PROBLEM TO BE SOLVED: To prevent a D-A converter from being wasted. SOLUTION: In the sound signal reproducer where a digital sound signal of n (n is 2, 6 or 8) channel is fed to a bus management function circuit 1 producing a digital sound signal of (n+1) channel including a low frequency sound signal, the low frequency sound signal from the bus management function circuit 1 is fed to a woofer not through a D-A converter but through a low-pass filter 21. |
