描述 Description

■ GENERAL DESCRIPTION
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. Accordingly any pre-processors decoding into 4 channel signals are not required.
The NJM2181 also includes SRS 3D Stereo and 3D Mono, and regenerates a 3D sound field from either normal L/R input or monoural input.
The NJM2181 is suitable for TV, mini component, CD radio cassette, multimedia speaker system, and others.■ FEATURES
