ShubiSnax Posted March 10, 2017 Report Share Posted March 10, 2017 Hey guys and gals, Bit of a noob question, but I'm having some trouble figuring out how to wire my cable. I want to run a Lectro R1a as a wireless reference track to camera(Arri Amira) I need to wire a 3.5mm trs to XLR. I'm concerned that the R1a will output a dual mono signal because it thinks stereo headphones are plugged in. I just want a balanced mono signal from R1a to single XLR input on camera. Is this possible? Thanks for your input and or output Quote Link to comment Share on other sites More sharing options...
Derek H Posted March 10, 2017 Report Share Posted March 10, 2017 The R1a output is not balanced so no it's not possible to have a balanced connection. You can still feed unbalanced signal into the Arri's line inputs. Your choice if you want to send the signal to one or both inputs of the Amira. I say go to just one, it's easier to construct and putting the same sound on two channels doesn't really buy you anything. Let the editor click the center pan button I say. Check with Lectrosonics for the correct wiring config but I would suspect it's something like Tip-pin 2, ring-sleeve(ground), Sleeve-Pins1+3 Quote Link to comment Share on other sites More sharing options...

Derek H Posted March 10, 2017 Report Share Posted March 10, 2017 It's possible the 'correct' way to wire the XLR is to leave pin 3 floating. Depends on the balancing scheme of the Amira input. Transformer vs active balanced. I don't know which one it is. Quote Link to comment Share on other sites More sharing options...
