Ultra-light, Built on a Legacy
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 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.
