2.2 Wiring
This device must be powered exclusively by ear th con-
nected mains sockets in electrical networks compliant to
the IEC 364 or similar rules. It is absolutely necessary to verify this
fundamental requirement of safety and, in case of doubt, require
an accurate check by qualied personnel.
POWERSOFT cannot be considered responsible for eventual
damages caused to persons, things or data due to an improper
or missing ground connection.
f Before powering this amplier, verify that the correct voltage
rating is being used.
f Verify that your mains connection is capable of satisfying the
power ratings of the device.
f Do not use this ampliler if the electrical power cord is frayed
or broken.
f Do not remove the cover. Failing to do so will expose you to
potentially dangerous voltage.
f Provide a sectioning breaker between the mains connections
and the amplier. The suggested device is a 16A/250V AC, C
or D curve, 10 kA.
f Switching mode amplier is capable of producing hazardous
output voltages. To avoid electrical shock, do not touch any
exposed speaker wiring while the amplier is operating.
This manual contains important information on operating your
Powersoft amplier correctly and safely. Please read it carefully
before operating your amplier. If you have any questions, con-
tact your Powersoft dealer.
2.3 Speaker damage
Powersof t switching mode ampliers are among the most
powerful professional ampliers available and are capable
of producing much more power than many loudspeakers can handle. It is the user’s responsibility to use speakers suitable to the
amplier and to use them in a sensible way that will not cause
damage.
Powersoft will not be held responsible for damaged speakers.
Consult the speaker manufacturer for power handling recommendations.
Even if you reduce the output volume using the amplier’s
front panel attenuation controls, it is still possible to reach full
output power if the input signal level is high enough.
A single high-power tone can damage high frequency drivers
almost instantaneously, while low frequency drivers can usually
withstand very high, continuous power levels for a few seconds
before they fail. Reduce power immediately if you hear any
speaker “bottoming out”: harsh pops or cracking distor tion that
indicate that the speaker voice coil or diaphragm is striking the
magnet assembly.
Powersof t recommends that you use ampliers in this power
range for more headroom (cleaner sound) rather than for increased volume.

User Guide
5 Welcome
Congratulations on buying a Powersoft M Series amplier!
Powersof t is a leading company in the eld of high efciency
audio power management. The Powersoft Class D technology
has changed the way the world looks at professional audio
amplication: no other amplier’s performance comes close for
applications demanding high power and long term reliability.
Thanks to amazing reductions in heat output and weight, without
sacricing output powers, Powersoft ampliers can be used in an
unlimited range of PA applications such as opera houses, theaters,
churches, cinema, and theme parks.
6 The M Series
M Series ampliers are specically designed for touring and live
applications. The ampliers in this series offer smaller dimensions,
lighter weight and the traditionally amazing sound quality and
reliability of all Powersoft products. M Series ampliers have
power ratings suitable for a vast range of common applications
including 70V/100V distributed line systems.
6.1 More sound and less weight
Switching mode technology based ampliers are highly
efcient, delivering greater power to speakers with reduced heat
dissipation: typical running efciency 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 ampliers which achieve highest
efciency only at full rated power output, Class D efciency is
almost independent of output level. Music has an average power
density of 40% of its peak value; this means that other (nonclass D) ampliers can easily generate 10 times more heat than
Powersof t products for the same sound pressure level.
The units in the M Series are designed to work with lo-Z (from
4 �) and with 70V/100V distributed lines. They can deliver up to
1500 W per channel (at 4 �) or 3000 W in bridge mode on 8 �.
The HDSP+ETH versions of all ampliers in this series allow single
channel processing and remote control capabilities.
Powersof t ampliers deliver crystal-clear highs, and a tight,
well-dened 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 distor tion,
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 M Series’ high performance ratings across the
audio bandwidth.
The M Series offers complete protection against any possible
operation error. Every amplier 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!
7 Installation
7.1 Unpacking
Carefully open the shipping car ton and check for any noticeable
damage; the FIGURE 8 shows the packing view. Every Powersoft
amplier is completely tested and inspected before leaving the
factory and should arrive in pristine condition. In the unlikely event
that you should encounter any damage, please notify the shipping
company immediately. Be sure to save all packing materials for the
carrier’s inspection.
Every M Series amplier box contains the following:
f 1 M Series amplier.
f 1 x AC Mains cord with 3-pin plug 15 A for US or
IEC ‘Schuko’ 16 A for every other nation.
f 1 x User Guide.

7.2 Mounting
All Powersoft ampliers are designed for standard 19” rack
mounting with four front panel holes and two rear-lateral holes. In
order to limit the risk of mechanical damages, ampliers must be
xed to the rack using both frontal as well as rear mounting holes
(see FIGURE 9).
brackets
air flow
mains standard. Damage caused by connecting the amplier to an
improper AC mains voltage is not covered by the warranty.
By using good quality input and speaker cables, the likelihood
of erratic signal behavior is reduced to a minimum. Whether you
make them or buy them, look for good quality wires, connectors
and soldering techniques.
7.5 Grounding
There is no ground switch or terminal on the M Series ampliers.
All shield terminals of input connections are directly connected to
the chassis. This means that the unit’s signal grounding system is
automatic. In order to limit hum and/or interference entering the
signal path, use balanced input connections.
In the interests of safety, the unit MUST always operate with
electrical safety earth connected to the chassis via the dedicated
wire in the 3-wire cable. Never disconnect the ground pin on the
AC mains power cord.

7.3 Cooling
All Powersoft ampliers implement a forced-air cooling system
to maintain low and constant operating temperatures. Drawn by
an internal fan, air enters through the slots in the front panel and
is forced over all components, exiting at the back of the amplier.
Th e amplie r ’s co oling sy s t em feat ures an “in telli gent” var iable-
speed DC fan which is controlled by heat sink temperature sensing
circuits: the fan speed will increase only when the temperature
recorded 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 amplier 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
amplier should dangerously overheat, sensing circuits shut down
all channels until the amplier cools down to a safe operating
temperature. Normal operation is resumed automatically without
the need for user intervention.
Caution regarding heat escape should be exercised when
mounting M Series ampliers. Exhaust cooling air is forced out
through the rear of the chassis (see FIGURE 9); make sure there
is enough space around the back of the amplier for this air to
escape. M Series ampliers can be stacked one on top of the other
due to the efcient cooling system they are equipped with. There
is however a safety limit to be obser ved: in case a rack with closed
back panels is used, leave one rack unit empty every four installed
ampliers to guarantee adequate air ow.
7.4 Operating precautions
Make sure the power switch is off before attempting to make
any input or output connections.
Make sure the AC mains voltage used is within the acceptable
operating voltage range specied in the M Series documentation
(factory selected 115 V / 230 V ±15%), depending on your country
7.6 AC mains connection
The AC Mains connection is made via the IEC type connector
on the back of the amplier. Please make sure your AC mains
power source operates within the voltage limits indicated on this
manual (factory selected 115 V / 230 V ±15%).
Safety warning!
Ground wires must be connected!
Do not use adapters that disable grounding.

8 Connections and Operation
This section provides information on amplier connection and
operation. For optimal amplier performance, it is important to
understand the meaning of the information that each M Series
amplier can provide regarding its status and conguration. This
information is available to the user via front panel indicators as well
as through specic LEDs the back of the unit (for HDSP versions
only). This chapter will break down all the front panel and back
panel functions. The remaining par t of the chapter will explain
how to correctly connect the amplier’s inputs and outputs.
8.1 Front panel air lters access
The blue front panel of all M Series ampliers can be removed
to access the air lters. This is useful when the air lters need to
be cleaned due to dust accumulating and clogging the lters thus
hindering proper air circulation vital for cooling purposes.
