Fule Stereo Music Spectrum LED Light Audio Level Indicator VU Meter 12V 24V

feature: 1. Minimum 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 main light. 3. The audio input adopts the original TI signal isolation to avoid the high frequency interference caused by the MCU series connection to the audio circuit to the greatest extent. 4. Lights of different colors provide current limiting resistors. important hint: 1 During the sampling time the single-chip microcomputer makes the dual-channel parallel input signal change rapidly and the amplitudes displayed by the two light bars may be different which is a normal situation. 2. In extreme cases very slight high frequency noise may be present. It is recommended to change the position of the signal input cable to a two-core shielded cable. 3. Working voltage: 7-12V current can work above 100MA. Levels of photodamage will result if you disable or reverse the positive and negative poles for voltages higher than 12V visual effect: 1. Display the zone + location after the peak of the trip 2. Strip display + after the stroke peak disappears 3. Bar display + (no peak display) 4. After the maximum disappears right click to display + 5. Bar display + (three lights) 6. Striped subtitle display + spike effect 7. Pick + jump lights on the right side of the bar display light up two Working voltage: 7V-12V 100MA Color: 7 green + 2 orange + 3 red Liquid level lamps have standard display modes and various automatic gain control (AGC) modes Wiring Instructions: LIN: left input SGND: Signal input reference RIN: right of entry PGND: Power +12V: 12V power supply positive Note: The power supply must be within the range of 7-12V DC power supply and the current is greater than 100MA (do not use surge and the power cord should not be reversed). Package includes: 1*Indicator 1*line
