ULN2 Only one input active at a time?? [message #86372] Tue, 03 May 2016 18:05 Go to previous message

Somehow I've got my ULN2 in a state where it will only accept input from one channel at a time. I have tried with 1/4" and XLR cables. If I plug both cables in to a stereo synthesizer, only input 1 shows any activity. If I unplug the input 1 cable, input 2 starts working. I used to have it working with both simultaneously but obviously I messed something up somewhere along the line. No idea how I managed to do it! Any ideas on how I can revert it to the standard behavior?
