Presonus Adat outputs

dnz's icon

Hi there

I'm working on an installation that required 24 channels of audio. I've got a presonus firestudio 2626 and 2 behringer ada8000 convertors. Using 2 Adat ports on the Firestudio wsould give me 16 channels of audio. But I'm not successfully getting adat channels 9 - 16 as outputs to my amplifiers.
I've hook adat channel 1-8 and 9-16 to each of the IN on the Behringer. Sync is set to the Firestudio as Master. I'm using dac 1 2 3 ... to 24 as my outputs. I'm only getting sounds of our channels 1 thru 8 and 9 and 10 ?? and channels 17 thru 24. Does anyone have any experiences with these pieces of equipment? any advice why this is so?

best
