Features:
1: The advanced digital audio signal processing technology (DSP) and FM phase-locked loop modulation technology (PLL) are used to make the sound quality more realistic, the performance more stable, and the long-term working frequency has no offset.
2. LCD display is more intuitive and accurate, with extremely low power consumption and minimal noise interference.
3: Level 30 digital volume adjustment can be easily completed by pressing the key.
4: Automatic memory of data before power failure.
5: Automatic switch of speaker/headphone output
6: Adopt quartz crystal 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, the audio signal will be automatically muted when the FM background 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: The incremental digital rotary encoder is used to adjust the volume and frequency. It has good hand feeling, accurate positioning, stability and durability, and 360rotation has no dead angle.
9:30 digital volume adjustment range
10: It supports serial communication control, and can use all functions of equipment control module with serial port such as computer or MCU.
