UTC A-10 In a ??? - Old Mic Preamp???

Audio equipment novice but enthusiast.

I picked this up at a garage sale and I'm not sure what it is, or who made it.

I researched the transformer, Universal Transformer Co UTC Model A-10, online and everything led me to microphone preamp or leveler

I asked a friend and he thought it was either home made, or rigged up in a studio.

Can anyone send me to a good online site or help ID this piece.

Thanks in advance/help.

Wow. 3 female XLR's, 1 unbalanced male TS, 1 transformer. I'm just enough of a tech to know that I don't know how to make sense of it. If it was just 1 female XLR and 1 pot I might guess it was an attempt at a reamp box. But I really have no clue.

That UTC A10 would make a dandy passive DI, btw, but not wired up like that.

There don't appear to be any active electronics. So it must be a passive mic mixer of some sort. 2x1 or 3x1.

What I can say is that it is really old.

The UTC and those pots are well worth keeping for a project but the box looks like it was built for a specific purpose.

Those large diameter microphone connectors haven't been used since maybe the early to mid 1950s. I think they were made by Cannon. So yes, it is old. Maybe even as old as me! Notice also, they are wired Pin 3 hot. That used to be very common, at least in the US.

That form was not uncommon for project boxes.
