different distance from the listening position than the full-
range speakers. If the bass response seems weak, try inverting the polarity.
