VIT261 - video isolation transformer and hum eliminator

VIT 261 allows to eliminate the Ground Loop Interference and ground voltage difference from video signal. 

The main features are:

• Video passes through, hum is stopped
• Noise elimination and smooth video signal transmission
• Standard safety earthing of all apparatus
• Easy to use: simply insert at any point in effected transmission line
• Rugged construction and  small size

Now, thanks to the VIT 261 is possible to eliminate “hum bars” and other video disturbances caused by ground voltage differences (ground loops) or electromagnetic pickup in coax cable.
If the source (e.g., mixer) and the load (e.g., monitor) are grounded via different AC circuits, there are probable ground voltage differences, while if the coax cable runs parallel to AC power wiring you can have the electromagnetic pickup.
VIT 261 has a smooth response, negligible insertion loss, and have no differential gain or phase distortion.
VIT 261 is specially projected for use with standard 75 Ohm composite or component video signals.
