EPQ Series ampliers combine serious
output power with high-tech eciency to
create feather-light power amps that will
keep your rig kicking for years to come.
With four stereo models, ranging from
450 to 2,000 Watts, and the four-channel
EPQ304 (4 x 75 Watts) to choose from,
there is an EPQ Series amplier for every
application. And these 1RU and 2RU
amps are only 10.1 inches deep (257 mm),
so they t into virtually any size rack.

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,

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.

This technology has revolutionized pro
audio amp designs with its outstanding
performance and eciency.
When combined with switching-mode
power supplies that do away with
heavy toroid transformers, our new
designs provide more dynamic punch
and, because they are so much more
ecient, run cooler and don’t require
huge, heavy heat sinks.

BEHRINGER didn’t invent this
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 and
indicators of these amps provide all
of your system’s vital signs at a glance.
After pressing the Power Button,
the POWER LED will light to show the
amp is ready for action. All channels have
independent gain dials with SIGNAL
LEDs that light when a signal is present,
as well as clip LEDs to indicate when the
signal is distorted and you need to reduce
the gain.

While all EPQ models accept balanced
XLR and ¼" TRS INPUTs, the EPQ2000
and EPQ1200 also accept unbalanced
RCA connections. Professional locking
speaker outputs are provided to securely
connect to your passive loudspeakers,
plus touch-proof binding posts are
supplied on the EQP1200 and EPQ2000
models. The same panel contains switches
that allow you to put these amps to work
in either mono, stereo or mono bridge
mode. The four-channel EPQ304 can be
operated in quad mono, dual stereo or
dual bridge mode.

EPQ Series Operating Modes

A built-in CROSSOVER switch
(EPQ2000 and EPQ12000 only) allows you
operate in biamp mode, sending low
frequency content to subwoofers via
the CH1 output and mid/high frequency
output to CH2. The crossover frequency is
preset internally at 100 Hz. Additionally,
the EPQ2000 and EPQ12000 models each
feature a built-in, switchable LIMITER for
the ultimate in loudspeaker protection.

Value

BEHRINGER’s new EPQ power amps are
exceptionally light, pack massive power
and are built to withstand the rigors
of the road. With four unique models
to choose from, there’s an EPQ Series
amp that is ideal for your application,
no matter how diverse–plus its light price
tag will leave you with money left over to
acquire more stu to amplify! Check out
