Low-Voltage 2-channel Electronic Volume with ealaBASS

!GENERAL DESCRIPTION

!PACKAGE OUTLINE

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.

NJW1200V

All of internal status and variables are controlled by I²C

BUS interface.
