Sub hum when I hooked up cable

[bmccord]

Hey all, have a new delima. I have searched the site and got an answer, for the most part, but wanted to run my solution by you all. As I had my set-up previously wired, I had no hum. Then I hooked up cable TV to the system (new house, hadn't had it yet) and upon first power up, both subs ahummin. So, there is my snswer already. Unplug the coax fromt he wall and no hum. Now this is my question. Will a DAYTON VIT-1 VIDEO ISOLATION TRANSFORMER part number 180-075 fix it. It is a standard 60 Hz hum fromt he cable tv coax. Has anyone used this part with success? Thanks all. The part is only 10 bucks and I am wondering if I am going to need a more high tech peice or is that it. Thanks.

I've used it and it worked for my issue, which sounds similar to yours. However it is quite fragile and broke (separated F connector from the body), so place it somewhere in your setup where it will not get tugged on.

I think i will just put it on the input side of my monster power conditioner deally

I had the very same problem you do.

I got a Jensen VRD-1FF Cable TV RF Isolator, and everything is DEAD QUIET now. It looks and feels like a very solid and well designed piece. The cheapest I could find it, was http://www.markertek.com/SearchProduct.asp?item=JEN%2DVRD1FF&off=17&sort=prod for $49 plus shipping. I got in 3 days, no hassles.

Good luck.

I had a very simmilar problem, the fix ended up being $1.00. What was happening was my sub was grounded and i need a three prong converter that made it a two prog plug in, never had a problem since. I would try this first, even if it doesnt work its only a dollar.

That is NOT the solution. Your sub has a 3-prong plug for a reason. What you've done is circumvented the ground.

Safe? Not as safe as when it was grounded.

Dangerous? It's more dangerous than it was when it was grounded properly, but "how dangerous?" is arguable.

Jenson Isolator

I tried the Jensen VRD-1FF Cable TV RF Isolator (Cable provider is Cablevision) and it didn't do anything for me, matter of fact it filter out one of my HD channels. I ran an extention cord to my Power Filter (where all my AV is plugged into) and that took care of my hum.
