2.4.9 AUDIO
SUBSYSTEM
All models feature an embedded Sound Blaster 128 PCI audio system using the AC’97 ver. 2.1
specification-based design. The subsystem features a Creative Labs, Inc. ES1373 audio controller
and a Cirrus Logic CS4297A audio codec. The output of the audio codec is applied to a 3-watt
amplifier that drives the chassis’ internal speaker. Standard microphone and line input jacks are
provided as well as a tri-purpose headphone/line/digital output jack that allows the use of
headphones or a pair of powered speakers (optional). The output jack also provides a digital audio
output signal using the Sony/Philips Digital Interface (SPDIF) format (officially known as IEC-
958).
