1.2. The LCD display is more intuitive and accurate, with very low power consumption and minimal noise. It can search for radio stations and store radio functions, making it easy to use. 2.1. Advanced digital audio signal processing (DSP) and FM modulation phaselocked loop (PLL) technology deliver more realistic sound, stable performance, and longer uninterrupted operation. 3.4. Professional audio DSP analyzes and processes audio signals, enabling automatic muting when there is no signal or weak FM signals. It eliminates prolonged noise interference, avoiding the usual static or rustling sounds when the FM signal is weak or absent. The digital incremental rotary encoder ensures smooth and precise volume and frequency adjustments, with a comfortable feel, accurate positioning, and stable durability. It supports 360° rotation without dead zones. 4.3. The builtin 30 digital volume control buttons allow for effortless operation. It features automatic poweroff memory retention, automatic switching between speaker and headphone outputs, quartz crystal frequency stabilization, and resistance to frequency drift caused by temperature changes.
