FU-1000C has been applied in many large, medium, and small FM radio stations. This is due to its low price and excellent product quality. Being a budget-price and high-quality FM radio broadcast transmitter, the FU-1000C FM broadcast transmitter has been successfully attracted many radio station operators around the world.
Additionally, the FU-1000C broadcast FM transmitter can also be used efficiently in a variety of application scenarios, such as the most popular drive-in church broadcasting and drive-in theater broadcasting, etc.
In a word, the FU-1000C FM radio broadcast transmitter of FMUSER is able to broadcast more than you can imagine.
Let’s see why most people recommend this 1000W FM broadcast transmitter!
When purchasing an FM stereo transmitter, what elements should you pay attention to? Most people will consider the brand first, followed by the price. In fact, some parameters of an FM broadcasting transmitter are also important reference conditions for purchase. FMUSER hereby takes FU-1000C as an example in the following content to introduce several important parameters you should consider before purchasing a stereo FM transmitter.
First, you should consider its signal-to-noise ratio( AKA: SNR). When you or your customers run a radio station, what you want most is to let all the audience listen to the radio signal with little or no noise. If your radio station can’t send high fidelity signal, but full of noise signal, you may lose your loyal audience! FMUSER’s FU-1000C is an FM stereo transmitter with ultra-high signal-to-noise ratio (up to 92 dB, ordinary FM radio transmitter only has a signal-to-noise ratio of less than 80 dB). Just get a low budget FU-1000C FM broadcasting transmitter for your radio station, and you don’t need to worry about all kinds of annoying broadcast noise anymore!
Second, you should consider the stereo resolution (AKA: Separation). This is a common sense recognized by broadcasting experts: if the stereo separation is poor, the stereo sense will be weakened. The minimum stereo separation index stipulated by the International Electrotechnical Commission is greater than or equal to 40 dB at 500 Hz, which is also the value that most FM broadcasting transmitters can achieve. However, the FU-1000C stereo FM transmitter of FMUSER can achieve an amazing 73 dB! Do you want your radio audience to receive great stereo sound from the radio station you own? The FU-1000C fm transmitter for radio broadcast is your best choice！
What’s more, you should consider the distortion. As you know, not every signal you input to the stereo FM transmitter can be completely transmitted from the same position. Although the amplifiers of some imprecise FM audio transmitter undertake the function of signal amplification, they will also cause signal distortion. According to the complex distortion test results of FMUSER’s technical team, the distortion test result of FU-1000C FM audio transmitter is only 0.01%, which is far lower than that of ordinary broadcasting FM transmitter. This is such a blessing for those who pursue perfect radio FM transmitter!
Finally, you should consider its frequency response. The frequency response of ordinary power amplifier is about (+ / -) l-3 dB from 20 Hz to 20000 Hz; the frequency response of high-quality power amplifier is about + / – 0.1 dB from 20 Hz to 20 kHz, while the frequency response of FMUSER’s FU-1000C FM stereo transmitter is + / – 0.05 dB, which is one of the main reasons why FU-1000C can serve most professional radio stations.
Of course, you can use the accurate data obtained by FMUSER test team after testing FU-1000C radio FM transmitter as a reference to choose other FM stereo transmitters, but FMUSER sincerely hopes that you can benefit from your choice. If you think the above information are not complete enough and want to get more information about FMUSER FU-1000C high power FM transmitter, please continue to read!

The severing of the increased busy traffic, it is now interested in various countries in Africa to insert RDS signals when constructing a transmitting station, so as to realize the most economical broadcast of some traffic information by means of coverage of FM signals.
b) Traffic Program (TP):
With the TA and TP functions of RDS, RDS helps radio in-vehicle users to obtain traffic information faster, reduce congestion in the city, and increase the listening rate of the radio station.
c) Alternative Frequency(AF):
RDS AF help drivers automatic frequency switching between the Relay stations.
Inserting the RDS signal in the transmitter can also automatically switch between multiple different frequency broadcasts in the same program. The receiver automatically switches the substitute frequency AF by detecting the PI code in the RDS signal to ensure that multiple relay stations are passed. Broadcast stations that achieve nationwide coverage achieve seamless coverage and seamless listening. When the car passes the signal superposition zone between the two frequencies, the AF function of the RDS will automatically switch to the same program at different frequencies.
