SRS 3D SURROUND AUDIO PROCESSOR
■GENERAL DESCRIPTION
■PACKAGE OUTLINE
The NJM2198 is a SRS 3D surround audio
processor regenerating the 3D surround sound with
only two speakers.
It regenerates 3D surround sound from both of
monaural and stereo input.
The features of wide operating voltage range, wide
dynamic range, low output noise are suitable for any
audio applications.
