Topic: Ucx ii clocking question

Hey colleagues,

I have an Ethernet interface which does not behave well under heavy load with low latency settings. Hence I decided to obtain RME ucx for its drivers and keep the preamps from other interface connected via adat.

What’s bugging me is the clocking thing. Let’s say I would like to have ucx to be clocked externally. That is possible but I will also use AES out of RME to feed my speakers. Does the RME in this case pass the clock thru towards AES?

Apologies if my understanding of this is incorrect. I could not find out this information in the manual.

Thanks,
Thomas

My understanding from UCX II as clock slave is this:
1. SteadyClock FS highly efficient jitter suppression refreshes and cleans up any clock signal and
2. sends a jitter free clock signal out on any digital output (including WC).

So yes, it will pass through the clock signal to AES.
Additionally, SteadyClock FS will perform jitter suppression which is a good thing.
