yorks5stringer Posted September 20, 2014 Share Posted September 20, 2014 Just come back from the sound check for tonight's gig in a Barn ( literally), it's a Wedding Venue. I do some throaty BV's and as my Mike lead was a bit short to the desk due to the size of the room, I joined 2 X 10m XLRs together... but no sound. So I disconnected them and tried each 10m one in turn and they both worked individually into the desk.Yet joined together they don't work. How can this be, it defies logic?

Huge Hands Posted September 21, 2014 Share Posted September 21, 2014 Did you get the same sort of level when trying them individually? It could be that one cable had been "ground lifted" - i.e. had the shield disconnected for noise or anti mouth zapping reasons, but the other one was either wired unbalanced or had an issue with one of the signal cores which would mean it would need the ground to complete the circuit ? You would expect the unbalanced or "one legged" cable to be quieter, but you might not notice so much in a noisy barn! Quote Link to comment Share on other sites More sharing options...
yorks5stringer Posted September 21, 2014 Author Share Posted September 21, 2014 No difference in sound levels! Quote Link to comment Share on other sites More sharing options...
rmorris Posted September 22, 2014 Share Posted September 22, 2014 well it would seem that the two cables aren't wired the same. Most likely to myself would be one cable having 'L' (pin 2) connected to 'GND/Screen' (pin1) an the other having 'R' (pin3) connected to pin1. Both of these cables could function between a balanced output and input but not when in series. Should be easy enough to undo XLR connectors and take a look or buzz out with a DMM.

flyfisher Posted September 22, 2014 Share Posted September 22, 2014 I keep one of these cable testers in my gig bag. Very handy, usually for proving to our guitarist that, yes, that crackling IS because he has a faulty lead! http://www.studiospares.com/test-gear/behringer-cable-tester-ct100/invt/370030?VBMST=Tester Quote Link to comment Share on other sites More sharing options...
yorks5stringer Posted September 22, 2014 Author Share Posted September 22, 2014 (edited) Checked all 4 XLR plugs and one of the the female ends had a detached earth wire which maybe could have been intermittently shorting onto a live one? Anyway now all sorted. Thanks Edited September 22, 2014 by yorks5stringer Quote Link to comment Share on other sites More sharing options...
