After the power amplifier is connected to the audio, it is necessary to input the audio source to the power amplifier. Generally, DVD players can be used as audio sources, and notebooks can also be used if allowed, which is more flexible. Connecting cables requires two audio cables with shower heads at both ends. The L and R channel output sound signals inserted behind the DVD are also inserted in the L and R channels of the power amplifier, but pay attention to the input. In this way, the sound will be output from DVD to power amplifier, and then from power amplifier to audio.
