BEHRINGER’s D Series’ “Intelligent-
Design” merges the best features of active
loudspeakers with signi cantly lower
weight by using switch-mode power
supplies and Class-D ampli er topology.
Hidden deep inside each enclosure
is the equivalent of an active 2-way
electronic crossover, graphic EQ,
parametric EQ, mic preamp, limiter
and two Class-D power ampli ers, yet
overall weight is less than comparable
loudspeaker systems! These components
work together seamlessly to provide
optimum sound quality — and it all takes
place automatically, without you having to
touch a single knob.
Class-D Ampli er Technology delivers
high power with low weight.
Instead of operating relatively
continuously like Class AB circuits, Class-D
amps switch on and o thousands of
times per second, delivering power
only when needed. In other words, the
ampli er is either fully on or fully o ,
which signi cantly reduces the power
losses in the output devices. This is easy in
theory and complex in practice, which is
why there are so many di erent Class-D
designs. Without boring you with terms
like PWM Generation and Gate Drivers,
let’s just say that to realize the bene ts of
a Class-D design requires compensating
for a lot of potential problems that can
