s GENERAL DESCRIPTION
The NJW1164 is a TV audio processor with sound
enhancement (BBE).
The NJW1164 contains all necessary functions to process
TV audio signal such as volume control, tone control,
balance, mute, AGC and NJRC's proprietary surround sound
process, eala. The eala reproduces a natural surround
sound with clear vocal orientation.
The total modes and variables are controlled by the I2C bus
interface.
