It lives! The PRE BMX III

I have just finished putting back together this PRE BMX III console.

We basically ripped the guts out of this unit and in doing so, I was reminded of how well these things are built.  The PRE BMX series consoles were truly wonders of audio engineering.  It is a testament to their ruggedness and serviceability that so many of these units are still in use twenty to thirty years after they were manufactured.

This console suffered some pretty bad water damage to the backplane:

Which was replace, along with many switches and buttons.  The Mic2, Mic3 and CD1 modules seemed to have taken most of the damage, there were several logic ICs and IC sockets that needed to be replaced on those modules.  Of course, this was not inexpensive; the parts were somewhere north of $3K plus about 40 man hours of labor… that adds up fast.

The good news, I think that the studio was back in service last night.

    You can still get backplanes for those PR&E mixers? Wow…

    I picked up a watered Ward-Beck a few years ago that was scrapped by WCBM (back when it was a Metromedia property). I knew it would never work again as a console, but I harvested enough intact electronic and metal parts from it to keep my junk box full and my project bench busy for years to come.

    The more “techie”-looking parts (meters, large-can caps etc) I gave to a sculptor to build into some wacky crap.

  • Paul, did you water-proof it this time?

    @Alan, Mooretronix has almost everything for these consoles. The backplane we received from them looked like it was salvaged from something else, but it did the trick.
    @Mark, We contemplated laquering the back plane boards, but put a rubber membrane in the ceiling above the console instead.

    Does anyone have a technical manual in .pdf for a BMX III? I’m doing a tiny bit of installation stuff on a system that uses one of them as their main on air console and I need the manual to plan my piece of that.

    Thanks very much!
