This professional power control module is specially designed for audio amplifier power management and noise suppression. It adopts a low-current momentary switch to control high-current power output, which effectively avoids button burnout caused by direct large-current switching. Users can connect a common small signal button to achieve stable power ON/OFF control for high-power amplifier circuits.
Equipped with a soft-start function, the board slowly raises the input current during power-up, significantly suppressing inrush current and protecting power supplies, amplifier chips and speaker units from instantaneous current impact. Especially when powered with batteries, The inrush starting current will trigger the protection circuit and cut off the battery output. You can use this board solve this problem.
With a dedicated MUTE control pin, it automatically enables mute mode during power-on and power-off processes, thoroughly eliminating POP noise and transient shock sound to deliver clean and quiet audio switching. The board reserves an indicator interface for external LED lights to display real-time power status clearly and intuitively. Compact and highly practical, this module is widely compatible with AB-class, D-class power amplifiers, active speakers, and all kinds of audio power amplifier systems.
RGB LED port: We only use green LED on this version.
