So what is
d-tech
 D-TECH
is
a state of the art technology that gets more power out of an
amplifier with less wasted power than was ever before possible.
D-TECH is
a type of digital switch-mode
power amplification design
that is highly advanced and delivers a tremendous amount of power and very
clear sound in a very small size.

Features of the new digital power amplifier
from tafn
D-TECH
uses a special type of switch-mode power supply technology, which
ensures that in the event of fluctuations in mains power, the output
remains stable because of D-TECH’s fast-feedback system. As added
protection, the power amplifier can withstand any sudden cut, drop or
surge in mains power. The soft-start feature ensues that after power
returns to operating levels, sound increases gradually rather than all
at once, which safeguards the power amplifier and speakers.

Thanks to its extremely low output impedence,
D-TECH
has a very high damping factor, which gives it more control over the
cone movement of the speaker, and therefore a realistic, rock-solid bass
sound. Even when the power amplifier clips, the damping factor will
remain high, so that the sound coming out of the speakers is still as
solid.
In the event of overloading or a short circuit, D-TECH’s automatic gain
control (AGC) device limits output current automatically. This makes
the amplifier very reliable, and extremely unlikely to sustain damage.
The AGC monitors the output current constantly, and if the current
exceeds its pre-set level, it will restrict the signal to keep the
current within those limits, regardless of how hard the short circuit or
extent of overloading.

The
D-TECH
power amplifier uses switch-mode technology, which generates minimal
heat. It also re-uses energy returned from the speaker rather than
dissipating it as heat or forcing the amp into premature current
limiting.
By generating
less heat, the D-TECH digital amplifier also dispenses with the need for
large heat sinks, making the amplifier smaller and lighter.
GRAPH:
Comparison of heat dissipation loss between different technologies
Class-AB
50% Power loss in heat |
Class-H 30% Power loss in heat |
|
Class-TD 10-15% Power
loss in heat |
D-TECH 5% Power loss
in heat |
|
The D-TECH
power amplifier loses only 5% of energy to heat, compared to up to 50%
for a conventional (Class AB) power amplifier. The
Class-H amplifier
loses about 30%, and Class-TD loses 10-15%. |
With
less heat loss, D-TECH’s digital amplifiers need
nearly half the amount of power to run compared with conventional
Class-AB power amplifiers, which saves on electrical
installation costs and power bills. |

How does
D-TECH do it? We combine the benefits of an advanced
digital power amplifier and a
specially designed digital switch-mode power
supply, to make the amplifier smaller, lighter, and more efficient. |
TAFN
makes digital amplifiers in two series: D-TECH
SERIES, and I-POWER SERIES.
Both series use core D-TECH technology.
|
The D-TECH
SERIES is a digital power
amplifier which is only one unit high but delivers unmatched power for
its size. It uses a state of the art
technology to achieve unparalleled power and very clear sound in a
compact design. The D-TECH SERIES can deliver
several times more power than other amplifiers of the same size and
weight. Read more about it
here.
The
I-POWER SERIES is a digital amplifier which is two units high but again
delivers unmatched power for its size. The I-POWER SERIES can take up to
two ohms per channel while still maintaining a
tight sound. Its special circuitry is designed for low impedence which
can handle high currents effortlessly. This allows it to take up to
four speakers per channel while avoiding problems common to conventional
designs such as overheating and loss of sound quality. Read more about
the I-POWER SERIES here.
