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 for desktop and notebook multimedia personal computers, televisions, audio equipment, video Speaker systems
games and other devices
•Features sound from ordinary audio signals. 1) Virtual 3D
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 (45µVrms) 7) Low power consumption 8) Available in SSOP-A20 pin package or SDIP22 pin package.
