the new models of the dpa
8000 series are based on highly
efficient class d platforms and
offer in addition to outstanding
audio performance features such
as integrated automatic break-
down switchover, integrated
electronics for the connection of
multiple loudspeaker lines per
amplifier channel, an additional
audio input, etc.
The Promatrix 8000 system, to
which the DPA 8000 amplifiers
also belong, sets new standards in
the integration of event, information
and evacuation sound reinforcement.
In the development of the DPA
8000 series, the emphasis was
upon the following primary characte-
ristics: smaller dimensions coupled
with greater power, lower power
consumption, higher integration
of functions, and better audio per-
formance. The outcome is a series
of models that meet the highest
demands of modern sound reinforce-
ment systems including evacuation
conformity. With a signal-to-noise
ratio of over 102 dB, the amplifiers
can be used without compromise
for pro sound applications.
Thanks to the permanent integrated
supervision, faults not only in the
amplifiers themselves but also in
the loudspeaker lines connected
are detected and reported imme-
diately. For the supervision of the
loudspeaker lines, a choice is offered
of various methods, which can be
used singly or in combination.
The total power of 500 W in two
rack units is achieved with minimal
power dissipation, which means
savings, too, on external air condi-
tioning.
Each of the amplifiers possesses
an additional audio input for the
playing of background music or
use as an emergency input. For the
connection of multiple loudspeaker
lines to a single amplifier channel,
the control electronics are already
integrated into the amplifier and
can be extended through the DCS
400 modular system.
It goes without saying that power
can be drawn either from the
mains or a battery and that all
devices offer power up current
limiting as well as additional protec-
tive circuitry.
