1. If the lamp has PWM dimming interface: MIC picks up sound signal → amplification → half-wave rectification → voltage frequency V/F conversion circuit →PWM dimming interface.

2. If the lamps do not have PWM dimming interface, but contain constant current circuit, it is necessary to remove the constant current circuit inside each lamp and add an adjustable constant current source. MIC picks up sound signals → amplification → voltage-frequency V/F conversion circuit →PWM dimming drives all LED lamps.

I hope it helps you.
