The subwoofer output on my Kenwood VR-606 has suddenly stopped working. I have tried the "setup" several times, turning the subwoofer off and back on. Also, when I first power up the system, it emits a low...


It sounds like the problem is not with your VR-606. If you hear a hum from the sub, the problem is more likely to be in the sub's built-in power amplifier. However, it is worth resetting the amplifier to factory presets. To do this, unplug the power cable from the mains supply and reconnect whilst holding down the power on/standby key. If the hum persists, connect any powered speaker to the sub-out socket, power on and listen for the hum. If no hum then suspect the powered sub amp. Turn the sub on with no connection to the Kenwood VR-606. If hum persists, the sub has a problem and will need to be replaced or repaired. By the way, you said there is a low frequency hum through the 'speakers' for about 30 mins. Is that all speakers or just the sub? Hope this helps.
Cheers, Don.

Midiland 8200 (ADS 4000 controller) 5.1 hum problem


You may have an earth loop problem. This is caused by connect various equipment to different mains power outlets.
Connect all the PCs, audio and speakers to a single mains power outlet, use a power board so they are connected to the one mains power outlet.
I suggest you use a power board that has a built-in surge protection.

Annoying hum from speakers w/system off


The big electrolytic capacitor(s) in the power supply. The filter out the 50/60HZ hum in the mains, so you could be hearing the mains hum!

Older Harman Kardon computer speakers have loud hum


The hum (50 or 60 Hz) is caused by the AC power getting into the entry point of the amplifier. Either the filtering capacitors from the powersource of the speakers have dried up - replace them - or there is a short in the cables.
There is another possibility: if you have kicked the subwoofer  box its transformer might have slipped from its fixings and now is touching the subwoofer speaker frame.
The only way to find which is to open the cases.

Constant hum from speakers


It sounds like you might have a grounding issue. Try connecting to the wall outlet with a ground prong lifting adapter. Not just the speakers but the source plugged into the speakers also. Good luck.

Humming speakers


If you disconnect the signal leads and the hum is away, it's probably a groundloop problem, or your equipment is generating the hum.
If it does not go away, the amps are defective

Pioneer Receiver SX-750: Getting a loud hum through the speakers


The hum you hear from the speakers and from the unit itself originate with 60hz AC power. They may not actually be related. Sometimes a transformer will hum slightly and unnoticeably. That you're getting a loud speaker hum says there is an electrical leak or a grounding issue somewhere.

Do all sources produce the hum or, say, just the phono? How about on headphones? Try rotating the AC plug. In those days they weren't keyed with one large blade as they are now.

Hum in speakers


Unplug the minijack from computer to hear if it still hums. If not test speakers at another computer. if it works fine on other computer the sounncard is generating hum noise. Common problem is usually the earthing cable inside the minjack that is touching L or R speakerwire due to bending of cable and breaking off insulation. If youre up to it cut off minijack if its moulde and resolder a new one on.
