Bass Treble Bluetooth Amplifier-50W*2

This powerful Bluetooth Amplifier is engineered with independent bass and treble tone controls, providing an audio experience that maintains a low Total Harmonic Distortion of 0.1%, even under prolonged high-power usage. It utilizes an AM interference and filtering function to deliver clear and rounded sound. With a DC9-24V power supply and AUX+Bluetooth 5.0 audio input, it boasts a robust 50W output power, making it compatible with 4-8Ω, 15W-100W passive speakers. The board's user-friendly design features three adjustable knobs for powering on/off and controlling the main volume, bass, and treble.

Connecting your Bluetooth Amplifier is seamless. Simply pair it with your choice of device—be it a Raspberry Pi or mobile phone—and enjoy wireless streaming for your DIY projects. The board comes equipped with bottom/top protective panels and an array of safeguard mechanisms, including over-voltage, under-voltage, overheating, and short-circuit protection, along with DC detection, ensuring reliable performance.

Operational use is intuitive: connect the board with a speaker, power it on, and use the main volume knob to initialize the device, indicated by an LED light. Once powered, activate Bluetooth on your chosen device to locate “BT-WUZHI” and connect with ease. Subsequent connections occur automatically post initial setup, marked by a distinct ding-dong tone.

Note that maximum performance is achieved with adequate audio input and power source voltage/current. High power supply voltage results in improved output power, but speaker impedance plays a critical role in the amplifier's output capabilities. Adjust bass and treble settings carefully to avoid distorted sound, keeping the volume balanced by tweaking the knobs accordingly.
