    • LEN VIT02 Video Isolation Transformer - Analogue - 4kV Breakdown

      LEN VIT02 Video Isolation Transformer - Analogue - 4kV Breakdown

      The LEN 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 LVIT02 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 LVIT02 has been developed...

      A typical High Definition Broadcast chain features potential interconnects that could result in ground loops and the introduction of induced noise. Even though SDI is more immune to extraneous noise and low frequency components (hum) problems can still exist. As with analog signals, once you have noise in the signal, it is extremely difficult and costly to remove. Jitter caused by induced noise effects can compound problems created by unstable signal sources, poor re-clocking systems, cable attenuation...

      Video Hum Eliminators

      Markertek's stocks a wide selection of video hum eliminators that are designed to remove interference created by long cable runs, 60 cycle power demands, grounding noise, and magnetic coupling. Normal voltage differences between system grounding points cause small AC power currents to flow through video cables and even a small voltage drop can cause a visible hum bar. The low and high-frequency response of most video hum eliminatorsmake them ideal for high-definition and projection systems. Make sure you are stocked with plenty video hum eliminators for your next event.
