Behringer EPQ304 Overview

Ideal for modest live stages, mobile PA systems, and home entertainment systems, the EPQ304 from Behringer is a 4-channel power amplifier that provides up to 75W per channel into four ohms and 50W into eight ohms. With comprehensive protections and ATR tech for enhanced punch and clarity, this amp offers incredible value.

With switchable limiters built into each channel, you never have to worry about sudden peaks damaging your gear or your audience's ears. Detented gain controls ensure precision adjustments for just the right mix. I/O options are flexible, including balanced or unbalanced combo XLR-1/4" TRS inputs and speakON speaker outputs. And with a durable all-steel chassis and built-in rack support, this 1 RU power amp fits neatly into any standard equipment rack.

Accelerated Transient Response Technology
It takes huge pulses of energy (current and voltage) to propel a woofer cone fast enough to match a bass beat. That’s called ATR or Accelerated 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 their circuitry, Behringer's amps react instantly to even the most demanding bass impulses. If the woofers in your PA system can keep up, your audience will hear a tighter, crisper, more natural sound.

Efficient Design
Instead of operating relatively continuously like most power amps, the EPQ304 features 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 do away with heavy toroidal transformers, these new designs provide more dynamic punch and, since they are much more efficient, run cooler and don't require huge, heavy heat sinks.
Sublimely Simple Operation
The front-panel controls and indicators provide your system's vital signs at a glance. After pressing the Power button, the Power LED lights show the amp is ready for action. All channels feature positive-detent Gain controls 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 input signal. Just as elegant as the front, the rear panel is home to the balanced, combo XLR-1/4" input connections as well as the professional locking speaker outputs. The same panel contains the switches that put the channels 1/2 and 3/4 of the EPQ304 in Mono, Stereo (two channel mode), or mono Bridge mode.
Sound Value
The remarkable 4-channel EPQ304 power amp was built for the working musician. It is exceptionally light, packs a massive 300 watts of output power, thanks to our Accelerated Transient Response (ATR) technology and is built rugged enough for life on the road.

Behringer EPQ304 Reviews

Great Amp for the studio

By Stephen
Rated 5 out of 5
Date: 2026-01-04

The Behringer Europower EPQ304 is a great amp.I installed it in my studio and was really impressed with it. I have my rack gear ran thru a behringer CX2310 crossover and connected to this amp.It allows me to run my lows thr 2 channels and my highs thru 2 channels with a active sub seperately connected to the crossover and it is all i need in my studio. Powers my speakers great and is easy to set the gain for each channel.Each channel has a seperate meter for clipping.This is a great amp.Easy to connect and i have had no problems with it.I would recommend it for anyone needing a power amp in your setup.It would be great just to setup in a home stereo.

Works Fine For The Bar I Support

Used This To Replace 2 Dead Crown XTI1002's That Were Frankly Overkill For The Use Case. I Am Using 3 Of The 4 Channels To Drive 6 2 Way Overhead Speakers For A Small Bar Area And Has More Than Enough Power For That Use. As Far As The Fan Noise Goes, I Have This Mounted In A Rack In Closet With 5 Other Amps That All Make Noise Too. With The Door Shut On The Closet You Can't Even Hear It.
