DIY Dual 12 Level Stereo Indicator, Audio Spectrum Display with AGC Mode, Adjustable Light Speed Level Meter Board Module, LED VU Meter

AUTOMATIC SAVE FUNCTION: Once the settings are changed, the data is automatically saved every 5 seconds. When the data is saved, the data will remain off and the data will be saved multiple times because the factory data will be saved for the first time. Power or other settings and operations! If you change the power immediately after the change, the changed data will not be saved
ULTRA-SMALL STEREO LEVEL LIGHT: Adjusts the light bar rise, descent speed and lamp stop time. Users can freely adjust the main top of each light bar and actual light speed, which is most suitable for their own display. Each lamp is equipped with an independent current limiting resistor to ensure the same brightness of different color lights. The input is isolated by the op amp to avoid single-chip high-frequency interference AUDIO
DISPLAY EFFECT MODES: Multiple display modes available including Strip Show with After Top Travel Whereabouts, Strip Show After with The Disappearance Of The Top Travel, The Strip Display without Top Display, Strip Show with Right After The Top Disappears, The Strip Display with Three Lights, Striped Marquee Display with Top Effect, and Top with Strip Show Right Jump Lamp Lights Two Bits Whereabouts
AUDIO INPUT ISOLATION: Audio input is isolated by TI to minimize monolithic high frequency interference in series audio circuits. Different colors of light provide separate current limiting resistors to guarantee match. This level lamp has standard display mode and wide range of automatic gain control AGC Mode with rich functions
PROFESSIONAL DB MODE: The V1.2 version software adjusts the previous real-time mode to a professional DB mode, which can be installed in professional related equipment for monitoring purposes. The audio amplitude range is -40dB to +9dB, which has professional reference significance. For some users that the level of light sensitivity, please complete the user welding test the first thing must press the button for 10 seconds to a factory settings
OPERATING SPECIFICATIONS: Operating voltage range of 7v-12v with 100mA current consumption. Features 7 Green, 2 Orange, and 3 Red LED indicators for clear visual representation of audio levels across the dual 12 level stereo spectrum display
ADJUSTABLE SENSITIVITY AND AGC: Wide range automatic gain control mode allows for flexible sensitivity adjustments to match various audio sources and environments. Factory reset option available by pressing button for 10 seconds to restore optimal default settings
