50W FM Transmitter Stereo Broadcast

50W FM Transmitter Stereo Broadcast

50W 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.

• 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 50 watts, 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.

Features:

· Hearing similar to CD

· All-digital technologies DSP+DDS

· Built-in audio signal limiter

· Analog and Digital (AES/EBU) audio signal input directly.

· AGC circuit can keep the Output Power stability.

· Big LCD display all the parameters in real time.

· Compact structure

Equipments included

FREQUENTLY APPLICABLE USES:

1). Community Radio stations
2). LPFM radio stations
3). City radio stations
4). Christian Church radio stations

Warranty: 6 years for all transmitters in our factory.

OUTSTANDING FEATURES:
1) OVERHEAT PROTECTION: The transmitter will switch to auto-protection with alarm message and a beep sound once the working temperature gets higher than normal range.

2) OVER SWR PROTECTION: SWR is the indication of antenna system connection with transmitter. Once the connection is bad and causing a high SWR Value, the transmitter will switch to automatic protection mode by showing alarm message on the screen with a beeping sound meanwhile. 

3) FAN ERROR ALARM When the fan stops running, the alarm message will be displayed on the screen.

4) ADJUSTABLE POWER OUTPUT The RF out of this 50w FM transmitter is continuously adjustable from 0-50 watt at the stepping of 0.1watt, which means you can tune it to 1w, 1.1w, 1.2w...50w, with just one transmitter you’ll get multiple modes of outputs and easy to tune as per your needs
