DFM-1000    1000W FM Transmitter

The DFM-1000 has integrated multi-band DSPX audio processing that means stations without a dedicated processor sound great, right out of the box. It also has one of the industry’s clean- est exciters and an ultra-low distortion modula- tor which go to make it a highly stable FM transmission system. Clean, loud, market leading audio performance that will crush the competition.
