DeafDave Posted February 20, 2014 Report Share Posted February 20, 2014 Its just wired as a balanced cable, no electronics added. Its mass produced so its not something you can open easily but you can use a multimeter to test continuity and know how its wired inside.

Eric Toline Posted February 20, 2014 Report Share Posted February 20, 2014 A balanced XLR to a 3.5mm TRS connector is wired XLR pin one to the TRS sleeve, pin two to the tip and pin three to the ring. OTOH all Sennheiser G2/3 are unbalanced in & out and that's how the Sennheiser supplied molded output cable is wired, shield/ground to pins 1 & 3 and pin two to the tip. They are prone to failure and cannot be repaired. For a line level input to the tx an unbalanced cable with XLR pin two connected to the ring is required.

Rick Reineke Posted February 20, 2014 Report Share Posted February 20, 2014 As our esteemed friend Eric stated, both the G2/3 EK100 receivers are unbalanced. The included (POS) Sennheiser 3.5mm to XLR output cable is wired correctly for use with a balanced mic or line XLR input however I made replacements with Canare L2E5 mini, TecNec locking plugs and Neutrik XLRs. Po' pitiful me, I don't have either a 664 or 633. G2/3s work OK with my 302/744 set-up but in some instances additional line level gain would be nice .. so I'll use mic level as well. I have also used them with a Tascam 680 which has acceptable gain in line mode. Go figure Quote Link to comment Share on other sites More sharing options...
John Blankenship Posted February 20, 2014 Report Share Posted February 20, 2014 A friend of mine had a quite similar issue with his G3s feeding a Nomad. Following the advice that I (and several others here) outlined earlier, his problem was completely solved and he's lived happily ever after. But, then, he didn't approach it with a chip on his shoulder. Quote Link to comment Share on other sites More sharing options...
al mcguire Posted February 20, 2014 Report Share Posted February 20, 2014 Call Dr Toline at Eldercables Ltd. and get a set of his hand built Artisan G3 cables. They come with a Lifetime warranty which unfortunately is Erics lifetime. All your problems soon be gone Quote Link to comment Share on other sites More sharing options...
rich Posted February 20, 2014 Report Share Posted February 20, 2014 well, fair enough. i am surprised that it was the connecting pin 3 to pin 1 that was the cause of your problems. especially as it states in the 664 manual that for unbalanced connection you should connect pin 1 to pin 3. but there you go. you learn something new every day. even if you hadnt meant to.

gamaufvisuals Posted March 20, 2016 Report Share Posted March 20, 2016 Awesome post. It works also with my Wendt X4 (mic-level output) and my Sennheiser G2´s. Thanks a lot! Quote Link to comment Share on other sites More sharing options...
