Chapter 2 System Overview

2.4.10 AUDIO SUBSYSTEM

These systems use the integrated AC97 audio controller of the 845 chipset and an AC’97- compliant audio codec. These systems include microphone and line inputs and headphone and line outputs. The Desktop and Configurable Minitower models include a 3-watt output amplifier driving an internal speaker. The Small Form Factor models feature Compaq Premier Sound consisting of a five-level equalizer designed to compensate for chassis acoustics and a low- distortion 5-watt amplifier driving a speaker for optimum sound. Small form factor and all Workstation models front panel-accessible audio jacks as standard while Evo desktop and configurable minitower models may be upgraded to include front panel audio jacks.
