DM***0
High Efficiency *-Channel Class-D Amplifier Module
for Professional Applications
DM***0 is
a class-D amplifier module delivering up to ***0 W,
ideal for a wide range of applications such as mid
to high power subwoofers, *-way cabinets, stage
monitors or active mixers.
Both power supply and *-channel output
stage are mounted in a single and robust chassis of
the same size of other DM modules, for maximum
scalability of mechanical design for different
products.
Specifically designed DSP boards with
advanced processing, remote control and networking
capabilities are available forDM***0,
to perfectly fit with the amplifier and providing a
complete solution in a compact package.

▶ Premium
Performance
Class-D
technology used in DM modules
is an industry standard
in terms
of quality, reliability, robustness
and attention to detail.
Accurate design of the Pulse Width Modulation block
guarantees maximum
performance, high predictability and immunity
from intermodulation
artifacts.
▶ Powerful
and flexible signal processing tools
Compatible
with third party DSP.
▶ Complete
set of protections
DM modules
are equipped with extensive
protection circuitry: power
limiters, thermal shutdown, short
circuit and overload, clip
limiter.
▶ Compact:
Power
supply, output stage, DSP and connectors
are all included in a single,
compact, lightweight and protected chassis
