Power amps have always been heavy, mainly because of their massive transformers and heat sinks. Behringer's new EPX Series amps are based on groundbreaking switch-mode power supply technology, which eliminates the heavy transformer. As a result, these amps weigh about 40% less than their conventional counterparts. In fact, the EPX2800 is 22.3 lbs (10.1 kg) each, so you can practically lift it with just one finger. Best of all, EPX Series amps are super-reliable and provide even tighter bass performance than their predecessors, since they can deliver ultra-high peak currents on demand.
