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 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.
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 e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 signi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 eciency all the time. And just
like in today’s hybrid cars, the eciency
of this dual system is far greater than
having just one engine or rail that has
to operate continuously.

Accelerated Transient Response
Delivers the Knockout Punch
It takes huge pulses of energy
(current and voltage) to propel a woofer
cone out fast enough to match a bass
beat. That’s called Transient Response
and it’s the holy grail of amp designers.
By carefully selecting transistors with
extremely high slew rates and optimizing
other proprietary parts of our circuitry,
EPX amps can react instantly to even
the most demanding electronic bass
impulses. If the woofers in your PA system
can keep up, your audience will hear a
tighter, crisper, more natural sound.
BEHRINGER didn’t invent Class-H
technology, but our R&D Department
has been working for years to perfect our
own version, creating lightweight amps
that run cool and achieve our goal of
Accelerated Transient Response.
Everything You Need
The simple front panel controls of
these amps give you all of your sound’s
vital signs at a glance. After pressing
the Power Button, the POWER LED will
light when the amp is ready for action.
Both channels have independent gain
dials, as well as CLIP LEDs that notify you
when the signal is distorted and you
need to reduce the gain. There are also
SIGNAL LEDs that light up when a signal
is present at the input.
Panel Discussion
The EPX Series’INPUTs accept
balanced XLR, ¼" TRS, and unbalanced
¼" TS and RCA connections. Take your
pick of professional locking speaker
outputs or touch-proof binding posts to
securely connect speakers.

A panel of switches located on the back
oers an array of cool options applicable to
both channels. The switchable Clip Limiter
lets you get even more out of the amplier
without overdriving either it or your speaker
system. Built-in circuitry automatically
senses when the amp is being overdriven
into “clipping” and instantaneously reduces
the input level just enough to avoid
clipping distortion.
Built-In Crossover
The rear panel also contains a switch
that allows you to put these amps to work
in mono, stereo (two-channel mode)
or bridge mode, which is always mono.
A built-in CROSSOVER switch lets you put
the amp into biamp mode, which sends
low-frequency content (<100 Hz) to the
CH2 Output and the high-frequency
component to CH1 automatically,
no external hardware required.
