      Comments about Kramer 123VXL 1x3 Differential Video Line Amplifier:

      Great use as a signal amplifier from video split taps on film cameras.

      I have used it with ARRI 435's as well as 16mm and HD Genesis Cameras (through a downconverter) and it's a great little device to turn 1 signal into 3.

      The gain control is also a great help on older video taps which are quite noisy and low quality.

      The only drawback i have found (and this may be my own issue, still investigating) is that when running from generator power instead of mains, i get slight black noise in the image from the unstable power source. This should be rectified on the next job i do when i run my video split rig through a UPS.

      Great value for money though and incredibly small and lightweight.
