Adding xlr or trs to Ureis, how?

    Hello one and all.

    Does anyone have any recommendations for adding xlr or TRS connectors to gear that has only barrier strips? I don't think I can go adding jack plates so the "pony tail" method is probably for me.
    Since these boxes will probably be used as insert devices, I guess TRS is the way to go (or not?).
    How are the pins connected?....i.e.: + goes to what, - to what, com to what......you get the idea.

    Thanks much,

    I have seen it done where a (reinforcing?) XLR jack plate is screwed on to the chassis, right where the strip used to be.

    Basic wiring for XLR would be G>pin1, +>pin2, ->pin3. (We won't get into pin2/3 debate here. For your specific purposes it is probably irrelevant. But you can try it both ways and see if there's a difference.) For balanced TRS it would be G>sleeve, ->ring, +>tip. For unbalanced TRS in a send/receive configuration, you'll have to look at your mix desk manual to determine which point is which.

    Hope that helps.

    Yes, Thanks. Though, if it's not to big a can o'worms....what is the pin 2/3 debate (in a nutshell if possible)?

    Either way, thanks again,

    It's not a debate! Pin 2 is hot. ;)

    But in Bizarro World, where Otari's assemblers come from, it's pin 3 hot. I need crib notes to wire things up 'cause of this.

    Hey Bear,

    Thanks for your helpful reply also, I have nothing with Otari written on it, so I guess I'm livin' in a 2-pin hot world.

    Weird thing is, your post wasn't here when I was writing my thank-you post.......huh...

    That one ain't so weird, only 3 minutes between posts. I've sometimes started a post, walked away in the middle of it, and came back to finish it over an hour later. It's really embarrasing when you have 3 or 4 posts hit before yours that make yours entirely redundant or irrelevant. haha
    Good thing we got an edit button, eh?

    Not just Otari gear. My Tascam MS-16 from the 80's is pin 3 hot as well. Pin 2 hot has become much more of a standard in the last 10 years. Check your manuals to be sure.

    Yup, there will be the odd pin3hot piece here and there. In most cases, it will not affect the operation or sound output in a substantial or detrimental way. It's 6 of one, or a dozen minus 6 of the other. In other words, (with a few exceptions) the wave you put into the machine should be the same wave you get out of it, regardless of which way it's flipped inside the box.

    One notable exception being tape machines. Having the polarity reversed on tape would make a difference if you transported that tape to a machine that had the correct polarity.

    Ampex=Pin 3 hot, Otari=Pin 3 hot
