The part you’re missing about those three “switching” supplies is that all of them are hybrid designs: the Doepfer PSU-3, Malekko Power, and Zeus Studio Bus all have bulk DC-DC switchmode converters followed by linear regulators.
Even really great switchmode designs for music modulars like Intellijel supplies produce too much high frequency hash for video work (personal experience). You’re not in Kansas anymore.
The exceptions, of course, are LZX modules that have their own regulation onboard–but those can take bulk +12V from a barrel connector too.
But Kansas was fully Monorocket for years in LZX-land at the onset from about 2011-15. The earliest Visionary systems run by LZX were in that beautiful yellow Monorocket case. My understanding from Steve at Livewire (nee Monorocket) is that several of their cases power supplies were designed and implemented with Video needs particularly considered. Not saying all Monorockets fall into this category, and the cases they made for Pittsburgh Modular performed particularly poorly for video in my personal experience…but I know a lot of folks whose output was, and still is, via Monorocket offerings for the video world.
TLDR: not all Monorocket power supplies are equal.
I can’t wait for the next generation of LZX modules where super-clean power from the case won’t be as big of a concern (and hopefully won’t be a concern at all)!
I took a 12U portable mixer rack, threw eurorails on it, and tossed two Doepfer PSU3s in. There is room for days behind even the deepest modules. It was an incredibly easy build.
It does indeed, but it’s actually pretty easy to do. It’s all very well documented. So as long as you follow the instructions, and makes sure there’s no exposed wiring, it’s pretty foolproof.
