enjoyfebruary Posted July 2, 2015 Report Share Posted July 2, 2015 (edited) Hi guys, so I'm pretty new with wireless in general but i'm trying to troubleshoot a distortion issue that has cropped up in the last day or two with my OST 801 and UCR211/200c. Not sure if it is the mic or the wireless that is the issue. Take a listen to the file attached (sorry about the noisy environment, thin windows+busy street) and tell me what you think. Up until this last weekend this setup has been a champ. A clue I possibly found is that when I unscrew the TX antenna, the resulting audio obviously became worse, but it exaggerated the identified distortion. So maybe it's more related to the Lecto? Anyway, any input on what this may be would be very helpful. Thanks!

ProSound Posted July 2, 2015 Report Share Posted July 2, 2015 Via my macbook air speakers I am not really hearing any distortion. It sounds thin when your voice peaks but that isn't distortion Quote Link to comment Share on other sites More sharing options...

It sounds thin when your voice peaks but that isn't distortion Thanks for listening. It's subtle which is why you probably couldn't hear it on the Air speakers. Definitely noticeable in my headphones like kind of like a sandy, buzzing, snare drum type sound. Quote Link to comment Share on other sites More sharing options...
Dean Slotness Posted July 2, 2015 Report Share Posted July 2, 2015 Sounds like you are describing compandor noise. Try turning the transmitter gain up and the receiver output down, this will improve the signal to noise ratio and the compandor sound should be reduced.

I'll do a little research on Compandor noise and see if that is what is going on. Quote Link to comment Share on other sites More sharing options...
Miles Anderson Posted July 6, 2015 Report Share Posted July 6, 2015 on top of some of the possible aforementioned setup errors, the case could be that the mic is wired incorrectly. Quote Link to comment Share on other sites More sharing options...
TommLab Posted July 7, 2015 Report Share Posted July 7, 2015 On the tx side (UM200C) how much gain are you using? Quote Link to comment Share on other sites More sharing options...

I pulled the TA5F apart and it doesn't look like anything is shorted. Quote Link to comment Share on other sites More sharing options...

Yes. how is it wired? Should be wired like LMa I think. Do you even know how it is wired? Would you care to tell us how it is wired? Quote Link to comment Share on other sites More sharing options...
