NJW1149
Audio Processor with Sound Enhancement and TruSurround 5.1ch Virtualizer
■ GENERAL DESCRIPTION
The NJW1149 is an audio processor with BBE sound enhancement
and SRS Labs' TruSurround 5.1 channel virtualizer. It includes all of
functions processing audio signal for TV, such as volume, balance, mute,
tone control, eala NJRC original surround and simulated stereo
2
functions. All of internal status and variables are controlled by I C BUS.
