Behringer's EPX2000 Stereo Power Amp 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 affordability will
leave you with enough cash left over to acquire more music gear to amplify!
The simple front panel controls the Behringer EUROPOWER
EXP2000 amp and gives 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.
Power amps have always been heavy, mainly because of the
massive transformers and heat sinks. Behringer's new EPX Series amps are based
on groundbreaking switch-mode technology which eliminates the heavy
transformer. As a result, the amp weighs around 40% less - in fact the EPX2000
is just 22 lbs./10.10 kg, and you can lift it up almost with one finger. Best
of all our super-reliable switch-mode power supply provides an even tighter
bass performance as it can deliver ultra-high peak currents.
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.
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
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).
