General
Power amplifiers have always been heavy, and it's really no wonder, given their large transformers and heat sinks. With the coming of the digital age though, the technology is available to change all that, and that's exactly what Behringer has done with their EPX amplifiers, which are based on the revolutionary switch-mode power supply technology. Such technology means that these amplifiers weigh 40% less than their conventional counterparts, which means no more lugging around heavy transformers!
Europower EPX2800: lightweight and reliable
The EPX2800 and EPX4000 weigh no more than 10.1 kg, which makes transporting them anything but back-breaking work. Perhaps best of all though, is the reliability of the EPX amplifiers. They offer an even tighter bass reproduction than their predecessors, because they can handle high peak powers.
EPX amps: a class of their own
The secret of the impressive power/weight ratio of the EPX series is the use of switch-mode power, combined with class H topology. What that means, is that these amps only use power when necessary, so they're not continuously running on full power. This makes them much more efficient than conventional power amps, not to mention smaller and lighter.
