FMUSER FMT5.0-50H 50Watt FM Transmitter FM Broadcast Radio Transmitter FM Exciter For FM Radio Station/Drive-in Church Service/ Cinema/Parking Lots

Introduction:

FMT5.0-50H FM radio transmitter is highly reliable, lighter in weight and easier to operate than previous version of transmitter. This transmitter adopts a simple-style design concept. It integrates the 50W FM stereo transmitter exciter, power amplifier, output filter and switching power supply in a 1U high 19-inch standard case, reducing the connecting cables between the components.



Features:

• User-friendly digital LCD panel, using one rotary knob to control.

• The integrated LCD screen displays all the parametric including: transmitter frequency, stereo and mono, volume, amplifier tube temperature, audio signal UV meter, forward power, reflected power, modulation mode, pre-emphasis etc,.

• 1U 19-inch thickened all-aluminium case, strong and excellent heat dissipation.

• Precise PLL frequency generation system, to ensure that the frequency not drift away for more than10 years, with built-in high-quality stereo encoder.

• Outstanding power AGC balance control system, adjustable power output from 0 to 50watts, and automatic gain power control to maintain output power within set range without drifting.

• Signal input supports XLR and RCA audio inputs, and also SCA and RDS signals using the BNC connector AUX.

• The RF amplifier uses LDMOS transistors to withstand even severe load mismatch exceeding the 65 : 1 VSWR at a 5dB compression point.
