Applications
Using the VB-1BB to clean up the picture
The Iso•Max VB-1BB is the perfect ‘trouble-solving partner’ for baseband video transmission problems. It isolates the source and destination and rids the system of 60 cycle hum bars and other unsightly artifacts that can affect the video quality.
Solving hum bar problems with CCTV
When interfacing a distant camera to a video system, hum in the form of 60 cycle hum bars will often find their way into the picture. The Iso•Max VB-1BB provides a plug & play solution that eliminates the problem-causing ground currents without affecting the video quality.
Distributing video in large facilities
Distributing video around a large facility can often lead to quality picture problems caused by fluctuating voltage references at various power drops. The Iso•Max VB-1BB eliminates hours of trouble shooting by isolating the local monitor from disruptive ground currents.
