The NJM2181 is a Passive Matrix TruSurroundTM 3D audio processor. It regenerates the full surround soundfield directly from any kinds of surround encoded stereo input (Lt/Rt) signals. After the internal passive matrix circuit decodes Lt/Rt signal into 4 channel signals, the TruSurround virtualizer reencodes them into 2 channel surround signals.
