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.
