NJRC NJW1176 Audio processor with subwoofer output Datasheet

NJW1176
AUDIO PROCESSOR with Subwoofer Output
■ GENERAL DESCRIPTION
The NJW1176 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 NJW1176 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.

•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)
