FM Transmitter Module 3.3-5.0V 3Wx2 DSP PLL 50Hz-18KHz Frequency LCD Digital Display with Wireless Microphone Audio Transmission |

Product features:   

1: The use of advanced digital audio signal processing technology (DSP) and FM phase locked loop modulation technology (PLL) makes the sound quality more realistic, performance more stable, long-time working frequency without offset.  

2: LCD display is more intuitive and accurate, with extremely low power consumption and minimal noise interference.  

3:   30 level digital volume adjustment, key operation can be easily completed.   

4: Power down automatically memorizes the data before power off.   

5: Automatic switching of speaker / headphone output   

6: Quartz crystal is used to stabilize the frequency, and the receiving frequency will not drift when the temperature changes.  

7: The professional audio DSP is used to analyze and process the audio signal. When there is no signal or the signal is weak, it will automatically mute when the FM bottom noise is large, so as to get rid of the annoying rustle of the traditional FM radio when there is no signal or the signal is weak.

8: Incremental digital rotary encoder is used to adjust the volume and frequency, with good hand feeling, accurate positioning, stable and durable, 360 ° There is no dead angle in rotation.

9: 30 level digital volume adjustment range

10: Support serial port communication control, can use computer or MCU with serial port equipment control module all functions.
