NJW1199
8-CHANNEL ELECTRONIC VOLUME WITH INPUT SELECTOR
■ GENERAL DESCRIPTION
The NJW1199 is a 8-channel electronic volume with
Input Selector. It includes 13-in 4-out stereo audio
selector , REC Output and Multi-channel inputs.
The NJW1199 performs low noise and low distortion
characteristics with resistance ladder circuit.
All of functions are controlled via three-wired serial bus.
Selectable 2-Chip address is available for using two chips
on same serial bus line.
The NJW1199 is suitable for multi-channel audio system,
such as AV amplifier, DVD receiver, and others.
