NJW1149A
Audio Processor with Sound Enhancement and TruSurround 5.1ch Virtualizer
s GENERAL DESCRIPTION The NJW1149A 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 surround and simulated stereo functions. All of 2 internal status and variables are controlled by I C BUS. The NJW1149 is available for Virtual Dolby Surround or Virtual Dolby Digital with Dolby Pro Logic or Dolby Digital system*. *For use in Virtual Dolby Surround(VDS) and/or Virtual Dolby Digital(VDD) products, please contact Dolby Laboratories for licensing information. Dolby and the double-D symbol are trademarks of Dolby Laboratories Licensing Corporation. Licensing and application information may be obtained from Dolby Lab. s PACKAGE OUTLINE
