摘要： PROBLEM TO BE SOLVED: To solve a problem of a conventional acoustic reproducing device that is provided with digital/analog converters whose number is equal to number of channels although an output signal of a low frequency channel has not almost be used. SOLUTION: In the signal processing unit of this invention, a decoder 6 separates a digital audio signal of a multi-channel of 5.1 ch from an audio bit stream signal 40 and a down mix signal processing means 3 employs down mix processing to convert the digital audio signal of 5.1 ch into a digital audio signal of 2.1 ch. Adders 7a, 7b add the digital audio signal of a low frequency channel to L and R channel digital audio signals to provide an output of a sum signal. Digital/analog converters 61, 62 convert the sum signal into an analog audio signal. A signal processing means 2' eliminates a low frequency component from the analog audio signal and provides an output of the result. A signal processing means 1 extracts the low frequency component from the analog audio signal added by an adder 7c and provides an output of the result.
