Regulatory information | vii
Electrostatic Discharge (ESD)
Electrostatic discharge (ESD) is one of the most signicant factors leading to damage and failure of a wide variety
of electronic components.
Poor handling can cause internal damage, which is
invisible. This internal damage can then cause electrical
failure or reliability problems.
It is recommended that all workstations where
Electrostatic Discharge Sensitive devices (ESDS)
and assemblies are handled outside of full static protection
packaging (i.e. within static control areas) should be provided with some form of ground conductive or dissipative
ooring.

7 : 1.Welcome
Congratulations on your purchase of the Powersoft
IpalMod module.
We know you are eager to use the IpalMod module, 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.
The IpalMod is a one channel amplier modules specically designed to drive high efciency low-impedance loudspeakers: it integrates the Powersoft’s patented Differential
Pressure Control technology that optimizes sonic performances of the amplier/transducer/cabinet/environment
system and is specically designed to fully exploit the
potential of the IPAL compatible transducers.
The IpalMod shows amazing gures in terms of both
output voltage (180 V
being able to drive even the most demanding applications
of self powered subwoofers and can be equipped with any
Powersoft or third-party DSP solution.
The new design of the power supply equipped with PFC,
reduces power consumption while enhancing reliability and
consistency in all operating conditions.

7 : 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 nd any damage notify the
shipping company immediately.
7 : 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.
7 : 4.Differential Pressure Control
The Differential Pressure Control – DPC – is the core
technology of the Integrated Powered Adaptive Loudspeaker
system, also known as IPAL.
DPC makes IPAL systems efcient and reactive
®
DIFFERENTIAL
PRESSURE CONTROL
PATENTED
The differential pressure measurement, senses the difference of pressure between the front and the rear sides
of the radiating diaphragm and uses this information to
alter the behaviour of the transducer, according to the real
boundary conditions. Thanks to this innovative approach
to full boundary conditions feedback processing, the IPAL
system dramatically improves the electroacoustic efciency
in terms of high SPL and sonic performance of the sound
reinforcement system.
The IPAL system combines a high-efcient transducer
with a high-power switching mode amplier that embed a
fast and effective ZeroLatency™ DSP. The DSP performs
the double operation of both managing the loudspeaker
processing and taking care of the differential pressure control signal. IPAL establish a global feedback between the
electrical and the acoustic domains.
Thanks to the rich graphic user interface – GUI – it is
possible to weight and customize the feedback between the
electrical and the acoustic domains. Two operating modes
are available: Virtual Transducer and Pressure modes.
7 : 4.1. Virtual Transducer mode
The Virtual Transducer mode is based on the principle
of virtual loudspeaker emulation: once dened the desired
reference loudspeaker model (speaker designers can synthesize any desired driver using the GUI to set the ThieleSmall parameters) the IPAL achieves a very predictable and
stable electromechanical structure. The actual loudspeaker
will behave as the emulated virtual transducer, regardless to
aging, power compression and parameters drift, thanks to
the closed feedback loop that adaptively aligns the performance of the system to the desired ones.
to the environment condition, overcoming the
physical limitation of traditional sound reinforcement systems.
7 : 4.2. Pressure mode
The Pressure mode relies on the DPC making it possible
to match a specic target pressure response. Being the SPL
output of any acoustic signal derived from the relationship
between the pressure and the acoustical impedance, it’s
straightforward to use a direct measurement of such a
pressure signal to make the system track a reference target
pressure model. Benets in terms of predictability of the
system response and reduction of sensitivity from disturbing effects could be substantially appreciated.
