NJW1175
AUDIO PROCESSOR with BBE ViVA+
s GENERAL DESCRIPTION
The NJW1175 is a TV audio processor with BBE ViVA+
High Definition 3D Sound process. BBE's traditional sound
clarity enhancement technology is combined with the
Mach3BASS process to bass enhancement and the new
ViVA 3D process to create an authentic and exciting spatial
effect.
The NJW1175 contains all necessary functions to process
TV audio signal such as volume control, tone control,
balance, mute and AGC function.
