Product selling point:
1. Using advanced digital audio signal processing technology (DSP) and FM phase-locked loop modulation technology (PLL) to make the sound quality more realistic, the performance is more stable, and the working frequency for a long time has no offset
2. The LCD display is more intuitive and accurate
3. Built-in 30-level digital volume adjustment, easy to complete by key operation
4. Automatically memorize the frequency before power failure
5. Support serial AT command control
6. The chip-type high-precision quartz crystal is used to stabilize the frequency, and the transmission frequency will not drift when the temperature and voltage change.
7. Support Bluetooth audio to FM transmission and line input audio to FM transmission
