Hy maybe some one can Help me.
I did that mistake that I connect an input on the back of my voyager with another Input on the back of my voyager.
Can this maybe damaged something?
I’m new on Analog Gear and so I have fear that I damaged something.
Please Help.
(sorry for my Bad English)
No harm should have occurred. An out to an out might cause some damage, though. 
Welcome Arnie.
No harm done. Input to input will simply do…nothing.
Output to output is not recommended. Although if connected temporarily for a short time by mistake, it shouldn’t do any damage either.
Thanks for the fast answers. Im happy to hear that I don’t damage anything.
