Can someone explain this for me? I’ve never really understood it. Why do you have to do it? What is it that you’re supposed to do and do I need to bother.
I’ve been clocking my Apollo with the Burl DA (the revolution would stand in for the Burl if that’s what I decide.) Then I go spdif to aes to the Trinnov and have been clocking the Trinnov via the spdif to aes cable. Do I need to clock everything via wordclock? Do I even need to worry about termination?

I’m going to over simplify this but a word clock terminator is like an electronic dead end sign. It’s a really cheap device a BNC plug with a 75 ohm resistor across the 2 terminals. Just put one on the WC output of the last device in the chain.

my understanding is that the S/PDIF or AES connections have "internal termination" (but may require setting it on/off digitally in some app specific to your devices?). I've only used a physical terminator when using 75 ohm coax cables with BNC connectors on the back of devices. That was so long ago I can't even remember what those devices/interfaces were now... maybe an old Digi 002R?

I am certainly not a wordclock expert, but I've always preferred to clock with wordclock connections instead of digital audio connections. It's just always seemed more reliable. For termination, I've always done it on the input of the wordclock using T connectors - with a terminator on one side of the T. I use a master clock because I have a bunch of devices. The master clock has a led indicator for each connection to verify they are properly terminated. Some of my devices have built in termination (Lynx Aurora).
