Abstract (en)
[origin: EP1003282A2] An integrated circuit for processing an audio signal includes a circuit for processing an input audio signal to create a front output signal, rear output signal and a sub-woofer output signal which are to be outputted to a front speaker, a rear speaker and a sub-woofer; and a switch for selecting the rear output signal or the sub-woofer output signal. The output from said switch is connected to a common output to the front speaker and the sub-woofer. In this configuration, the number of input/output terminals can be reduced.
