NJW1176
AUDIO PROCESSOR with Subwoofer Output
s GENERAL DESCRIPTION The NJW1176 is a sound processor with subwoofer output includes all of functions processing audio signal for TV, such as tone control, balance, volume, mute, and AGC functions. Also the NJW1176 includes the LPF for subwoofer output and bass boost function. The original surround system reproduces natural surround sound and clear vocal orientation. 2 All of internal status and variables are controlled by I C BUS interface. s PACKAGE OUTLINE
