Connecting word clock

At the moment I have a Scope PCI system with a sync plate connected to my Akai S5000 sampler (with the internal termination switch on so I don't need a 75 Ohm terminator). Like this:
Code: Select all
Scope[sync plate]----------S5000[internal terminator on]
Now I want to buy a Lynx Hilo converter so I need to connect two device to my word clock output, will example 2 also work? I hope these examples are clear enough (T = T Connection like this one:
http://www.thomann.de/nl/pro_snake_bncw ... stueck.htm).
Code: Select all
Example 1)
Scope[sync plate]------T-----S5000[internal terminator on]
Hilo
Example 2)
[terminator]-T------------T---------S5000[internal terminator on]
| |
Hilo Scope[sync plate]
With example 2 I can use shorter cables hence my question.

Both example works - as long it's properly terminated

wordclock should not be connected serially.
there should be one clock signal sent to one device. for multiple devices, you need a distributor with multiple parallel outputs.

For now I will use the clock from the ADAT connection.
In the future I will upgrade my studio with an external wordclock (Apogee Big Ben). The Big Ben has 6 wordclock outputs, by then I need to connect 10 devices. How can I do that if I can only connect one device per output?
I'm a bit confused by the text below (from the Big Ben manual):
"Each Word Clock line should be terminated with a 75 ohm load, as indicated by Big Ben’s Termination
sensing LEDs. When the word clock input of connected devices is un-terminated, it’s acceptable to
chain a few devices with a BNC “T” connector on the word clock input."

as this is also being talked about in another thread
its ok to use t but better for point to point if you have the parallel ports but if you have 6 like on the big ben

I personally think of word clocks like MIDI. Not ideal to chain them, but really, it's better to have everything on word clock with a couple devices chained than not
(edit - jhulk's posted covered this better)

yes, that's correct.
in a home studio, it's probably not worth getting too worked up about, but there are clock distributors that only split a clock signal to 4-8 additional devices.

Here is an interesting blog post about setting up workclock:

I think I will buy a Drawmer D-Clock (Clock Measurement & Distribution unit). It has 20 BNC clock outputs so that should be enough.
