Question about Cambridge Soundworks P200 Subwoofer
This can often be described as "ground loop hum." Which essentially means that the circuit providing power is not properly grounded at the electrical and/or signal source and it introduces noise.
If it is connected by a coaxial cable, move one end of it's terminals by twisting it while it is plugged into the connector. If it produces static or the hum goes away then it is the coaxial connection of the end you are twisting...it is either not tight enough or seating in deep enough, or it is a faulty cable. If none of those testing methods suffice, try plugging the subs' amp into a different outlet, or, into a surge protection device with noise canceling circuitry such as made by Tripplite. Other sources of the noise can also come from the amp being powered by the same house circuit as such things as your refrigerator, fans, fluorescent lighting, microwaves or any device with an electric motor.
