Features:
This unit includes all the components and circuit boards fully tested and assembled inside a box. Other items include,(8GB SD card with a songs card only in a 7-watt version), a BNC connector, antenna key items & audio cable.
A volt, 2/5A SMPS power supply with DC pin is required and supplied
The 7 W FM transmitter has a control panel with a dot matrix LCD display screen and 3 key buttons to change frequency, volume, and range by changing the output transmitting power.
Control panel: 58 x 36 mm (as shown in the picture)
The range/distance in free air without any obstructions: 7 watts with Yagi antenna good directional coverage with Yagi antenna is about 14 KMs, with a dipole of about 10 KMs (Guaranteed if our dipole is used), Please note any antenna is an optional extra cost.
Transmitter key features:
1, Digital technology makes the frequency more stable, the frequency does not change with the environment and produces frequency drift.
No need for any adjustment inside.
2, But the frequency can be adjusted digitally by buttons within the specified scope.
3, The 7-watt has a micro SD socket to use any 8GB (or more) card holding 100’s of old MP3 Bollywood cinema songs and one can add more than 6000 songs from any computer through the SD card adapter supplied.No need to use any external audio feed into the aux socket.—
4, Also with the microphone input interface. With 2 mics stereo transmission can be done. All through the digital potentiometer, it is easy to control the volume of the microphone (supplied at extra optional).
5, Audio input ay aux also by a digital potentiometer to adjust the volume.
6, Transmitting Power can be changed between 0.5 W and 7 W maximum having continuous adjustments features to adjust the range from 100 meters onwards to KMs.
7, The power output network for harmonic suppression is very good, so as to make the output spectrum cleaner.
8, Set the frequency and power once and the next time boot does not need to do the setup again!
Main parameters:
1, The input voltage: DC 12 v
2, Mic extra
3, The audio signal at Aux: The maximum input Vpp is to be less than 1 v.
4, Microphone types accepted: Any condenser microphone/s
5, The output power: 0.5 W – 7 W continuously adjustable!
6, The output impedance: 50 Ω for antenna
7, Working frequency range: 76 m – 108 MHZ
8, Frequency step of 0.1 MHz for adjusting
9, The distortion degree: 0.03% ~ 0.1%
FAQ:–
How far (long) the transmitter will cover?
The transmission range depends on many factors. The true distance is based on the antenna installing height, antenna gain, using environment-facing buildings and other obstructions, the sensitivity of the receiver, and the antenna of the receiver. Installing the antenna at a higher height and using it away from cities, the distance will be much longer.
EXAMPLE:- 7 W FM Transmitter used in the city and village with GP vs Dipole Yagi antenna:
I have many customers in India who use this 7 FM stereo transmitter with a home-built GP antenna and they have tested it with a car FM radio (not cell phone FM radio) and, it covers a good range in a city area with clear sound and no hissing noise. The distance can be high while using a homemade directional Yagi antenna or buying a dipole / Folded Dipole antenna.
Most Important
Antenna either Yagi, dipole or GP (ground plane) must be used in this transmitter with 50 ohms coaxial cable RG58( Not the type used by cable tv operators). The cable is provided with GP / Dipole / FD antenna is included as selected.
Package includes :
(1 )7 FM stereo FM transmitter in a white acrylic box with LCD Screen on top having 3 button switches for adjustment.
(2)Mic extra
(3) One aux cord
(4) Two BNC connectors for antenna already connected with the cable selected
(5) One 8GB (or more) Sd card with many songs ( supplied with the unit)
(6)(Optional) Complete FD antenna -with a base unit and female BNC connector optional on selection
(8) (Optional) RG58 copper Coaxial cable coil suitable length as selected
(9) Circuit Diagram ( We give it as because we are manufacturers) No one dares to give it.
(10) One operating manual in English
Included -- One 12-volt 2/5/10 A, SMPS DC supply adapter for 100 to 240 volt 50/60 Hz ac input, with DC output pin. (The adapter may not be the same as shown in the picture)
Disclaimer:-Please note any FM Transmitter having a power output of more than 100 mW ( is 0.1 watt ) requires a license from the government to be used in any place without which it is illegal. We are not responsible if anyone uses our products without a valid license.
