I would start by contacting your cable provider. They should supply it free of charge. If you had to or wanted to purchase on your own, I would suggest (a) googling the item as you may be able to buy online and/or (b) visit a brick-and-mortar store that deals with electrical and electronic parts, possibly even something like radio shack.

I have contacted my cable company they are coming out to do a line rework on my Internet, they said their is a possibility that there is signal leakage.

Would my Dish also need an Isolator even though it is not connected in the same way?

I'm not entirely sure as I haven't had personal experience with Dish/Satellite. Given the hum issue you are stating, I would suggest that before considering any modification to your Dish setup, determine (or at least try) if it is causing the hum. This could mean disconnecting electric power to it, wireless and any hard wiring from it to whatever it ultimately connects to inside of your home. Then listen whether or not the Super Sub has any hum. If you are able to demonstrate that hum comes-and-goes depending on what you do, inform the Satellite dish provider and they should be able to remedy the issue.

Generally - but not always - low frequency hum is related to a lack of proper electric grounding. But keep in mind electrical current is not only available from a standard A/C wall outlet. It is also available in video transmission lines and those lines usually utilize the same grounding as you have your standard electrical power lines using. This tends to be the default way companies that offer audio/video do business. Only if there is a legitimate need will/can they bypass your grounding in favor of their own grounding or other solution. The drop isolator does not 'fix' the root cause grounding problem. It, as the name suggests, "isolates" the problem and in so doing the problems caused by not isolating (hum, etc.) becomes moot.

When the Sub is on and no volume or low volume you can hear a slight hum out of it. I also switched input cables with no change. I also had the input disconnected and the hum is still there. Is there a fix to this problem I am experiencing?

We've had a few more complaints about hum and it appears the problem may be with AC orientation in some installations/locations. To test, put a non-polarized cheater plug on the AC cord and reverse the orientation of the power cord in the outlet. If the hum goes away, you're all set. (If you don't like using the cheater plug, unplug the AC cord, remove the amp panel and reverse the black and white wires on the back of the AC socket - understanding that you may have to reverse them back if you move.)

That was the problem its as silent as can be now. Thank you very very much for the quick response and solution to the problem. Very impressed with the level of customer service at all levels!!

I've had the same issue in my SS XXL, but it hasn't bothered me all that much. Is it not unsafe to use a cheater plug like that for this device? If not, then I may give this a shot.
