The device that separates the audio signal is located in front of the power amplifier. After frequency division, the independent power amplifier is used to amplify the signals of each audio frequency band and then send them to the corresponding speaker units. A low-power electronic active filter is realized, the adjustment is simpler, and the power loss is small and reduced. Package includes: 1*Audio processor
