Crown Broadcast FM600T

Ideal for the medium power broadcaster, the FM600T is an economical stand-alone 600W FM transmitter with a built-in audio processor and stereo generator that delivers a consistently high level of performance.

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.

Main Features:
• Transmitter with a built-in audio processor and stereo generator
• 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
