Question If I check the Input selection parameter in the Levels menu I see an option called "Digital In", but there is no digital I/O on the unit. Furthermore, if I select "Digital Input", the Nova System crashes. What is going on

These problems are caused by a wrong firmware version being used in the Nova System. Older (pre-summer 2011) Nova Systems had S/PDIF in/out ports, which is why it you can find "Digital In" in the Levels menu. Because we are no longer able to source the required parts for digital ins and outs on the Nova System, the S/PDIF option was removed from the new Nova Systems and a special firmware version is required, which basically just removes the "Digital Input" option in the Levels menu. If you need this firmware version, please get in touch with our Tech Support team.
