Our 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 and EPX4000 are just 22.3 lbs (10.1 kg) each, so you can practically lift them 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. In a Class of Their Own The secret to the EPX Series' incredible power-to-weight ratio is the use of a switch-mode power supply combined with Class-H topology. Because they work on demand, instead of operating continuously at full power, switch-mode power supplies are much more efficient than traditional power supplies. And since they don't require the massive transformers and heat sinks typically found in conventional power amps, they are significantly smaller and lighter, yet still deliver ample power. Think of a Class-H amp as being similar to a car with two engines (in amps, we call them "rails"). One engine runs all the time. The other runs only when musical peaks demand the extra power output. An EPX Class-H amp only generates a fraction more power than is immediately needed, while the output stage operates at its maximum efficiency all the time. And just like in today's hybrid cars, the efficiency of this dual system is far greater than having just one engine or rail that has to operate continuously. Continued on next page
