A DVD audio signal reproducer 132-2 reproduces a DVD to generate a DVD reproduced audio signal S5.1c, S2c. A reproduced signal determiner 134 determines whether the DVD reproduced audio signal is a 5.1-channel digital surround audio signal or a 2-channel digital audio signal, thereby generating a determination signal SW. If the determination signal SW indicates that the DVD reproduced audio signal S5.1c, S2c is a 5.1-channel digital surround audio signal S5.1c, a digital surround effector 160 converts the DVD reproduced audio signal S5.1c to a 2-channel digital surround audio signal S2cd.
