NJW1168
AUDIO PROCESSOR with Input Selector and Subwoofer Output
s GENERAL DESCRIPTION The NJW1168 is a sound processor with subwoofer output includes all of functions processing audio signal for TV, such as input selector, tone control, balance, volume, mute, and AGC functions. Also the NJW1168 includes the LPF for subwoofer output and bass boost function. The eala reproduces a natural surround sound with clear vocal orientation. And also, voice enhancement gives clear sound such as dialogs. 2 All of internal status and variables are controlled by I C BUS interface. s PACKAGE OUTLINE
