XLR adapter advice for BetaSP dub to DVD

    I am about to do dub some BetaSP tapes to DVD using a Sony BetaSP deck
    and a midrange consumer DVD recorder. The only problem is, the BetaSP
    deck only has XLR audio outputs, it doesn't even have a RCA line level
    "monitor out". I tried using a pair of XLR-to-1/4" and a pair of 1/4"-
    to-RCA adapters from Radio Shack, but the resulting audio had a
    distorted sound to it. I know the audio on these tapes and the XLR
    output on this beta deck are in good shape because it was connected to
    a sound board only a few months ago and produced great audio. So my
    question is this, what XLR-to-line-level-rca adapters/cables do I
    need? Can you recommend a specific model and/or online shop where I
    can purchase these? Thank you for the help.

    if all else fails - you can take a stereo feed from the headphone out -
    you'll just have to juggle the levels...

    i think you'll find that the outputs are 'balanced', so it could be that
    the leads you tried are 'unbalanced'. can't you ask the people supplying
    the vtr for the correct cables?

    A simple cable like this should do it if the deck has output level controls
    http://www.markertek.com/ProdList.asp?cat=CABLESCONN&subcat=AUDIOCAB&prodClass=ARCAXLR&search=0&off=
    Typically RCA audio inputs on consumer equipment is designed for a -10db
    signal
    XLR outputs on professional equipment usually puts out +4db. That is a 14dp
    diference.
    That is probably why it is distorting. If you can turn the level down it
    should work.
    If there are no output level controls you will have to reduce it by another
    means.

    Here are a few level shifters, but you could use an inline pad too.

    The 2800 has level controls for the inputs and the outputs,
    so you may want to try it again with the level turned down to -10db
    I've used the headphone jack as an unballanced output too. It works.

    There probably is an unballanced mono output on the monitor connector
    at the bottom of the back panel. Markertek and others sell break-out cables.

    I think you have to pull out the controls to make them variable.
    pushed in is a calibrated preset level

    The simplest way:

    Borrow a cheap Behringer or Mackie mixer.

    Feed the BetaCam via XLR into two inputs of the mixer. Adjust the clip/
    attenuators, and set a normal level just under 0db.

    Use the RCA outputs of the mixer to feed your DVD recorder.
