Hi Blossom,
Many thanks for your interesting answer.
Of course,I carefully red the pdf file: http://www.ti.com/lit/ds/symlink/tpa3116d2.pdf
There are 2 occurences for word BTL.
I only found this words:
The TPA31xxD2 family can be connected in MONO mode enabling up to 100W output power.
As I am not an ingeneer, this is why I kindly ask for a feed back:
as the gain is fixed, let say to 36, what bring more output power?
Maybe a short answer in this way can help me a lot to understand.
Regards,
Christian.

I asked the question re power from PBTL mode on the main 3116 thread. The answer I got was:
"PBTL power is 1 to 1.5 watts above BTL, you could say they are equal."
PBTL gives you the ability to drive a 2ohm load to 100 watts but no great gain in watts for 4 or 8 ohm.
Well, they are here.
I found that I made a little error on some of them.
The exposed ground plane did not get copied on some of them.
The area along the edge at the input side, the area under the IC (only required for TPA3118), the area at the outputs for larger bootstrap capacitors and the area under the output filtering is not exposed.
I have offered some people a slight price reduction and am waiting for three more replies to see if I need to order an additional batch to cover all orders.
The KIT price has been placed in the first post.
My apologies for the error.
