5 Welcome

Congratulations on buying a Powersoft M Series amplifier!
Powersoft is a leading company in the field of high efficiency
audio power management. The Powersoft Class D technology
has changed the way the world looks at professional audio
amplification: no other amplifier's performance comes close for
applications demanding high power and long term reliability.
Thanks to amazing reductions in heat output and weight,
without sacrificing output powers, Powersoft amplifiers 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 amplifiers are specifically designed for touring and live
applications. The amplifiers in this series offer smaller dimensions,
lighter weight and the traditionally amazing sound quality and
reliability of all Powersoft products. M Series amplifiers 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 amplifiers are highly
efficient, delivering greater power to speakers with reduced heat
dissipation: typical running efficiency 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 amplifiers which achieve highest
efficiency only at full rated power output, Class D efficiency is
almost independent of output level. Music has an average power
density of 40% of its peak value; this means that other (non-
Class D) amplifiers can easily generate 10 times more heat than
Powersoft products for the same sound pressure level.
The units in the M Series are designed to work with lo-Z
(starting from 4 �) and with 70V/100V distributed lines. They
can deliver up to 1500 W @ 4 � per channel or 3000 W in
bridge mode on 8 �. The HDSP+ETH versions of all amplifiers
in this series allow single channel processing and remote control
capabilities.
Powersoft amplifiers deliver crystal-clear highs, and a tight,
well-defined 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 distortion,
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 amplifier 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!

7.1 Unpacking

The FIGURE 8 shows the packing view. Every Powersoft
amplifier 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 amplifier box contains the following:
f 1 M Series amplifier.
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.
