Can you get XLR-to-RCA adaptors?

    ...and if so where? I assume this is accomplished by only connecting the positive line through (not the negative or ground), but is there a good way of doing this, without compromising the quality of the connection?

    Which end of the connection is the XLR (balanced) connection.

    If you want to keep optimum connection throughout ... try getting either balanced line recievers (pre-amp has balanced line outs but power amp only has un-balanced ins) or balanced line drivers (other way round).

    As for where to get these, or passive connector converters ... try Canford - they are a supplier to the pro sound industry but will supply to individuals with credit card (well they used to anyway)

    Hi Dan,

    No.

    XLR balanced is + - and ground, RCA unbalanced is + and ground.

    If you are talking about analogue connections (eg not SPDIF or AESEBU):

    To convert from Bal to/from unBal, you need a balancing transformer, or as sounddog has said, the active equivalent.

    Or you can hard wire (or get a hard wired adaptor),

    XLR + to RCA +
    XLR - and ground to RCA ground

    and this will work in many cases, but you lose the advantages of the balanced connection (eg hum rejection and so on) - this may not be a big deal if the signal level is high (eg line level) and the cable run is short, YMMV.

    NB some balanced devices might complain about having their - line tied to ground.

    Another supplier is StudioSpares in London,
    http://www.studiospares.com/viewproducts.asp?cid=3437&ctitle=ADAPTORS - XLR&p=1&gid=5

    their (hard wired) adaptors are £6.59 GBP.

    If you are talking about SPDIF / AESEBU conversion, (75 ohm unbal to 110 ohm bal) then an adaptor with built-in pulse transformer is what you need. Canare make these, as do Neutrik. Again Canford or Studiospares can supply these.

    best regards,

    Paul.
