[. . . ] 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 INPUT Page 2 of 5 EUROLIVE B215D EUROLIVE B215D LINK OUTPUT LINK OUTPUT INPUT Output Left Output Right INPUT XENYX 2442FX in the output devices. This is easy in theory and complex in practice, which is why there are so many different Class D designs. [. . . ] Just plug the appropriate stereo "breakout" adapter into your deck's output jack and run the cables to the ¼" inputs on each loudspeaker. Set the Level and EQ controls the same on both enclosures. Marvelous monitoring 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 ¼" 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. Custom-designed transducers Let's face it; the transducers (woofers and tweeters) are the only part of a sound system you actually hear, so we don't cut any corners. While some of our competitors are content to buy off-the-shelf transducers and plug them into their boxes, we custom-design and build our transducers from scratch. Not only do we wind our own voice coils, we process the paper pulp into cones and even machine our own backplates. This enables us to control the quality, Continued on next page B215D/B212D/ B210D/B208D 15"/12"/10"/8" 2-Way Active PA Speaker Page 4 of 5 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 D Series' 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 EUROLIVE D Series loudspeaker are two high-current amplifiers with a total output of 550-Watts for the B212D/B215D and 220-Watts for the B210D/B208D. They're capable of driving the speakers to their maximum with no distortion -- and without speaker damage, thanks to active internal protection circuits. Put simply, they will astound you with their massive punch, smooth mids and articulate top-end!As you've probably noticed, we make these active loudspeakers in four different woofer sizes.
