QXpander™ processor  
QX2130FS / QX2130S  
The QX pander chip (QX-2000 Series) is a sound enhancement sound processor based on QSOUND's QX pan-  
der™ technology, and produces virtual 3D sound from ordinary audio signals. This IC requires no special encoding  
of input signals or additional speakers, and so simplifies the development of high-value-added personal computers,  
televisions and audio products.  
Applications  
•
Speaker systems for desktop and notebook multimedia personal computers, televisions, audio equipment, video  
games and other devices  
Features  
•
1) Virtual 3D sound from ordinary audio signals.  
2) No special encoding signals are necessary.  
3) Three enhanced modes:  
4) Internal functions for personal computers: power  
saver function, output muting function and stereo  
bypass function.  
QX1: Pro Listening  
5) TTL-compatible control pins (at 5V).  
6) Low noise (45µVrms)  
QX2: Wide Listening  
QX3: Wow for Games  
7) Low power consumption  
8) Available in SSOP-A20 pin package or SDIP22 pin  
package.
