Product Details

Behringer EPQ900 900W Lightweight Stereo Power Amplifier

The EPQ Series power amplifiers pack the power of Accelerated Transient Response (ATR) technology into an exceptionally lightweight package. Ample power and high-tech efficiency combine to give you a feather-light supercharged workhorse that will keep your rig kicking for years to come.

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

Instead of operating relatively continuously like most power amps, the EPQ power amps 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 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.

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.

The back panel of the EPQ900 accepts balanced XLR. The EPQ900 has MONO On/Off and BRIDGE On/Off switches.


Behringer's new EPQ power amps are built for the working musician. They are exceptionally light, they pack massive power and they are built to last through all the rigors of the road. Plus its light price tag will leave you with enough cash left over to acquire more stuff to amplify! Check out the EPQ series and find out why Behringer power amps are among the most popular on Earth.

Is this the right adapter (part # 248-9886) to run the amp in stereo mode from my smartphone?

Asked by: efrantz
Yes that cable will work fine for that application.

How would I run this amp in stereo mode with just a smartphone plugged into it? What adapters would I need? This amp should power 8 aura speakers with a set of 4 in series/parallel per channel, right? If so, would they run at 68 watts rms @4ohms each?

Asked by: efrantz
Yes this amplifier will power 8 of those wired in series parallel with 4 on each channel. The adapter cable you would need would be in the link below, be sure to check volume levels before anything is played through this, the volumes need to be on minimum before a signal is applied.

Hi, does this amp have fans, and if so would the fan sound level be considered to noisy for studio applications?  Thanks!

Asked by: Nyah
Yes this amp does have fans in it. They will probably be audible but I cannot say if they will be too loud for a given application. You may contact Behringer to see if they have an average decibel level at a given distance.
