NJRC NJW1166L

NJW1166
AUDIO PROCESSOR with Subwoofer Output
■ GENERAL DESCRIPTION
The NJW1166 is a sound processor with subwoofer
output includes all of functions processing audio signal for
TV, such as tone control, balance, volume, mute, and AGC
functions.
Also the NJW1166 includes the LPF for subwoofer output
and bass boost function.
The original surround system reproduces natural surround
sound and clear vocal orientation.
2
All of internal status and variables are controlled by I C
BUS interface.

The NJW1166 includes the LPF for subwoofer output and bass boost function. The LPF consists of primary and
secondary LPF and it is enable to adjust “cut off frequency”, “Q” and “Roll off”.
The expression of LPF characteristics is as follows.
