This done in the boxes like a video store and forward. Does it need positive or negative sync video input?

In the case of the VOL modulator, I am assuming it needs to have the video input already as 405 line format again would this be positive or negative sync video input?
Hi Adrian
You have the right idea on how the converters work. They all need a composite 625 line input 1Vpp. The syncs will be negative.


Vol is a standalone 13 Channel Band I/III System A modulator. It needs a 405 line composite 1Vpp input. Again the syncs are negative. Unlike Hedghog Hedghog II can be used as a modulator only.
