Features 

• Accurate sound level meter & audio spectrum analyzer & clock: adopts dedicated OLED display screen with 256 × 64 high resolution, guarantee the accuracy of each frequency band. Also with high-precision clock display, using SD3078 built-in crystal oscillator which can ensure that the clock accuracy is ±3.8ppm, year error within 1.2 minutes, very cool and interesting.

• Wide frequency range display & dual signal inputs: support 32Hz-16KHz frequency sweep, 8 kinds of frequency bands for free choice, high-precision display even can do frequency point test. Support 3.5mm AUX and microphone inputs, compatible with your phone/PC/game player/speaker, easily to see the music level status in real time and every slight change of sound can be shown visually. 

• Speical AGC algorithm & customized output curve: ensure ideal visual effects even the input signal is in a small to large range, avoid that no display when input low signal and display in full screen when input high. Audio spectrum display with 3 modes: real output / smooth output I / smooth output II, both ensure accuracy and best display effects, satisfy different usage requirements.

• Many adjustable items & display effects: the brighntness, the falling speed of main light column, the holding time and the falling speed of the peak can be adjusted separately. 3x6=18 sound level meter display effects, 9x8=72 music spectrum effects and 3 clock display modes for free choice,  and all settings with power-off memory function, no need to set again after restarting.
