Is there a limit to the voltage for the RGB lines going into AV1 of the ossc? (Scart connection)
I have a consolized MVS and I know you will want the CSYNC voltage down to 0.3-0.6V from the usual 3-5V you might get without a 470 Ohm resistor on sync line with 75 Ohm termination to not fry the OSSC over time, but is there a safe range for the RGB lines?
I’ve been trying to fine tune the Color bar test so that the RGB bars don’t bleed out as far on the last 3 bars. I’m going to rig up some pots or some resistors to sort it out, but was unsure what voltage can/should be sent to the AV1/Scart input.
Some say you need anywhere from 150-250 Ohms, to get it right with some 220uf caps as well.
I’m no expert, so perhaps wait for someone to validate this, but I believe the voltages for both RGB and sync are 1Vp-p, -0.3V to +0.7V, which goes for AV2 as well, and I think the video lines on AV3 (sync on AV3 still needs to be TTL/5Vp-p).
