Warm tips:

1. In advanced mode, all settings and parameters cannot be changed including time, please return to standard mode to adjust if needed.

2. For safe shipping, the remote control not include batteries(2*AAA), please prepare it by yourself.  


Features:

1.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, month error within 10 seconds, very cool and interesting.

2.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 line 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. 

3.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.

4.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.

5.Multi-function mode: clock mode, music mode (level light mode, spectrum mode).

6.The clock brightness and level brightness can be adjusted in 15 levels respectively, and the clock brightness can be set at two different time periods.

7.The rising speed, falling speed of the main body of the level light, the holding time of the peak light, and the falling speed can be adjusted individually.

8.Accurate and simple clock display function (this function is entered after 30 seconds without signal input and key operation).

9.When the microphone is input, it has the function of ambient noise filtering, which can adapt to more working environments.
