Intelligent by design

One of the coolest things about active loudspeakers is the lack of back-breaking racks of amps, crossovers and EQs that are often required to make passive speaker systems sound almost as good. But that comes with a trade-off — that extra weight is transferred to the loudspeaker, making it difficult for a single user to heave all that mass onto the top of a speaker stand.

BEHRINGER’s D Series’“Intelligent- Design” merges the best features of active loudspeakers with significantly lower weight

by using switch-mode power supplies and Class-D amplifier 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 amplifiers, 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 Amplifier Technology delivers high power with low weight.

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 amplifier is either fully on or fully off, which significantly reduces the power losses

in the output devices. This is easy in theory and complex in practice, which is why there are so many different Class D designs. Without boring you with terms like PWM Generation and Gate Drivers, let’s just say that to realize the benefits of a Class D design requires compensating for a lot of potential problems that can cause audible distortion. BEHRINGER didn’t invent Class D technology, but our R&D Department has been working

for years to perfect our own version with all the benefits of reduced weight and cool running, and none of the drawbacks. That’s why we invested over a solid year of research time eliminating pitfalls like quantizing errors and excess dead time, selecting just the right switching frequency (and other equally tech-y terms). And why we spent an equally long time testing individual components to ensure they will stand up to the rigors of the real world.
