30-Watt FM Exciter - Composite Input Only


Crown FM30E
The FM30E is an economical stand-alone 30W FM transmitter that delivers a high level of performance. It is a basic exciter with composite input only.

Featuring low loss circuit boards and copper heat spreaders in the RF chain, it functions with less heat and improved life span. A robust power supply with switching voltage and power regulators for AC or DC operation let you use it anywhere power can be generated.

Crown Broadcast FM30E Features:
• Basic exciter with composite input
• Frequency Agile from front panel
• SWR metering from remote control
• Ability to control output power from remote control
• 5-Year warranty
• Meets or exceeds all FCC requirements
