Key Specifications
ter volume slider to the proper physical output, and SoftEQ configurations. The fully parametric IDT
SoftEQ can be initiated upon jack insertion and sensed impedance levels.
The STAC9752/9753 also offers 2 styles of PC BEEP; Analog and Digital. The digital PC Beep is a
new feature added to the AC’97 Specification Rev 2.3.
The STAC9752/9753 is designed primarily to support stereo (2-speaker) audio. True AC-3 playback
can be achieved for 6-speaker applications by taking advantage of the multi-CODEC option avail-
able in the STAC9752/9753 to support multiple CODECs in an AC'97 architecture. Additionally, the
STAC9752/9753 provides for a stereo enhancement feature, IDT Surround 3D (SS3D). SS3D pro-
vides the listener with several options for improved speaker separation beyond the normal two- or
four-speaker arrangements.
The STAC9752/9753 can be SoundBlaster
with IDT’s WDM driver for Windows 98/2K/ME/XP or with Intel/Microsoft driver included with Win-
dows 2K/ME/XP. SoundBlaster is a registered trademark of Creative Labs. Windows is a registered
