The Compaq Professional Workstation 6000, models 333 MHz and 333 MHz (with ETR) include
a 5.25", half-height auto-slot load 24X Maximum CD-ROM Drive using the new Constant
Angular Velocity (CAV) technology. This CD-ROM uses a slot load mechanism, similar to car
stereos, where the CD slides directly into the slot in the CD-ROM. Additionally, previous CD-
ROM technology used Constant Linear Velocity (CLV) technology which allowed the disc to
rotate at a faster rate while reading the inner tracks and a slower rate when reading the outer
tracks. Conversely, CAV technology spins the disc at a fixed rate and the data transfer rate
increases as it moves toward the outer tracks. This is the same technology that is used for hard
drives where it has demonstrated excellent performance in high data transfer and fast access
times. Using this technology enables reliable CD-ROM speeds above 8X. The 24X CAV CD-
ROM dramatically increases the access time performance of the CD-ROM in the Compaq
Professional Workstation 6000.

The Compaq Professional Workstation 6000 includes Compaq's PremierSound audio solution.
The PremierSound design incorporates a high performance, custom designed loudspeaker, a
ported (bass reflex) enclosure for extended low frequency output, a low distortion amplifier
(less then 0.3 % at the rated power of 3 W), and 5 bands of fixed equalization with the ESS
Audio 16-bit solution to provide a complete, optimized audio solution.
The high performance loudspeaker and the ported enclosure are designed in conjunction with the
equalization to provide crisp, clean, wide bandwidth audio from a small, integrated mono
solution. The low frequency capability of the enclosure and speaker are dramatically better than
typical business audio solutions.
The five stages of fixed equalization are used to "tune" the audio system to the acoustic
environment, lower distortion and smooth the response of the speaker. The tuning allows us to
shape the frequency response to provide exceptionally clear, natural, voice quality, whether
under a desk or in a rack.
The result is a well-balanced audio system capable of delivering clean, undistorted output at a
level needed to support an office environment.
To use the audio capabilities, volume controls, headphone and microphone connections are
conveniently located on the front of the chassis above the speaker, and line in/out and
microphone connections are provided on the back of the chassis.
