It includes four independent 8-input-1output stereo audio selectors
and 0dB fixed gain buffers.
The NJW1112 performs superior audio characteristics such as low
distortion, low output noise and low crosstalk.
In addition, the NJW1112 is available to expand to 16-input
4-output stereo audio selector without sound quality deterioration,
because it is able to connect in parallel by Output switch function.
All of internal status and variables are controlled by three-wired
