【Mini Powerful】 This subwoofer audio amplifier board outputs 100W+100W power, features Bluetooth 5.0 wireless connectivity, Bluetooth + AUX audio input, and 2.0 dual-channel stereo output. It includes a built-in low-noise amplifier and shielding interference for excellent sound quality. Compatible power supply: DC12~24V/5A or above, compatible speakers: 20~200W/4~8Ω. Note: The audio amplifier board kit requires self-assembly.
【Treble and Bass Control】 Equipped with independent treble and bass adjustment knobs, allowing direct adjustment of treble and bass through the module without using a player or speaker. This is perfect for DIY devices that are low in volume or cannot adjust treble and bass. If you're tired of fixed treble and bass levels, why not try the treble and bass control knobs!
【Hi-Fi】 The audio power amplifier board uses the TPA3116D2 chip and has AM interference suppression capabilities, with a signal-to-noise ratio of >90 dB. It features a built-in shielded power inductor and low-noise front-end op-amp for superior sound quality. The left and right dual-channel stereo output lets you enjoy high-quality audio experiences.
【Safety Protection】 This Bluetooth amplifier module is designed with over-voltage, under-voltage, over-temperature, DC detection, and short-circuit protection to ensure safe and stable operation. The module comes with a heat sink, preventing overheating during continuous output.
【BT and AUX Input】 Supports both AUX input and Bluetooth 5.0 as input methods for convenient connections with various devices. Bluetooth 5.0 offers longer wireless transmission distances, reaching up to 32 feet (about 10 meters) in open environments. It's compact and portable, easy to set up—ideal for DIY speaker players. Note: When using AUX mode, please ensure that the Bluetooth connection of this module is disconnected.
