Micromega Tempo 2 problems

Hi,
I have impossible problems to solve on this amp.
This is a 15 kHz sine wave at 500 mW. Other frequencies look the same. Offset at 200 mV… with zero offset, the signal looks totally distorted.
The second picture shows the same input at 1 W
The third photo shows the same input on the other channel.

Any thoughts?
