For those contemplating stepping into ATMOS once the boards become available, one question that needs to be addressed is whether or not Emotiva will also be providing the proper mic calibration file for the height channels in addition to an updated version of DIRAC that allows for these added channels? While the 90 deg. off axis cal file is correct for the 7 bed channels, the height channels would require a 0 degree cal file as the microphone is pointing parallel to these speakers (pretty much). In talking with the tech department, they did not have too much info at this time, other than it would be their intention to integrate this into their setup but no time frame could be given. Seeing as how DIRAC and PEQ cannot run simultaneously, it would seem that the software and cal. file update would have to occur at the time of the hardware release. Hopefully someone higher up can shed more light on this topic.

Thanks for the info. Currently the only way we are able to calibrate for height channels and any calibration software is to use dual miniDSPs with DIRAC and run 2 different mic calibration files with the results loaded into individual memory slots of the miniDSP units synched together. It works very well, but is time consuming as it takes three separate calibrations with the third to gain match the height channels to the main bed channels. Once complete we then have to run Audyssey to time align the two miniDSP units and readjust level trims. The point is that we are using two different pieces of hardware working independently. The pre/pro is a single unit and the software is setup to work with only a single calibration file.
I don't know when the info you quoted was posted, but given how involved the process would be to make the software do what is outlined above (if possible), I would be surprised if the revamp of DIRAC coincides with the XMC-1 upgrade.

The Dirac software doesn't need to do what you outlined. It simply needs to use one cal table for the heights and a different cal table for the rest of the channels. Once the filters are calculated by the updated software, the XMC-1 portion is pretty much the same (same processing, but more channels).
I wouldn't be surprised if the updated XMC-1 ignores this issue and still has one cal. Let's hope not that's not the case, but it probably wouldn't be the end of the world. As it is, the mics are batch calibrated and 0 vs 90 on my mic don't really drift apart until 4KHz.
