Thanks to Behringer's revolutionary Class-D amplifier technology and internal switch-mode power supplies, the Eurolive B215D loudspeakers provide a much better power-to-weight ratio than competing active speakers. This means that you get all the power without the back-breaking weight. And the sound quality of these lightweight loudspeakers exceeds that of the popular Eurolive B212A and B215A systems.
The Behringer B215D cranks out 550 clean, punchy audio watts, which is impressive for a compact loudspeaker system. The integrated sound processor provides total system control, along with dependable protection of the LF and HF transducers. That's thanks to the built-in active high-pass filter, which virtually eliminates 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.
Intelligent by Design
One of the coolest things about active loudspeakers is the lack of heavy 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, which makes it difficult for a single user to heave all that mass onto the top of a speaker stand. Behringer's B215D's "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, but the overall weight is still 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, thus 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 going into too many details, 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 they have been working for years to perfect their own version with all the benefits of reduced weight and cool running. That's why they invested over a solid year of research time to eliminate pitfalls like quantizing errors and excess dead time, select just the right switching frequency (and other equally tech terms). It's also why they spent an equally long time testing individual components to ensure they could stand up to the rigors of the real world.
When combined with switching-mode power supplies that replace heavy toroid transformers, Behringer's 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 Behringer B215D 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 B215D active loudspeakers will deliver full power and incredible fidelity all night long, with no need for rest cycles.
Instant PA System
With just a single Behringer B215D loudspeaker 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 sound source, place the speaker on a tabletop or stand, and power up. It's just that easy. And if you need more coverage, simply use the convenient LINK OUTPUT XLR connector to add more active loudspeakers.
Stereo Music System
You can even use two Behringer B215D enclosures for stereo playback of your MP3, CD or old-school cassette deck without any additional hardware. Just plug the appropriate stereo "breakout" adapter into your deck's output jack and run the cables to the 1/4" inputs on each loudspeaker. Set the Level and EQ controls the same on both enclosures. Voila, instant party!
Thanks to their trapezoidal design, these cabinets can be laid on their side providing the ideal angle for onstage monitor wedge applications. Hookup is simple, requiring only a single XLR or 1/4" cable from the monitor send on your mixing console and, of course, power. Additional monitors can be chained together via the XLR LINK OUTPUT jack on the rear panel.
Let's face it; the transducers (woofers and tweeters) are the only part of a sound system you actually hear, so Behringer didn't cut any corners. They custom-designed and built their own transducers from scratch. Not only do they wind their own voice coils, they also proceseds the paper pulp into cones and even machined their own backplates.
Low Frequency Response
The Behringer Eurolive B215D was built with extended low frequency handling in mind. With a tuned port, internally braced, injection molded enclosure, each model's custom-designed LF transducer (woofer) really cranks out tight low end. Keep in mind that bass response varies according to LF transducer size, so the larger the speaker, the more bass you will be able to generate.
Accurate Midrange and Treble
Even if your particular application doesn't include booming bass, you'll love the sheer accuracy of these loudspeakers. Over a year of design went into a exponential horn/aluminum dome compression driver combination that could do justice to loud hard rock or dance music -- yet could also satisfy audiophiles with its musical timbre and attention to detail. For spoken word, singing or acoustical instruments, they are un-matched for being able to articulate complex harmonic details. In fact, many customers think it's the most natural-sounding speaker they've ever heard at anywhere near the price.
Processor Controlled Output
Dynamic processing is one of the best ways to maximize output without sacrificing sound quality. The Behringer B215D's built-in circuitry automatically adjusts program content, allowing the loudspeaker to operate at extreme levels. It accomplishes this by reducing bass output slightly as you approach the limit of the transducers. This frees up LF amp and transducer resources, so that higher overall volume can be realized. It's like having a tiny soundman inside each cabinet constantly monitoring and changing output parameters. By making subtle changes to the crossover frequency and the audio content, the system is able to crank out more sound -- without the slightest hint of distortion.
Massive Power to Size Ratio
Cutting-edge technology and high-fidelity speakers are not all it takes to get your message across -- you need power, and lots of it. At the heart of each Behringer Eurolive B215D loudspeaker are two high-current amplifiers with a total output of 550-Watts. They're capable of driving the speakers to their maximum with no distortion -- and without speaker damage, thanks to active internal protection circuits. The result? Massive punch, smooth mids and articulate top-end.
Which Speaker do I Need?
As you've probably noticed, Behringer makes these active loudspeakers in four different woofer sizes. The larger a room's cubic volume, the more energy is required to achieve a given level of bass. In other words, when playing the same tune in a big room versus a small room, big room = less bass; small room = more bass. Start with your application: Is it spoken word in a hotel ballroom? Hard rock in a park? A folk singer or a drum 'n' bass DJ? Loud enough for an 18-year old or loud enough for your grandmother? A huge auditorium or a tiny club? Physics are physics and a 15" low frequency transducer has almost 40% more surface area with which to move air than a 12". A 12" has 30% more area than a 10", and a 10" has 35% more than an 8". So the easiest answer is "Whether to choose one speaker cabinet over another depends on your bass requirements." If you're addressing a small meeting, or demoing the "slice-o-chop-o-vegamatic" at the swap meet or county fair, the B208D might be all the speaker you'll need. But if you're providing disco to the masses at a standing room only nightclub -- or you just need to crank it up louder, then the B215D may be a better choice.
