Thanks to Behringer's revolutionary Class-D amplifier technology and internal switch-mode power supplies, EUROLIVE D Series loudspeakers provide a much better power-to-weight ratio than competing active speakers. Put simply, you get all the power without the back-breaking weight. And the sound quality of these lightweight loudspeakers exceeds that of Behringer's extremely popular EUROLIVE B212A and B215A systems - plus they've included two 200-Watt models, the B210D (10") and B208D (8") for less demanding applications. Due to their high-efficiency design, they crank out 550/200 of the cleanest, punchiest audio Watts you've ever heard from a compact loudspeaker system. The integrated sound processor provides total system control, along with dependable protection of the LF and HF transducers, thanks to the built-in active high-pass filter, which virtually eliminate distortion - even at extreme operating levels. In addition, all four models feature an Ultra-Low Noise (ULN) Mic/Line input with LEVEL control and a dedicated 2-band EQ (bass/treble) for easy control.

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.

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 thier 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 they've 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 Behringer spent an equally long time testing individual components to ensure they will stand up to the rigors of the real world. When combined with switching-mode power supplies that replace heavy toroid transformers, the new designs provide more dynamic punch since the higher switching frequency reloads the supply's capacitors much faster. And, because they are so much more efficient, the D Series runs cooler and doesn't require huge, heavy heat sinks. The resulting speakers systems are much lighter, making them easy to transport and set up. This no-compromise design means your D Series active loudspeakers will deliver full power and incredible fidelity all night long, with no need for rest cycles.
