One final thought because this has been brought up before and will probably be brought up again. BTW, I am not saying this to pick a fight or to call anyone out. It is just something amusing that always comes to mind. Whenever someone says the amp can't do what it does because the Laws of Physics state XXXX. I am always reminded of the old Bumble Bee adage. Don't the laws of physics state there is no way a Bumble Bee can fly? Yet it does, and why you might ask? Because it wants too. ;D

I knew it was out there, it just took me some time to dig through and find it. According to the DIN 45000 specification for testing amplifiers "Continous" power output is defined as... "Power measurement of an amp requires that the amp is properly terminated by Ohmic resistances of nominal value both at input and output. The continous power is measured when the amp is supplied by its normal power supply. It must then be able to deliver the rated power at 1 kHz for at least 10 minutes while the maximum THD does not exceed 1 %." All of our amplifiers will easily exceed this specification adn in fact our own internal testing is far more rigorous. I knew the spec was out there, but I didn't want to say anthing until I found it so I could quote it correctly. In short, all of our amps meet the "Continous" spec. Just thought everyone would like to know. But we knew that before even Jesus was born! ;D * Bumble Bee? ...These are my friends, and I fly with them occasionally.

Sounds to me like you got a BS in Philosophy! ;D ;D ;D That's right, a Baccalaureate in Sciences (BS). ...And a BP too. - Erwin, Money ain't dimensional, it's an illusion. Teacher said: time is the fourth dimension. And we all know time = money, Hence, money is the fourth dimension. ;D

Hold on for a second! DIN stands for "Deutsches Institut für Normung e. V." as we all know. Question is: do we really trust the Germans? For all we know, it could very well be an attempt to subject the world to their devices... Think about it!

Although the spec you are asking for is not directly shown, it is easy to derive. On page 6 of the AP report you will see that there is less than .08% deviation across the band. This spec does not change at any power level so when you look at page 3 which shows power output of all channels driven, it will have the same power band response even at that level. Hope this helps. Yes it does, and your reply is much appreciated! ;D

Don't be, your amps still work as advertised!

what we should be asking is what the rating is before failure happens, not the advertised spec we see in product specs.. as we all know the emo amps only have a reserve power rating..
it would nice if some co's would actually release the full power spec of what amp is capable instead of a bs theory of a reserve limit that may be published..
from an avr standpoint for amp power i usually allow a 15-25% less per rated watt..

What we should be asking is why people don't buy an amp ,with a warranty, decide if it's enough power and move on.We should be asking why people don't trust their ears? instead they need confirmation from numbers or other people, very odd, only my opinion though.

You have a point there. Makes you wonder why we scrutinize every detail of a Specs while we just LISTEN with our eyes and ears with regards to wires and interconnects. But if we just move on aren't we just perpetuating the status quo?

What we should be asking is what the power rating is when it is up-side-down inside of a paper bag falling out of the 3rd story window in the rain while being hit with a baseball bat..... p.s. I agree with moe, sorry for the sarcastic comments but its how I fell about this thread

Why did only ONE person I saw (I could have missed it,) mention that continuous was defined by the FTC as being 5 minutes? That's my understanding of the 1970s version of the FTC rule. I did not see a follow up on this simple post.
Rather than arguing about what is continuous, why not just ask. So I am asking? What does the FTC currently define as continuous?
Has this 5 min rule changed? Was the post claiming the test is for 5 mins based on incorrect info? Can the Emotiva amps deliver rated power for time period the current FTC rule calls for?
Just curious?
