Product Details
Do you care about sound quality? If so, check out this amazing HIFI Bluetooth power amplifier board! It comes with AM interference suppression and filtering capabilities. Even when operating at high power for extended periods, the Total Harmonic Distortion (THD) can be as low as 0.1%, delivering incredibly smooth and clear sound. With an output power of 100W, a volume adjustment knob, AUX + Bluetooth 5.0 input, dual - channel output, and a DC 5 - 27V operating voltage, this amplifier board is a great choice. It works perfectly with 4 - 8Ω, 50W - 300W passive speakers. Connect it to Raspberry Pi, mobile phones, or other Bluetooth - enabled main - controllers to start your DIY projects. The board features 5 high - quality 470uf capacitors for stable output, a heat sink, and an excellent power module. It also has bottom/top protective panels and supports multiple protection mechanisms such as overvoltage, undervoltage, overheating, short - circuit protection, and DC detection. Specifications include a 5 - 27V power supply, AUX + Bluetooth 5.0 input, HIFI audio quality, 100W * 2 output power, compatibility with 50W - 300W, 4Ω - 8Ω speakers, left/right stereo channels, a 15m Bluetooth transmission distance (without obstacles), and various protection mechanisms. Shipping includes one HIFI Digital Bluetooth Amplifier - 100W * 2, two acrylic protective cases, one screwdriver, one 20cm power wire, one knob, one heat sink, and one accessories package.
Using this amplifier is easy. First, connect the board to a speaker and power it on. Then rotate the knob, and the indicator LED will light up. Turn on the Bluetooth on your phone or Raspberry Pi, search for 'BT - WUZHI', and click to connect. You'll hear a prompt tone when the connection is successful, and you can start playing music. The Bluetooth will reconnect automatically next time the module is powered on. Note that for the board to output enough power, both the audio input and the power source voltage/current need to be sufficient. The higher the power supply voltage, the larger the output power. Also, speaker impedance affects the amplifier board's power output. With enough voltage and current, a higher speaker impedance means a lower output power. As for maintenance, keep the amplifier in a dry and cool place. Check the protective panels regularly to make sure they are in good condition. If the heat sink gets dirty, clean it gently with a soft brush.
