Stereo Audio Level Indicator VU Meter LED Light with Adjustable Speed and Multiple Display Modes for 12V 24V Systems Featuring Signal Isolation (A)

Product description feature:1. Minimum volume, PCB size 80*14mm LED module area: 58*14mm2. With multiple functions, users can freely adjust the actual speed of each light bar and main light.3. The audio input adopts the 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 12Vvisual effect:1.
