600-Watt FM Translator - Includes Built-In Receiver


Crown FM600R
The FM600R is an economical stand-alone 600W FM translator with a built-in receiver that delivers a high level of performance for today's broadcast needs.

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:

• Translator with built-in receiver
• 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
