| Nady Mixer, any info? - Click HERE for Original Thread |

Hi folks
Whilst sorting out a load of junk in a house that I am helping rebuild, I found a Nady MXE-612 mixer. However, it has no PSU. Before I take it apart, (loads and loads of screws, bolts, pot nuts etc), I was just wondering if anyone knew the required psu and pinout? It would be a nice little project to rebuild and upgrade, as the psu is usually the weak link in budget mixers like this.
Thanks |

Hey, that is tiny. You are lucky you are not trying to open a big Peavey Unity series mixer.
You ought to be able to expose the back without pulling the knobs. These inevitably run on AC, and it is simple recto and filter circuitry feeding a three leg regulator or two. The rails will be +/-12 or 15v, so figure AC based on that.
I haven't been in one of those, but it looks like a three pin connector, so it is either am AC winding with center tap, or it is a winding and a ground pin. SHould eb able to determine that readily.
You might just call Nady for the schematic. They may even divulge the spec on the wall wart. And in the grand scheme of things, by the time al the energy and time is spent on making a power source for it, it might have ben more efficient to just buy a new one ready to plug in. |

| Yeah, it's quite cute isn't it. I approached Nady for schematics, and no joy, they insisted that even the psu voltage was proprietary information. I suspect it is just a boxed traffo, probably as you say to run 15-0-15 rails with a switched cap supply for the phantom power, and I have several of those around. The prospect of taking it apart doesn't worry me that much, after all, I have worked on 36/8/2 non frame desks before, I just wondered if anyone had the info to save me a little time. Oh well, looks like I will have to get the screwdrivers out! |
