ok, those audio adapter are good. No problems there.

The following is generally true, just fyi and for a point of reference: CSYNC is the purest form of sync. Some argue that there’s no noticeable difference between luma and csync, some argue that there is. But, if you’re not committed to one or the other, best just to go with csync.

However, PS2’s don’t natively output csync. http://retrorgb.com/csync.html (scroll down to the PS2 part). The csync cable above (and any PS2 csync cable) has a built in sync stripper (based on LM1881, I’m assuming, effectively strips everything off of the signal except for sync). Whether there’s any benefit of csync vs luma sync in this scenario is not clear to me. Hoping others with direct experience can chime in.

For further reading, below is a summary of how the cable achieves csync:
Side note 3: We have received a number of enquires stating that the Playstation cannot output CSYNC. This is correct, the Playstation cannot output CSYNC, however, our CSYNC version of this RGB SCART cable has a built in sync separator circuit inside the SCART plug which takes the “sync over composite video” from pin 6 of the Playstation’s AV socket output and then the Sync separator circuit extracts CSYNC signal and sends this to the output of the SCART plug and the composite video part of the signal is disregarded. Here is the path of the sync signal from the PS to the SCART cable using a sync cleaner. PS AV socket (pin 6) —> Sync over composite video (CSYNC + composite video) —> sync cleaner circuit (removes composite video) —> CSYNC only—> SCART (pin 20), BINGO CSYNC!
