Feature(may vary by option.)

●Note: The main board and acrylic board are packed separately, but only a few screws can be assembled. (It is very easy so even amateur can do it)
●ACCURATE MUSIC SPECTRUM ANALIZER AND WATCH DISPLAY: Adopts a dedicated VFD display screen with 25 x 15, ensuring accuracy of each frequency band. In addition, the high-precision clock display using the SD3078 built-in crystal oscillator ensures the watch accuracy of ±5 ppm, and a month error within 10 seconds
●Wide frequency range display and 3.5mm AUX input/MIC input:Support 20Hz ~ 20KHz frequency sweep, high precision display and frequency point test. The 3.5mm AUX and high-sensitivity MIC pickup make it perfect for wired and wireless connections, so you can easily see every subtle change in the sound
●Special AGC Algorithms and Customized Output Curve: Special AGC algorithms ensure ideal visual effect even when input signal is in a range of small to large, avoiding full-screen display when low signal is not displayed. (You can switch the gain between -10/-5/-3/-1/0dB. 3 different display modes: Actual Output/Smooth Output I/Smooth Output II ensures accuracy and high level of display effect, meeting various usage requirements
●Many adjustable items and display effects: you can adjust the brightness, main light column drop speed, retention time and peak drop speed independently. 5 music spectrum display modes and 2 clock display modes for you to choose. All settings have power off memory function, so you dont have to set it again after a restart
