Features
1 - XOVER IN / OUT:
Pressing this button engages a high-pass filter at 120 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.
