Ground connection
If there is a humming noise when using the subwoofer connected to the speaker terminals, connect the subwoofer and the receiver/amplifier with the grounding cable as shown in Illustration A.
*If there is no ground terminal (GND) on the receiver/amplifier side, connect the cable to a screw that fastens the top cover of the receiver/amplifier to the rear panel as shown in Illustration B.
