Product Description 10KW FM Stereo TransmitterThe 10KW FM Stereo Transmitter (Hot-plugin) is a high-performance broadcast-grade stereo FM broadcast transmitter for wireless coverage of professional broadcast stations. Considering the high reliability of the transmitter, in the design concept, the transmitter adopts redundant design in key parts in order to achieve long-term stable operation of the transmitter. Because of the hot-plugin structure, the transmitter's components can be repaired and restored without stop working.FEATURES Redundant Large Power: 8pcs 1.5KW hot-plug RF Amplifier modules combined high efficiently; Maximum Output Power is 11KW. It uses the new high-efficiency LDMOS Transistors, the full RF output power can reach 70%. Redundant Power Supply: 6pcs 3500VA switched power supply modules are working in parallel. It can provide large redundant power capacity.High-performance Low Pass Filter which can minimize unwanted emission.Output Power Stable: Total output power is extremely stable by AGC (Automatic Gain Control). Ensure the output power would not change with the boot time and ambient temperature, power stability is less than 10W.Dual-Exciter: Two exciters (DSP+DDS) with automatically changeover switcher, increase entire transmitter stability.Analog and Digital (AES/EBU) audio signal input directly; Hearing similar to CD. Friendly man-machine interface: 8-inch true-color touch LCD display, real-time display of various parameters in the machine, without any training, you can operate under the screen prompts.Intelligent protection functions by centre control module, like Over Forward Power, Over SWR, Over Temperature, Over Voltage, Over Current. It can adjust output power intelligent, keep the maximum safe output power and keep fault not expanding.Best dustproof performance: All inlets are made of high-quality filters which can filter out dust in the air to keep stability of transmitter.Best lightning protection: high quality lightning protection SPD from Germany for the whole power supply.Real Hot-Plug structure: the Amplifier modules and Power Supply modules can be repairing at non-stop condition in any case.Timing automatically adjusts the output power: After setting, the transmitter can automatically adjust the output power at different times of the day, convenient for economical radio broadcasting.Advanced Remote Telemetry Interface: RS232/RS485 or TCP/IP Internet Communication interface is ready for remote control system which can read all detail parameters from transmitter.Technical Specifications: 1.

Chassis dimensions 19 inches wide (850mm) × height (1970mm) × depth (1200mm)26. Transmitter weight 550kg Compay Show:Common Problems: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. Is your Analog TV Transmitter can be upgraded to Digital?A7. Yes, we can. But the Frequency Band should be the same.The only difference between Analog & Digital TV Transmitter is its TV Modulator.After upgrade to Digital, the Power from TV Transmitter reduced 5 times.For example: 1KW analog TV Transmitter can be upgraded to 200W Digital TV Transmitter. Q8. 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. Q9. 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. Q10. 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.Mike Cai International Sales DirectorZHC(CHINA) Digital Equipment Co., LTDAdd: Building 5th, No.23, Jugong Rd.
