Bass Treble Bluetooth Amplifier-50W+100W

Experience cinematic-quality audio at home with our Bluetooth Amplifier featuring bass and treble control. Equipped with three output channels, it deftly minimizes AM interference and filtering to maintain total harmonic distortion (THD) as low as 0.1%, even during extended high-power usage, delivering consistently clear and rich sound.

The amplifier is powered by a DC12~24V power supply and supports both AUX and Bluetooth 5.0 audio inputs. With a robust 50W output for left and right channels and an impressive 100W output for subwoofer channels, it is engineered to elevate your sound experience. Its five adjustable knobs allow seamless control over power, main volume, bass, treble, subwoofer frequency, and volume, optimizing your listening experience.

Designed to be versatile, this amplifier is compatible with 4-8Ω, 20W-100W passive speakers. It connects effortlessly with devices like Raspberry Pi and smartphones, allowing Bluetooth interaction for DIY projects. The board is equipped with protective bottom and top panels, ensuring safety with features like over-voltage, under-voltage, overheating, short-circuit, and DC detection protection.

Start by connecting the amplifier to a speaker and powering it on. When the main volume knob is rotated, an indicator LED will light up. Activate your phone's or Raspberry Pi’s Bluetooth, locate "BT-WUZHI," and connect. Upon successful connection, indicated by a "ding-dong," music playback is ready. Future connections are automatic upon powering the module.

For optimal performance, ensure sufficient audio input and power source voltage/current as these factors directly influence power output. Additionally, be aware that greater speaker impedance results in reduced output power. While adjusting treble and bass, if distortion occurs with rightward adjustment, reduce gain by turning the knobs left or decrease the overall volume with the main volume knob.
