NJW1160

P R E L I M I N ALY NJW1160 AUDIO PROCESSOR with SOUND ENHANCEMENT and SRS 3D STEREO www.datasheet4u.com I GENERAL DESCRIPTION The NJW1160 is an audio processor that includes Sound enhancement (BBE) and SRS 3D Stereo. It includes all of the audio signal processing functions for TV such as tone control, balance, volume, mute, and AGC . The SRS 3D stereo technology reproduces 3D stereo surround sound effect using only two speakers. The sound enhancement regenerates high definitive and nearly real sound. 2 All of internal status and variables are controlled by I C BUS interface.
