Hi,

just wanted to aks if there are any possibilities in SigmaStudio to generate a 24x24 Cross mixer in a ADAU1442 DSP.

The normal Cross Mixer is limited to the 8 Inputs. Is there any workaround to achieve such a big mixing matrix?

Tobias, I think the limit to 8 inputs was mainly done due to screen size. You can easily create multiple instances of the 8-input mixer and then just add the outputs. If you have 3 × 8-input mixers and sum them in a 3-input summer, you get one 24-input mixer. Then you can copy-paste that 23 times to get your full 24 × 24 mixer.

It would be nice to have a compact cross mixer cell with many inputs and outputs. I will put this on the feature request list for SigmaStudio.

Thanks for your solution Brett,

i think it would work in the way you described it above.

As you already posted it, i also think it would be nice to have such an expandable Cross Mixer up to 24x24 channels in one of the next versions of Sigma Studio.

Best Regards

Tobi
