This RGB LED Color Organ HK9820 is a fully assembled 3-channel spectrum analyzer designed to create dynamic visual effects using an RGB 5050 LED strip. The device uses an electret microphone and dedicated filters for low, mid and high frequencies, each controlling one of the three LED colors. With adjustable sensitivity and trimmer controls for each frequency band, this module provides a vibrant real-time music visualization experience. Suitable for DIY projects, home audio effects, stage lighting accents and creative installations.
