100% brand new and high quality
Material: Electrical components
Color: See pictures
Product Features:
1: The use of advanced digital audio signal processing (DSP) technology and FM modulation 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 very low power consumption and minimal noise interference.
3: Built-in 30 digital volume adjustment, the key operation can be easily completed.
4: automatic memory before power down the volume and frequency of information
5: multi-channel audio input automatically switches
6: High-precision SMD quartz crystal frequency stabilization, temperature, voltage changes the transmission frequency is no longer drift
7: supports serial command control
