Using a CP950 to send a multicast flow to a Dante Chip via AES67.
Hi all,
We are trying to set up the CP950 to send 5.1 output via AES67 into an Allen & Health SQ Dante 64x64 chip mounted in the back of an Allen & Heath AHM-32 Matrix processor.

Then the goal is to have the analog outs of the AHM-32 distribute to auditorium speakers.

We have everything connected and the CP950 is taking in audio and appears to be sending a lot multicast packets.
However the step that we are stuck on is being able to see the AES67 output of the CP950 within Dante Controller - it simply won't show up.
As advertised, we should be seeing an AES67 flow from the Dolby like so:

Please let us know if anyone has ideas!

    I have this same problem. I would need to get CP950 outputting AES67 feeds to Yamaha MRX7-D DSP. I have created SAP annoucements with RAV2SAP, but no audio.

    Any ideas how get AES67 feeds to 3rd party AES67 receivers.
    I tested also with Audinate AVIO output interfaces and Q-SYS Core but no luck...

    Please give some help with this.

    Apologies for the late response and thank you for your patience. We've followed up with support engineers and they've responded with the following:

    The CP950 and CP950A are not Dante devices and the AES67 implementation, Dolby Atmos Connect, was originally designed for use with other Dolby products. That said, there are some AES67 devices that have specific implementations to support for CP950 and CP950A and some AES67 devices that can be configured to work. Please contact Dolby Cinema Solutions and Support using email at
    cinemasupport@dolby.com for further information.
    • I was able to bypass this issue when trying to connect to our Qsys Core. I used a BLU-DAN to convert from BLU-link to AES67 and the flows show up in Dante as expected.
