Hey guys,
So in my building we have a Sony PTZ camera that goes into and Extron A/V Distribution amp (this guy) then from there it is distributed around the building to different locations using COAX cable (Lobby, offices, backstage etc...)
However recently our signal to the Lobby TV went haywire (Flickering image, sometimes none at all, lots of distortion). So we went to look at our DA and looked at the BNC connector on the cable that ran to the Lobby tv and as it was kinda loose we decided to replace it. It fixed it monetarily but every now and again it goes back to the same issue. But now all of the outputs are doing it. TV's in our offices have the same flickering distorted issues. (It almost looks like the lines you would see when fast forwarding or rewinding a VHS tape)
I've messed with the gain and EQ and neither of those helped (Which by the way an explanation of what exactly EQ does in terms of video would be nice)
There's a 75 ohm and High Z switch which it seems to only want to push signal to the monitors when its switch to High Z (again an explanation of what this switch is doing would be great!)
Most the monitors were working before I went up there and touched the DA (minus the lobby) so what has caused all of them to start spazzing out now? Is my DA bad (why did it go bad a soon as I touched it?) or is there another issue at play?
I've got a few very large events coming up here in August so I want to get this fixed before then but I also don't want to go out and get a new DA if that's not what is causing these issues.
Any insight is appreciated!
