瑞士顶级解码器DOLSING D1.0（DOLPHIN）系列现已登陆，DOLSING来自希腊神话中的灵
感，而(DOLPHIN)就是里面的主角。2008已经进行开发历时3年的时间现在终于见到其真
容。其简洁的外形且华丽到极致绝对是无可挑剔，整机是由一体实心高级铝材经过精密的
机械加工和人手打磨而成，它外形所发出的魅力已经不是一个产品，而是艺术品
DOLSING出自一个航空级的工作室，这个工作室专门为航天器设计各种精密零部件，而出自
这个工作室的零部件每个都经过非常可靠的测试才能够允许送到装配位置上。DOLSING
D1.0里面的每个零件都经过600小时的通电测试状态后才挑选出来装配，装配完成整机也要
经过300小时的通电运行。如此严格的测试使得DOLSING D1.0要经过比较长的生产时间，也
正是这样使其身份价位昂贵
D1.0不是单纯的一个机器，它融合了多个不同地方的设计师精髓所在，DOLSING认为声音不
是一个单体而是一个团体包括机器也应该是一个团体，这样表现出来的声音才真实，所以
D1.0命名在（DOLPHIN海豚）系列里面，而表现出来的是最具人性化声音。也是这样D1.0在
调教声音时有多位的交响乐成员在聆听，为了得到理想的声音调教时间经过3个的季度，用
这么长的时间调教声音是为了找音乐的共识，DOLSING认为音乐不只让一个人听是让更多会
听音乐的人听。D1.0其内部也内置各种优秀性能的电路，AC冲击保护电路，模拟电池并联
稳压电源，有源频带展宽的带通滤波器，独特的jieetr处理电路，这些都是DOLSING专门开
发的也是独有技术拥有者。从DOLSING开发人员得知在后期开发的产品中会加入一个史无前
例的装置，音响电源电路中的顶峰装置，它将电压和电流与空气的中的微小元素所产生的
变量结合起来处理，使得原来的电源得到极高的优化。此装置非常特别，而由于用在后期
的产品中所以还没公开

Simulated battery parallel regulated power supply
When load current varies, circuit will automatically regulate the voltage and
current of the regulating transistor to keep the output parameters invariant,
so as to supply stable output voltage and current. Battery parallel regulated
power supply is superior to common series regulated power supply in terms of
such technical indicies as internal resistance, ripple factor and transient
characteristics, and can compare with dry batteries, or part of its functions
may surpass those of dry batteries. Because its excellent characteristics
(such as high stability, high signal-to-noise ratio) are very fit for
occasions with high stability needs, simulated battery parallel regulated
power supply can easily satisfy the needs with either small power supply or
large dynamic power supply, reflecting its excellent hi-end performance. This
power supply has integrated MOS and micro IC, and each of the components is
strictly selected to reach the minimum deviation.
Surge protection circuit
DOLSING surge protection circuit can make reaction at a high speed to the
external surge current and voltage, and cut off the instant variation of
harmful current and voltage from the machine, so that the machine can be
instantly separated from external surge current and voltage and keep safe
operation. Surge protection circuit is completely supplied by an independent
power supply and separated from the main power supply to avoid the
electromagnetic interference. It will run as long as the machine runs. When
connecting to the power supply, the surge protection circuit can fully access
to its working state after about thirty seconds in standby.
Active bandwidth expansion + bandpass filter
In the audio channel, limited bands have a very large effect on the sound.
Although many bands in the digital channel are outside the extent of human’s
hearing, these bands truly exist in digital circuits, and have an important
effect on the variation of tones. DOLSING reasonably establishes the active
bandwidth expansion in the digital audio channel, and all the audio signals
that pass through the digital circuits are highly processed to recover the
original audio signals as far as possible. After a precise signal recovery
process, DOLSING’s inner bandpass filter will integrate audio signals ranging
close to human’s hearing and process some harsh noises or miscellaneous
interference to get the perfect audio output.
External structure with lower acoustic resistance
There are sounding body/bodies and sound transmission body/bodies in the sound
field. And there exist associated harmonic of the sound in the distance in
which the sound from sounding body reaches to human ears through sound
transmission body, especially in the same space. This kind of associated
harmonic is produced from refraction by the objects in the same space. In
addition to the acoustic materials in the space that can effectively process
this kind of refracted harmonic, another solution of dealing with the harmonic
is to reduce the sound refracting surfaces in the space. DOLSING’s design
will not give up any scheme to improve the sound effect. By that, the external
structure for DOLSING is designed in such a graceful and linear style.
Besides, its reasonable outline distribution and special treatment of curved
edges bring about very low acoustic resistance refraction for DOLSING,
especially good at handling of refracting surface for the acoustic resistance
harmonic of the second and the third waves at facade, thereby further reduce
the harmonic with harmful effect and present a hearing environment with much
more accuracy. In the practical tests, DOLSING’s coefficient of acoustic
resistance at façade is the minimum among the existing hi-end devices. Not
only the acoustic resistance coefficient, but the wind resistance coefficients
obtained in these tests reflect credit on DOLSING. Here the reason of the
tests for wind resistance of coefficient is the existence of sound pressure. A
space where exists sound movement is not a singleton, but a mixture, which
contains various sound movement, including vibration of sounding body, air
movement of sound transmission body and harmonic wave from all kinds of
refractile bodies. Except the vibration from sounding body and refracting
harmonic passed to the machine, the most large vibration source is air
movement. The vibration of the air will produce airflow, whose movement will
bring wind resistance to the machine. In a hearing environment, common people
or the maker will not take account of wind resistance. However, DOLSING will
take the tiny digits into account for reducing the external vibration to get
more stable figures.
Parameters with higher acoustic fidelity
Active laser optical/electric filtering power accelerator DC-turbo
DC-turbo is a power device that specially developed and designed by DOLSING.
The unique function of this device is the summit of an audio power circuit. It
combines and processes the variables generated with voltage and current by
minor elements in the air, so that the original power will get extremely high
optimization, which makes sense to its name DC-turbo in a DC circuit. The main
job of DC-turbo is: since the (optical/electric) conductor which is placed in
the air suffers interference from the impurities in the air, and micro-
interference or vibration interference from external elements, which will lead
to a certain obstacles to the conductive effect of the (optical/electric)
conductor, especially for the high-quality communication channels. The
external interference will reduce the quality and efficiency of the
(optical/electric) conductor, and in turn reduces the physical quantities
which pass through the conductor. In the natural world, the largest external
interference for high-quality conductor is floating quantum elements and the
fluctuations of mass, both of which can affect the conductibility and function
of conductor in instable and irregular ways. The floating elements invisible
to human eyes and the fluctuations (tiny ones) of mass imperceptible to human
feeling are always being ignored, though they do exist and involve in
irregular physical movement at any point in time. For the main conductor, this
kind of movement is harmful physical variable, which will affect the function
and efficiency of main (optical/electric) conductor directly. This device can
reduce or filter the inner and external sources of micro interference (air
impurities interference or vibration interference from external and inner
device), playing a role in optical/electric filtering, and the
(optical/electric) conductor which go with this device will get cleaner and
higher flux guide conditions that make the signals of the conductor much
faster and quieter than other conductors.
Jieetr
D1.0 is equipped with built-in processing circuit of jieetr, which is
different from the common jieetr. General equipments process the jieetr to the
minimal level, and instead D1.0 reduces jieetr to a certain value but not the
lowest. DOLSING believes that lower jieetr must indicate a good machine,
however, it must not ensure any melodious sound. Thus, D1.0 turns jieetr to a
reasonable position with ideal acoustic effect.
USB driver
USB input uses 1.1 general audio device protocol interfaces which are
applicable for the following operating systems:
Windows me
Microsoft windows 98SE
Windows 2000 series
Windows XP series
Windows Server 2003 or later
Apple computer Mac OS
Linux
When any of above mentioned operating systems is connected with DAC USB, the
system will automatically identify USB Audio device and install related
application drivers, or the drivers will be installed according to the tips
showed by the system. After drivers installed, the computer will set the
device as the system default audio device if there are many audio devices
coexist. The operating method (to take Windows XP as an example): to click
(Start) - (Settings) - (Control Panel) - (Sounds and Audio Devices), select
USB Audio DAC device in [sound playback - Default Device] column of the
(audio) Setting page, and then select “apply” in the (audio) Setting page,
click (Volume) button in the [sound playback] column, that will popup volume
setting window, push up/down the (waveform) control rod in the window to
adjust USB input volume.
