Topic: Synchronizing UFX with 2 adat and 1 AES/EBU

I want to know how is the best way to synchronize ufx with 2 adat octapre and 1 stereo preamplifier with aes/ebu ?
Thanks.

Re: Synchronizing UFX with 2 adat and 1 AES/EBU

Hi,
I assume you do not have the Octapre MKII Dynamic which is an AD/DA.
The Octapre is an AD converter only so you will need word clock.

The UFX should be set to Internal Clock and the Octapre and AES device should be slaved.

To clock the Octapre you will need 2 WC cables a T-connector and a terminator.
Both Octapre should be set to WC input as their clock source.

The Stereo Pre amp needs to be set to AES input as the clock source.


Thanks Chris

Re: Synchronizing UFX with 2 adat and 1 AES/EBU

First thanks for the explanation wink
Sorry i didn't explain well. I have an RMEufx and 2 RME octamic II Preamp and a Audient Mico preamp.
I didn't understand well some points

first : i put the T-connector on ufx and send each WC cable to eatch octamic? and you talk about a terminator... where i find one of this and where should i plug it?

second: i don't need to send WC to audient mico too? it synchonize just conecting the aes/ebu cable?
sorry for the poor english...

Re: Synchronizing UFX with 2 adat and 1 AES/EBU

please an answer...
I've made some tests and it seems to mee that audient mico ( conectec with AES/EBU) need to receive WC too to syncronyse it's correct? if it is how can i setup the all system? i will need 3 WC to send to 2 octamic and to audient mico... with a T-cable i only get 2 ...
And at last can you explain me better the terminator...

Hi

I use the UFX, Audient Mico to AES, Octamic D, ADI 8-DS
I get the best results with an external clock. I use a Mutec.
From the clock to every device and everything works fine.

Re: Synchronizing UFX with 2 adat and 1 AES/EBU

RE: Mouga:

Use a second "T" at the second Octamic - the output of that "T" then feeds the Audient with a third "T" - the 75 Ohm Terminator goes on the Audient's "T" connection to terminate the chain (or the Audient might have built-in selectable 75Ohm termination eliminating the third "T" and external terminator).  If the Octamics also have slectable termination - make sure they are disabled / un-terminated (don;t want to "double terminate" and end up loading your WC Chain with 37.5 Ohms)

Terminators and "T's" can be found at any Video Supply type seller (Markertek, BSW, etc).

The benefit of using the UFX as the system master is that your Software can then control the Samplerate of the entire system.  Using an external master clock like moties mentioned is also an option, but unnecessary in your application IMO (see here for real-world external clock testing results).  Once a system gets too large, an external clock is generally required - but I've gladly ran 4-6 devices in a "T Loop" w/o any issues what-so-ever (assuming you can get the termination sorted correctly)...
