QXpander™ processor
QX2130FS / QX2130S
The QX pander chip (QX-2000 Series) is a sound enhancement sound processor based on QSOUND's QX pander™ 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
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 (45µV
rms)
7) Low power consumption
8) Available in SSOP-A20 pin package or SDIP22 pin
package.
