Everyone that plays in a live band knows that you need a good mixer at the heart of your P.A. system. Many musicians who are building their first PA system spend a lot of time researching and choosing a mixer and completely forget that they will need a good power amplifier to power that mixer. Today I’m going to talk about an excellent, affordable power amplifier that will work with any mixer. I’d like to introduce you to the Behringer Europower EP4000 stereo power amplifier.
The Behringer EP4000 stereo amplifier delivers 2000 Watts per channel into a 2-Ohm load when used in stereo mode or 4000 Watts into a 4-ohm load when running in bridged-mono mode. You’ll want to note your speaker load when pairing your speakers with a power amplifier. Most speakers are rated at either a 4-ohm or 8-ohm nominal impedance. This is important because every time you double the ohm load on your speakers the power from your power amp drops. For instance, the Behringer EP4000 hooked up to a 4-ohm stereo load produces 1400 Watts per channel and when it’s hooked up to an 8-ohm load the power drops to 750 Watts per channel. That’s why it’s so important to match your amplifiers power output ratings with the nominal impedance of your speakers.
I use the Behringer EP4000 to amplify my Behringer Xenyx X2442USB mixer and my JBL JRX125 speakers and it’s an excellent combination. The JBL JRX125 speakers run at a 4-ohm nominal impedance and the 1400 Watts per channel from the Behringer Power Amplifier really crank out the volume. The Behringer EP4000 amplifier has both Speakon and Terminal output connections and connecting my JBL speakers is quick and easy with the Speakon cables. I connect my Behringer Xynyx x2442USB mixer to the EP4000 amplifier inputs with XLR cables. The EP4000 amplifier will also accept 1/4″ TRS balanced connectors or 1/4″ unbalanced connectors as well. The amp has every available connector type for hooking the amp up except for 1/4″ output jacks.
Another feature I really love about this amp are the mode switches on the back of the amplifier. These switches allow you to easily turn on or off some of the amplifiers features. You can turn on or off the clip limiter or the low cut filter as well as selecting your low cut filter to cutoff at either 50Hz or 30Hz. You can also use the switches to select either Stereo Mode or Bridge Mode.
The front panel of the amplifier is simple and clean looking. There’s a power switch, two gain knobs, clip LED, signal LED and a power LED. The amplifier also features fan forced air cooling with a variable speed fan that changes speeds with the amplifiers cooling requirements. The EP4000 weighs in at 37 pounds so it’s not a lightweight amplifier but it’s not outrageously heavy either.
The Behringer Europower EP4000 Stereo Power Amplifier is a very good amplifier and worth more than you’ll pay for it. I am always cautious when recommending Behringer equipment because of their notorious build quality. I have spoken to several people who own this amplifier and have not heard of any reliability issues which is rare for a Behringer product. These amplifiers seem to be extremely reliable and I haven’t had any trouble with mine.
As for sound quality, I think the amplifier sounds excellent and I’ve been very happy with how it sounds pushing my JBL JRX125 speakers. I really don’t think you can go wrong using the Behringer Europower EP4000 to power your P.A. system. If you have any more questions about this amplifer, here’s a link to download the user manual:

Musician’s Friend also has an excellent speaker and amplifier package that combines the EP4000 amplifier with a pair of Behringer B1220 speakers. See the links below to purchase these items.
