Advantage:
Support 24bit 48khz wav file, the sound quality has reached the master level. Sound three-band equalizer, clear, structured. pcb layout neat and clean, analog to digital strict distinction. This is not to reduce low-noise and disturbance. More important is to reduce the storage capacitor and the electrical potential difference between the elements, while using a proprietary chip decoder chip mute processing technology, the use of separate left and right channels of DAC to deal with noise when the sound becomes mellow, sweet, natural permeability ( chip made confidential treatment). Under MP3 mode can not hear any background noise, with a charming mellow tone. At the same time with power and memory function, position the next boot automatically play when the last shutdown from start playing.
