3 : 4.About the amplifier platform
Congratulations on buying a Powersoft K Series amplifier!
We know you are eager to use your new amplifier, but
please take a moment to read this user’s manual and safety
instructions. In case you have any questions, please do not
hesitate to contact your dealer or Powersoft.
Powersoft is a leading company in the field of high
efficiency audio power management. The Powersoft
switching mode technology has changed the way the
world looks at professional audio amplification: no other
amplifier’s performance comes close for applications
demanding high power and long term reliability. Thanks
to amazing reductions in heat output and weight, without
sacrificing output powers, Powersoft amplifiers can be
used in an unlimited range of PA applications such as opera
houses, theaters, churches, cinema, and theme parks.
K Series has many advanced features, digital control
of many parameters, adjustable maximum m ains consumption, selectable digital presets and a graphic display
that shows detailed information of the status of the amplifier. All K Series amplifiers come with built in Power Factor
Correction. This unique feature ensures that a predominantly
resistive load is presented to mains thus minimizing current
distortion and voltage/current displacement. This leads to
improved performance of the amplifier at high levels of output and avoids mains-voltage collapses, typical of standard
and switching power supplies. Another great advantage of
this technology is that its performance is, to a large extent,
independent of mains voltage. The rated output power does
not vary with load/line conditions.

3 : 2.Unpacking & checking for shipping damage
Your Powersoft product has been completely tested and
inspected before leaving the factory. Carefully inspect the
shipping package before opening it, and then immediately
inspect your new product. If you find any damage notify the
shipping company immediately.

3 : 3.Disposal of the packing material
The transport and protective packing has been selected
from materials which are environmentally friendly for disposal and can normally be recycled.
Rather than just throwing these materials away,
please ensure they are offered for recycling.

Class D technology based amplifiers are highly efficient,
delivering greater power to speakers with reduced heat dissipation: typical running efficiency of output stages is 95%,
with only 5% of input energy dissipated as heat. This allows
for smaller dimensions, weight and power consumptions.
Contrary to conventional amplifiers which achieve highest efficiency only at full rated power output, Class D efficiency is almost independent of output level. Music has an
average power density of 40% of its peak value; this means
that other (non-class D) amplifiers can easily generate 10
times more heat than Powersoft products for the same
sound pressure level.
Powersoft amplifiers deliver crystal-clear highs, and a
tight, well-defined low end: the most accurate reproduction
of an audio signal. Solid time proven design features ensure
extremely high performance in terms of super low total harmonic distortion, optimal frequency response, high power
bandwidth and damping factor across a vast number of application scenarios. Powersoft’s multi patented application
of Pulse Width Modulation (PWM) high frequency sampling
techniques is just one of the many factors contributing to
the K Series’ high performance ratings across the audio
bandwidth.
3 : 4.2. The Show Always Goes On
The K series offers complete protection against any
possible operation error. Every amplifier in this series is
designed to work under a large range of possible conditions, delivering maximum power with maximum safety and
an outstanding long term reliability. Anticipating potential
problems at the design stage means your show always
goes on!
