What line is suitable for the 40w outdoor sound column and the audio output port of the surveillance camera?
2. Then I connected the white cable to the original connector, which had a heavy bass-it's normal for you to ground him-because the input was only one channel. This is very dangerous, the last stage of your sound card may be burned-because you connected the signal output to the output of the amplifier (if the power supply voltage of the amplifier is high). The correct method should be: connect one end of a copper wire to the metal shell of the computer case or the exposed section of the 3.5 plug-that is, connect him with a ground wire, and connect the other end to the outer metal ring of the lotus socket of the power amplifier (any of the four sockets).
I suggest that you don't connect the computer with this substandard signal line. Due to the uncertainty of access point, unexpected short circuit may occur. Although the sound card output has capacitor isolation DC, the risk is still great. Burn the sound card if it is not good.
