Description :

The NJM2188 is a Passive Matrix TruSurroundTM 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 component, CD radio cassette, multimedia speaker system ,and others.
