LED Light Audio Level Indicator The minimum volume module PCB size is 80x14 mm, with the LED module area measuring 58x14 mm. Multiple Functions and Adjustable Speed Users can adjust the realtime speed of each light bar and the main light, enabling multiple operating modes and custom visual feedback. TI Signal Isolation for Audio Input The audio input uses TI signal isolation to effectively prevent frequency interference caused by MCUseries connections to the audio circuit. Current Limiting Resistors for Different Colors Lights of different colors are equipped with dedicated currentlimiting resistors for performance. The module uses 7 green, 2 orange, and 3 red LEDs. Visual Effects and Display Modes The indicator can display the peak zone and position after the signal peak, provide a strip display after the peak disappears, offer a bar display with no peak, and support additional display options. Working Voltage and Color Operating voltage range: 712 V. Current capacity: above 100 mA. Color configuration: 7 green, 2 orange, and 3 red. Applications Car audio system calibration and peak monitoring during installation or tuning. DIY speaker projects, amplifiers, or multimedia panels that require realtime audio level visualization. Recording studios or live sound setups for quick visual feedback on signal levels and peak activity.
