Overview
Multimedia ICs 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 (45µVrms) 7) Low power consumption 8) Available in SSOP-A20 pin package or SDIP22 pin package.
