Ice1000 ASP technical question


In the PDF with tech specs here

http://www.icepower.bang-olufsen.com/files/solutions/icepower1000aspdata.pdf

it says on page 10

"Damping Factor
...The three curves relate to the different curves of the output impedance."

That last sentence makes no sense to me, and there are three vastly different curves under the sentence. The three colors are used nearby to indicate different Ohm levels, but this is a 4 ohm chart. The values are very very different! (for the three curves I mean)

Does anyone know what the three curves are? I need to know the damping factor, and can't figure it out from this - at 4 ohms.

They try to show effect of 2x and 4x lower speaker impedance - so for 4 ohm speaker two other traces are 2ohm and 1ohm. Not only that 1000ASP is not rated for 1ohm but traces should not meet at 1kHz since it is always ratio of speaker impedance to output impedance. IMHO they screwed it up. It is done properly on 200ASC datasheet page 14

I would just ignore two other curves and use uppermost one (red) on 4 ohm chart.
