I just picked up a Universal Audio 4-710-D.
I have it connected to my UR816c from the ADAT out on the Universal Audio to the ADAT in on the UR816c.
In the control panel for the Steinberg Driver, it is set to INTERNAL for clock source and 44.1khz.
The Universal Audio is set at 44.1.
The manual for the UR816c says to do all this AND use a separate wordclock connector cable from the out of the UR816 to the wordclock in of the external device (the universal audio).
I am getting occasional and quiet clicks when I plug something into the channels going into ADAT into the UR816, but plugging something into one of the analog ins of the UR816 does not give me the same clicks. This suggests something with either the new Universal Audio unit or the timing.
Note: the “lock” light on the UR816 glows continually orange, and the lock light on the UA4-710 glows continually green.
I have tried the same thing at a different sample rate (48khz) and it was actually worse.
I tried setting the clock source to “external” in Cubase and it was actually somewhat better - even though I think this is wrong.
Does this mean I need the wordclock cable? Won’t the timing between the two be locked via ADAT?
Or is it more likely I have discovered that one unit or the other is faulty?
