New Behringer Amplifiers - Oh Oh.....

On another thought here, maybe this discussion will help other DJ's that have 2 subs and 2 mains on poles above the subs streamline their setup :)
 
coupling is good, yet another different representation.

comparing apples to apples, their diagram is correct from what I can tell.
 
a couple more points

One other thought... suppose the tops were bi-amped?

It makes no sense to buy a significantly larger amp than is necessary. Setting up a system with one chassis supplying the highs (lower wattage) and another supplying the lows (higher wattage) would be most cost effective.

Unless Clark has a better suggestion, I assume the easiest way to handle the transition is an adapter cable going to Speakon #1 on both amps. This would allow a four conductor to each speaker cabinet.

One other point about the built-in amplifier filters, if you are driving a ported sub, ideally (in a perfect world) you'd want a band-bass filter rather than a low pass shelving filter. In other words you want to sharply cut off 24db/octave below the resonant frequency of the sub.
 
I'll stick to my QSC'S.

I don't give a damn how cheap the b-ringers are. I don't buy Mike shoes, I buy
NIKE. A knock off is a knock off no matter how you look at it.

It is cheaper for a reason....I don't really want to find out why it's cheaper at my show.

I buy my amps to last for years.

In this particular instance, the built in crossover is 100Hz, so you won't be bi-amping just the tops with it, it's designed for subs and tops with passive crossovers in them.

On the other hand, there is a good reason to have plenty of power going to the highs, no chance of clipping the amp and causing diaphragm failure. You can clip the amp on a sub for a long time before there is an issue, but do it to a horn driver and it'll be gone pretty quick. Just because you have 1000 watts available doesn't mean you have to use it, it's just lots of headroom.

As for hooking it up to separate amps, I use a patch panel with the speakon connectors on it, and the wires from the back of the panel going to the respective amps. For those who tri-amp or quad-amp, there are NL8 connectors and cable available also.

Here's a couple more good reasons to use a patch panel:
- easy to get to. Don't have to reach inside the rack and find the socket on the amp, it's right there at the back on top (or wherever you put it) and hopefully labeled clearly.

- if and when the socket wears out and gets loose or breaks, you can replace the socket on the panel much easier than you can replace the socket in the amp.
 
This weekend at my prom, My 4th PLX3602 to blow in 3 years went.

Every one of them has been in the shop at least once for one of the following..

QSC's manufacturing defect in not securing the main Capacitors on the board so that they can't jiggle in transit and break the legs..

QSC's failure to support the monster choke they hung off the board with 1 1/2 inch legs which also broke

QSC's accidentally shipping them with the wrong size fuses in them, so they all blew the first time I used them...


I own 6 3602's, they're great amps, but my 6 Behringer ep-2500's have always been there to pick up the slack when the QSC's took a ****.

Not one of the Behringers has has a single problem...

And you call them a knockoff....

Isn't the KV2, and the QSC, and the JBL, and the Dynacord a Mackie Knockoff? I mean they were the first mainstream self powered speaker...

And aren't the Weidamarks, American DJ's, Chauvets, Irradiants, and every other LED a Color Kinetics knock off? They do of course hold the patent on RGB color mixing... Why would you buy that cheap off brand crap? Only the $2000 color kinetics fixtures are quality!

And how about Global truss, aren't they a Trilight knockoff?

Ford Manufactured the first consumer car... is your chevy a knock off?

Edison invented gramophone technology... Is your technics 1200 a knockoff?

The benefit to many of the so called Knock off products is that they've had the benefit of learning from the mistakes made by the originator of the particular idea...

Behringer makes a mean amp! They've held up better than my RMX series amps which have all also had problems..

My Amps get 6 and 7 day a week use, they're not sitting in my garage 24 days a month and getting armoralled in between. My real world experience has shown that my behringer and crowns have been bulletproof. I'm not a big crown fan, but I've got a few.

Also, open up an RMX and an EP amp... they even use the same components...

lastly, Behringer is German engineered... everything else German engineered is considered superior... why not Behringer?

Both QSC and Behringer are manufactured in China, so where's the massive quality difference?

Behringer's mixers have lexicon on board effects, and have lower noise floors than the Mackie CFX and DFX lines.. Yet they're half the price...

Someone finds a better way to manufacture, and a cheaper means of distribution, and everyone instantly craps on them...

Find me another company that has a 1 year direct replacement policy! If your behringer product dies, or malfunctions, bring it to the store you bought it from, and they'll hand you a new one..

That's pretty cool in my book...

I definitely am a top of the line gear guy, and I don't think for a minute that My $3000 Allen & Heath Mixer is on the same level as a Numark, gemini, or Denon Mixer... It's not, it's superior! However, a Behringer, and a Denon 900? There's not much difference... they're both low end DJ Mixers...

However, Behringer's new Digital Midi DJ Mixer is taking the PRO world by storm... it's a stellar piece of gear!
 
Its funny how I posted side by side pics of the EP2500 and the QSC RMX and many said " Looks the same, but the Behringer is DEFINITELY using inferior components, how else can you account for the lower price?"

Then DR Zinc posts about the affordable GTD amp and shows naked pics and everyone says " Oooh it looks beefy, looks like a quality amp" . This inspite of no one having any experience with it.

Its funny how no one is questoining how QSC was able to come up with a $299 GX3. Does QSC's $299 buy more quality components than Behringers $299? Behringer does volume. Thats how they keep prices low. In Asia, it is a big brand. Sure QSC is still the brand to lust over but in a Third World country, they do not have the cash we have here in the US of A to drop on a QSC. They are working moblie djs just like us. They need to turn a profit and they cant do that if they buy QSC.

Back in 1968, GM laughed at a small knock off car company that was trying to sell a micro car of sorts, the Toyopet.It was small, cheap, had a miserly 4 cylinder and not a brash V8. That Company today is Toyota. GM is about to go BK and is in the toilet. Yup sound thinking.
 
Umm, I Would Not Run A Behringer Amp @ 2 ohms...

>>> A knock off is a knock off no matter how you look at it.<<<

So True !

I borrowed a behringer EP2500 a while back when one of my other amps was dead. I ran it hard, bridged at 4ohms, and it handled it just fine.

Bridged at 4ohms is exactly the same load to the amp as stereo in 2 ohms.

Wow, This Turned In To A RANT...

First Off, Never Had A Bit Of Trouble Out Of Any QSC Stuff.
I Have 3 Behringer Piece Of Crap Mixers (VMX1000 7-Channel DJ Mixer).
Ok I Know They Are only $200 Bucks, But So were my Numarks...

I Ran The Newmark Mixers For About 6 Years.
The Behringer Mixers Have Been In Play For 2 Years.
( I Plan To pull Them As Soon As Proms Are Done ).
All 3 Have Some Kind Of Issue,3 Different Issues.
They Have Been Mounted In The Same Racks As The Numarks.
They Have Been Worked As Hard As The Numarks, And Now They Need To Be Replaced.

I Had Some Behringer B212A Powered Speaker (400 Watts, 1x12 in.)
Used Them As Back Up Gear & As House Gear For A Regular Gig On A River Boat.
The Speakers Stayed At The Venue & Were Only Used On The Weekends At LOW VOLUME...
I Also Used Them For 3 Off Site Gigs As Zone Speakers ( Voice Annc. Only In The Zones).
Yes They Were Only $200 or $300 Hundred Bucks, But They Only Lasted 1 Season...
The Tops Gave Out In 3 Of The 4 Speakers...
( Umm How Did that Happen To A Self Powered Speaker?).

So What I Am Sayin Is, Based On Me Owning Some Of This Stuff I Don't Trust It For My Gigs...

All I Am Sayin Is I Ain't Buyin Anymore Of The Stuff...

Ok, Done With My Rant...

About The Toyota Vs Chevy Stuff.

Toyo Was Not Makin Knock Offs They Were Makin A
Small Car To Sale In A Market That Was Full Of BIG Cars.
They Gave The Buyer A Choice, & They Made A Good Car.

Behringer Is Making Sorda Kinda Look A Like Stuff & They Sale It At A LOW Price.
( I Call That A Knock Off ).

My 2 Cents
 
I have also seen Mercedes on the side of the Highway with smoke coming out from under the hood!
