I don't need a graph of my one, it is already in the datasheet:
At the marked part you can seen the protection kicking in. Completely inline with Amir's measurements.
You can't either, you can clearly see the current limiter kicking in at the 2 ohm and 4 ohm BTL graphs in the Hypex datasheet.
If you want real continues power at 2 ohm, buy something like this:

Owned a pair of these...
Ok, Hypex states 180 W at 2 ohm at 1 kHz and tell that is current limited. They even provide a measurement at 3 different frequencies where you can see very clear to show this. Problem is that many people can't read graphs....
Maybe reading the Hypex specsheet will help for some people. They state 180 W at 2 ohms at 1 kHz and say it is current limited.
The graphs are very clear at this:
You can see this also in the BTL setup at 4 ohm:
There are 2 protection systems, one over current in the amp stage and also...
Don't try to do distortion measurements with those cheap 6mm capsules:

Even a cheap dynamic mic is better!
I bought a very expensive NTI M2215 ( same class as B&K and Grass)...
The secundaire powerrails voltages in an amp are not a problem because you can step up in voltage from the mains, transformer or smps. Main problem is the current in the primary side with high power amps. Large Touring companies like Claire Brothers in America ( Bruce Springsteen, M Jackson) use...
It's not blatently obvious. Hypex sell kits with 2 Nilay's with one smps500. Purify uses 2 modules with one smps1200. And these type of configurations are no problem because all Hypex smps have current protection build in. What is bloody obvious is that this smps was faulty from the start.
