Features: Advanced Digital Audio Signal Processing (DSP) and FM Phase Locked Loop Modulation (PLL) technology ensure less sound distortion and more stable performance. The LCD display is more intuitive and accurate, has very low power consumption and tiny noise interference. Automatically save data when power fails. Automatically switches between speaker and headphone output. The use of quartz crystals for frequency stabilization and the reception frequency do not drift when the temperature changes. Use professional audio DSP to process and analyze audio signals. Mute automatically when there is no signal or weekly signal as large FM floor noise to eliminate the annoying rustling of conventional FM radio. Use the incremental digital 360° rotary encoder to adjust volume and frequency. This is accurate, stable, durable and also offers a comfortable hand feeling. 30-class digital volume adjustment range. Supports serial communication control, allowing you to use computers, MCU and other devices with serial port to control the module.
