M-Drive
1-Channel high performance amplifier module for subwoofer applications
M-Drive is the most powerful amp module
ever built.
Showing amazing gures in terms of both
output voltage (310 V
bilities (200 A
), it’s able to drive even the
peak
most demanding applications of selfpowered
subwoofers.
Specically designed to fully exploit the
potential of M-Force, the innovative transducer developed by Powersoft, the M-Drive
is able to handle extremely low impedance
loads, which makes it the perfect solution
for any conguration of multiple traditional
transducers.
M-Drive can be equipped with any
Powersoft or third-party DSP solution, and
integrates DPC technology used in both IPAL
and M-Force systems.

Efciency and robustness
Maximize performances, minimize consumption
Patented SRM (Smart Rails Management) technology allows to
maximize the efciency of the system and drastically reducing power
consumption at any load condition.
Complete set of protections
Powerful and exible signal processing tools
Thanks to the compatiblity with all Powersoft DSP solutions, perfor-
mances can be easily tailored to t your deseign with Armonía Pro
Audio Suite™.
Compatible with Powersoft DPC® technology for complete control
over the sonic performance of the whole system regardless of
acoustic load.

The DPC® establishes a
global feedback between the
electrical and the acoustic
domains making system
efcient and reactive to the
environment condition.
The Zero LatencyDSP
performs real-time processing of the differential
pressure control signal in order to adaptively correct the
diaphragm displacement. The DPC sensor measures the
difference in pressure between the front and the rear sides
of the radiating diaphragm and uses this information to
alter the behavior of the transducer, according to the actual
boundary conditions.
Thanks to the rich graphic user interface it is possible to
weight and customize the feedback between the electrical
and the acoustic domains.
