The Jensen Transformers
VB-1BB Baseband-Composite Video Isolator provides powerful 120 dB ground isolation, making it the perfect choice for video surveillance systems, or anywhere that high-performance ground-loop isolation is needed.
The VB-1BB is housed is a sturdy metal enclosure, measuring 3.45" W x 1.7" D x 1.5" H., including the flanges. The flanges have mounting holes, which are handy for permanent installations.
Please do not confuse the
VB-1BB with similar (but inferior) products. Jensen Transformers' ISO-MAX Studio-Quality Video Isolators provide the ultimate signal interface solutions. They solve the fundamental problems associated with ground loops, without degrading signal quality.
Also available with RCA connectors as VB-1RR.

With inferior products coming from all over the world, we think it is a genuine treasure to find a company like Jensen Transformers, actually designing and manufacturing some of the finest products in the world, right here in the USA, and we are proud to be able to offer their products. The VB-1BB is made in the USA, is backed by the manufacturer's comprehensive one-year warranty, and has a remarkable 20-year warranty on the transformer device itself.
It is a subject that is seldom discussed in manufacturers publications, or even in magazines of the trade, but ground loops can happen even in the most carefully planned A/V system. When ground loops happen in a video system, the result is unwanted hum or video hum bars.
For example, in video surveillance systems, the power supplies for the cameras are are typically powered by a different source than the equipment that is used to record and/or view the video.
When devices in the same system are powered by separate power sources, that can cause a difference in ground potential between the two pieces of equipment. It can be because one of the circuits is loaded more heavily than the other, or because one run is longer than the other, or any number of other reasons that are beyond the scope of this article, but the result of this difference in ground potential is commonly referred to as a ground loop.
The Jensen Transformers VB-1BB is elegant in its simplicity. In the example above one would simply insert the VB-1BB anywhere in the video path between the camera and the monitor. Immediately, the effects of the ground loop become a non-issue. Problem solved. There are not too many things that one can install in a video system that can provide so much improvement with so little effort.
Good cables are very important in the fight against hum and noise. You will need at least one short patch cable in order to insert the VB-1BB into your signal path, and you may want to consider upgrading your existing cable(s) as well. The VB-1BB does not include any cables, but if you need them, we have some very high-performance composite video cables available. Please click here to see them!
