NJRC NJW1140

NJW1140
PRELIMINARY
AUDIO PROCESSOR with SRS
■ GENERAL DESCRIPTION
The NJW1140 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 NJW1140 performs SRS 3D Stereo which
regenerates 3D surround sound with only two speakers.
All of the internal status and variables are controlled by
2
I C 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.
•”CHS” : Defines the channel should be attenuated
