I-POWER series
technology
The I-POWER SERIES
features a type of digital switch-mode power
amplification technology that is highly
advanced and delivers a tremendous amount of power and very clear sound
in a very light-weight design. The
I-power series is designed to handle higher
speaker loads, up to four speakers per channel without any drop in sound
quality as more speakers are added.

The I-POWER
digital power amplifier maintains output
voltage at stable levels, even when up to four speakers are added per
channel. This
control feature sets it apart from conventional amplifiers, which start
reducing output voltage well before overloading point has been reached.
Providing high damping factor even when clipping.
How D-TECH output voltage drops with increasing
speaker load compared with others

The graph on
the right shows that maximal output voltage remains at a constant
level until a pre-set point is reached, regardless of how great
is the load. Compare that to conventional
amplifiers, which start decreasing maximal output voltage straight away,
as soon as any load is connected. Using the
I-POWER digital power amplifier, you can even
add four speakers to each channel without noticing any reduction in
sound quality. The amplifier will increase power accordingly, but with
no reduction in output voltage.

After a pre-set overloading
point is reached, I-POWER’s automatic control mechanism (AGC) comes into
effect, to limit output current automatically. This provides absolute
protection in the event of a short circuit, which conventional power
amplifiers cannot match.
I-POWER SERIES built-in protection features
I-POWER SERIES’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.
In the event of a short
circuit, the AGC limits the signal immediately, which protects the
amplifier from shock caused by a surge in current. With conventional
amplifiers, there is a short delay, while the amplifier takes energy
stored in capacitors to tide it over. That delay in adjustment can prove
fatal to the power transistors – but not with I-POWER, where the AGC
limits the signal instantly, ensuring the power transistors adjust to
the short circuit in time.
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.
