The LEN VIT02 Video Isolation Transformer acts as BOTH a Hum Eliminator AND a Ground Isolator whilst also improving on the performance of the traditional individual products.
The VIT02 will remove severe interference caused by 50 or 60 Hz hum whilst a normal "Humbucker" will only remove moderate interference.
At the same time it acts as a high performance Ground Isolator eliminating ground potential differences between equipment with a minimal phase and gain distortion. The VIT02 has been developed to withstand the high breakdown voltages required of medical applications.
