The Compaq Professional Workstation AP500 features a 5.25”, half-height tray-load 32X
Maximum CD-ROM Drive using the new Constant Angular Velocity (CAV) technology.
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
32X CAV CD-ROM dramatically increases the access time performance of the CD-ROM in the
Compaq Professional Workstation AP500.

The Compaq Professional Workstation AP500 PremierSound audio system is a solution
optimized for workstations.
The signature performance characteristics of a PremierSound
audio system are exceptional sound output and clarity from a completely integrated, “no
desktop clutter,” audio solution.
The PremierSound audio system is comprised of several subsystems, each individually
optimized to work as a complete solution. The end result of the interaction between the
susbystems is a well balanced, “no desktop clutter,” audio system capable of delivering clean,
undistorted output at a level needed to support an office environment.
CUSTOMER BENEFITS
•
“No desktop clutter.”
Compaq PremierSound is integrated in the AP500. This provides
more free space on desktops.
•
High-performance loudspeaker with long excursion
. Provides crisp, clean, wide-
bandwidth audio from a small-integrated solution. The voice clarity and low frequency
output of the speaker is dramatically better than current integrated computer office
products.
•
Low distortion.
PremierSound utilizes an audio power amplifier that delivers a clean,
undistorted signal.
This amplifier is conservatively rated at 5 watts RMS and is
designed to take full advantage of the loudspeaker’s output capability by providing a
large, low distortion, audio output signal.
•
Five stages of fixed equalization.
The five stages of fixed equalization incorporated
in the electronics are used to “shape” the system frequency response in various
listening positions. The system frequency response is manipulated to provide smooth,
natural voice reproduction and high-quality CD playback.
