AUDIO PROCESSOR
GENERAL DESCRIPTION The NJW1142A is a sound processor includes all of the functions required to process the audio signal for TV, such as tone control, balance, volume, mute, and AGC functions. Also the NJW1142A performs NJRC Surround "eala" which is regenerated 3D surround sound with only two speakers. 2 All of the internal status and variables are controlled by I C BUS interface. s PACKAGE OUTLINE
