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:
QX1: Pro Listening
QX2: Wide Listening
QX3: Wow for Games
•Block diagram
4) Internal functions for personal computers: power
saver function, output muting function and stereo
bypass function.
5) TTL-compatible control pins (at 5V).
6) Low noise (45µVrms)
7) Low power consumption
8) Available in SSOP-A20 pin package or SDIP22 pin
package.
