NJM2180
TruSurroundTM 3D AUDIO PROCESSOR
s GENERAL DESCRIPTION s PACKAGE OUTLINE TM *1) 3D audio processor. It regenerates The NJM2180 is a TruSurround full surround sound field from two speakers by the TruSurround Virtualizer *2) when either 5.1 channels by Dolby Digital or 4 channels by Dolby Pro *2) Logic signal is input. The NJM2180 also performs the SRS 3D-STEREO. In this mode, NJM2180 regenerates a 3D sound field from normal L/R input. In addition, the NJM2180 includes 2-type BYPASS mode THROUGH and MIX DOWN. In THRUOGH mode, the NJM2180 output 5.1 channels NJM2180L (max.) without any processing and in MIX DOWN mode, the NJM2180 output normal 2 channels stereo signal from 4 or 5.1 channels input The NJM2180 is suitable for TV, mini component, CD radio cassette, multimedia speaker systems and others.
For use in Virtual Dolby Surround(VDS) and/or Virtual Dolby Digital(VDD) products, please contact Dolby Laboratories for licensing information.
