EPQ Series amplifiers combine serious 

output power with high-tech efficiency 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 amplifier for every 
application. And these 1RU and 2RU 
amps are only 10.1 inches deep (257 mm), 
so they fit into virtually any size rack. 

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 efficiency. 
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 
efficient, 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.
