Clarion Japan has been in China, Japan, the other two brands as Pioneer or Alpine in the country so famous. The reason seems to

Clarion brand manufacturers or suppliers may be more emphasis on the domestic cost of production, but do not start focusing on the

booming domestic car audio market. However, enthusiasts will certainly not forget the D2 name, because it can be said in some sense,

represents Clarion s image in the eyes of people, and its pure sound design, has also been very critical of those consumers of all ages.

All in all, I would be a Clarion fans, from the early 1990s, came into contact with its products, the beginning I always thought they do

not pay attention to after-market car audio, most of the energy on the areas with the depot facilities. Can be made to the late

1990s, the first exposure to it to sound a clear orientation DRX9255EXL host, the impression that it began to change, then the sound

quality of this host can be described as unique, special deep impression until now, but unfortunately This host is a Western version,

played it at home can be one of the few owners really! Until 2000, the Asian market s first car audio console with HDCD decoding HX

-D1, the impression it have a better understanding, because the HX-D1 sound quality than the other models is more outstanding in

the past, when the true There is a refreshing feeling. Now the market is more popular high-end Clarion another new model HX-D2,

can be said that the previous generation flagship host DRX9255EXL and HX-D1 alternative models, although it does not fashionable

MP3, WMA and HDCD playback, but the HX -D2 or the appearance of both the sound quality, are that it s in the car audio field has a

step forward.

The first design concept reflects the sound
A good equipment, starting with the design concept began, every little detail can not be ignored, it was said, every detail it

represents a sound symbol, if you want to be able to show up all the symbols, you have to pay attention to each the details.

Although the size of a standard D2 1DIN size, but, though small, can be perfectly formed. The first is the host of its copper shell, to

see that this is a boy, the industry s first 96kHz sampling digital sound processing; Burr Brown 24Bit D / A converter, 4-way electronic

crossover, 5-band parametric equalizer, 8-channel the RCA up to 4V output, digital time delay function, so that sound quality be

enhanced further, independent separate DC / DC converters to ensure stability of supply, CeNET network control, optical input /

output, vacuum fluorescent display, external simply set the amplifier output RCA low-level signals, etc., make it a lot of fans pay

homage to the products.

Copper used in the framework of D2 seems to be the host for all brands of high-end products, patents, copper shell can disrupt signals

to maximize inhibition of stray current, less susceptible to outside interference, to inhibit the effect of quality degradation, so that the

host work in a more stable state. Detail is also reflected in the output signal line, D2 line with a silver-plated SK: 6N copper output line

for RCA, 6N purity is, N is the 9 English narrow, that is, 99.9999% purity copper wire, all RCA output high-performance copper cable

used in all of this to ensure that the audio signal output to the amplifier by the smallest losses. Meanwhile, the internal circuit board

with a four-epoxy circuit board, with the power of this technology will separate the ground at different levels, to reduce the role of

impedance ground and power supply to stabilize the drive circuit, a great improvement on the quality help.

Ensure high quality sound on the details of the display also fell, D2 of the display also features auto-off feature when playing a CD or

other audio, the display circuit automatically shut down to avoid damage to the electron pulse noise, the sound quality. Independent

external power supply DC / DC converter, is this another highlight of the host, the host completely separate power supply and to

avoid interference between high voltage power supply problem, keep a good supply of pure power, so that the host job In the more

stable state, and seeks to achieve the noise completely ruled out.
Many of the world s first voice and rich details
It is worth mentioning that the application in the industry on the world s first D2 96kHz sampling digital signal processing, high-rate

sampling, the music can get more detail, just as the camera s high resolution, so that a clearer picture of the details of the outline. We

all know that regular CD sampling frequency of 44.1kHz, and the frequency of the signal D2 read his twice, that will not miss any

detail. There is a high sampling rate is high-frequency extension of the benefits will be higher, the CD s sampling frequency to 44.1kHz,

because the human ear listening range of 20kHz, so more than 20kHz UHF signal was cut off filter . However, this process will result in

clipping phase distortion, destruction of high-frequency signal fidelity; but was cut off on the high-frequency harmonic components

but also on the depth and charm to keep the sound of great significance. In order to reproduce the original audio signal the depth

and charm. HX-D2 s D / A converter sampling at 96kHz on decoding, for the first time in the car audio system to achieve a theoretical

maximum of up to 48kHz high-frequency regeneration, can be reproduced on the CD recording of various musical instruments in the

subtle charm, carefully D2 will find listening to the high frequency part of the details of the special and more.

D2 over-sampling the audio signal is encoded into a digital signal, word length is 24bit, the 16bit word length than regular CD length by

a third. Adjust the volume of high-tech technology also used crystal, the use of electronic volume IC Burr Brown United States, to

achieve a volume increase or decrease the interval to reach the world s first 0.5dB steps. By setting, users can choose 0.5dB or 1dB

accuracy. Most of the market compared to the control precision of the host, this technology has been slightly ahead.

In addition, it is 0.7 cm interval of time delay control function is considered to be of similar technology in the world s most

sophisticated, using this feature, you can for 8-channel sound system to set each speaker, no matter what the listener is located a

seat, you can achieve the best sound. 5-band parametric equalizer to the audio signal is divided into five major bands, the user can

choose according to their needs need to adjust the band, but felt it was too small number of frequency bands, can not meet the

needs of most customers, compared with Other high-end models like the Pioneer P90, Alpine H900 or 31-band equalizer trivial.

As a replacement for D1, will not let fans disappointed.
Powerful and complex, users challenge
Generally speaking, high-end positioning of the D2 is a very particular about the details of the models, especially in the area as a further

improvement of sound quality was received good results, whether it is the technology used or the actual results are favorable. On the

whole tone, in addition to the details of exaggerated feeling, which is high-quality-level system requirements, but also that its speed

too slow, and Pioneer P90 tough sense of speed compared to a completely different sense of style, is called: radish vegetables; all

have love, this is left to further business enthusiasts do.

D2 is definitely a recommended high-end host, while the use of D2 players must have extensive experience with the equipment. It is

rich with good physical function, can play through the performance of the users, showing the entire system is definitely the

opportunity for a higher level of sound performance. If those features are used to playing a simple host of players who want to take

full advantage of D2 of these complex functions, this is the greatest challenge.
