I just got a used Behringer UltraCurve 2496 and was trying to use the RTA. I can get it to play music using the Toslink Input and Output but cannot get it to emit any Pink Noise to do the Analysis. Any advice would be appreciated.
I had the same problem, but can't quite remember what I did to fix it. I think you have to go into the menu that is something like "connections" - the one that looks like a little block diagram/schematic - and connect the pink noise generator to the outputs.
