Help C=... I am having problems with low video output levels on two Amiga 500s. It appears that what should be a little over 0.7 volts (100 IRE units) is instead more on the order of 0.5 volts (70 IRE), with the chroma levels down by a corresponding amount. This appears to be consistent with the observations published in one of the Amiga magazines a couple of months back. It seems the video levels out of different Amiga models can vary at least this much. The problem is that feeding these low video levels to the RGB inputs of a video projector or a DigiFeX(CMI) VI500 encoder result in dark, poor looking pictures. I would assume any other encoder or genlock that lacks video gain adjustments would have the same problem. Can someone at C= document what the situation is and ways to correct it? Alternatively, does anyone else know of a fairly cheap way to boost and adjust the three RGB signals up to standard.
