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.
The QX2130FS and QX2130S are QXpander™ multimedia ICs that add virtual 3D sound to ordinary audio signals without special encoding or extra speakers. They are intended for use in personal computers, televisions, audio equipment, and video‑game systems.
Key features include three listening modes (Pro Listening, Wide Listening, Wow for Games), power‑save and mute functions, TTL‑compatible control pins, low noise and low power consumption, and availability in SSOP‑A20 or SDIP22 packages. The datasheet lists absolute maximum ratings, recommended operating conditions, analog and digital characteristics, and control‑mode details.
