LED VU Meter with Spectrum Display for Audio Levels in 12V/24V Applications, Offers Adjustable Lighting Effects and Signal Processing (A)

• [SMALL FOOTPRINT] Compact PCB size of 80x14mm with an LED module area of 58x14mm makes it suitable for various installations without taking up much space.
• [USER-CUSTOMIZABLE SETTINGS] Adjust the speed of light bars and main light to create a unique display that resonates with your audio output.
• [REDUCED INTERFERENCE] Designed with TI signal isolation to effectively reduce high-frequency noise from connected circuits, reliable performance.
• [COMPREHENSIVE WIRING GUIDE] Includes straightforward wiring instructions for quick and easy integration into your existing setup.

Features: 1. Smallest volume, PCB size 80*14mm LED module area: 58*14mm 2. With multiple functions, users can freely adjust the actual speed of each light bar and the main light. 3. The audio input uses TI signal isolation to minimize the high-frequency interference caused by MCU series connection to the audio circuit. 4. Different color lights provide current limiting resistors. Important tips: 1. During the sampling time, the microcontroller makes the dual-channel parallel input signal change rapidly, and the amplitude displayed by the two light bars may be different, which is normal. 2. In extreme cases, there may be very slight high-frequency noise. It is recommended to replace the signal input line with a two-core shielded line. 3. Working voltage: 7-12V current above 100MA can work. Disabling voltage above 12V or reverse connection of positive and negative poles will cause a certain degree of optical damage Visual effects: 1. Display area + position after tripping peak 2. Bar display + after peak disappears 3. Bar display + (no peak display) 4. Right key display + after maximum value disappears 5. Bar display + (three lights) 6. Bar subtitle display + spike effect 7. Two lights on the right side of the bar display Working voltage: 7V-12V 100MA The level light has standard display mode and multiple automatic gain control (AGC) modes Wiring instructions: for LIN: left input SGND: signal input reference RIN: right input PGND: power supply +12V: 12V power supply positive pole Specifications: Parts name: level indicator Material: as shown Color: 7 green + 2 orange + 3 red Size: as shown Package content: A: 1*indicator + 1*wire B: 1*wire 1*circuit board 2*pin board
