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 power losses from the output devices given off as heat. Less heat means our amps don’t need massive heat sinks, and that means we can make them lighter. Behringer’s no-compromise design means your Eurolive D Series loudspeakers will deliver full power with incredible fidelity all night long, without the need for lengthy rest cycles. When used in conjunction with switching-mode power supplies, which don’t require huge and heavy transformers, our Class-D amplifiers provide tremendous dynamic punch and superior fidelity. The resulting speaker systems are much lighter, making them easy to transport and set up.
