Product Description

ZHC618F-30W~300W/5G FM Transmitter (Exciter)
300W FM Boardcast Transmitter for Radio Staion


1. Overview
ZHC5G series FM stereo broadcast transmitter (exciter) is an outstanding software radio product; it is designed with high reliability concept and has unparalleled performance indicators.

This transmitter uses a new large-scale field-programmable gate array (FPGA) and direct digital frequency synthesis (DDS) technology up to 5G, which has achieved the highest technical specifications in the industry so far, it'providing listeners with CD-like sound quality.

The transmitter consists of audio interface unit, digital processing and FM modulation unit, radio frequency power amplifier unit, human-machine interface unit, communication interface unit, clock synchronization unit and power supply unit. The transmitter is installed in one 19-inch 2U standard case, and all input and output signals are led out from the rear panel.

2. Technical characteristics and principle block diagram
Product technology has the following technical features:
• Full process digital processing to achieve a perfect auditory effect of CD-like sound quality
• Full-scale digital processing with large-scale field-programmable gate array (FPGA) technology
• Direct digital frequency synthesis (DDS) technology at speeds up to 5G to peak transmitter specifications
• High reliability microprocessor (ARM) technology as the primary controller
• Support for multiple audio source inputs (transmitters can be automatically selected by priority): 
 Two AES/EBU digital audio signal inputs (highest and second priority)
 One analog stereo analog audio signal input (3rd priority)
 One MPX stereo composite signal input (4th priority)
One I2S digital audio signal input (lowest priority)
• Supports one RDS or SCA subcarrier input
 Support stereo pilot signal and stereo composite signal 19KHz/MPX output
• Upgradeable to FM Synchronous broadcast transmitter
• Electronically controlled AGC controls output power zero drift
• Perfect over-current, over-voltage, over-temperature, over-power, standing wave ratio alarm and protection
• One-touch shuttle quick keyboard input
• Real-time display of operating parameters using OLED
• With TCP/IP, RS232, RS485, CAN communication interface and SMS modem interface
• 19-inch standard chassis, height 2U

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.
