    :lease: does anyone know which is the polarity of the XLR pins of the AV192R XLR outputs option?

    I'm going to purchase the cables to connect the preampl with a Theta Digital Dreadnaught and I would like to do not miss it up...

    The Theta has the following polarity : pin-2 positive; pin-3 nevative for Non-inverting Output, does a ordinary european XLR cable fit the job or should I ask for a special cable because the Theta has, like other american power ampl the polarity inverted?

    Thank a lot for your help

    For all the folks who are learning...Problem sorted out: Pin 1 = neutral; Pin 2 = Positive; Pin3 = Negative.

    Actually there is no danger of any short circuit at all: the only proble is that the signal, if the polarities would have been inverted, would have been in phase opposition.

    Does anyone have a comment on going from RCA to XLR?
    I have a set of TAG RCA to RCA cables and have just bought the 2540x3 amp which takes an XLR input.
    Trouble is my AV32 only has RCA out and I want to try the XLR in on the amp - any suggestions?

    Can the RCA to RCA be converted at one end to male XLR's?
    :lease:

    Short answer - yes.

    I used to have XLR on my 250 x 3 amp going into the RCA connections on my AV32SP/DP.

    TAG also had a service to change RCA to XLRs on their interconnects, if required. I don't know if IAG can do this, though.

    For the full run down on balanced vs unbalanced and a few permutations in-between check out Doug Selfs website at :
    http://www.dself.dsl.pipex.com/ampins/balanced/balanced.htm

    TAG published a piece on their website that was a spin-off from this original article.

    There is a pinout as well of the cable you are after. For those who don't know, Doug was the designer of the 250x3R.

    PS. For those into bizarre retro technology his website is an amusing read ( http://www.dself.dsl.pipex.com/ ). He's strangely obsessed with vehicles that seem inherently unstable due to insufficient wheels! The gyroscopic 2-wheeled train is one of my favs :eek:)

    Caleb,

    In the 250MRx3 manual, there is a schematic of an RCA to XLR connector (appendix p.29).The important point they stress is not to connect the screen pin 1 to the metal body of the XLR plug. I converted all my RCA to RCA cables to XLR (F) to XLR (M) 250MR input; works well.

    Thanks to those who replied.
    I have ordered thrtee XLR male connectors and will do the conversion using the schematic in the manual.
    Regards
    Caleb :thumbsup:
