• Adjustable frequency crossing points on all levels (Low / Mid / High).
• Independent output gain controls on all levels; +-18dB boost for low / mid / high outputs.
• 2/3 way mode switch.
• 180* Phase switch for low pass output:
Reverse the polarity of the right channel subwoofer wires when 180* phase switch is on.
• 20 Hz subsonic filter (18dB slope): This high pass subsonic filter will block all undesirable frequencies (under 20 Hz) from entering your amplifier and causing damage to tweeters and midranges. Subsonic filters will increase the efficiency of your amplifiers.

IMPORTANT: TO MAINTAIN EQUAL INPUT/OUTPUT VOLTAGE ON THE RCA LEVEL, GAIN CONTROLS MUST BE ON THE ½ MARK (MIDDLE) POSITION.
