ZHC618F-3000W Compact FM Stereo Transmitter
ZHC618F-3000W is a compact FM stereo broadcasting transmitters. The advanced digital technologies, Digital Signal Processor (DSP) and Digital Direct Synthesizer (DDS), are used in the transmitters to get little size, high performance and high reliability. They are widely used for professional radio stations to transmit high quality FM radio programs.
FEATURES:
1. The simple design of 3KW FM stereo transmitter, exciter, power amplifier, output filter, switching power supply, etc. are installed in a 4U high 19-inch standard chassis, reducing the connection cables between ordinary transmitter components, and more reliable High, easier operation.
2. The whole process of digital processing (DSP + DDS), to achieve the perfect hearing effect close to CD sound quality.
3. Analog audio and digital audio (AES / EBU) can be input at the same time, digital audio has priority.
4. With TCP / IP, CAN and RS232 communication interfaces and SMS cat interface.
5. Perfect alarm and protection functions for over current, over voltage, over temperature, over power, and excessive standing wave ratio.
6. Large screen LCD displays working parameters in real time.
7. Large radiator and two high-speed, long-life fans are used to ensure that the transmitter works at a reliable low temperature.
8. Use high quality, high reliability, wide range switching power supply.
9. High-quality stainless steel, 4U, 19-inch standard chassis.
10. The machine has high reliability, high performance, easy operation and low price.

Common Problems:
In order to be more comprehensive understanding of the knowledge about our products,we collect all the analyses of problems for every order,hope it will help you.
Q1. What these equipments used for?
A1. We are original manufacturer in FM Radio & TV Broadcasting equipments; they are professional used for FM Radio & TV Broadcasting Station (Transmitting equipment.)
Q2. What equipment & solution your company can provide?
A2. We can do complete solution for FM Radio Station System. It includes:Studio--Link--Transmitter--Cables--Antenna.
We also can provide complete Transmitting part of TV Station. It includes:Link-Transmitter-Cables-Antenna.
Q3. How large areas can One Station cover?
A3. One FM or TV Station can cover one city or one town.
The Maximum cover ranges of one station can not over 100KM Radius because the Earth is Curve.
You can use Multiple Stations & Different Frequency to cover larger area.
Q4. How do I choose suitable equipments for my station?
A4. The most import factors are Power and Frequency.
We need to know the Power and Frequency you need exactly.
How long the distances do you want to cover in Radius?
How height your Antenna can be installed?
Q5. How to calculate Broadcasting equipment Cover Range?
A5. The Cover Range depends on 4 factors:
1. Power from Transmitter; 2. Height of Antenna; 3. Gain from Antenna; 4. Around Environment.
Then we can know the cover range of your station.
Q6. Is the Frequency Adjustable?
A6. FM Radio Band Frequency is 87~108MHz, TV Band Frequency includes UHF/VHF band.
For FM Radio Transmitter; Power Below 2KW is all adjustable. Above 2KW would be narrow.
For TV Transmitter; all Frequency Band is very Narrow, only can contain around 3 Channels; so it's not adjustable.
Q7. How to do installation of these equipments?
A8. For small power station, the equipments are very easy for installation.
For large power station, we can send our engineer to your country to help you do the installation, but you should pay the cost.
We also can do training for your engineer here in our company.
Q8. How to operate these broadcasting equipments?
A9. We provide All-English user manual; All-English operation software in our equipment.
We also can do training for your engineer here in our company.
Q9. What about after sales?
A10. The warranty time is one year after goods leaving factory.
We can provide technical support from internet or in our company.
We can send spare parts to you directly when the equipment damaged.
