ume sliders that are implemented in the system, thus improving the end-user's experience with the
PC.
The information in the Extended Paging Registers will also allow for automatic configuration of
microphone inputs, the ability to switch between SPDIF and analog outputs, the routing of the mas-
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 STAC9752A/9753A also offers two 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 STAC9752A/9753A is designed primarily to support stereo (2-speaker) audio. True AC-3 play-
back can be achieved for 6-speaker applications by taking advantage of the multi-CODEC option
available in the AC'97 architecture and supported by the STAC9752A/9753A. Additionally, the
STAC9752A/9753A provides for a stereo enhancement feature, IDT Surround 3D (SS3D). SS3D
provides the listener with several options for improved speaker separation beyond the normal 2- or
4-speaker arrangements.
The STAC9752A/9753A can be SoundBlaster
used with IDT’s WDM driver for Windows 98/2K/ME/XP or with Intel/Microsoft driver included with
Windows 2K/ME/XP.
