the D/A converter. The inner and outer pick-ups
guide the laser assembly to precisely track the
digital information on the CD. With the advanced
suspension system, D/A converters and the zero
bit detection circuit, it is easy to see why Clarion
CD players perform flawlessly and with excellent
sound quality.
Clarion’s CD Operational Safeguards
Clarion’s CD operational safeguards allow the
CD mechanism to detect disc size, prior disc-in-
drive detection, foreign object detection, and auto
reload.
A tapered loading-roller precisely centers the CD
onto the drive spindle. Since the roller mechanism
is tapered, only the edges of the CD are touched,
thereby eliminating the possibility of scratches. A
sensor prevents disc loading when one is already
in the player by automatically closing a loading
gate.
These operational safeguards allow safer CD disc
handling, prevent jams from accidental loading of
two CDs, and helps to reduce service problems
by detecting foreign objects in the drive mecha-
nism.
Clarion’s CD mechanism uses photosensors and
LEDs to identify 3" or 5" compact discs. Clarion’s
CD mechanism uses a tapered roller to precisely
center the CD onto the drive spindle.
Audio Signal Processing
Technologies
ADF (Anti-Distortion Filter)
No one can question the benefits of compressed
audio formats such as MP3 and WMA music files:
more songs and more selection. The downside of
this format is sound quality. With Clarion’s embed-
ded Anti-Distortion Filter (on the DXZ865MP and
DXZ955MC), the rich, full sound lost during compres-
sion is restored for dramatic sound reproduction.
ADF also corrects deficiencies of overused CDs. The
benefits don’t stop there, either. From road noise to
sound-hindering interior cabin designs, the environ-
ment inside a vehicle is not an ideal place for optimal
sound reproduction. Clarion’s Anti-Distortion Filter
corrects these problems, preventing high- and low-
range frequencies from becoming inaudible. This
is done without any additional frequency boost to
compensate for the inherent problems, which can
result in muffled, dull sounds generated by mutual
phase distortion.
ADF enhances and corrects sound quality, while a
normal filter alters the wave form.
AC-Processor IV: Cutting Edge Technology
for Total Sound Control
The AC-Processor III is Clarion’s advanced digital
sound processing technology. It was developed
by bringing together various sound quality and
sound field manipulation technologies. It provides
a wide spectrum of features like Dolby Pro Logic II,
Virtual Space Enhancer, Time Alignment, Electronic
Crossovers and Parametric EQ. The AC-Processor
IV has four modes: Pro Logic II, Standard Mode, 2-
Way and 3-Way. With all these features and func-
tions, the AC-Processor IV allows for nearly infinite
system configuration and manipulation.
Dolby Pro Logic II
Dolby Pro Logic II is a matrix sound decoding
technology developed by Dolby
Laboratories that is able to take
any 2-channel source, such as a
CD or radio broadcast, decode
it, and output it as 5.1-channel
sound. Clarion was the world’s
first to incorporate this innova-
tion into the mobile environment,
enabling the sonic experience of a live concert to
be reproduced in your vehicle.
