So what is the New Class-D (D-TECH)
D-TECH
is cutting-edge technology that gets more power out of an
amplifier with less wasted power than was ever before possible.
D-TECH
is
a type of 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.
What are the features of
a D-TECH
amplifier? And
how do they benefit me?
A
D-TECH
amplifier generates
one-tenth the heat of conventional amplifiers. So it can work with much
less air movement. This reduces fan noise, and contamination of the unit
in normal use. In addition. the amp is more reliable because it is not
subjected to excessive heat.
A
D-TECH
amplifier can use smaller heat-sinks, making the amplifier smaller
and lighter.
A
D-TECH
amplifier handles reactive (inductive) speaker loads easily and
effortlessly. It re-uses the energy returned from the speaker rather
than dissipating it as heat or forcing the amp in premature
current-limiting. This ability makes
D-TECH
models extremely resilient.
D-TECH
has a very high effective switching frequency which allows the use of
low-pass filters with almost no phase shift in the audio band. Result:
Better sound.
High
efficiency: High power output to the speakers, low power requirement
from the wall outlet. Since the amp needs only a little AC power to
operate, you'll have smaller AC power bills over the life of the
amplifier. And you can plug several
D-TECH
type amps into a 20-amp circuit.
Is a switch-mode power
amplifier the same as an amplifier with a switching
power supply?
No, they are two different things.
A switch-mode power amplifier processes the signal. A switch-mode
or switching power supply processes the AC
mains power.
A switching
power amp is very efficient and produces little heat. A switching power
supply reduces the weight and size of the amplifier.
D-TECH
series have both.
Protection
A D-TECH
amplifier will work from 150 V
to 260 V without any change in the sound quality and power output and
withstand severe electrical fluctuations.
A D-TECH
amplifier is soft
start.
A D-TECH
amplifier
is protected against
overload
A D-TECH
amplifier is protected against overheat
