FM Modulator / Transmitter Specifications

FM Modulator Type
This describes the kind of FM modulator or transmitter.

FM Modulators typically wire directly to the radio and provide an input source to the stereo. The input is activated when the stereo tunes into a specified frequency. These usually require some intermediate installation.
