Behringer EP4000

[Mika75]

So what is the difference between the 2500 and the 4000?

The graphic on the faceplate is much nicer I guess... Ohh, and if ur out there listening Uli - Use a silent variable speed fan on the EP series !!

I've Just bought an EP1500... It's very noisy, too much! The problem is that new models should already have the variable speed fan.

Now I need another to drive a special subwoofer(very special subwoofer, powerful than a DD18 and Its components coast only 700€), I was looking for the 2500...
So, I understand that the EP4000 can seems the same, but I really can't understand why Behringer shuold sell the same amp with two different names
Maybe there is one little difference (for example a less noisy fan)...I DON'T KNOW

Replacing the fan is very easy to do. And I believe has been linked in this post already.

It takes a screw driver and a new fan. It's not hard. This amp was made for concerts not driving home speakers. We can mod it with a quiet fan for home use. At the price you can't beat it.

Yes I know....but I've lots of reasons to don't do it... A part that I'm in Italy and I don't know where to find the components, second the noise decrease, that if I remember well in the thread was 3dB... you know... 3dB is not an impressive result and there is the risk to invaid the guarantee opening the case and to damage the amp cause sometimes I listen to very very hight volumes
What do you think about the QSC RMX2450, i heard is the same amp with better components. It costs perhaps 200€ more, is it a good choice?

it's not 3db

and i'm from the Philippines

 

[ParadigmDawg]

I would guess mine went down by 15db. It was very loud and now I can't hear it at all.

The QSC RMX is what Behringer knocked off to build the EP series. The fan isn't quiet though. Look at Crest Audio. My CC series amps are silent. They build fantastic amplifiers too. QSC makes a great amp too, but the RMX isn't really quiet if that is an issue.

8dB I'm sorry, much better!

One more question...I read somewhere that the 2500 has some problem to drive 4Ohm load bridged (that is like 2Ohm per channel I think), is it true? cause i need one for a 1500w @4Ohm subwoofer

Nah, it'll be fine.

 

[Mika75]

2 x 1,200 Watts into 2 Ohms or 2,400 Watts into 4 Ohms bridged mono operation.

I assume/believe he read that, he was probably reading that a lot of professional users of them have had problems running 4-ohm and 2-ohm bridged loads because the EPs overheat. But for a home subwoofer it should be fine.

What are you driving that needs 1500w? Sealed JL Audio

A Behringer can pull 20amps. Which is the limit of most home power outlets in the US.

It will do perfectly find in a nice cool home listening at normal volumes. This product is a cheap concert amp, so unless you plan on having large rock concerts at your house. You should have no issues driving you sub.

precisely there is who said that even if Behringher affirms there are no problems, the've got bad results with 2Ohm per channel speakers, so I thought it should have the same problems with 4Ohm bridged.

You know 2Ohm is very difficult even for expensive amps.

I haven't bought the subwoofer yet, I'm going to build it. This is the project.
This speaker is the best, used even in some hi-end HT

With different projects you should have 100db @20Hz 106 @30 120+ after 50Hz (closed box single woofer!) this results are considerable!

I would personally blame the operators on this overheating in the pro scene. The popular way to run a bass cabinet (standard 2x18" in this country) is to use one amp to power one cabinet. The EP2500 will output 2000w before exhibiting heat issues.

That's 1000w to each driver. To my knowledge, there is no single 18" that I know of that will use 1000w. I say use, rather than take. I've used a TON of 18's. Beyma, RCF, B&C, Eminence, PD, P.Audio, Selenium, etc.. The driver will most likely go into power compression far before 1000w. There's no reason to use more power than what's actually being used by the driver. You want it to get louder, get more cabinets.

Don't clip them and they will serve you well. That should be obvious with any power amp.

They're better than crown k2's. That should be enough.

It isn't the same amp, It looks similar but has different power ratings and options.

Well, amps usually have heat problems when being run too hard / having the limiter threshold set to soft. Some do a better job than others of saving themselves, but, its not fair to compare amplifiers that costs twice as much or more to a budget amplifier. Crown XTi's and Macrotechs have good thermal protection, the QSCs and Crests are excellent at that. These also do a better job of saving the speaker (rapid/ramping gain protection, etc.) But they also cost more, so, *shrug*

As far as no bass cabs needing more than 1000-watts, both places I play every week require more than 1000-watt amplfiers for the bass section. The Meyers do, the Bag Ends do. Like you said though, that's spread over multiple (2 or 4) drivers.

Some of the new d'n'b and dubstep soundsystems are using drivers with high power handling the the ported low end units before crossing over to horns for the +40Hz bass. But, I digress.

 

[tcarcio]

I did more asking around and I have to correct myself. In real wattage it is the same as the 2500. So I stand corrected.

 

[Mike82]

So the EP2500 puts out 650watts per channel in 4 Ohm when both channels are driven. The EP4000 puts out 950watts per channel in 4Ohm when both channels are driven. This info was pulled off Behringers homepage, is this accurate. I understand that the 4000watt bridge mono is not accurate but is the single channel stuff accurate. I am in need of a new subwoofer amp and the ep4000 looks better on paper than the ep2500. But if they are the exact same I will get the EP2500 and save a 100 dollars.

 

[Wafflesomd]

The EP2500 is the same amp as the EP4000.
