I'm hoping someone can help. I have a Pioneer 737 with a cinematrix mod connected to my Electrohome ECP3500 via a 5 BNC to 5 BNC RGBHV cable. The problem is that the voltage of the V sync seams to be too low for my ECP to pickup. I know Keene do a syncbooster but it's scart in and out. Does anyone know of a sync booster that uses BNC connectors? Thanks, Stuart.
