M62492FP
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.
FEATURES
Built-in 5ch input selector Built-in input volume Built-in Surround(ON / OFF,High / Middle / Low(3 variation)) Electric volume(A and B volume) Volume level ---- 0dB to -79dB,dB(1dB / step) Tone control Bass / Mid / Treble,0dB to 10dB(2dB / step) Bass boost +10dB(ON / OFF) 3 Output ports Built-in microcomputer interface controlled by 16-bit serial data.
