AUDIO PROCESSOR
■ GENERAL DESCRIPTION
■ PACKAGE OUTLINE
The NJW1144 is a sound processor includes all of the
functions required to process the audio signal for TV, such
as tone control, balance, volume, mute, and AGC functions.
Also the NJW1144 performs BBE sound enhancement
and SRS 3D Stereo. The BBE regenerates high definitive
and nearly real sound, and SRS 3D Stereo regenerates 3D
surround sound with only two speakers.
All of the internal status and variables are controlled by
I2C BUS interface.

VOL
The attenuator is consisted of both the Volume1 and Volume2. The total attenuation level is summing of each
attenuation level of the Volume1 and Volume2. The attenuation for both the Volume1 and Volume2 are always
synchronized to have the same attenuation levels for each other, and are not controllable independently for each
other.
•”VOL”: Sets the total attenuation level for the both Ach and Bch (up to 84dB, 0.33dB/step)

■Channel Balance Control
To control the balance between Ach and Bch, the both commands “CHS” and “BAL” should be set. For example,
to move a sound image to Ach-side, Bch should be attenuated with no attenuation on Ach. The command “CHS”
defines the channel should be attenuate, and the command “BAL” defines the attenuation level itself. The
attenuation for the balance control is consisted of the both Volume1 and Volume2, has the same structure with
Master Volume Control described above.
