Digital Bluetooth Amplifier 2x50W+100W Subwoofer

With the Bass Treble Bluetooth Amplifier, you can enjoy a home cinema-like sound experience in your home. This powerful Bluetooth amplifier offers three output channels and features an AM interference and filter function, which ensures low distortion even at high power. Equipped with a DC12-24V connection, it offers both AUX and Bluetooth 5.0 inputs. The left and right channels each deliver 50W, while the subwoofer channel provides up to 100W of power. With five adjustable knobs, you can control the main volume, bass and treble, as well as the subwoofer frequency and volume. The amplifier is compatible with 4-8Ω, 20W-100W passive speakers and can be easily connected to the Raspberry Pi, mobile phones, and other Bluetooth devices. 

Note: The board only provides sufficient power if the audio input voltage and supply voltage are sufficient. The higher the supply voltage, the greater the output power. Also, the speaker resistance changes the output power of the amplifier board. Please note that with sufficient voltage and current, the resistance of the speaker in ohms reduces the output power, the higher it is. When adjusting treble and bass sound: If the TRBLE or BASS tones are turned almost to maximum and the sound is distorted, this means the gain of the treble/bass tones is too high. In this case, turn the TRBLE or BASS knob to the left to decrease the gain, or turn the MAIN VOLUME knob on the right to reduce the overall volume.
