hello
I have the same problem but…
I have problem that during the show my board is stop playing any sound. I have select any channel and the gain reduction on compressor and limiter are fully red to the end and have no input signal. I have reboot the system and surface cannot link to IDR and i see the text “idr mix rack boot failure”. My mixer is now in polish service and i am waiting for the reason what happend.
