6:4.About the amplifier platform
Powersoft X Series condenses a powerbox box and a
full featured DSP inside a multi-channel power amplier
providing a unique scalable and cost-effective solution suit-
ing any and all applications.
6:4.1.Electric power management
Electric power management is transparent to the user:
worldwide AC acceptance and load balancing are achieved
without any manual setup.
The power supply operates in a wide range of mains
voltage – namely from 85 VAC up to 460 VAC – and suites any
distributing alternating-current electrical power congura-
tion: single-phase, bi-phase or three-phase.
Noticeably versatile, the X Series amplier platform
allows perfozrmance to be maintained even in case of vary-
ing mains voltage: thanks to its advanced load balancing
system, aimed to optimize the power drawn from the mains,
when plugged to a multi-phase power line the system dis-
tributes power requests among all available phase conduc-
tors, so that to minimize any effect of varying mains voltage
on system performance.
The power factor correction – PFC – and the patented
Smart Rails Management – SRM – technologies featuring
the power supply maximize reliability, efciency and further
reduce power consumption.
The renowned reliability of Powersoft’s power supplies
and the fully protected circuit design guarantee high sus-
tained power to any and all of the output channels.
6:4.2.Signal management system
Powersoft X Series amplier platforms embed a com-
plete digital audio signal management system based on
ARM Cortex A-8 processor and TI C6000 DSP platform.
This impressive on-board computing capacity heralds a
new and innovative level of signal processing, providing
non-boolean signal routing and mixing, multi-stage equali-
zation with raised-cosine, IIR and FIR lters, delay up to 4 s
in input processing and 200 ms for time alignment, gain and
polarity adjustment, crossover, peak limiters, TruePower™
limiters and Active DampingControl™.
Cirrus Logic CS 5368 and Analog Devices ADAU 1966
converters perform analog-to-digital and digital-to-analog
conversions respectively, both featuring the Tandem™
architecture which provides 24-bit @ 96 kHz AD/DA conver-
sion (32-bit oating point internal path processing), ensuring
unparalleled transparency and high dynamic range, up to
127 dB.
Four AES3 input and two redundant Dante™ port prove
up to 4 different selectable input sources per channel.
The setup parameters of the Powersoft X Series are fully
integrated into Armonía Pro Audio Suite™ which offers an

intuitive interface for parameter adjustment, a comprehen-
sive control over the digital audio processing and complete
real-time monitoring of the system performance.
The integrated WiFi connection permits the X8 and X4
to be accessed and managed via any smartphone or tablet
through a user interface specically developed for local
monitoring.
6:4.3.Class-D output stage
Even more compact and reliable, X8 and X4 Class-D
output stages deliver high output power and pristine sound,
matching almost any load impedance – starting from 2 Ω
load – and hi-Z distributed lines.
Years of study and engineering of Class-D yield to the
development of innovative features and edge technologies
that improve the efciency and the reliability of Powersoft
ampliers.
The legendary Powersoft Class-D output stage ef-
ciency takes advantage of the back-EMF recycling technol-
ogy, that stores the reactive energy coming back from the
loudspeakers (usually a big danger for linear ampliers) and
uses it as active output power.

Installation 11
11:1.Location
The common installation of the amplier is in rack cabi-
nets: in order to limit the risk of mechanical damages, the
ampliers must be xed to the rack using both frontal and
rear mounting brackets.
Note: Instead of connecting the amplier to the power
grid directly, plug the amplier’s mains connections to a
power distribution panel inside the rack cabinet refer to
Chapter 11:4.AC mains supply for more details.
Install this amplier as far as possible from tuners and
TV sets. An amplier installed in close proximity of such
equipment may experience noise or generic performance
degradation.
11:2.Cooling
Install the amplier in a well-ventilated location: the ven-
tilation openings must not be impeded by any item such as
newspapers, tablecloths, curtains, etc; keep a distance of
at least 50 cm from the front and rear ventilation openings
of the amplier.
All Powersoft ampliers implement a forced-air cooling
system to maintain low and constant operating tempera-
tures. Drawn by the internal fans, air enters from the front
panel and is forced over all components, exiting at the back
of the amplier.
The amplier’s cooling system features “intelligent” var-
iable-speed DC fans which are controlled by the heatsink
temperature sensing circuits: the fans speed will increase
only when the temperature detected by the sensors rises
over carefully predetermined values. This ensures that fan
noise and internal dust accumulation are kept to a strict
minimum.
Should however the amplier be subject to an extreme
thermal load, the fan will force a very large volume of air
through the heat sink. In the extremely rare event that the
11:3.Cleaning
Always use a dry cloth for cleaning the chassis and the
front panel. Air lter cleaning should be scheduled according
to the dust levels in the amplier’s operating environment.
Disconnect the AC main source before
attempting to clean any part of the amplifier
In order to clean the vent lters you need to remove the
front cover: never attempt to open any other part of the unit.
By means of a metric hex key #6, unscrew the two
screws located on the left and right sides of the front panel,
(ref. FIGURE 8) gently lift the cover and remove the lter. You
may use compressed air to remove the dust from lters, or
wash it with clean water: in the latter case ensure that the
lter is dry before reassembly.
amplier should dangerously overheat, sensing circuits
shut down all channels until the amplier cools down to a
safe operating temperature. Normal operation is resumed
automatically without the need for user intervention.
X Series ampliers can be stacked one on top of the other
due to the efcient cooling system they are equipped with.
There is however a safety limit to be observed: in case
a rack with closed back panels is used, leave one rack unit
empty every four installed ampliers to guarantee adequate
air ow.

AC mains connection is provided by means of the eu-
roblock Phoenix PC 5/5-STF1-7,62 connector and ying
plug (Phoenix product ID 1777862). Proper assembly of the
AC mains conductors to the ying plug must respect the
power line conguration.
Take care to connect all the ve conductors to the ying
plug in order to guarantee the proper wire section: recom-
mended wires section is 2,5mm2/13 AWG (ref. TABLE 1).

For X4 Powersoft suggests:
monophase AC (P+N+E): 16 A rating, C or D curve, 10 kA;
triphase AC (3P+N+E): 4x10 A rating, C or D curve, 10 kA.
Before connecting this amplier to the AC mains:
 verify that your mains connection is capable to satisfy
the power ratings of the device;
 verify that a ground connection is available;
 verify that a proper sectioning breaker is available;
 do not use this ampliler if the electrical power cord is
frayed or broken;
 connect all the ve conductors to the ying plug as
shown in the pictures.
11:4.1.Three-phase electric power
Usually, three-phase AC mains encompass four power
conductors plus ground (i.e. totally ve conductors) in a
so called 3P+N+E three phase with neutral conguration.
In some instances neutral connection may lack: on three-
phase systems neutral connection is not even neces-
sary given the capability of the X Series to work in delta
connection.
Each single conductor must be secured to the
PC 5/5-STF1-7,62 ying plug as shown in FIGURE 10.
The following operations can be performed
only by professional or qualified personnel
according to local electrical authorities guidelines.
This device must be powered exclusively by
earth connected mains sockets in electrical
networks compliant to the IEC 364 or similar rules.
Since the main power switch on this unit does not pro-
vides a complete insulation of the equipment from the main
power, you must disconnect the main power source to turn
off all power.
Provide a sectioning breaker between the
mains connections and the amplifier.
The proper device to use depends on mains congura-
tion; for X8 Powersoft suggests:
monophase AC (P+N+E): 32 A rating, C or D curve, 10 kA;
triphase AC (3P+N+E): 4x16 A rating, C or D curve, 10 kA.
11:4.AC mains supply
X Series ampliers offers worldwide AC acceptance and
direct connection to any regional power line conguration.
Powersoft’s legendarily reliable power supply is now suitable
to single-phase, bi-phase or three-phase operation from 85
VAC up to 440 VAC (nominally 100 VAC to 240 VAC ±10% mono-
phase and 173 VAC to 440 VAC ±10% three-phase) without
need of manual selection: true three-phase load balancing
is directly achievable by the unit without any complex load
assignment in the power distribution system design.
