Like its fellow EUROLIVE D Series loudspeakers, the EUROLIVE B215D PA speaker system features Behringer's special Class D amplifier technology and internal switch-mode power supply to provide a much better power-to-weight ratio than other active speakers. To put it simply, you get all the power without the backbreaking weight. The high-efficiency design of the Behringer EUROLIVE B215D speaker system cranks out 550 of the cleanest, punchiest audio watts you've ever heard from a compact PA 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 distortioneven at extreme operating levels. In addition, it features an ultralow-noise mic/line input with LEVEL control and a dedicated 2-band EQ (bass/treble) for easy control. Intelligent by designOne of the coolest things about active loudspeakers is the lack of backbreaking 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&mdash:;t hat 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 EUROLIVE 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 the enclosure is the equivalent of an active two-way electronic crossover, graphic EQ, parametric EQ, mic preamp, limiter, and two Class D power amplifiers, yet the overall weight is less than a comparable loudspeaker system. These components work together seamlessly to provide optimum sound qualityand it all takes place automatically, without you having to touch a single knob.Class D Amplifier Technology delivers high power with low weightInstead of operating relatively continuously like Class A/B 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 their R&D department has been working for years to perfect their own version with all the benefits of reduced weight and cool running, yet without the drawbacks. That's why they 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). It's also why they 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, these 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 loudspeakers run cooler and don't require huge and heavy heat sinks. The resulting speaker systems are much lighter, making them easy to transport and set up. Behringer's no-compromise design means your EUROLIVE B215D active PA speaker will deliver full power and incredible fidelity all night long, with no need for rest cycles.Instant PA systemWith just a single EUROLIVE B215D speaker system and a microphone or MP3 player, you can set up an instant sound system. Thanks to the built-in preamp section, you just connect a dynamic mic and raise and lower the volume with the Level control. Plug in your soun
