See as the figure, both the output and input are dual-channel, by the switch on 13-pin, we can choose normal sound or surrounded sound. After crossing the buffer, the input R and L signal is split into the main signal and vice signal. The vice signal is sent to the low-pass filter LPFI by R-L, then it shifts the phase, and then it crosses the low-pass filter LPF2 and is added with the main signal by the switch. The R channel signal is to do the same phase addition, so that the signal that we get is sent out by the low-pass filter LPF3 and the buffer.
