300-Watt FM Exciter - Composite Input Only

BSW PART: FM300E

FM300E
The FM300E is an economical stand-alone 300W 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 FM300E Features:
• Basic exciter with composite input
• Frequency Agile from front panel
• SWR metering from remote control
• Ability to control output power from remote control
• 3-Year warranty
• 24-hour service support
• Meets or exceeds all FCC requirements
