PC1892
MATRIX SURROUND SOUND PROCESSOR WITH SOUND PROCESSOR
The PC1892 is a specific IC to reproduce surround sound by using phase shifters and a signal matrix. The PC1892 provides wide sound with two speakers, and rich stereophonic sound with three speakers. In case of stereo signal, the PC1892 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 PC1892 has a general sound processor that has volume, balance, bass and treble control. So it is capable of reducing installation area. All functions for processing signals of base band sound are provided on one chip.
FEATURES
* * * * * Three surround modes are available: movie, music and simulated Built in volume and balance control (All control voltage: 0 V to 5 V) Built in tone control (bass, treble) (All control voltage: 0 V to 5 V) Built in L+R output for woofer SP PC1892CT-02: The volume and balance attenuation are bigger than PC1892CT.

MODE SELECT CODE
Select among OFF, Movie, Music and Simulated mode by MS1 and MS2 (Pins 7 and 8).
Code Mode OFF Music Movie Simulated MS1 (Pin 7) L H L H MS2 (Pin 8) L L H H
Cautions 1. In the case of changing surround mode and power ON/OFF, mute (approx. 200 ms) must be used for pop noise reduction. 2. Insert resistors between mode select pins (pin 7, 8) and GND, between control pins (pin 16, 17, 18, 19, 20, 23) and GND. 3. Connect a electrolytic capacitor for power supply as close as possible to VCC (pin 1). Remark About "H" and "L", refer to RECOMMENDED OPERATING CONDITIONS.

NEC Corporation assumes no responsibility for any errors which may appear in this document. NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual property rights of third parties by or arising from use of a device described herein or any other liability arising from use of such device. No license, either express, implied or otherwise, is granted under any patents, copyrights or other intellectual property rights of NEC Corporation or others. While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices, the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or property arising from a defect in an NEC semiconductor device, customer must incorporate sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features. NEC devices are classified into the following three quality grades: "Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a customer designated "quality assurance program" for a specific application. The recommended applications of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device before using it in a particular application. Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems or medical equipment for life support, etc. The quality grade of NEC devices in "Standard" unless otherwise specified in NEC's Data Sheets or Data Books. If customers intend to use NEC devices for applications other than those specified for Standard quality grade, they should contact NEC Sales Representative in advance. Anti-radioactive design is not implemented in this product.
