Power amps have always been 

heavy, mainly because of their 
massive transformers and heat sinks. 
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 
fi nger. 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.

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 effi

  cient 

than traditional power supplies. 
And since they don’t require the massive 
transformers and heat sinks typically 
found in conventional power amps, 
they are signifi cantly 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 effi

  ciency all the time. And just 

like in today’s hybrid cars, the effi

  ciency 

of this dual system is far greater than 
having just one engine or rail that has to 
operate continuously.
