11 Installation
11 : 1.Location
The common installation of the amplifier is in rack cabinets: in order to limit the risk of mechanical damages, the
amplifiers must be fixed to the rack using both frontal and
rear mounting brackets.
Note: Instead of connecting the amplifier to the power
grid directly, plug the amplifier’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 amplifier as far as possible from tuners and
TV sets. An amplifier installed in close proximity of such
equipment may experience noise or generic performance
degradation.
amplifier should dangerously overheat, sensing circuits
shut down all channels until the amplifier cools down to a
safe operating temperature. Normal operation is resumed
automatically without the need for user intervention.
X Series amplifiers can be stacked one on top of the other
due to the efficient 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 amplifiers to guarantee adequate
air flow.

FIGURE 7: Mounting brackets and air flow direction.
11 : 2.Cooling
Install the amplifier in a well-ventilated location: the ventilation 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 amplifier.
All Powersoft amplifiers implement a forced-air cooling
system to maintain low and constant operating temperatures. Drawn by the internal fans, air enters from the front
panel and is forced over all components, exiting at the back
of the amplifier.
The amplifier’s cooling system features “intelligent” variable-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 amplifier 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 filter cleaning should be scheduled according
to the dust levels in the amplifier’s operating environment.
Disconnect the AC main source before
attempting to clean any part of the amplifier
In order to clean the vent filters 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 filter. You
may use compressed air to remove the dust from filters, or
wash it with clean water: in the latter case ensure that the
filter is dry before reassembly.

11 : 4.AC mains supply
X Series amplifiers offers worldwide AC acceptance and
direct connection to any regional power line configuration.
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% monophase 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.
For X4 Powersoft suggests:
monophase AC (P+N+E): 16 A rating, C or D curve, 10 kA;
triphase AC (3P+N+E): 4 x 10 A rating, C or D curve, 10 kA.
Before connecting this amplifier to the AC mains:
ffverify that your mains connection is capable to satisfy
the power ratings of the device;
ffverify that a ground connection is available;
ffverify that a proper sectioning breaker is available;
ffdo not use this amplilfier if the electrical power cord is
frayed or broken;
ffconnect all the five conductors to the flying plug as
shown in the pictures.
NOTE: The following pictures and instructions refer to
the European CENELEC standards April 2004 (IEC 60446)

TABLE 2: Color code for conductors identification.
The following operations can be performed
only by professional or qualified personnel
according to local electrical authorities guidelines.
11 : 4.1. Three-phase electric power
Usually, three-phase AC mains encompass four power
conductors plus ground (i.e. totally five conductors) in a
so called 3P+N+E three phase with neutral configuration.
In some instances neutral connection may lack: on threephase systems neutral connection is not even necessary 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 flying plug as shown in FIGURE 10.
Since the main power switch on this unit does not provides 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 configuration; for X8 Powersoft suggests:
monophase AC (P+N+E): 32 A rating, C or D curve, 10 kA;
triphase AC (3P+N+E): 4 x 16 A rating, C or D curve, 10 kA.

FIGURE 10: Three-phase connection.
11 : 4.2. Bi-phase electric power
X Series amplifier platforms can accept bi-phase AC
mains in the configurations 2P+E balanced two phase without neutral (on bi-phase systems neutral connection is not
even necessary).
Power conductors must be secured to the
PC 5/5-STF1-7,62 flying plug as shown in FIGURE 11. Take
care to connect all the five conductors to the flying plug as
shown in the pictures in order to guarantee the proper wire
section. Bridge the phase conductors at the connecting
terminals of the mains’ sectioning breaker.
11 : 4.4. AC MAINS plug and shell
Take care to properly lock each power cord wire to the
flying connector Phoenix PC 5/5-STF1-7,62.
Insert and lock the flying connector into the shell provided by Powersoft (ref. FIGURE 14).
The shell is meant for safe handling of the mains
power connector and must always be used.
Once properly assembled, take care to lock the mains
connector to the amplifier plug: shock and vibration may
cause the unintentional disconnection of the AC main connector if not properly secured to the device.
FIGURE 11: Bi-phase connection.
11 : 4.3. Single-phase electric power
P+N+E, unbalanced single phase with neutral is the
usual configuration for signle-phase AC mains.
Power conductors must be secured to the
PC 5/5-STF1-7,62 flying plug as shown in FIGURE 12. Take
care to connect all the five conductors to the flying plug as
shown in the pictures in order to guarantee the proper wire
section. Bridge the phase conductors at the connecting
terminals of the mains’ sectioning breaker.

Output terminals are hazardous: wiring connection
to these terminals require installation by an instructed person and the use of ready made leads.
Take care to secure the output terminal before switching
the device on.
To avoid electrical shock, do not touch any exposed
speaker wiring while the amplifier is operating.
X8. The X8 amplifier platform provides four Neutrik
NL4MD speakON output connectors (one per channel pair).
FIGURE 20: X8 Loudspeaker connectors.
In order to increase the power’s supply energy storage
efficiency, signals coming from each channel pairs are polarity reversed, one with respect to the other within the pair,
when entering the amplifier. This ensures a symmetrical use
of the voltage rails: if, for example, both channels’ 1 and 2
input signals are going through a peak at the same time,
channel 1’s energy will come from the positive voltage rails
while channel 2, whose polarity is reversed with respect to
channel 1, will be fed energy from the negative voltage rails.
In this manner, the power supply will work symmetrically,
with one channel catered by the positive rails and the other
by the symmetrical negative rails. Channel 2’s signal will be
polarity reversed once more at the output connectors to
ensure that both channels output with the same polarity as
their corresponding input signals.

14 : 3.2. IP addressing
14 : 3.Wired connectivity
By means of the two etherCON ports on the rear panel of
the X8 and X4 amplifier platforms, it is possible to connect
the X Series to a Fast Ethernet or Gigabit Ethernet LAN.
14 : 3.1. Network topologies
X Series amplifier platforms support linear daisy-chain,
star and loop network topologies; in a daisy-chained network the PC with Armonía Pro Audio Suite™ must always
be at one end of the chain.
Be aware that daisy-chaining does not guarantee reliability in production environment, since any fault may yield
to network sectioning and lost of system control.
When efficiency and reliability are paramount, a redundant network topology is advisable; refer to Chapter 14 : 4.1.
Redundant network configuration for more details.
In order to exploit the Dante™ features, star and open
daisy-chain network topology are allowed; for more info
about unsupported configurations refer to Chapter 14 : 4.2.
Dante™ unsupported network configurations.
A
Factory default network settings are DHCP/AutoIP, in
order for the amplifier platform to self-configure when connected to an existing LAN or PC. Fixed IP policy can also
be adopted and configured through Armonía Pro Audio
Suite™.
14 : 3.2.1. DHCP
When the data cable is connected the X Series begins
DHCP handshaking. If a DHCP server is present on the
network, the unit is ready to be remotely controlled.
14 : 3.2.2. AutoIP
Taking advantage of the Zero-configuration networking
methodology – Zeroconf –, X Series achieves true plugand-play networking with PCs and LANs.
If a DHCP server is not active within the network, the
amplifier platform initiates a stateless address auto-configuration: it self assigns a local numeric network address
(of the type 169.254.x.y – 172.31.*.* for the secondary
network if present – with a subnet mask 255.255.0.0) and
automatically distributes and resolves the hostnames of
networked devices.
14 : 3.2.3. Static IP
X Series can be set up with a static IP (or any other IP
policy) by means of Armonía Pro Audio Suite™. In order to
set up the IP address please follow these steps.

14 : 3.2.4. IP Addressing troubleshooting
When connecting the X Series to a network environment
it may happen that Armonía Pro Audio Suite™ does not
discover or import the amplifier.
Usually this is a problem of IP addressing: both Armonia
and the X Series must belong to the same subnet. If a DHCP
server is present on the network and a X Series amplifier
platform is in AUTO IP, networking may become unstable.
As a rule of thumb, switch on the DHCP
server before connecting the amplifiers.

14 : 4.1. Redundant network configuration
Audio networking requires high availability since it is
involved in mission-critical operations, for example in a
live sound environment. Data path redundancy acts as a
instant-response backup system to protect the system
against possible cable disconnections or device and signal
failures.
Dante Redundancy can be set up and used between any
supporting Dante-enabled audio equipment: it works by using two completely independent and separate networks, the
Primary Network and the Secondary Network.
To setup and use Dante Redundancy, connect the
X Series amplifier platform and other redundant Danteenabled audio equipment using duplicate Gigabit switches
and Ethernet cables as shown in FIGURE 27. Connect your
PC or Mac running Dante Virtual Soundcard and Dante
Controller, and other non-redundant Dante-enabled audio
equipment to the Primary Network.

15 : 3.Signal routing and DSP architecture
15 : 3.1. Signal processing
Signal processing on Powersoft X Series amplifier platforms accomplishes multiple functions that affect the audio
signal before power amplification.
The X Series embeds classic tools for loudspeaker system management: the close integration of the DSP module
with the power supply and the output stages offers fine parameters adjustment and unrivaled performances in output
power control.
Digital signal processing in X Series can be performed
on many stages of the signal path: the main adjustements
include gain, polarity, delay and signal equalization; some
processing are related to particular stages, such as limiting
and damping control that are present on the
output section only, or input priority assignment in the input section.
15 : 3.1.1. Gain
Gain control allows level adjustment. For
example, in the input stage the gain control
is meant to compensate the signal level
among different sources; on output stage,
the gain control on each output channel
provides output level adjustment.
15 : 3.1.2. Polarity
The polarity switch, flips the polarity of
a signal.
15 : 3.1.3. Delay
The delay control adds time lag on signal path. This
control can be used for different scopes, such as for compensating the signal delay among different sources or time
align clusters of loudspeakers and line arrays.
15 : 3.1.4. Equalization and crossover
Signal equalization provides control over the tonal spectrum of the signal. Equalization can be used to adjust the
speaker cabinet response, in order to create the desired sound
and achieve proper loudspeakers-to-environment matching.
FIGURE 31: Speaker equalizer.
15 : 3.1.5. Limiting
Limiters prevent signals from exceed a certain defined
level (peak or rms, voltage, current or power). Limiting is
meant to avoid output stage overload and protect the loudspeakers from damages caused by excessive excursion or
overheating.
FIGURE 30: Advanced equalizer.
Crossovering refers to splitting the output signal in frequency bands, such as Highs, Mids, and Lows, when the
separate bands are individually amplified and sent to speakers
matching the desired frequency range (multi-way speakers).
FIGURE 32: Limiter.
15 : 3.1.6. Active damping control
FIGURE 34: Output equalizer.
By means of the realtime adjustment of the output
impedance, X Series can compensate cable loss and load
variation, in order for the amplifier to maintain greater control
over the movement of the speaker cone, as well as shaping
the transient response in the low-end band.
This unique and patented feature relies on a “virtual”
output resistor that can have either positive or negative
value to compensate cabling resistance and load variations.
X series implements parametric EQs in three stages along
the signal path per each channel. Furthermore, thanks to the
Advanced group feature of Armonía Pro Audio Suite™, it is
possible to group many speakers (even on different amplifiers) and add an overall equalization.
The number of available filters depends on the stage
they are applied. X Series DSP provides the following filters
type:
ffPeaking
ffRaised cosine
ffAsymmetric rised cosine
ffLow/High Shelving
ffLow/High pass
ffBand stop (notch)

15 : 4.1. Input source selection
Click on the Input section (FIGURE 35 #1) to access the
input source selection interface.
The input section allows you to manage input gain and
delay of analog and digital sources, in order to compensate
transmission latency and levels.
Furthermore the X Series implements a backup policy
aimed to improve reliability against signal fault. By assigning a bus priority to the four different input sources – analog,
AES3 and two Dante™ streams– per channel, the system is
able to automatically switch to a reliable input connection in
case of any signal fault.
The leftmost source has the highest priority: click and
drag to the left the input section in order to rise its priority.
20 | X Series | User guide
FIGURE 36: Input source selection.
Three different backup policies can be selected:
ffmanual – switching of the input source is demanded
to the user;
ffdigital validity – in case of no signal presence or corrupted digital stream on a digital source, the system
will automatically switch the input to the source with
lower priority;
15 : 4.4. Speaker processing
The speaker processing stage is designed to offer effective tools for loudspeaker performance optimization. It
implements FIR and IIR full parametric filters.
Speaker processing has been designed to manage the
configuration presets for multi-way systems; the fine tuning
of each single way’s performance is achieved by the output
processing stage.
fftone detection – the system senses the presence of a
pilot tone and tests its level and frequency: in case of
any misalignment, the system will automatically switch
the input to the source with lower priority where the
pilot tone is present.
15 : 4.2. Matrix
The innovative routing engine of X Series allows any
input to be routed to any output. The Matrix implements a
non-boolean rooting architecture allowing free channel assignment and level adjustment, providing a versatile tool for
matching the input configuration to any loudspeakers setup.
FIGURE 39: Speaker equalization.
15 : 4.5. Speaker routing
FIGURE 38: Matrix.
15 : 4.3. Advanced processing
The speaker routing stage (FIGURE 35 #6) aims to suit
the configuration of multi-way loudspeakers: once properly
grouped, the output channels are presented to the matrix
as speakers – a single row representing a speaker (actually group of ways) – allowing a high grade of granularity in
signal processing.
Routing of the signals entering the speaker routing stage
can be made only on adiacent output connectors, i.e. you
can choose to group the output channels 3 and 4, but you
can not group channel 3 and 5.
In order to group the output channels simply drag a
selection over the output channels on the right column
and press apply. The left column will show the label of the
speaker corresponding to the groups (loudspeakers) you
create.
The advanced section of the X8 allows you to optimize
levels and shape the sound of the input signals. Gain and
polarity adjustment, asymmetric raised-cosine full parametric filters, delay and mute are available on each channel
routed to the speaker section (see below).
FIGURE 40: Speaker routing.
15 : 4.6. Output processing
FIGURE 37: Input processing.
The output processing stage (FIGURE 35 #5) allows fine
tuning of output signals, aiming to optimize power delivering

routing
In order to optimize the performance of the sound reinforcement system, the X Series provides a loudspeaker
management system that allows complete control over the
performance of the loudspeakers configuration.
Once the loudspeaker layout has been defined, we
suggest a bottom-up configuration procedure that starts
from the configuration of the transducers layout and raises
toward the input selection and the definition of the backup
policy.
Shortly, the main steps to follow are:
1. Load the loudspeaker presets or manually configure
the loudspeaker layout (grouping output channels,
crossovering, limiting, speaker processing, etc.).
Input
Processing
2. Define the routing path and the levels of the signals
from the input channels to the active output channels
(matrix).
3. Select the signal source from the input connections
and define the backup policy (input source selection).

X Series allows fine granularity in managing limiters, frequency response, gain, polarity, etc. of each way of a multyway loudspeaker through the output processing stage;
furthermore, when a group of ways are grouped by means
of the speaker routing stage, the X Series provides a tool for
tuning the behavior of the entire multi-way loudspeaker via
the speaker equalization stage.
Once the loudspeaker layout has been defined by
means of the speaker routing tool, the matrix will show only
the actual loudspeakers layout allowing to proper mix and
route the input signal. For example, stating the following
configuration for a X8 (ref. FIGURE 43):

FIGURE 41: Output processing.
ffoutput 1+2+3 as the left three-way loudspeaker
ffoutput 4+5+6 as the right three-way loudspeaker

Each way is driven independently: the crossover allows
to feed the transducers with the right signal bandwidth, limiting as well as damping control can be configured for each
output signal (transducer), and finally you can create the
overall equalization of each single multi-way loudspeaker.
15 : 5.2. Routing path and levels
FIGURE 43: Example: X8 driving three multy-way loudspeakers.
Proceeding backward to the input, the matrix allows to
manage signal routing and mixing suiting the actual loudspeakers layout. In the example of FIGURE 43, speakers A,
B and C becomes the output channels of the matrix, where
you can properly mix and route the input signals.
15 : 5.3. Signal source and processing
The input selection stages add further degrees of
freedom in setting system performance with regards to the
venue and configuring the backup policy for signal redundancy and safe operating.

System and signal protections
Fault protections are systems designed to protect people from severe or fatal electric shocks and avoid severe
damages on the amplifier or the loudspeakers in case of
electrical parameters out of scaling or critical changes in
environmental conditions.
The architecture of Powersoft’s amplifiers encompass
several protection mechanisms triggered by harmful signal and temperature. Protection systems and triggers are
independently implemented in the power supply section
(power supply protection) and the amplifier section (amplifier protections) in order to minimize system damages and
maximize efficiency.
16 not switch off but neither signal processing nor fan cooling
are active. In these conditions, while the temperature slowly
decreases, the rails voltage rises: when the rails voltage
reaches ±33V, the amplifiers section switch on again. If
cooling is not effective, the system may start oscillate.
16 : 2.Amplifier protections
Amplifier protections are triggered by audio signal current and voltage – by comparing input and output – and
thermal feedback.
16 : 2.1. Harmful signal protections
16 : 1.Power supply protections
Power supply protections aim to isolate a faulty section
in electrical power system from the rest of the device in
order to prevent the propagation of the fault and limit device
damages.
16 : 1.1. Primary AC mains overcurrent protection
AC main overcurrent are filtered by time-lag fuses (also
known as time-delay or slow blow-fuse): 20 A time-lag fuses
and 16 A time-lag fuses are used on X8 and X4 respectivelly.
The purpose of the time lag fuse is to allow the supply in
electricity for a short time before the fuse actually blows. If
the time-lag fuse blows out the amplifier switch off: replace
the fuse with a proper time-lag fuse in order to restore the
full functionality of the amplifier.
16 : 1.2. Primary AC mains overvoltage protection
AC mains overvoltage threshold is set to 510 Vrms. If the
AC mains voltage exceeds 510 Vrms the power supply stop
working; the device does not turn completely off but falls in
a “sleeping” mode: the power supply turns on again when
the AC mains voltage drops down.
AC mains overvoltage are well tolerated by the power
supply: no damages can be caused to the system even in
case of severe overvoltage up to 510 Vrms.
16 : 1.3. Primary thermal protection
The working temperature of the power supply controls
the fans speed and the rails voltage. In very harsh conditions, if the fans are unable to maintain the overall temperature into the operating range and components tolerances,
the primary hardware thermal protection starts lowering the
rails voltage in order to lower the system heat.
The process is auto-adaptive and aims to maintain
the system up even in heavy thermal condition. If the rails
voltage drops down to ±33 V the system shut down the
amplifier section, the power supply still running. This may
happen rarely, even in harsh conditions: the amplifier does
24 | X Series | User guide
Bad signals can cause amplifier and loudspeakers
damages. In order to limit damages, harmful signal triggers
specific protections.
16 : 2.2. Output short circuit
If the load impedance is too low or the loudspeaker line
has a short circuit (because of voice coil damages, wires
short circuit, improper wiring, etc), the amplifier output current rises to harmful values.
When the output current exceeds 130 A, the system shut
down the amplifier section, the power supply still working.
After 2 seconds the system tryes to switch on the amplifier
section: if the short circuit still persists, the current rises and
the amplifier is switched off again. The system toggles the
amplifiers on and off every 2 seconds until the short circuit
is removed.
16 : 2.3. High frequency stationary loud signals
High frequency stationary loud signals, like steady sinusoid signals – improperly referred as continuous signals – tend
to stress the amplifier section as well as the loudspeakers
voice coils.
When a high frequency stationary loud signals is feed
into the amplifier the system limits its mean current depending on its level and frequency. The process is auto adaptive
and frequency driven: at higher frequency the limiter acts
faster.
16 : 2.4. DC fault protection
In order to protect your speakers from mechanical
damage caused by a DC signal coming from the amplifier’s output, a DC detection circuit is placed between the
amplifier’s output stage and power supply. If a DC signal or
excessive subsonic energy appears at a channel output an
instantaneous protection circuit will mute the compromised
channel pair.

products to Powersoft for repair. In the latter case, before
shipping, you are kindly asked to follow step by step the
procedure described below: Obtain the “Defect Report
Form” by contacting our Customer Care Department
via email: service@powersoft.it or download the
“Defect Report Form” from Powersoft’s website
(http://www.powersoft-audio.com/en/support/service).
Fill out one “Defect Report form” for each returned
item (the form is an editable tab guided document) and
save as your name, amp model and serial Number (for
example: distributornamek10sn17345.doc) providing all
required information except the RMA code/s and send it to
service@powersoft.it for Powersoft approval.
In case of defect reports approved by the Powersoft
Customer Service Representative you will receive an RMA
authorization code (one RMA code for each returning device). Upon receiving the RMA code you must package the
unit and attach the RMA code outside the pack, protected
in a waterproof transparent envelope so it is clearly visible.
All returning items must be shipped to the following
address:
Powersoft
Via Enrico Conti, 13-15
50018 Scandicci (FI) Italy
In case of shipment from countries NOT belonging to the
European Community make sure you have also followed the
instructions described in the document available for download at the TEMPORARY EXPORTATION / IMPORTATION
PROCEDURE link at http://www.powersoft-audio.com/en/
support/service.
Thank you for your understanding and cooperation and
continued support as we work to improve our partnership.
