PACKAGE OUTLINE
The
NJW1140
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
NJW1140
performs SRS 3D Stereo which
regenerates 3D surround sound with only two speakers.
All of the internal status and variables are controlled by
I
2
C BUS interface.
