D-premiers (dual mono) rca to xlr does not work on companion

[ogs]

Does both of them work as a standalone stereo amps? Maybe the digital out on the master does not work? Try swapping them. @devianet  is maybe on to something with gen1 vs gen3

Hi.
I'm very grateful for this suggestion as it works.

I have swapped them round master with companion and it started first time rca to rca-xlr (adapter) 

So in my case setting up the newer 2012 model as master doesn't work but swapping them round to the older 2011 as master all work first time with exactly same SD cards setup.

Thanks again.

That is brilliant! Looking forward to reading your impressions later in the week
