Behringer EPX4000 4000W Lightweight Stereo Power Amp w/ATR

Ultra-light, Built on a Legacy
Power amps have always been heavy, mainly because of their massive transformers and heat sinks. Our new EPX Series amps are based on groundbreaking switch-mode power supply technology, which eliminates the heavy transformer. As a result, these amps weigh about 40% less than their conventional counterparts. In fact, the EPX4000 is just 22.3 lbs , so you can practically lift it with just one finger. Best of all, EPX Series amps are super-reliable and provide even tighter bass performance than their predecessors, since they can deliver ultra-high peak currents on demand.

In a Class of Their Own
The secret to the EPX Series' incredible power-to-weight ratio is the use of a switch-mode power supply combined with Class-H topology. Because they work on demand, instead of operating continuously at full power, switch-mode power supplies are much more efficient than traditional power supplies. And since they don’t require the massive transformers and heat sinks typically found in conventional power amps, they are significantly smaller and lighter, yet still deliver ample power.

Think of a Class-H amp as being similar to a car with two engines (in amps, we call them "rails"). One engine runs all the time. The other runs only when musical peaks demand the 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 just one engine or rail that has to operate continuously.

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, EPX amps can 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.

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 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 notify you 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 located on the back offers an array of cool options applicable to both channels. The switchable 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 instantaneously reduces the input level just enough to avoid clipping distortion.

Built-In Crossover
The rear panel also contains a switch that allows you to put these amps to work in mono, stereo (two-channel mode) or bridge mode, which is always mono. A built-in CROSSOVER switch lets you put the amp into bi-amp mode, which sends low-frequency content (<100 Hz) to the CH2 Output and the high-frequency component to CH1 automatically, no external hardware required.

Behringer's EPX Series amps are built for the working musician. They are much lighter than conventional power amps, pack massive power, feature built-in crossover and limiter circuits, and can withstand the rigors of the road. Plus their light price tag will leave money in your pocket to buy more stuff to amplify!

Behringer EPX4000 4000W Lightweight Stereo Power Amp w/ATR
Behringer EPX4000 4000W Lightweight Stereo Power Amp w/ATR is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Subwoofer Amp ApplicationPurchased for use as amp for 2 15 inch subwoofers in HTR application. I was tempted to go with the INUKE 3000 w/DSP, but was afraid it didn't have enough power. Also was hoping this unit would not require separate level converter since it has RCA inputs.I had to turn the gain all the way up when using the RCA inputs directly from my HTR receiver. It worked, barely, but I went ahead and bought a level converter since it had no headroom. Now there is plenty of margin. The unit has plenty of power and a nice clean output. I wish it had the DSP, that would make it perfect. The fan noise needs to be addressed. I put the amp in a cabinet and now you can barely hear them when the room is quiet - and not at all when in use.

Rated 5 out of 5 by from Home Theater brute with LOUD fansWill produce very high SPL with my dual 15" Polk MM1540-DVC in a custom box wired for a 4 ohm bridged load. Very good transient response -very clean, dynamic sound. Power supply has HUGE reserve. My receiver will not drive this amplifier into steady clipping even with bass music (Bass305,DJ Magic Mike,etc), which is just fine because it outruns my receiver in a big way.The down side is the fan noise, the cheesy appearance, and the exaggerated power claims. my answer was to hide it behind the tv face up and come to grips with the fact that it does about 2400 watts clean into 4 ohms bridged..... This is a really good performer that is built like a brick. Definitely the biggest bang for the buck I've comeacross.

Behringer EPX4000 4000W Lightweight Stereo Power Amp w/ATR

I am looking to use this amp for HT. Is the fan noise low enough not to be annoying at low volumes (it won't be hidden)? If not, what do you recommend? Would the LFE out with XLR from an Emotiva pre/pro work?

Asked by: Bass addict
The behringer EPX4000 uses two cooling fans and will generate some noise. Yes, you can use with an LFE input to one channel.

For HT application - I am looking to drive 2 x Dayton UM15 (run in series parallel at 2 ohm) with one channel and 1 x Dayton UM15 (run in series at 4 ohm) with the other channel. Please confirm if this amp can drive different ohm with each channel.

Asked by: Bass addict
Yes, You can use each channel separately in stereo mode only at different impedance loads.

Hello, I am interested in using this to power a pair of stereo subs. Signal will be from a typical hifi preamp, not pro audio equipment. I am not familiar with the Dbu input sensitivity rating of pro equipment. Is a typical hifi pre output sufficient? Thx
