Features & Specifications
The AudiaX DGT-301 FM Transmitter operates on a frequency range of 88.1 MHz to 107.9 MHz and gets its power from a single AAA battery or an included DC car adapter. The LCD simply shows battery life remaining and the channel the device is broadcasting on. Power output is 250uV/m and the output range is 10m. Running on an AAA battery the device can run for 18 hours.

Setup & Use
To use the device all you do is plug its headphone adapter into the port on your MP3 player. The transmitter will search out the best station for your area automatically and you can then set your car radio to the same frequency.

I found that the device didn’t always find the best station for my area automatically. In fact it twice chose frequencies with clear broadcasts in my local area. Despite that one of the channels it chose automatically worked very well for broadcasts.

I found the audio quality with a generic MP3 player (it won’t work with my iPhone) to be good, though volume was low compared to normal radio stations. I did find that the AudiaX DGT-301 FM Transmitter is very sensitive to where it is in regards to the radio. If I moved the transmitter literally an inch further from the radio interference was introduced. With proper positioning though there was no feedback or interference in the audio.

The AudiaX DGT-301 FM Transmitter is designed to conserve battery power by turning itself off in 55 seconds if no music is supplied. The addition of a DC adapter allows you to use the device in your car so long as it is plugged in.

With the exception of the AudiaX DGT-301 FM Transmitter not choosing good stations to broadcast on two times during testing the device functioned very well. Considering for the most part you will be setting stations in the four spot memory only once, you can overlook some of the problems with the automatic station locator.




  • Good sound quality
  • DC adapter included


  • Automatic station locator not perfect
  • Position sensitive

If you are looking for an FM transmitter for your MP3 player the AudiaX DGT-301 FM Transmitter is worth a look. The only real problem was the poor automatic station locator performance, but in different areas of the country this might not be a problem. The AudiaX DGT-301 FM Transmitter has great sound quality, though it was sensitive to minuscule position changes in my testing.
