This device is a stereo frequency modulation emitter and can be used za portable additional radio. Convert audio to high frequency modulation transmitted by air za via antenna for remote radio reception. Suitable for individual transmission, campus radio and other scenarios. The panel is equipped with two frequency controls up to 1 MHz or 0,1 MHz and power settings ranging from 10 mW to 500 mW (11 precision in total). It also has a memory function that automatically turns on the settings for use with the device. Features: (Emiter): This device is a stereo frequency modulation emitter and can be supplied za portable ordinary radio. Convert audio to high frequency modulation transmitted by air za via antenna for remote radio reception. Suitable for individual transmission, campus radio and other scenarios. ( Precise frequency and power control): The panel is equipped with two frequency controls up to 1 MHz or 0,1 MHz and power settings ranging from 10 mW to 500 mW (11 precision in total). It also has a memory function that automatically turns on the settings for use with the device. (Type C interface and compatible operation): For the device uses universal USB Type C interface, agree to acceptance compatibility for performance and transmission quality thanks to power supply to control the load controlled by unstable currents. (Wide frequency range and clear sound source): The frequency band of this device ranges from 76 MHz to 108 MHz and offers 320 transmission frequencies. The 10 to 500 mW power supply provides different distances and environments. The audio input uses a standard 3,5 mm interface, application to noise of 63 dB and low distortion coefficient, which ensures the quality of the sound transmitted. (Professional situation over long distance): Under favorable conditions (power 500 mW, excellent antenna configuration), the maximum transmission distance can be available for 2000 meters, so that broadcasting can be used on outputs in spaces. It features a LCD display for visualizing the current frequency and has a compact feature for easy installation and portability.
