FMUSER FM Broadcast Relay Station Radio Relay Repeater Set Model:FSN-1000R
OVERVIEW:
FSN-1000R FM radio relay repeater is the latest product developed by FMUSER in 2019. The all-in-one product includes digital demodulation, digital processing and modulation, RF power amplifier, power supply, all modules in a 2U standard chassis, all signals both input and output from the rear panel.
FSN-1000R FM radio relay system includes receiving antenna,FSN-1000R FM radio relay repeater, transmitting antenna, connecting cables and connectors. The FM signal can be received by the receiving antenna, the FSN-1000R FM relay repeater will do demodulates, processes, modulates, RF amplifies, and the transmitting antenna can directly broadcast again , this system can meet the needs of various occasions.
Many users also call it as local: fm relay station, broadcast relay station, relay transmitter, complementary station, broadcast translator, repeater, re-broadcaster.
How to expand my fm transmitter coverage , if you already have a radio station, ?
You can use the FMUSER FSN-1000R FM radio relay system to receive the FM signal of the main station and broadcast it again at the new station. The power of the FSN-1000R relay broadcasting system transmitter is 1KW, so the coverage of 50KM can be increased for each additional station. And the source of the studio program is exactly the same as the main station.
How to re-broadcast your own station to whole country of 100KM-200KM with a limited budget?
The same principle is as above, five sets of FMUSER FSN-1000R relay broadcasting system can meet the demand, and reduce the waste of signal coverage in the unmanned area, only need to be placed in a densely populated place.
How to transfer the studio audio to the transmitter?
As we all know, STL can achieve this function, but STL must be accessible point-to-point transmission. If there is a mountain or other obstacles in between, you can use FM Transmitter to broadcast the audio from studio to transmitter, because the FM RF signal can be bypassed, and finally the FMUSER FSN-1000R repeater can receive high quality audio from the studio.
How to transfer studio source to transmitter stations in different locations?
STL can only be point to-point. If there is a one-to-many point, multiple sets of STL systems must be used, and the price is high, the installation is troublesome, and it is seriously affected by the environment. Now we only need to install the FMUSER FSN-1000R relay broadcasting system at different transmitter sites, which solves the problem of program transmission and also solves the problem of broadcasting stations, because FMUSER FSN-1000R is not only a receiver but also a broadcaster.
In short, FMUSER is always working on the most economical, stable and reliable system solutions to solve customers’ problems in broadcasting.
The FMUSER FSN-1000R relay system has many other main features as follows:
MAIN FEATURE
1. Adopt digital FM receiving and demodulating technology to ensure clear demodulation sound quality.
2. Using FPGA+DDS technology to implement full digital FM modulation technology, so that the FM emission index reaches the top level.
3. Using high reliability ARM architecture microprocessor technology as the main controller.
4. Support input of wireless RF receiving audio, two AES/EBU digital audio signals, one analog stereo audio and one MPX stereo composite signal, etc.
5. Support one way RDS or SCA input.
6. AGC controls output power to ensure zero deviation of output power.
7. Perfect over-current, over-voltage, over-temperature, over-power, standing wave ratio alarm and protection function.
8. Using OLED to display working parameters in real time.
9. Use high-gain directional FM receiving antenna to receive signals (even the signal is very weak ) and and re-broadcast .
10. Re-broadcast power up to 1000W, with high gain dipole antenna, cover radius up to 50KM.
Schematic
Applications
1. Customers who has a main radio station and want expand coverage.
2. Make up coverage in mountainous areas.
3. Limited budget to expand coverage of the radio station.
4. 100KM or 200KM coverage , even for whole country coverage.
5. 360 degree omnidirectional transmission studio program.
6. There are obstacles between the studio and the main radio station.
