NJW1147A
AUDIO PROCESSOR with BBE ViVA
s GENERAL DESCRIPTION
The NJW1147A is a TV audio processor with BBE ViVA
High Definition 3D Sound process. BBE's traditional sound
clarity enhancement technology is combined with the new
ViVA 3D process to create an authentic and exciting spatial
effect. BBE ViVA is compatible with news, music and
movie programs as well as video games.
The NJW1147A contains all necessary functions to
process TV audio signal such as volume control, tone
control, balance, mute, AGC and NJRC's proprietary
surround sound process, eala. The eala reproduces a
natural surround sound with clear vocal orientation.
The total modes and variables are controlled by the I2C bus
interface.
