1. First of all, check whether the audio cable behind the amplifier and stereo is complete. If not, you must first buy a section from the hardware store. It need not be too long, otherwise it will be put on the back.

2. It is easy to connect the audio cable. First, find a pair of vise or scissors, and strip the audio cable thread out of the rubber layer on the outer surface to expose the copper wire inside. Generally, it is two colors: brass and silver.

3. After the audio cable is peeled off, twist the copper wire a few times by hand to make the copper wire harder. Then you can see that there are red and black terminals behind the power amplifier, the brass-colored one is connected to the red column, and the silver one is connected to the black column.

4. The other end of the audio cable is also connected to the back of the stereo. Some of the stereo is of terminal type, while others are more convenient and snap-in type. Press down the buckle with your fingers, poke the thread in, and then let go, the thread is clamped by the buckle, which is very simple.

5. If there are two stereos, connect the lines to Left and Right respectively, that is, one line to the left and one line to the right.

6. After the power amplifier and the audio are connected, the sound source must be input to the power amplifier. The sound source can be used in a DVD player in general. If allowed, a notebook can also be used, which is more flexible. The connection line needs to use two audio lines with lotus heads at both ends. The L and R channels inserted under OUTPUT at the back of DVD output sound signals, and the power amplifier is also inserted under L and R, but note that it is under INPUT input. In this way, the sound will be output from the DVD to the power amplifier, and then from the power amplifier to the sound.

7. Finally, you can turn on the DVD and power amplifier for testing. As long as the lines are not connected incorrectly, you can hear the sound.

The debugging work of sound engineering needs to be treated with a serious and responsible attitude. Only after ensuring that the design, construction, system structure and stage sound equipment performance are fully understood can a better debugging result be obtained. For the problems that often occur in general debugging work, here we introduce some technical links that should be paid attention to during debugging for your reference.
