when I use my Line 6 G50 with the power plus 2 I do not get audio out from the receiver. When I use the factory power adaptor for the line 6 it works normal. Any ideas. It seems strange. The power adaptor is 9v DC. Am I missing something here?

Does the pedal power have dip switches you need to set up?

What is the current draw of the G50? (and is it getting enough from the pedal power?

Its hard for me to advise, I dont have these 2 products but I will at least try!

I needed to use output 5 or 6 because of the high er current draw of the line 6. All works fine
