I have a subwoofer that hums when it is connected to my A/V amplifier.
Both unitw were repaired recently, yet the problem persists. I am at
a loss. The solid state amplifiers were replaced in the Pioneer
SA-HE200 amplifier. Only the powered subwoofer is effected; the other
speakers (front, satellite, center) function well. The amplifier in
the powered subwoofer was just replaced as well. I installed the unit
myself and hooked it up as KLH instructed. The subwoofer is an E-10D,
part of the plat-6 system. The interconnect cable is shielded and
uses gold plated RCA connectors. The problem is the same with the
unshielded cable delivered with the speakers. What do I try next?
BTW, music does play through the subwoofer, but the hum is louder. I
can also change the hum volume by playing with the subwoofer gain.
