Chapter 2 System Overview

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).
