Connect the sound box Connect the two wires at one end of the speaker wire to the audio output port of the power amplifier board. The left channel speaker is connected to the LOUT port of the power amplifier board, and the right channel speaker is connected to the ROUT port of the power amplifier board. The positive pole is connected to the + negative pole is connected to -. 2. Connect audio sources Using an audio cable with a 3.5mm stereo headphone plug on one end, plug into the 3.5 stereo headphone socket on the power amplifier board and connect the other end of the audio cable plug to the audio source (e.g. computer, mobile phone, MP3, DVD) 3. Connect the power supply ①. Connect the power adapter Use a power adapter with a DC output of 12V2A or above. Connect the output line to the 12V port of the power amplifier board with the positive terminal connected to the + port and the negative terminal connected to the - port.
(2) Connect the transformer
Use transformer with output AC 12V2A and above. Connect the two output wires of the transformer to the 12V port of the power amplifier board. Since the transformer outputs AC power, there is no positive or negative pole. 4. Play music Plug in the power supply, power amplifier board will enter the working state, blue light power indicator light; You can adjust the volume knob to your liking. Product details ①. The 2200uf filter capacitor is adopted in the power supply to provide abundant energy for the post-stage power amplifier, so that the sound of the power amplifier will not be soft in large dynamic conditions. The bass surging powerful, the middle is obviously beautiful, the treble clear and beautiful! ②.The BTL output circuit is composed of TDA7297 power amplifier integrated block of original ST, which has strong power! 6 "bookshelf speakers are effortless to push, sound warm and full, easy to retract, perfect for 2-6" small speakers and bookshelf speakers. 3-30W can be handled. ③. Blue LED power indicator, real-time monitoring of power supply status. ④.The audio input adopts 3.5mm universal stereo socket. Users can easily connect to mobile phones, computers, MP3s, ipads and other terminal devices as long as they use a double-ended 3.5 plug line. ⑤. Power input and audio output all use wiring block, as long as the screwdriver loosen the screw above, and then plug the wire into the wire, and then tighten the screw to complete the wiring, do not need a soldering iron can be easily completed.
