HIFI Digital Bluetooth Amplifier-50W*2

The HIFI Bluetooth Power Amplifier board brings superior sound quality through advanced technology. It offers features like AM interference suppression and a filtering function, delivering a total harmonic distortion (THD) as low as 0.1%, even under long-term, high-power operation. The result is a rounded and clear audio experience. With a robust output power of 50W, volume adjustment knob, and dual-channel output, it provides versatility in sound management through AUX and Bluetooth 5.0 inputs.

This device operates within a DC voltage range of 5-27V and is compatible with 4 to 8-ohm passive speakers rated between 30W and 200W. Pair it seamlessly with a Raspberry Pi, mobile phones, or other Bluetooth-enabled main controllers to elevate any audio project. Imagine connecting it to a setup of your choice, and effortlessly transforming ordinary sound into extraordinary experiences.

Constructed with both top and bottom protective panels, the board is equipped with several protection measures. Safeguards include overvoltage, undervoltage, overheating, short circuit protection, and DC detection, ensuring reliability and durability under varying conditions. Its intuitive operation makes it easy to connect—just link your speaker, power it up, and enjoy instant sound once "BT-WUZHI" appears for Bluetooth connectivity.

To maximize performance, ensure that the amplifier board's audio input and power source voltage and current are sufficient. Note that higher power supply voltage translates to greater output power. Additionally, keep in mind that while using it, the speaker impedance can impact output power—a balance between voltage, current, and speaker impedance is essential for optimal sound production.
