BEHRINGER’s D Series’ “Intelligent-

Design” merges the best features of active 
loudspeakers with signifi cantly lower 
weight by using switch-mode power 
supplies and Class-D amplifi 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 amplifi 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.

Instead of operating relatively 

continuously like Class AB circuits, Class-D 
amps switch on and off  thousands of 
times per second, delivering power 
only when needed. In other words, the 
amplifi er is either fully on or fully off , 
which signifi 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 diff erent Class-D 
designs. Without boring you with terms 
like PWM Generation and Gate Drivers, 
let’s just say that to realize the benefi ts of 
a Class-D design requires compensating 
for a lot of potential problems that can
