Eclipse word clock termination

[dahjem]

I couldn't find any documentation for the Eclipse's termination process.  I assume a typical T and 75ohm termination cap?  Just wanted to make sure there isn't an internal term.   Thanks!!  And love the V4Beta!!

Assuming you are talking about WordClock …

Eclipse is shipped with W/C unterminated. There is an internal jumper (JP1101 on motherboard, just behind connector)  which can be used to add a 75 ohm terminator, but this is normally not installed.

Using an external terminator on a BNC-T is the best way to do it as it saves opening the box and is also  immediately visible.

Strange that the User Manual is mute on this topic !

sorry to resurrect this prehistoric thread but as my BNC T connector just broke, can I place the BNC terminator on the WC OUT instead ?

What is your full setup / configuration of devices? You may not need to use a T piece or terminator.

Thanks for your reply.

It’s a bit complicated :

computer (MacBookPro) -> RME digiface usb set as master clock

Digiface ADAT1 & 2 In & OUT -> RME Fireface 800 as standalone device (terminated by switch),

Digiface ADAT3 IN & OUT -> RME Fireface 400 A as standalone device (terminated by switch)

Digiface ADAT 4 IN & OUT -> RME Fireface 400 B as standalone device  (non terminated) -> Eventide Eclipse + Word clock out of Fireface 400 B to Word clock in on the Eclipse + BNC T connector and 75 ohm terminator

Eclipse clock set on WC.

Hope that makes sense

I also previously tried to sync the Eclipse to the FF40 B using a S/PDIF connection (digital in set to RCA on the Eclipse and clock set to ext) but the clock signal seemed pretty erratic, always switching on / off

Anyway in the meantime I managed to find another BNC T connector and it seems totally stable now.

Do you think I am making a mistake in this setup ?

Thanks

Thanks for the info. If the clocking is stable with your current configuration, then there is nothing to worry about.

If there was a clocking issue in your setup, you would notice it quickly, so it sounds like you’re all set.

Thanks !
