PRELI M I N ARY Passive Matrix TruSurroundTM 3D Audio Processor sGENERAL DESCRIPTION TM The NJM2188 is a Passive Matrix TruSurround 3D audio processor. It regenerates the full surround sound field 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 encodes them into 2 channel surround signals again. Accordingly any pre-processors decoding into 4 channel signals are not required. The NJM2188 also includes the SRS 3D-STEREO, and regenerates a 3D sound field from normal L/R input. The NJM2188 is suitable for TV, mini ponent, CD radio cassette,...
