DIGITAL ECHO DIGITAL DELAY

The M65831A is an IC developed for producing echo effects added to voice signals picked up by microphone for karaoke applications. The IC has the largest memory among the digital delay series. As it’s design is aimed at high performance, it is best suited to provide radio cassette tape recorders and miniature unit audio system with quality echo function. Being pin compatible with the M65830CP / FP and M65843AP / FP, the M65831AP / FP is suitable for upgrading the series.
