I bought a slim phatty some days ago, and tonight had a problem i don’t understand. I came to shutdown my stuff, my slim phatty being mounted in a rack with a future retro xs on top. When i put my hand on a metallic part of the rack, i get an electric shock. So i did some tests to check where it is coming from and i noticed:
If only the slim phatty is turned ON, and the jack output is connected to my audio interface, no problem.
If only the slim phatty is turned ON, and the jack output isn’t connect on it, bad things happen when i touch my rack.
this is the sort of issue where I’d recommend contacting Moog tech support directly before looking for feedback fro the forum… first thing I’d suggest is you may have a bad electrical outlet or power cord, that is not supplying proper ground. Try using a known-good IEC power cable from another piece of gear, and try plugging into a different outlet or surge protector… if you have a tool to check ground continuity in your outlets you might use that to test your setup as well.
If that doesn’t sort it out, you should get an authorized technician to make sure all the ground connections inside the SP are correct. Contact techsupport@moogmusic dot com for further assistance.
I sorted it out, calling my distributor here in france. In fact the problem was coming from my iMac, it wasn’t connected to the ground. So when taking in my hand a jack connected to the audio interface and touching the rack, SHOCK ! after connecting the iMac to the ground, no more problem …
He tried to explain why it was happening, but didn’t really understand, something to do with a ground loop. But after that another problem when grounded, i got digital noise in my monitorings. But with the macbook pro nothing, everything is ok. I was about to ditch my audio interface thinking it was the faulty, but no, my iMac is acting weird sending garbage through the firewire cable.
