Product Details

Cable Television Isolation Transformer

The VIT-1 virtually eliminates the 60 Hz hum introduced into your home entertainment system through your analog cable or antenna connection, and is usually noticed when connecting a powered subwoofer to your home theater system. A passive design does not affect your analog cable tv signal strength (not recommended for use ondigital cable or cable modem installations). In extreme cases the use of a grounding block may also be necessary. Connect the transformer in-line between your cable line and TV using the female F-connector on the cable side, and the male F-connector on the TV. Operating frequency: 54 MHz to 1 GHz.

Note: Interferes with digital cable, cable modem, and satellite TV operation.

Cable Television Isolation Transformer
Cable Television Isolation Transformer is rated 4.1905 out of 5 by 84.
Rated 5 out of 5 by from Just what I neededI was having ground loop problems with my home theater system and did a week of troubleshooting. Frustrated, I finally decided to order the transformer and received it yesterday. It took about a minute to install and the hum was gone in an instant. I give this product an A+ as well as the customer service. I highly recommend it to those that are having ground loop issues with your home theater system.

Rated 5 out of 5 by from Works just fineI discovered a slight hum when listening to my FM tuner. It shared the antenna with another receiver connected to my home theater system and apparently the is some gound issues between the two. This eliminated the hum problem.

Rated 1 out of 5 by from Dayton Audio VIT-1 Isolation TransformerI had a hum in my system, I installed it in the cable line going to my computer and it killed the signal to the computer and then so I removed it and installed it in the cable line going to my satellite box and it killed that signal also. I can't say it is good or not it just didn't work for me. I still have the hum.

Rated 5 out of 5 by from Did the trickWe had bad hum problems because we broadcast (just in our facilities) church services through an RF modulator and also have a cable TV connection in one of our monitors.This IT between the cable box and monitor completely eliminated all the interference.

Rated 5 out of 5 by from Subwoofer Hum is Gone!Thats pretty much it, had a hum before where I had to turn off my sub everytime I watched TV, installed this guy and the hum is nonexistant now. For me, it was totally worth the price I paid.

Cable Television Isolation Transformer

I do have a hum on my subs which goes away completely when I disconnect my digital cable. Would this product solve the problem or not?

Asked by: Bob M
Not. It is for use with analog cable only. It will block digital. I suggest you isolate the sub instead by placing this ... http://www.parts-express.com/wizards/searchResults.cfm?srchExt=MFG&srchMfg=0 ... Between the output of your receiver and the input of your sub. Good luck.

There is a disclaimer saying not tu use on digital cable; so what product should I use?

Some clients (I noticed on the newer comments, probably post digital) said they lost HD channels with this product. Is Tom saying I should go ahead and use it anyway? If so how (where to place it in the total line)?
Asked by: Bob M
You should not need a product of this type with digital cable. The purpose of it is to reduce 60hz hum in analog signals. Since you are digital, it is not analog and hence, you should have no hum.

If this product is for analog systems, what can I use for digital cable hum?

My sub has a hum only when the digital cable is connected. I tried two different ground loop isolators between sub and receiver and they lower the signal and flatten out the bass on the sub.
Asked by: Bob M
Although you have digital cable, the carrier is still the same analog carrier. This ground loop isolator will not notice the difference between a digital cable installation and an analog cable installation.
