M Series

The Powersoft M Series is a range of 2-channel and 4-channel amplifiers designed to meet the stringent requirements of professional users in both sound reinforcement and fixed installation applications. The M Series represents a superb value from a premium brand with unparalleled efficiency, good for the environment and easy on the power bill. The size and weight is an absolute minimum thanks to the 1 U standard and the reduced depth of the equipment.

Designed by the R&D team at Powersoft, the M Series is exclusively built in Italy with all of its internal components being selected for both their quality and their proven durebility even under extreme conditions.

Each part of the M Series amplifier is pre-tested, and then once assembled the finished amplifier receives a rigarous 48 hour burn-in before finally being tested on a sophisticated test system (also designed and produced by Powersoft) to ensure the ultimate in quality control.

Powersoft's bridgeable switch mode fixed frequency class D patented outputs provide extremely high audio quality, an excellent damping factor and cooler circuits. This makes the output stage much more stable and results in a longer amplifier life.

When M Series is ordered with the DSP+ETH option, DSP modules hidden inside to prevent tampering with system settings and Ethernet connectivity is added. This allows control and configuration via Powersoft's innovative Armonía Pro Audio Suite™ control software.
M Series models can also be used to power constant voltage 70V and 100V lines without the need for external transformers.
