3D AUDIO PROCESSOR

GENERAL DESCRIPTION
The NJM2181 is a Passive Matrix TruSurround
TM
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 re-
encodes 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.
