Conceived and designed by
BEHRINGER Germany
Ultra-light, built on a legacy
Power amps have always been
heavy, mainly because of the massive
transformers and huge banks of capacitors
needed for high-power operation. In fact,
six conventional power amps in a rack can
easily top 250 pounds. The same number
of EPX Series amps come in at just under
134 lbs./61 kg, and they pack all the power
of their conventional counterparts!”
In a class of their own
The secret to the EPX series’ incredible
power-to-weight ratio is their use of a
switching-mode power supply combined
with Class-H topology. Switching-mode
power supplies work on demand. Instead
of constantly working at full power
and dissipating excess power as heat,
they only ramp up the power output
when needed—thousands of times per
second. Considerably more efficient than
traditional power supplies, switching-
mode power supplies are small and light,
yet deliver ample power.
Think of a Class H amp as a car with two
engines (in amps, you call them“rails”).
One engine runs all the time. The other
runs only when musical peaks demand
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.

Power Amps
And just like in today’s hybrid cars, the efficiency
of this dual system is far greater than having one
engine or rail that must operate all the time. EPX
amps don’t waste power. Class H amps don’t waste
power, require much smaller heat sinks and much
lighter power transformers.
Accelerated Transient Response delivers the
knock-out 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, our amps are able to 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.
Instead of operating relatively continuously
like Class AB circuits, Class H amps, which were
first described in NASA technology (U.S. patent
3,319,175), feature rail tracking for effectively
modulating the power supply rails with only the
peaks of the input signal. This technology has
revolutionized pro audio amp designs with its
outstanding performance and efficiency. When
combined with switching-mode power supplies that
replace heavy toroid transformers, our new designs
provide more dynamic punch and, because they are
so much more efficient, run cooler and don’t require
huge, heavy heat sinks.
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 also achieve our goal of
Accelerated Transient Response.
Everything you need, nothing you don’t
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 indicate 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,
1/4" TRS, and unbalanced 1/4" 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 found on the back offers an
array of cool options applicable to both channels.
The Clip Limiter lets you get even more out of
the amplifier without overdriving either it or your
speaker system. Built-in circuitry automatically
senses when the amp is being overdriven into
“clipping” and then momentarily reduces the input
level to avoid clipping distortion. This all happens in
a few thousandths of a second, so it’s an inaudible
way of avoiding audible clipping distortion. Of
course, you can turn the Limiter off if you’re
feeling lucky.
The same panel contains the switches that
allow you to put these amps to work in either
mono, stereo (two-channel mode) or bridge mode,
which is always in mono. A built-in CROSSOVER
switch lets you select the point at which highs and
lows are separated (CH1<100Hz / CH2>100 Hz or
FULLRANGE).
BEHRINGER’s EPX line is built for the working
musician. It’s much easier to transport than a
conventional AB power amp, it packs ample power,
it’s got a built-in crossover and limiter, and it’s built
to last through all the rigors of the road. Plus its light
price tag will leave you with enough cash left over to
acquire more stuff to amplify! Check out an EPX and
find out why BEHRINGER power amps are among
the most popular on Earth.
