I purchased a new FM transmitter and was naive enough to believe that I could connect the audio from the 1/4th sound card jack to the XLR inputs on the transmitter, however the audio level is too low. When I try to turn up the volume on the PC, it overdrives the output and the sound card will shut down.
The transmitter I have has dip switches on the back for 600 ohms and 10k ohms. Just curious what the best way is to convert the audio?
I see these on ebay, but need the 600 ohm side to be XLR, so I'm not sure if this will work. Would a mixer do the trick?
I ended up having to run the computer audio into an input of a stereo receiver, then running the headphone audio out on the receiver into the transmitter; using the receiver's volume as gain control. I'm sure there's better ways to accomplish this.

Congrats... you've found an inexpensive and functional work-around, and if it sounds good it is. A more "pro" approach that might float your boat can be found by googling "level matching interfaces" which are capable of converting -10 sound card output to the +4 level your transmitter input expects. Cheap ones new can be found for around $60 usd.
Another option would be to peruse eBay and look for this type of interface by Aphex or Matchbox.

Thank you! I found the Aphex devices on ebay. Just want I need!
