Abstract
An audio signal processing device, including: a digital signal processing module, an input module, an output module, and a control module. The digital signal processing module is in connection with the input module and the output module, and the control module is in connection with the output module. The output module includes at least two output channels, with each output channel including a power amplifier and a speaker in series connection. The digital signal processing module is configured to receive an audio signal output by the input module and to process the audio signal with at least two different audio processing algorithms, and output the at least two audio processing signals. Each audio processing signal corresponds to one output channel. The control module is configured to control the operation state of the power amplifier of each output channel and the magnification thereof in operation.
