Right. But the MADI-to-AES alone (the ADI-6432) costs about 2800€. Far beyond 1) and 2). > What are those AES ports needed for anyway? I mean, this are 16 channels > in and 48 channels out.

Yes AES makes it all over complex but it is a requirement not a decision.

Will try that with a couple of hammerfall 9632 we have in the lab before buying the (two) AES-32. Any recommended documentation or advice?
