NJW1200
Low-Voltage 2-channel Electronic Volume with ealaBASS
!GENERAL DESCRIPTION
The NJW1200 is a low-voltage 2-channel Electronic
Volume with ealaBASS. It includes main volume, 2 stereo
inputs selector (Differential Input), 2nd Order HPF. And It
performs NJRC original dynamic bass boost technology
“ealaBASS” provides graceful bass sound with low
distortion.
The NJW1200 performs low noise and low distortion
characteristics with resistance ladder type electrical volume.
The NJW1200 operates on low supply voltage. And It
includes power save function. Therefore, it is suitable for low
voltage supply portable systems.
All of internal status and variables are controlled by I2C
BUS interface.
