NJRC NJW1167

NJW1167/A
AUDIO PROCESSOR with Subwoofer Output
■ GENERAL DESCRIPTION
The NJW1167/A 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 NJW1167/A 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.

LPF Block Diagram
The NJW1167 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.
<Primary LPF>
f c1 =

=
2π * R * C1 2π * 24 *10 3 * C1
Q1 = 0.5

•VOL Attenuation level : 0 to –80dB(0.33dB/step) , MUTE
The attenuator is consisted of both the VOL1(0.165dB/step)and VOL2(0.165dB/step) and is enable to adjust 0.33dB/step.
The attenuation for both the VOL1and VOL2 are always synchronized to have the same attenuation levels for each other,
and are not controllable independently for each other.
ex) VOL(-30dB) = VOL1(-15dB) + VOL2(-15dB)
