Diver no sync thru switch

Hi I have a diver and I was trying to follow your vidiot + diver video and I noticed there was no sync switch. Is this normal?

Going forward, all LZX modules have fully buffered RCA sync and do not require a termination switch. If you are asking about an internal/external sync switch, Diver does not generate sync.

Thanks, I was just wondering if it was missing after I had watched the video
