I have none of the other speakers plugged in and it doesn't matter if they are or not but i get this very loud humming noise from the main sub unit whether or not i have input cables in it. I have tried turning down volume and plugging it into different outlets but still nothing.
It is sad your having a problem with your
Benwin 5.1 surround sound system
If humming can be heard on all speakers, then it could probably
be on the power supply.
If it is only on the main SUB unit, then it could be the amp itself.
But check for power supply capacitors that supplies voltages to the
amps.Check for amp output DC voltages too.

It is merely degradation of the connection. Try unconnecting the speakers, cleaning the tips a bit, replacing them in, removing, recleaning, and then replacing a final time. This should get some scoring off of the connection... Aside from this, a new set of speaker wire is the best solution but just let me know what you decide on! Hope this helps!

you should check the outline ctrl..for a mic...it could produce a noise...if you have your speakers connected to pc...check the position of the plugs and the volumen of mic put in down...

I would imagine that your system has a fan installed to ensure the device does not overheat.
If this is a new device I would call the place your purchased it from and enquire if this is normal.... As there could be a fault with the fan or the temperature sensor.
If this is an old unit its possible that dust has covered the insides of the device and has caused the temperature to rise, thus causing the fan to spin quicker to attempt to lower the temperature. I would recommend taking it to an authorized repairer in your location to have them perform a clean / service.
