DIGITAL SOUND CONTROLLER WITH SURROUND

DESCRIPTION

The M62492FP is an optimum digital sound controller IC for home audio.
It has a 5ch input selector,input trimmer,surround(3 variation),tone control(3 band) and master volume.
It can control all of these functions with serial data.
The IC is also available for Dolby Pro-logic Surround, because it has independent 4ch volume.
