UPC1892 MATRIX SURROUND SOUND PROCESSOR WITH SOUND PROCESSOR

Capacitor connection pin which determines time constant of phase shifter. Pin 2 is used for movie, music, simulated mode. Pins 2, 3, 4, 5 is used for movie, simulated mode. Recommended value of capacitor is as follows. Pin 2: 0.1 µF Pin 3: 2200 pF Pin 4, 5: 0.022 µF 3 kΩ 2 6 Offset filter VCC 50.

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 t.
