What types of sync does the Extron Crosspoint or Extron Crosspoint Ultra take for RGB/BNC connections (I'm looking at the 128 12x8 models with HVC audio)? I've read everywhere it needs "pure" or "clean" sync which is the same thing as composite sync and csync, right? My NTSC RGBNES (toaster w/ SNES/Gamecube style multi-out), NTSC 'phat' SNES, and NTSC Sega Genesis Version 1 all use retro_console_accessories csync cables. I know my PS1 is sync on Luma and will need a sync stripper.
BUT, two different friends I PM'd told me that select systems which were using csync cables STILL needed a sync stripper for some reason? Just trying to figure out what I'm going to need to get an Extron to work (and if an Extron will even work for me).
I'm also planning on using the same Extron Crosspoint for some component connections too - which I'm assuming don't have any limitations like the above.
I have an Extron Crosspoint Ultra 450 series, imported from the States down to Australia, and I can confirm that they do indeed require CSYNC. With anything that outputs CSYNC naturally, all you need are cables that do passthrough sync, as in they don't do anything to the signal coming from the console and they're usually labelled as CSYNC cables or whatever. For things that don't output CSYNC straight from the console, as in most PAL systems, you'll need cables with sync strippers in them. For example, I have a PAL SNES and an NTSC SNES-mini. The mini has cables that simply output the CSYNC straight from the RGB chip in the console, while the PAL unit requires a cable with a sync stripper attached so the Crosspoint will accept it like the fussy baby that it is.
From my setup I have:
PAL SNES: sync stripper
NTSC SNES-mini: passthrough
PS1: sync stripper
N64RGB: passthrough (wired for csync internally)
