Source Units – Technologies
a slightly different text display method.
• Interface is not equipped with a pass-through
CeNET connection. Installers must use Clarion’s
CCA519 to connect additional CeNET-controlled
components.
SIRCL3
These units allow for the reception of Sirius Satellite
radio. The source unit AM/FM presets can be used
when in Sirius mode to store your favorite stations.
Station information, artist and song title information
will be displayed on the source unit when used with
any of these modules
DCZ625
The DCZ625 is a six-disc CD changer compatible
with all CeNET enable source units.
VCZ625
The VCZ625 is a six-disc DVD changer compat-
ible with all CeNET enable source units. This
changer will also decode MP3 files from CD, CD-R
or CD-RW discs. (Except CMD4 and M455)
DVH940
The DVH940 is a surround sound processor
compatible with VRX and MAX series source
units. This unit decodes Dolby Digital and dts sur-
round sound information. The DVH940 features
electronic crossovers, parametric equalizers and
time delay adjustment for the center and rear
channels.
TTX7501Z
The TTX7501Z is a TV Tuner module that inte-
grates with many source units. The AM/FM radio
preset buttons can be used to store your favorite TV
stations for easy access. The TTX7501Z features
a four-channel diversity antenna input for optimum
picture quality.
Sound Quality
1-Bit and 24-Bit Digital-to-Analog Converter
Clarion’s 1-bit D/A bitstream converter produces
signal levels that are either “one” or “zero.” Because
of this, the conversion process is not prone to the
types of errors found in the multi-bit D/A conver-
sion. The results of a 1-bit D/A conversion is excel-
lent linearity and a virtual absence of distortion.
In Clarion’s 24-bit D/A converter (in the DRZ9255,
DXZ865MP and DXZ765MP), the digital code of
the “one” or “zero” bits is read more often than the
standard 1-bit decoding rate of 44,100 bits per sec-
ond for audiophile sound quality and more detailed
music quality. A 24-bit D/A converter greatly reduc-
es linearity errors and notch distortion, resulting in
superior sound and less system noise.
96kHz Digital to Analog converter
Few components have as large an effect on the
ultimate sound quality of a source unit as the D/A
converter. It is this devices that interprets the 16-bit
digital information recorded on a CD and converts
it back into an analog waveform - or music. Any
errors or frequency response limitations of the D/A
converter directly limit the quality of the reproduced
sound. Car Audio magazines and enthusiasts
agree that the Clarion DRZ9255 is indeed one of
the finest sounding source units on the market -
the key reason - the Burr-Brown 24-bit 96kHz D/A
converter.
The sampling rate (or how often the D/A converter
converts a digital signal back to analog) defines
the highest frequency that can be reproduced. A
conventional D/A converter operates at 44.1kHz
and as defined by the Nyquest Frequency (the
