Loud Hum from Subwoofer

Hi everyone
I recently bought a Subwoofer System
But it produces a loud hum which can be irritating to one keen on the audio quality
Now I have tried conventional solutions like ensuring the system is on the same extension as the other home appliances to avoid grounding issue.
I have even tried the system in a different house, but still the hum is there
The subwoofer has four satellite speakers
Interestingly the hum is only there when the satellite speakers are connected
On disconnecting them, the System Produces no hum
The pitch of the hum does not change with any adjustments in volume
Even removing all inputs does not remove the hum

Try inline transformers from blue jeans cables. Worked for me

The above suggests you have an integrated surround system not a stand alone subwoofer. The fact that the hum is present when all inputs are removed and is not affected by the volume control suggests it is a fault with the unit. As the fault disappears when the four speakers are removed it is a bit odd but may just be part of the fault.

If the hum is still there when all the inputs are disconnected how will a connection cable help?

Hey guys
Thanks for your help
Since the woofers were within warranty, I returned and had them fixed
Now they are smooth, no unnecessary irritating humming
I am contented at the moment
