Now the reason I ask this (please answer truthfully) is that I visited a music shop today. The shop in question sells quite a bit of pro equipment, among that Pro Tools HD systems. And the person I met had never seen a terminated word-clock. They did not have any T-couplings and no terminations in store. Maybe it was only that single person, but I'm in doubt.
Anyway, if you do not know what I mean. Wordclock should run on 75 Ohm coaxial cables, with BNC connectors. At the last receiver you should really put a 75 Ohm resistor, generally inside a special terminator plug. A few audio interfaces has a built-in switchable termination, very few though.
Anyway, do you terminate?

Seems like a valid question to me (I did pose it did I not).
Just found a thread about word-clock a few forums up. The advice was to connect:
in on box -- through box -- out of box -- cable -- in on next box.
No terminations, no T-connectors. Going through a box that destroys the signal.
I mean, yes, this is the way to chain midi signals. Not so Word-clock.
(Sorry, getting late, sounding a bit ... well, not meant that way anyway. One of the few things I actually know anything about).

Nobody said anything about it not being a vaild question? WC was always meant to be chained just as as MIDI, but just like MIDI, what has been learned is that using a house clock with multi outputs and distributing WC out to each device without chaining, or chaining no more than once, provides less latency and/or jitter resulting in a better quality sound with less artifacts.
Yes, you SHOULD terminate at the end of the chain. Like you sai
Yes, you SHOULD terminate at the end of the chain. Like you said, many devices have built in termination that can be switchable or is auto terminated. A lot of times you can get away without it. It depends on several variables as to if you really need to or not.
