NJW1169
AUDIO PROCESSOR with BBE Sound Enhancement & Passive Matrix TruSurround Virtualizer & TruBass
s GENERAL DESCRIPTION The NJW1169 is an audio processor with Passive Matrix TruSurround Virtualizer, TruBass and BBE sound enhancement. It includes all of functions processing audio signal for TV, such as volume, balance, tone control, "eala" NJRC Surround, simulated stereo, mute function, line out and AGC function. 2 All of internal status and variables are controlled by I C BUS. It is suitable for any TV set. s PACKAGE OUTLINE
