3.1 Introduction
Congratulations on buying a Powersoft M Series amplier!
Powersoft is a leading company in the eld of high efciency
audio power management. The Powersoft Class D technology
has changed the way the world looks at professional audio
amplication: no other amplier’s performance comes close for
applications demanding high power and long term reliability.
Thanks to amazing reductions in heat output and weight, without
sacricing output powers, Powersoft ampliers can be used in an
unlimited range of PA applications such as opera houses, theaters,
churches, cinema, and theme parks.
3.2 The M Series
The M Series ampliers are specically designed for touring and live
applications. The ampliers in this series offer smaller dimensions,
lighter weight and the traditionally amazing sound quality and
reliability of all Powersoft products. The M Series ampliers have
power ratings suitable for a vast range of common applications
including 70V/100V distributed line systems.
3.3 More Sound And Less Weight
Class D technology based ampliers are highly efcient, delivering
greater power to speakers with reduced heat dissipation: typical
running efciency 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 ampliers which achieve highest
efciency only at full rated power output, Class D efciency 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) ampliers 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 (from
4 Ω) and with 70V/100V distributed lines. They can deliver up to
1500 W per channel (at 4 Ω) or 3000 W in bridge mode on 8 Ω.
The HDSP+ETH versions of all ampliers in this series allow single
channel processing and remote control capabilities.
Powersoft ampliers deliver crystal-clear highs, and a tight, well-
dened 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 Show Always Goes On
The M Series offers complete protection against any possible
operation error. Every amplier 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!
