Hi Darryl and PPPPenguin,

I've started to build the hard part.

I meet some problem concerning the signal coming out from the NEXYX2.

All the signals driving low frequencies are OK but the output signals of high frequencies are not square but triangular.

For example, the sampling clock signal at 6 MHz for the TDA8708 and the clock signal for the TDA8702 are not visible at all.

Is-there some trick for driving hight frequencie signal?

Thank you very much.

Frédéric.
