Here we have what you need. In this page you will understand the car amplifiers
that 
Davidart Technology Co., LTD. designs and manufactures are the best all over the
world.
Our goal is direct comparison between live and recorded music, and then to
reproduce
perfect, authentic, and high-fidelity sound. Furthermore, we strongly guarantee
that our
strict, innovative, dedicated approach leads to the apex in technology and
performance.
History
The so-called high-quality car amplifiers many years ago
only enlarged the voice. They
were different from traditional home high-graded amplifiers. During tens of
years, our
all dedicated engineers of great experience in researching how to reproduce
perfect,
authentic and high fidelity sound have been searching for solutions to
questions. They
work endless hours in the laboratory every day and work on one project at one
time.
The power amplifiers that the team of dedicated engineers designed ranked the
top in
professional magazines for times.
To share a passion for endless quest and to create a car audio system with great
sound,
we finally established the Davidart Technology Co., LTD. in November 1997.
Research & Development
During the primary step, we use CAD (computer aid design) to reach the schematic
design and the final design of PC boards.
In the next step, we have the test for the stability in high temperature and low
load ( 2
ohm or 0.5 ohm for high current amplifier series). The step is imperative.
The final step is that acoustic engineers tune the voice.
They not only are professional
connoisseurs of music but also have strong background in electronic engineering
as
well as great experiences in tuning the sound. With their
proper adjustment and application
of transistors, capacitors, IC, and so on, the authentic
sound is presented. We test not
only for the nature of the overall acoustic field but also for individual parts
including-for
example: the presentation of string instruments (violin,
viola, cello, and so on), brass
wind instruments (sax, French horn, oboe, clarinet, and
so on), beat instruments
(xylophone, timpani, drum, and so on) and human's voice
(soprano, alto, baritone, and
bass). Besides these, we also care so deeply and
meticulously about every detail.
We do not stop repeating the three steps until no more
improvements need to be made.
Consequently, our products satisfy our high expectation
and your quality requirements.
Manufacture
What our amplifiers have
achieved is the result of our applying to highly leading edge
technology. For instance, the SMT (Surface Mount
Technology) is a process close to
perfection. The manufacturing process comprises
discrete components and integrated
circuitry. High speed robotics place thousands of
components per second. When the
components of the SMT are placed, the PC board is taken
to a manufacturing cell team
where heat sinks, power supplies, and large capacitors
are placed by hand.
Another technology is used to protect the amplifier
against overload, external, and
internal short circuits. The output signal path is
totally free of any fuses or sound-
degrading resistive components often employed for
overload sensing. Our amplifier is
designed to surpass the highest safety and
electromagnetic interference standards.
Moreover, if the situation is a "sliding bias"
class A/B design with all drive circuitry,
the result is to operate in class A.
In addition, we attach importance to the process of
burning test that many other factories
neglect. This significant process tests for whether or
not the products will be all right
under high temperature.
