AUDIO PROCESSOR
ꢀ GENERAL DESCRIPTION
ꢀ PACKAGE OUTLINE
The NJW1138 is an audio processor. It includes all of
functions processing audio signal for TV, such as tone
control, balance, volume, mute, NJRC original surround, and
AGC functions.
The NJRC original surround system reproduces natural
surround sound and clear vocal orientation.
All of internal status and variables are controlled by I2C
BUS interface.
