So I’m using a Qu-PAC with an AR84 and they’ve been working perfectly for about 6 months without a problem with gigs 2/3/4 times a week.
However setup in a venue the other day and the AR84 just doesn’t want to play ball?! It powers up fine and the sync light is flashing orange/yellow as normal but the ready light doesn’t light up!
Also not getting any audio pass through either way and on the Qu-PAC it shows the expander as not connected.
I’ve tried power cycling and different ethercon cables etc.
Any help would be great fully appreciated.
Check the S Link connections that the pin wires are not bent or out the track
that keeps them in line.
Maybe try a firmware reload.
