NJW1186
5.1ch Surround Processor
s
GENERAL DESCRIPTION
The
NJW1186
is an Surround Processor for 5.1ch speaker
system regenarating Center, Surround and Subwoofer channel
signal from normal stereo signal input. The
NJW1186
contains
Passive Matrix circuit, BPF for center channel, LPF for subwoofer,
simulated stereo function for surround channel and trimmers for
each channel.
2
All of internal status and variables are controlled by I C BUS.
It is suitable for TV set, Home Theater and the others.
