Stereo degree of separation is the degree of information isolation between channels in a system, usually expressed in terms of crosstalk and channel isolation. Stereo resolution is conventionally expressed by the difference between the signal level of one channel in two-channel stereo and the level of the signal leaking to the other channel and the level of the main signal. In theory, if the left channel speaker is disconnected, there will be a weak sound when listening carefully. This is the right channel sound signal leaking to the left channel via power, common ground or other means. The larger the difference is, the greater the stereo separation and the better the separation. The solution is to use two independent power supplies with two independent power supplies. The ground wire and other facilities are also independent of each other, or two single-channel power amplifiers of the same model can be used to separately amplify the left and right channel signals to completely reduce the channel. Mutual interference and crosstalk occur.
