Guest bluecheez Posted August 24, 2012 Report Share Posted August 24, 2012 So I accidentally snapped my lavalier after rolling it over with my rolly-chair. I'm trying to fix it by soldering it together. I attached two pictures of it. There are two cables, separated by insulated plastic. I tried soldering them together without luck; my computer recognises that a microphone is plugged in, but no sound. There are some other "damages" in the wiring where the copper wire looks like its been tugged or warped. I think it could be 1 of 3 problems: 1. the soldering job I did wasn't good enough 2. the microphone head is dead 3. microphone head is working, but there are other damages in the wire that break the connection. Any ideas? I was thinking of cutting microphone head side and plugging it into an oscilloscope to see if the microphone head is still working.

Eric Toline Posted August 24, 2012 Report Share Posted August 24, 2012 First at the open splice point see if you have continuity between the ground and the sleeve of the input connector then between the white wire & the tip of the connector. Also at the splice point see if there's continuity between the ground & the white wire, if there is the you've got short in the cable somewhere. I would suggest cutting off the suspect cable about 3" below the capsule and splicing in a new cable & connector. BTW is that a Sennheiser ME2 lav?

soundslikejustin Posted August 24, 2012 Report Share Posted August 24, 2012 BTW is that a Sennheiser ME2 lav? Eric Yup. I would not be bothering... Quote Link to comment Share on other sites More sharing options...
Guest bluecheez Posted August 24, 2012 Report Share Posted August 24, 2012 Thanks a lot for your post Eric! I have a few questions for you: First at the open splice point see if you have continuity between the ground and the sleeve of the input connector then between the white wire & the tip of the connector. Which part is the ground? Is are you referring to one of the 3 parts of the male-aux-in input connector? Which part is the "sleeve of the input connector"? Also at the splice point see if there's continuity between the ground & the white wire, if there is the you've got short in the cable somewhere. I never thought of checking for a short that way. So we're testing to see if the insulated-inner-wire broke out of the insulation and is touching the other cord. I would suggest cutting off the suspect cable about 3" below the capsule and splicing in a new cable & connector. The capsule is the microphone head, right? My only concern with doing this is that unfortunately there is some suspect wire close to the capsule itself. BTW is that a Sennheiser ME2 lav? I'm not sure actually. It looks identical to the ones in the pictures I've looked up online, though. Why do you ask? Do they have a reputation for being delicate? Also I wonder if the connection from the microphone to the wire is loose or cut. Or that the microphone itself is broken. Thanks for the help!!

Vincent R. Posted August 24, 2012 Report Share Posted August 24, 2012 Yeah these sennys are not that great. Therefore Justin's comment I guess. I wonder about your testing procedure; you just plug it into your computer? Like what? In your sound card? Did this work before without any pre amp? Can't you test it with a G3 or G2 system where this lav probably came with? Quote Link to comment Share on other sites More sharing options...
Rick Reineke Posted August 24, 2012 Report Share Posted August 24, 2012 "I wonder about your testing procedure" Same here.. try it in the proper device. The ME2 and most lavs require 'bias current' (sometimes called, 'Plug-in Power'). And some PCs inputs don't supply power to their 1/8" input which may be line level. In addition, that kind of locking plug doesn't fully insert into an normal (unlocking) 1/8" jack. Quote Link to comment Share on other sites More sharing options...
studiomprd Posted August 24, 2012 Report Share Posted August 24, 2012 I believe Bluecheeze answered his own question: 1, 2, or 3. Quote Link to comment Share on other sites More sharing options...
