Bảng Mạch Thu Tín Hiệu Radio Fm 87-108mhz Với Màn Hình Lcd Kỹ Thuật Số 3-5v Dsp Pll

1. the use of advanced digital audio signal processing (DSP) and FM ulation phase-locked loop (PLL) to make sound more realistic, more stable performance, long working hours without frequency offset
2. LCD display is more intuitive and accurate, with a very low power consumption and minimal noise, Can search for radio stations and store radio function, easy to operate
3. Built-in 30 digital volume adjustment button operation can be easily done, automatic power-down memory data before the power failure,speaker / headphone output automatic switching, quartz crystal frequency stabilization, the temperature change is no longer receiving frequency drift
4. The professional audio DSP audio signal analysis and processing, automatic mute no signal or weak FM signal noise floor of the big time, away from the traditional FM radio signal or the signal is weak in the absence of annoying when rustle, digital incremental rotary encoder to adjust the volume and frequency of use feel good, precise positioning, stable and durable, 360 ° rotation without dead ends
