Chris B Posted February 2, 2012 Author Share Posted February 2, 2012 So after speaking with EDM via email, which has excellent technical support the problem turned out to be lack of a line level attenuator. My wife went and purchased what edm recommended to me from radio shack and after a brief explanation to her via phone while i was at work tested it out for me. After adding the line level I can transmit for blocks, as tested by her mother driving away from our house and letting us know when the signal dropped out. Very ggod company to deal with, would use them again! Chris 1 Link to comment Share on other sites More sharing options...

And once installed did you adjust the volume coming out of the computer?My EDS was at full power (in the garage) and while the signal worked well out front, it was very poor/non existent in the house. (1 maybe 2 walls away) 1 Link to comment Share on other sites More sharing options...
Chris B Posted February 2, 2012 Author Share Posted February 2, 2012 http://www.radioshack.com/product/index.jsp?productId=2102975Actually tested wih an mp3 player instead of the computer. Again so far so good. Chris 1 Link to comment Share on other sites More sharing options...
Chris B Posted February 2, 2012 Author Share Posted February 2, 2012 Often people end up driving too high level audio into the EDM units. This causesterrible distortion on the receive side making users to think that they receiveda faulty unit.Please remember that the EDM units require consumer level -10dBv line-levelaudio. The output from a MP3 player or PC sound card may be much too high forthe EDM.Simple rule of thumb: If your audio source is strong enough to power a set ofheadphones or earphones, the chances are very good that you will end up withdistortion on the receiver side.The simplest solution is to add a inline volume control to bring the range lowenough for the EDM units to handle.

Thanks for posting. I ran my EDM from the earphone jack on my PC and didn't experience any distortion unless I had the volume maxed out. However, I may go one of the Radio Shack controls you posted and see if I can tell any difference. Again, thanks for posting. Link to comment Share on other sites More sharing options...
Chris B Posted February 2, 2012 Author Share Posted February 2, 2012 Actually it wasn't a distortion problem, it was a distance problem. I would only get 5 feet out of the thing. Apparently my computer was overdrviving the inputs basically killing the output. Yes I tried lowering the volume of my computer but it still didnt help. And yes it was an email response from edm, one of many. Link to comment Share on other sites More sharing options...

Max-Paul Posted February 2, 2012 Share Posted February 2, 2012 thanks Chris for dropping back in to let us know how it worked out. Interesting how it sounded good in your house but not out in the car. And it was all because you where over deviating. Link to comment Share on other sites More sharing options...

(referring to the other meaning of F.M.) As seen in this tread. Link to comment Share on other sites More sharing options...
Guest guest Posted February 4, 2012 Share Posted February 4, 2012 Well, the guy who was credited as the "inventor" of FM jumped out of his 13th floor NYC apartment window....so you may be right...:shock: Link to comment Share on other sites More sharing options...
