AUDIO PROCESSOR with SOUND ENHANCEMENT
■ GENERAL DESCRIPTION
■ PACKAGE OUTLINE
The NJW1137 is an audio processor with sound
enhancement (BBE). 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.
The sound enhancement regenerates high definitive and
nearly real sound.
All of internal status and variables are controlled by I2C
BUS interface.
