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 inputFrequency Agile from front panelSWR metering from remote controlAbility to control output power from remote control5-Year warrantyMeets or exceeds all FCC requirementsTo see the owners manual for the Crown FM 30, click on this.87 to 108MHz (Japanese frequency available 74-90MHz as an option) Front panel agile3 to 30 watts with front panel adjustment50 Ohms unbalanced1.7:1 Maximum with automatic foldback at higher VSWRBetter than +/- 1KHz over operating temperature rangeDirect Frequency Modulation of CarrierLED Indicators with Peak indicatorsBetter than 60 dB (70 to 80 dB typical)Better than 50 dB referenced to 100% modulation @ 100 Hz, no de-emphasis.Better than 50 dB with 100% modulation @ 100 Hz, no de-emphasis (typical >60dB)Better than 65 dB (75 dB typical)+/- 120 KHz, better than 35 dB; +/- 240 KHz better than 45 dB0 to 50 degrees C0 to 80% @ 20 degrees C (non-condensing)10,000 ft (3,000 m)100 to 120 or 220 to 240 volts AC +/- 10%, 50 to 60 HzGreater than 97% (lagging)36 to 48 VDC (48V required for full output)100VAMeets FCC requirementsStandard type N, 50 Ohm5.25 x 16.5 x 17.5 inches (13.4 x 41.9 x 44.5 cm) exclusive of rack mounts but inclusive of connectors25 pounds (11.3 Kg) shipping weight = 33 Pounds (14.9 Kg)13.8 Vp-p for +/-75KHz deviation< 0.05% from 50Hz to 15 Hz (0.03 typical)33.8 Vp-p for +/-75KHz deviation+/-0.3 dB from 40Hz to 100KHz*Please consult a broadcast engineer to determine if this unit is right for your application and you are meeting all of the appropriate legal requirements.
