Description :

The NJM2187 is a Passive Matrix TruSurroundTM 3D audio processor. It regenerates the full surround sound field directly from any kind of surround encoded stereo signal input. The internal passive matrix circuit decodes the surround encoded stereo signal, then the TruSurround Virtualizer encodes into two speaker virtual surround signal. Therefore no front processor which decode the surround encoded stereo signal to the 4 channel signals is required.

The NJM2187 also includes the SRS 3D-STEREO, and regenerates a 3D sound field from normal L/R input.

The NJM2187 is suitable for TV, mini component, CD radio cassette, multimedia speaker systems and others.
