Overview
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA2041F Sound Field Reproduction IC The TA2041F is sound field reproduction IC developed for stereo audio equipment as radio cassette and music center.
This IC has made it possible to reproduce stereo phonic sound with more presence by forcing difference signals of R−ch and L−ch to delay and applying these signals to R−ch and L−ch again.
