2 pièces Module de Microphone FM Transmetteur V4.0 Professionnel 0,7-9V

Résumé

• Manual Knob: FM transmitter pickup module uses manual knob to find the station more accurately, you need to manually input the receiving frequency carefully, such as input 88.1MHZ ,88.2MHZ, 88.3MHZ.... .108.0MHZ.
• Long Range: FM emission mic core board using 9V power supply, 0.7m/2.3ft wire as antenna, open place transmitting distance of 50‑100m/ 164.0‑328.1ft, the actual communication distance varies depending on the environment, antenna location, receiver Sensitivity, etc. are different.
• Through the Wall: FM transmitter pickup board can penetrate the wall, depending on the wall reinforced concrete structure, thickness and density, the general wall can wear 2‑3 block, through the wall capacity by the specific antenna placement, battery voltage, radio sensitivity decision.
• Battery Power Supply: FM transmitter pickup module can use common batteries, the higher the working voltage the greater the transmitting distance, the greater the battery capacity the longer the working time, the actual working time to the actual battery capacity shall prevail.
• Parameters, Materials: FM radio transmitter module working voltage is ultra wide 0.7V to 9V; frequency adjustment range is wider than 88‑108MHZ. premium PCB material, high density, safe and reliable, aging resistance.
