    Hey Folks,


    First off.... HAPPY NEW YEAR!

    Okay now my questions....

    I ordered a Behringer Ultra Tube-Q and it should be here
    on Jan 06.....

    It has Unballanced (1/4" Microphone) and Ballanced (XLR)
    Inputs and Outputs.

    Can an XLR Connector be used on one end of an RCA Patch
    Cord if the RCA Cable is of the "ballanced" design with a
    center Earth Ground that goes to the chasis of the component?

    I know that i can use a 1/4" Microphone Connector on the
    end of an unballanced RCA, Or I could remove the 1/4" Mic
    Inputs and Outputs and replace those with good gold RCA
    Female/Female feed thru's but I don't want to mutilate the
    case to do that..

    So can I do an XLR to RCA?

    Brett,

    First, there is no such thing as a “balanced” RCA connector.

    Second, when you combine balanced and unbalanced connections you end up with an unbalanced signal path. So, there is no reason to use XLR’s and RCA’s together.

    Just get some ¼” to RCA cables - it’s the simplest alternative and it will work fine.

    Wayne,

    Thanks for the reply..

    What do you call an RCA that has an Earth Ground stap
    incorperated? Isn't that all an XLR does, Cold, Hot and
    an Earth that grounds the chasis of 2 componets together?

    I will go wit the RCA to 1/4" I just wanted to see if it
    was feasible to do XLR to RCA (I like the XLR connector
    better, seems more heavy duty)

    Again many thanks!

    Brett,
    I just purchased some decent XLR-RCA cables from MCM at very good prices. They had some on clearence, but I don't know if they are still on sale. Like Wayne said, they are very easy to make though.

    Wayne,
    The RCA cables I am speaking of in particular can be found
    at Parts Express manufactured by Scroche and Pheonix Gold
    and they are listed as "Ballanced RCA Patch Cords".
    I am good with a soldering gun.. Radio Shack carries some
    Neutririx XLR Ends and I was just going to buy 2 pairs of
    thier new Fusion A/V Audio Cables (RCA) lop the ends off
    one side and solder on the XLR or the 1/4"
    I know the 1/4" will work for sure, and it's nice to know
    that the XLR can work too.
    I didn't think about the fact that Behringers products are
    all Pro Audio and I was assuming that it had RCA Outs and
    Ins.. Till I read the PDF Manual onliine... Dowt!
    The sad part is, had I know that I just would have ordered
    XLR to RCA's from Musicians Friend, that's where I ordered
    the Ultra Tube-Q from..

    Thanks Wayne and Jim!

    Wayne,
    Sorry I meant "Soldering Iron" [​IMG]
    I am not new to soldering, I have been restoring old Lionel
    Trains for years, and any other little projects that come
    along to play with solder and an iron.. All of my Speaker
    Cables are DIY and they are all 4% Silver Soldered connections
    and such.. I love soldering [​IMG]
    I do need to get a new tip for my iron though..
    Thanks you SO much for the "schematic" on what to connect
    to the XLR I was fairly certain I could run a jumper on
    those pins.
    I haven't decided yet which way to go though, the RCA
    Barrels you show above, PE also makes matching 1/4" Mono
    Plugs in the same color and style so I could go that way
    too.. I was searching RadioShacks web site and it doesn't
    look like they have any good 1/4" plugs, but they do have
    the nice XLR's and they do have the nice Fusion AV cables
    in stock (which even come with Ferrite chokes on the cables)
    I may just hit Rat Shack rather than place a tiny order to
    PE because right now I don't need anything else.
    Again MANY thanks!
