DATA SHEET Bipolar Analog Integrated Circuit µPC1892 MATRIX SURROUND SOUND PROCESSOR WITH SOUND PROCESSOR The µPC1892 is a specific IC to reproduce surround sound by using phase shifters and a signal matrix. The µPC1892 provides wide sound with two speakers, and rich stereophonic sound with three speakers. In case of stereo signal, the µPC1892 has the movie mode to reproduce sense of immediacy (for movie) and the music mode to emphasize vocal sound (for music), and it has the simulated mode to make monaural signal into wide deep sound. The modes can be selected freely by using 2-bit parallel control pins. In addition to this function reproducing surround sound, the µPC1892 has a general sound processor that has volume, balance, bass and treble control.
