Bullshit Alarm

Its impressive Behringer how much Power you get out of 620W Mains. Perhaps its because of the 10 Cylinder V-Motor

Well duh, it's a POWER amplifier! You put 600W in and can get 6000W out! Can't you read? 

[The Soulman]

Well output power is correct but they should state it as WLS.



WLS stands for: When  Lightning Strikes

Even when its a Typo mismatch, the IEC-Plug and the Speacons dont support 30A

From the wiki:
"PMPO[edit]
PMPO, which stands for Peak Music Power Output[22][23] or Peak momentary performance output,[24] is a much more dubious figure of merit, of interest more to advertising copy-writers than to consumers.[25] The term PMPO has never been defined in any standard,[26] but it is often taken to be the sum of some sort of peak power for each amplifier in a system. Different manufacturers use different definitions, so that the ratio of PMPO to continuous power output varies widely; it is not possible to convert from one to the other. Most amplifiers can sustain their PMPO for only a very short time, if at all; loudspeakers are not designed to withstand their stated PMPO for anything but a momentary peak without serious damage."

6000W PMPO x Bullshitfaktor = 120000W BullPO

Thei call it "professional" and engineered in Germany

Yes PMPO can actually be easily calculated from the WLS rating: PMPO=WLS/4
So 6000 Watt WLS /4 = 1500 Watt PMPO/10 = 150 Watt RMS

Also the Italians can play this game.

4800 watt output power bridged at 4 Ohms, (only one iec power input connection.)
102A peak output current (thru a single 6A rated phoenix style output connector, never did see one fail  )

This is how we (used to) do it:

Being a marketing arsehole is irrelevant of race, creed, gender or religion.

With that much BS on the output rating, you can guess that even the power input is exaggerated.

The line input power rating is something that safety organizations enforce, but only as an upper limit.  They can state '620W' even if this amplifier never draws more than a few watts.  As a guess, they picked the largest number that still allowed them to ship the cheapest power cord.

Internally this probably uses a TDAxxxx run at the upper voltage limit.  No matter how generously you define "peak" and "instantaneous", the output power will be limited by the resistance of the inductors and ESR of the capacitors to a trivial fraction of the claimed 3100W.

My mom wasted a lot of money on a QFX branded boombox that was rated "3000Watts." I told her no way in hell is it 3000W, probably uses some chipamp inside.

She didn't listen, bought it for $300. After a year, the 3.5mm jack broke and got stuck inside, so I had to open the thing and desolder the 3.5mm jack and replace it. Guess what I found inside the boombox? A TDA7294 chipamp on a really thin heatsink. Next to it, the power supply board: a SMPS in push-pull configuration with a SG3525 controller, and 2 TO-220 mosfets to drive it.

I thought Behringer were a reputable company?

They're probably breaking some EU regulation. If it gets to you that much, contact the authorities.

[mc172]

I thought Behringer were a reputable company?

Their amplifiers at least are reputable because they copy QSC.

I think the issue here is flouting tests. It happens all the time. The power consumption figure is probably at a given output power, or at maximum effieciency and the max. output power figure is probably at 50% THD - neither of which are realistic or sensible.

Maybe somebody accidentally took the leash off of the marketing team...

I love my DEQ2496, sad to see them stoop to this level.

[brainwash]

Behringer was always a cheap brand, can't remember one time it was associated with quality. It is however affordable studio equipment.

I have friends who use their equipment in a semi-professional setup (studio or PA) and they've learned to always have a spare. Or learn to solder, which most of them did.

I had a Peavey Auto-EQ until a few years ago, but it did not look as snazzy as that Behringer DEQ2496. It only had a monochrome screen...
Not trying to trash the brand, but it's just 'home gamer' stuff which gets you a lot of bang for the buck. But cheap sliders, cheap switches, noisy power supplies, cheap caps and cheap connectors do not mix with reliability or earning a living out of them.

[Red Squirrel]

There seems to be lot of BS like that in even the pro audio industry.   Was sourcing out equipment for my church and saw a lot of amps that had a rating higher than 1800w, which makes no sense as that would max out a 15 amp outlet, which this stuff is typically designed to plug into.

Suppose there is probably some "truth" their their statements, they probably mean that the amps could in theory handle that without blowing.  But it's still very misleading to the average consumer.

To anyone that wants to show me a new 300-1000W amplifier from Amazon - I just make them listen to my matchbox LePai amplifier, also known as el-cheapo TriPath. It runs on 12V@2A and was about 15 EUR, delivered, including power supply. Not actually matchbox-sized, more like cigar-box.
One of them drives a pair of 160W Magnet speakers and fills a bedroom at quarter volume.
The other one drives the subwoofer after a "1000W" Sony amp.
You get a new appreciation for speaker power after listening to one of those small things.

It might well be 3000W peak output.

The 'peak' is just whatever the capacitors can shove down a wire for an instant.

Class D can be very efficient, yes.

That means you can pack them into small spaces, unlike those Class-A monstrosities from the 1980s which were 90% heatsink.

(The audiophiles still want the class-As, naturally...)

Yes, but the output voltage needs to be high enough to deliver the power into the speaker. V = (R*P)^0.5 so it will have to output 111.4V for 3k1W peak into a 4 Ohm load. Unless it has a class D output stage, the efficiency will be miserable at lower power levels.

Peak output can easily exceed peak input.  This is why filter capacitors are used.
