1 First, connect the audio with the power amplifier. Only one wire is needed to connect the audio with the power amplifier. \x0d\2 Previous stereos were directly connected with bare wires, and then there was a knob behind the stereos. If you unscrew the knob, you will see a hole in the terminal, insert the wire and tighten the knob, that's all. In the past, almost all stereos were connected in this way, and there were other connectors, that is, specific plugs for specific stereos. This kind of plug is more humanized, just plug it in and rotate it. \x0d\\x0d\3 Then connect the power amplifier. In fact, the connection of the power amplifier is the same as the first audio. There is a hole at the terminal where the power amplifier is connected. Insert the thread and tighten the nut. It should be noted that there are many terminals behind the power amplifier, so you can't connect them randomly. A stereo connects two terminals, but it cannot be connected with the same color, horizontal connection or staggered connection. There are two terminals with different colors vertically. You should see red and black terminals. When wiring, just connect the two wires of each stereo to the terminals with different colors in the vertical direction. \x0d\\x0d\4 Next is the connection of the microphone, that is, the connection between the receiver and the power amplifier. All you need is a wire. Plug one end of the wire into the socket in front of the power amplifier and the other end into the socket of the receiver. Because the design of various power amplifiers and receivers are slightly different, if they don't work after being plugged in, you need to try another socket at this time. The microphone is now connected. \x0d\\x0d\5 The next step is to finally connect the media device. If you want your mobile phone, computer, mp3 player to play in stereo, you need a cable to solve these problems. Insert the part with two connectors, and insert two different colors vertically, with red facing red and white facing white. As for the other end of the line, you can find the plug into which the earphone is plugged, and then it is connected. Whether it is a mobile phone or a computer, you can play sound. After connecting the microphone, you can have a small KTV at home.
