Behringer EUROLIVE B212D Active PA Speaker System Description:
Finally, Great-Sounding ActiveLoudspeakers That Won't Break Your Back or Bank Account!
Thanks to our revolutionary Class-Damplifier technology and internal switch-mode power supplies, EUROLIVE D Seriesloudspeakers provide a much better power-to-weight ratio than competing activespeakers. Put simply, you get all the power without the back-breaking weight.
Due to their high-efficiency design, theycrank out some of the cleanest,punchiest audio Watts you've ever heard from acompact loudspeaker system. The integrated sound processor provides totalsystem control, along with dependable protection of the LF and HF transducers,thanks to the built-in active high-pass filter, which virtually eliminatedistortion — even at extreme operating levels. In addition, all four modelsfeature an Ultra-Low Noise (ULN) Mic/Line input with LEVEL control and adedicated 2-band EQ (bass/treble) for easy control.

Intelligent by Design
One ofthe coolest things about active loudspeakers is the lack of back-breaking racksof amps, crossovers and EQs that are often required to make passive speakersystems sound almost as good. But that comes with a trade-off — that extraweight is transferred to the loudspeaker, making it difficult for a single userto heave all that mass onto the top of a speaker stand.
BEHRINGER's D Series' "Intelligent-Design" merges the best featuresof active loudspeakers with significantly lower weight by using switch-modepower supplies and Class-D amplifier topology.
Hidden deep inside each enclosure is the equivalent of an active 2-wayelectronic crossover, graphic EQ, parametric EQ, mic preamp, limiter and twoClass-D power amplifiers, yet overall weight is less than comparableloudspeaker systems! These components work together seamlessly to provideoptimum sound quality — and it all takes place automatically, without youhaving to touch a single knob.
Class D Amplifier Technology Delivers High Power With Low Weight.
Insteadof operating relatively continuously like ClassAB circuits, Class D amps switchon and off thousands of times per second, delivering power only when needed. Inother words, the amplifier is either fully on or fully off , whichsignificantly reduces the power losses in the output devices. This is easy intheory and complex in practice, which is why there are so many different ClassD 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 requirescompensating for a lot of potential problems that can cause audible distortion.BEHRINGER didn't invent Class D technology, but our R&D Department has beenworking for years to perfect our own version with all the benefits of reducedweight and cool running, and none of the drawbacks. That's why we invested overa solid year of research time eliminating pitfalls like quantizing errors andexcess dead time, selecting just the right switching frequency (and otherequally tech-y terms). And why we spent an equally long time testing individualcomponents to ensure they will stand up to the rigors of the real world.
When combined with switching-mode power supplies that replace heavy toroidtransformers, our new designs provide more dynamic punch since the higherswitching frequency reloads the supply's capacitors much faster. And, becausethey are so much more efficient, the D Series runs cooler and doesn't requirehuge, heavy heat sinks. The resulting speakers systems are much lighter, makingthem easy to transport and set up. Our no-compromise design means your D Seriesactive loudspeakers will deliver full power and incredible fidelity all nightlong, with no need for rest cycles.
Instant PA System
Withjust a single D Series loudspeaker system and a microphone or MP3 player, youcan set up an instant sound system. Thanks to the built-in preamp section, youjust connect a dynamic mic and raise and lower the volume with the Levelcontrol. 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 usethe convenient LINK OUTPUT XLR connector to add more active loudspeakers.
Stereo Music System
Youcan even use two D Series enclosures for stereo playback of your MP3, CD orold-skool cassette deck without any additional hardware. Just plug theappropriate stereo "breakout" adapter into your deck's output jackand run the cables to the 1/4" inputs on each loudspeaker. Set the Leveland EQ controls the same on both enclosures. Voilà, instant party!
Marvelous Monitoring
Thanksto their trapezoidal design, these cabinets can be laid on their side providingthe ideal angle for onstage monitor wedge applications. Hookup is simple, requiringonly a single XLR or 1/4" cable from the monitor send on your mixingconsole and, of course, power. Additional monitors can be chained together viathe XLR LINK OUTPUT jack on the rear panel.
Custom-Designed Transducers
Let'sface it; the transducers (woofers and tweeters) are the only part of a soundsystem you actually hear, so we don't cut any corners. While some of ourcompetitors are content to buy off-the-shelf transducers and plug them intotheir boxes, we custom-design and build our transducers from scratch. Not onlydo we wind our own voice coils, we process the paper pulp into cones and evenmachine our own backplates. This enables us to control the quality, andfrankly, make better components, like the long-excursion LF transducers and state-of-the-art1.35" compression drivers we deploy in each and every EUROLIVE enclosure.
Low Frequency Response
TheEUROLIVE D Series was built with extended low frequency handling in mind. Witha tuned port, internally braced, injection molded enclosure, each model'scustom-designed LF transducer (woofer) really cranks out tight low end. Keep inmind that bass response varies according to LF transducer size, so the largerthe speaker, the more bass you will be able to generate.
Accurate Non-Fatiguing Midrange and Treble
Evenif your particular application doesn't include booming bass, you'll love thesheer accuracy of these loudspeakers. Over a year of design went into aexponential horn/aluminum dome compression driver combination that could dojustice to loud hard rock or dance music — yet could also satisfy audiophileswith its musical timbre and attention to detail. For spoken word, singing oracoustical instruments, they are un-matched for being able to articulatecomplex harmonic details. In fact, many customers think it's the mostnatural-sounding speaker they've ever heard at anywhere near the price.
Processor Controlled Output
Dynamicprocessing is one of the best ways to maximize output without sacrificing soundquality. The D Series' built-in circuitry automatically adjusts programcontent, allowing the loudspeaker to operate at extreme levels. It accomplishesthis by reducing bass output slightly as you approach the limit of thetransducers. This frees up LF amp and transducer resources, so that higheroverall volume can be realized. It's like having a tiny soundman inside eachcabinet constantly monitoring and changing output parameters. By making subtlechanges to the crossover frequency and the audio content, the system is able tocrank out more sound — without the slightest hint of distortion.
Massive Power to Size Ratio
Cutting-edgetechnology and high-fidelity speakers are not all it takes to get your messageacross — you need power, and lots of it. At the heart of each EUROLIVE D Seriesloudspeaker 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. Putsimply, they will astound you with their massive punch, smooth mids andarticulate top-end!
