I would say 600w is a closer estimate.....reference design is for a single pair of devices.
6kw seems beyond specs...

I do not know, a class-D amp with 90% efficiency and voltage 85v +85 v only with 600W of power ... Hmmm, I think it gives a little more than that!
Let's do simple math,
1 x 4227 = 500w
From the schematic , it uses 6
6 x 500w = 3000w
Bridge 2 x 2092
2 x 3000w = 6000w
...... come back to reality .....😀
before even going to the reality can those bjt really drive the gate of those 4227 safely at full power? and what is the switching frequency?
i have the pdf version of the schema . but can those bjt's drive the output fets safely at full power?
hey guys i've found it's posible to drive output power fets with bjt it is called tontem pole. thanks to ir company ir amp9 is similar to what this thread is all about
but produces 1.7kwt instead of the 6kwt as in this thread

I have found one pair of 4227 will give 500watts and two pairs 1000watts.
So their 3 pairs at 1kw7 sounds right.
