Generally the hum is one of two things. If a sensor, pickup, per-amp, or mini-amp are too close to the receiver or speaker, Feed-back may occur or a hum and buzz join the audio signal out. The usual problem is: line in port on the instrument can be defective or the male jack is not making proper contact. If a cord is tested and working, the condition is in the input on the instrument. If a terminal has a loose wire inside the instrument the problem can be intermittent ( come and go) and thus a buzz or line noise may be present.
yes. A good idea. Kill power to the sub, then unplug and remove everything from the sub. go ahead and plug it in again and check for buzzzz.
That is test one. if you have buzz still, its the sub assembly. bad luck, but not impossible. If the buzz is gone its one of the signals to the sub. They can produce a buzzz without any signal coming from your stereo equipment. Replace the feed line, enjoy! BTW...Kef sure does sound clean. good choice.
'Buzzing' is not a good thing; it implies that filtration of the DC used by the output section is not as it should be.
Power supplies that are mildly overloaded can cause this or an abnormal current drain from one (or more) channels.
The odd problem with the back speakers does sound like a setup problem rather than a circuit failure.
Of course it will stop buzzing when you mute the speakers.
From the limited description, it could be anything from a power supply to loose wires in the system between the speaker leads and the motherboard.
Best bet is to take it in to a technician and get a pro's answer. If he wants to charge more than what it's worth to you, get a new one.
