Behringer Eurolive B210D-WH Powered Speaker

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 our 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 we 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 we 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, our 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. Our 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.
