NJW1190
AUDIO PROCESSOR with Multipurpose Surround Sound System
and Input Selector
s GENERAL DESCRIPTION
The NJW1190 is a sound processor with Multipurpose
Surround Sound system includes all of functions processing
audio signal for Mini-Component and TV, such as input
selector, tone control, balance, volume, and mute functions.
Also the NJW1190 includes the 5 types of surround
sound and Bass Boost function. Their combination
reproduces a number of sound effects.
NJW1190 performs low noise and low distortion
characteristics with resistance ladder type electrical volume.
All of internal status and variables are controlled by I2C
BUS interface.
