Car Home Voice Control Line Control VFD Fluorescent Screen Music Spectrum Level Indicator Digital Clock Aluminum Frame

Description Aluminum alloy CNC integrated molding shell size 141 X 47 X22 5 MMMulti function mode clock mode music mode level light mode spectrum mode Clock brightness and level brightness can be adjusted in 15 levels and the clock brightness can be set in two different time periods Level body s rising speed falling speed peak lamp holding time and falling speed can be adjusted independently The main falling speed of the spectrum the holding time of the peak light and the falling speed can all be adjusted independently Accurate and simple clock display function enter this function after 30 seconds without signal input and key operation SD3078 has built in crystal oscillator and resonant capacitor The chip has a high precision compensation method to achieve a high precision timing function over a wide temperature range Among them the accuracy at 25℃ is ±3 8ppm that is the monthly error is 10S Software A G C algorithm to ensure that the output effect of the input signal is ideal in a small to large range The unique spectrum smoothing algorithm allows the spectrum to achieve the best balance between real and visual aesthetics Line input and microphone input selection When the microphone is input it has the function of environmental sound filtering which can adapt to more working environments Clock microphone wake up function Try to reduce the uneven display of the screen caused by the screen lighting for a long period of time in the clock mode VFD scree
