Analog Receiver/Processor – Speaker-Level Connections Use this installation method only with an analog receiver/ processor that does not have digital processing or bass management, and also does not have a subwoofer output or a volume-controlled preamp (line-) level output: Connect the speaker wires for both your main left and right speakers, and for the subwoofer, to the same speaker terminals on your receiver or amplifier.
Analog Receiver/Processor – Line-Level Connections Use this installation method with an analog receiver/ processor that does not have digital processing or bass management, and that is equipped with a full-range subwoofer output or a volumecontrolled preamp (line-) level output: Use RCA-type interconnect cables to connect the linelevel subwoofer outputs on your receiver or amplifier to the line-level inputs on the subwoofer.
OPERATION Power When the unit is plugged in and the power switch is on and no signal is received, the LED on the top of the unit will turn red. When a signal is present, the LED will turn green. Note: It will take several minutes for the LED to turn from green to red after the input signal to the subwoofer is removed.
Phase Control The Phase Control determines whether the subwoofer’s piston-like action moves in and out in phase with the main speakers or opposite the main speakers. There is no correct or incorrect setting. Proper phase adjustment depends on several variables such as subwoofer placement and listener position. Adjust the phase switch to maximize bass output at the listening position. Remember, every system, room and listener is different.
