Conventional CD players could only reproduce up to around 20kHz.
Sampling takes place to convert digital signals to analogue. In this process, digitised sound with a frequency range of up to about half the sampling frequency
is reproduced. For example, in the case of CDs which are sampled at a frequency of 44.1kHz, playback is possible for up to half that, or 22.05 kHz. Sampling
is set at 44.1kHz to achieve reproduction of highs in the neighborhood of 20kHz.
Burr Brown advanced segment type 24-bit D/A converter
After high sampling the data is processed by an advanced segment type Burr Brown 24-bit D/A Converter which offers superior dynamic characteristics and
is resistant to clock jitter. Since the D/A Converter’s internal structure is a 4DAC configuration which operates on L/R± differential, higher accuracy in D/A
Conversion is afforded.
Display OFF function
Turns off the display circuits when a CD or other source is being played, preventing pulse noise from the display section from affecting sound quality.
Harmonic elements included in high range add richness and depth to sound.
The format specifications for CD deemed the high frequency elements above 20kHz as inaudible by the human ear, and thus they were not recorded. And
even if such high frequencies were reproduced during playback, they would be detected as noise elements and removed by a digital filter. Not only that, but
phase distortion was introduced as a result of noise cut-off by the filter, thereby inhibiting the accurate reproduction of high frequency sounds. Ironically, it is
the harmonic elements contained in this high frequency range that affects the depth and nuance of sound.
96kHz sampling enables reproduction of sounds faithful to the original source.
The 96kHz Sampling D/A converter samples at a much higher rate than the usual 44.1kHz to offer reproduction frequencies as high as 48kHz (half the sam-
pling frequency of 96kHz), surpassing the format specifications for CD as the first such D/A Converter for car audio use. By broadening the sampling range,
it becomes possible to reproduce the subtle nuances and depth contained in harmonic elements while reducing phase distortion in the high frequency range,
delivering the full expressiveness and natural resonation that is inherently present in sound.
Copper Plated Chassis prevents sound deterioration
Uses a copper plated chassis to minimize the generation of spurious electrical current which can adversely affect sections that have a bearing on the signal,
as well as noise interception caused by electrical shielding effect. By incorporating a zinc diecast panel, with its large specific gravity, high rigidity and low
resonance, sound quality deterioration due to vibration is reduced. And by externally positioning noise generating parts such as the power supply, VFD
devices for the display and the drive mechanism, the sources of noise are eliminated.

Keeping great sound in and noise out: The HX-D2’s DC/DC converter
Consisting of only the highest quality components – from the chassis to the wiring and fuses – the HX-D2’s external power supply is the heart of this audi-
ophile-grade main unit. With its six-sided shielded casing, this design thoroughly keeps out noise, even during high load bursts. And to prevent any vibration,
Clarion wraps this high-quality power supply in an aluminum diecast casing, and a copper-plated chassis. Internally, the HX-D2’s power supply utilises
toroidal choke coils, which minimise car noise and power loss. The unit also utilises a large-capacity, low-impedance condenser, which allows this external
component to supply pure power. Clarion takes this a step further by equipping the power supply with a gold-plated connection terminal, which minimises
power loss.
World’s finest 0.7cm-step Digital Time Alignment
This function lets you set each speaker in a maximum 8-channel system to deliver the same acoustic effects with pinpoint accuracy, regardless of the lis-
tener’s seat position (FRONT-L, FRONT-R, FRONT, REAR, and FULL SEAT position selectable). The Front L/R, Rear L/R, Centre speaker and Subwoofer
work in harmony to create a seamless soundscape. It’s possible to quickly and easily select the acoustic pattern of the system, or choose different settings
according to the number of passengers or type of vehicle. (Adjustable range: 0 – 500cm, in 7mm steps)
