I am getting a new Minimoog Voyager at the end of the month and I remember reading somewhere that it could hurt your Voyager by running the headphone output into the audio in input.
Anybody know if this is true? I don’t want to do anything to harm the synth but I know it adds a rough overdriven sound to it and I’d really like to take advantage of that without losing the stereo outputs.
Can somebody help me? I don’t want to screw up my new synth!! Thanks!!
I think it will be fine. There is at least one person who has posted about doing exactly this to preserve his stereo signal. In any case, it can’t be worse than using an ordinary output in the feedback loop.
Idea 
Use a stereo Y-splitter to utilise the various filter modes and spacing controls 
(a la “Kicking it up a notch”. (G. AE)
Yeah I wasn’t sure.
I asked the Moog technicians and they told me that nobody ever asked that before so they weren’t sure. So I might stay away from doing it since I’m not 100% sure it’s safe for my synth. They did say to run a BALANCED cable becuase the headphone out has a ground but they weren’t sure if I could ruin anything or not by doing it.
Beats me 
i suspect putting a mono cable in the headphone output and shortcircuiting it with earlier revisions of the voyager (such as mine) can lead to dmg of an ic and cause the problem described here

think a resistor was added to prevent this from happening again see thread
using a stereo/balanced cable shouldnt give you any problems
