blade Posted October 3, 2005 Share Posted October 3, 2005 I want to use the emulated line (XLR) out on my 100 watt Marshall, into my desk and then PC. I've tried 2 leads to no avail, they only work when I wiggle them on the end of the pins. I called Marshall who say the XLR is probably wired wrong? any ideas. Regards Ade..

Andrew C Posted October 3, 2005 Share Posted October 3, 2005 Not entirely sure, but the Americans had pinouts wrong in the past. Damned if I can remember what they used though... Pin3 hot? Anyone? Link to comment Share on other sites More sharing options...
paulears Posted October 3, 2005 Share Posted October 3, 2005 It is most likely the way it is wired. On a bal to unbalanced XLR-jack you short pin 3 to pin 1, leaving pin 2 as the hot, to the tip. Some leads and output sockets are wired to need pin 2 shorting to 1, leaving 2 as the hot. If the amp has internally done it for you as well as the lead using the same convention, all is well. If the amp uses the opposite wiring, then you get zilch output. Just swap pin 2 and 3 in the XLR. Link to comment Share on other sites More sharing options...

RonJon Posted October 14, 2005 Share Posted October 14, 2005 Just a short note, incase your still scratching your head, the americans have a habit of running pin three hot as pointed out earlier, so if the unbalancing lead you have made up doesn't work, try making one up with the connector to the amp wired pin three hot, with pins one and two shorted, might look odd, but normally works when all else fails and the gear is in working order.

Rob_Beech Posted October 14, 2005 Share Posted October 14, 2005 First of all, Hi to RonJon welcome to the group. Have a look at the what do you do posts etc and maybe tell us all a little about yourself in there. Secondly, I once made a special unit (there's probably a few available on the market which are far more complex) which enabled me to alter wiring of a XLR of jack connector using various pins. For example. The unit would have an XLR and jack input, and an XLR and jack output. the unit consisted of various holes in which small patch type cables could be inserted to join pins together in the normal order, or handily any other order.A unit like this (as I said I've never had the need for one recently and there's probably alot of devices out there which do it)could connect and XLR 1:1 2:2 3:3 or 1:1 2:3 3:2 or short pins 3:1 or 2:1 in the case of different wiring. This wasn't a unit I would use live, purely as a test unit to work out the best way to wire some of the weird and wonderful connections of unknown equipment, it came in handy, I'd note down the connections and then simply build a cable copying it. I tend to work with standard stuff now and have managed to drop a cab on top of this unit and smash it to bits. Something like this would be handy in this situation, simple to connect and can of course be used either way. I may be missing something completely here (probably am) but is there a unit that allows you to do this on the market at the moment?This thing cost nothing to make.
