Electrostatic Discharge (ESD) 6
Electrostatic discharge (ESD) is one of the most signi-
cant 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 pro-
vided with some form of ground conductive or dissipative
ooring.

6 Digimod 3004 PFC4 User Guide 7
7:1.Welcome
Congratulations on your purchase of the Powersoft
DigiMod 3004PFC4 module.
We know you are eager to use the DigiMod 3004PFC4
module, but please take a moment to read this user’s man-
ual and safety instructions. In case you have any questions,
please do not hesitate to contact your dealer or Powersoft.
The DigiMod 3004PFC4 is a four channel amplier mod-
ules specically designed to drive high power loudspeakers.
The DigiMod 3004PFC4 represents an important evolu-
tion in the DigiMod Series family of products: delivering up
to 1000 W on 4 � per channel (2000W on 8 � in mono-
bridged mode), the DigiMod 3004PFC4 reaches a new level
of excellence in terms of power consumption and sonic
performance.
The xed frequency switching mode technology design
guarantees maximum performances, high efciency and
predictability ensuring total immunity from intermodulation
artifacts. The new design of the power supply equipped
with PFC and Smart Rails Management reduces power
consumption and enhances reliability and consistency in
all operating conditions.
The DigiMod 3004PFC4 shares the same compact me-
chanical layout of the other DigiMod Series models guaran-
teeing scalability to existing and future implementations and
is fully compatible with all existing Powersoft DSP solutions
providing a powerful and exible signal processing tools on
board of your loudspeaker.
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 dis-
posal and can normally be recycled.
Rather than just throwing these materials away, please
ensure they are offered for recycling.

Thermal constraints
This device must be correctly heatsinked for proper and
reliable operation: an appropriate external passive heat sink
guarantees by design thermal efciency and reliability.
Proper heatsink planarity is strongly suggested to al-
low thermal transfer from the module’s bottom plate to the
heatsink; a thermal compound may be used, but it is not
strictly necessary.
In order to ensure proper ventilation of the module, rea-
sonable spacing of at least 100 mm must be left between
the frame of the unit and any side component or surface of
the enclosure.
The module has been designed to t into a loudspeaker
cabinet: please refer to FIGURE 1 for proper module placing.
IN FIGURE 1 HEATSINK FINS ARE SET HORIZONTALLY
(WRONG!) ONLY FOR DESCRIPTIVE PURPOSE.
All conguration showed in FIGURE 1 are viable for
proper module placing and cooling. We suggest to posi-
tion the module vertically with respect the ground in order
to take advantage of the chimney effect for ventilation and
heat dissipation.
In FIGURE 1.athe module and the loudspeakers share
the same room into the cabinet. This is the default place-
ment solution: it allows good ventilation because of woofer
diaphragm movement and high air volume; be aware of
magnetic eld interaction: place the module far enough from
loudspeakers magnet in order to prevent fans blockage.
FIGURE 1.bshows the more efcient cooling congura-
tion, even if it is less effective against dust and moisture
that can get into the module. By allowing external air ow,
it is possible to reduce the ns width on the heatsink by
maintaining good cooling performances.
8:1.Heatsink performance
Here we suggest a rule of thumb to calculate the thermal
resistance of the heatsink.
The absolute thermal resistance of the heatsink is the
temperature difference (kelvin or celsius) across its structure
when a unit of heat energy ows through it in unit time (watt).
For seek of simplicity: a heatsink with low thermal resistance
offers high heat dissipation, as well as a low electric resist-
ance allows high current owing through a conductive wire.
In order to dene the maximum allowed thermal resist-
ance for the heatsink let assume the following:
f eas the amp module efciency
f cf as the crest factor of the audio signal
f Wmax as the peak power delivered by the module
f Tamb as the highest ambient temperature
f Tmod as the highest operating temperature
The thermal resistance of the heatsink derives from the fol-
lowing formula:
meaning that the temperature of the bottom plate is always
lower than 75°C if the heatsink has a thermal resistance
better than 0.14°C/W (or 0.14 K/W) with ambient temperature
up to 45 °C.
For example, stating an efciency of 80%, 6 dB crest factor
and 3400 W peak power, the dissipated heat is:
Supposing that the thermal protection of the module (Tmod) is
set at 75°C (167°F) on the bottom plate and stating an ambi-
ent temperature of 45 °C (113°F), the previous example gives:

Electromagnetic Compatibility (EMC) & Safety
9:1.AC MAINS filter
This equipment has been tested and found to be compliant
with regulations listed in “Reference Standard” section.
This equipment is compliant with Class A of CISPR 32. In
a residential environment this equipment may cause radio
interference.
In order to improve the electromagnetic compat-
ibility performance an EMC lter must be inserted
before the AC MAINS plugs on the power supply. An
example of the suggested lter topology is reported below:
9:2.Cabling
Wiring between the amp module and the load may lead
to radio frequency noise. The following guide lines should
be observed:
f reduced cabling length is advisable;
f keep cable pairs as close as possible to each other in
order to minimize the antenna effect;
f design the cabling path far from RF noise source;
f set the cabling for RF noise rejection: shielded or twist-
ed cables are advisable conguration (ref. FIGURE 4);
f place ferrites as close to the module as possible
9:3.Ferrite cores
Reject RF noise from input and output cabling by in-
stalling ferrite shields. Powersoft suggests the FAIR RITE
0431164181, or equivalent.
9:5.Mains Fuse
Mains voltage cable must by protected by an external
Time delay fuse of 10A rating (time lag, Littlefuse Series
215). Replace the fuse with the same type and rating.
Wrap both cables around one side of each ferrite so that
it pass through each ferrite twice (ref. FIGURE 3). Install the
ferrite shield as close as possible to where the cable plugs
into the amplier. Placing the ferrite elsewhere on the cable
noticeably reduces its effectiveness.
9:4.Chassis shielding
If not already present on the product, a full body metal
chassis or a shielding cage will provide best shielding of RF
emission. In order to achieve the highest shielding, minimize
the amount and size of holes or opening in the chassis.

9:6.Earth connection
This device must be powered exclusively by earth
connected mains sockets in electrical networks
compliant to the IEC 364 or similar rules. Is absolutely nec-
essary to verify this fundamental requirement of safety and,
in case of doubt, require an accurate check by a qualied
personal.
Is absolutely necessary to ground this device using the
proper earth connection on the metal frame of the chas-
sis; use M4 nut and bolt with proper split washer – grover
washer – to secure the earth terminal lug.

10:1.1.Main connectors pinout
The following image and tables show the pinout of main
input and output connectors and the SIMM board.
FIGURE 6 shows the default jumpers conguration for
the Bypass connectors. By means of these jumpers it is
possible to change the main gain and enable the DSP and
external circuits.
Gain at +38dB is intended for low level inputs which
need more boost, such as consumer devices; take care
on raising the gain since this involves more noise at output
stages.
DSP and external circuits – such as lters or volume
regulators– can be independently activated by removing
related jumpers on PL1000 for channel 1, PL2000 for chan-
nel 2, PL3000 for channel 3 and PL4000 for channel 4. Both
DSP and external circuits can be layed on a 72-pin SIMM
board which would be plugged into the SO5 Socket; for
more informations about SIMM specications, please con-
tact Powersoft. SIMM board pinout is shown on FIGURE 8.
