AUDIO PROCESSOR with SOUND ENHANCEMENT
s GENERAL DESCRIPTION The NJW1137 is an audio processor with sound enhancement (BBE). It includes all of functions processing audio signal for TV, such as tone control, balance, volume, mute, NJRC original surround, and AGC functions. The NJRC original surround system reproduces natural surround sound and clear vocal orientation. The sound enhancement regenerates high definitive and nearly real sound. 2 All of internal status and variables are controlled by I C BUS interface. s PACKAGE OUTLINE
