    Yes, the 5235 is unbalanced.

    Use the barrier strip connections, like Zilch suggests. Go from there to your single-enders and you will be fine.

    That is why I moved away from it.

    Balanced in, unbalanced out, non-standard pinnage. Plenty of explanation in the FM. Rob pointed out the URL ... 'nuf said? -grumpy

    Rob's idea, actually.

    Me, I'd still be scratchin' my head trying to figure out why the XLR cables didn't work....

    Me, I'd like to know how hard it would be to just flip the wires INSIDE the unit.

    Sort of head off the pinout problem before it me! I read the manual the other day, but already forgot about the pin 3 hot thing till I saw this thread!

    I recently went through all my mics to check polarity, the only one that I could not flip to current pin 2 hot standard was a SM-87, pins go right to a circuit board... Not into taking it further apart, so it sports a label "Negative Polarity".

    I just checked the users manual. Pin2 = hot. That is convention, and makes sense.

    I'm not sure what modified Shure you got, 4343!!

    A pain. The XLR's are soldered into the board. So unless you want to start cutting lands and adding jumpers stick to the terminal strip.

    XLR Adapter update

    Instead of making up custom cables as I had first considered, I found some inexpensive ($21.00 for six - delivered), 2 male and 4 female XLR to female RCA adaptors on Ebay. I spoke with the seller about the problem with needing pin #3 hot, and he assured me that it wouldn't be too much trouble to dismantle the unit and switch the two connections inside. Fortunately, I own one of the inexpensive Desoldering guns (Hakko 808) which should aid in the reconfiguration of these six adaptors. I'll keep you posted when the adapters arrive,to let you know if this is a worthwhile project or not. later, wpod

    Sorry, I typo-ed! Meant SM-81. Pin 3 hot on early models...

    Though I like the info, these kind of threads drive me nuts!
    I have several 5235 crossovers and I wired them following Rane's wiring practice chart. They all seem to work fine...but now I'm not comfortable knowng that I MAY HAVE wired them incorrectly at the JBL end!
    I'll have to pull out all the units, cables, and check polarity and referance them to the various factory wiring charts...!
    Wouldn't standardization be wonderful? !

    It's worse, Tom: jkc's Jensen Transformer link tells how to rework the outputs.

    Screw it. I'll use short cables....
