Source Units – Technologies
The EA1251B works with CeNET head units. The
EA1276B was designed to provide text informa-
tion on the CMD4A and M455A. These decks use
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 informa-
tion 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 com-
patible with VRX and MAX series source units.
This unit decodes Dolby Digital and dts surround
sound information. The DVH940 features elec-
tronic crossovers, parametric equalizers and time
delay adjustment for the center and rear chan-
nels.
TTX7501z
The TTX7501z is a TV Tuner module that integrates
with many source units. The AM/FM radio preset
buttons can be used to store your favorite TV sta-
tions 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 conversion. The results of a 1-bit D/A conver-
sion is excellent 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 second for audiophile sound quality and more
detailed music quality. A 24-bit D/A converter
greatly reduces 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 con-
verts 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 repro-
duced sound. Car Audio magazines and enthusi-
asts 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
