Curious as to how people are solving the following. My mix room is setup for 85db all round as per Atmos specs. When creating a down mix from the atmos master, be it 7.1 or 5.1, for playback in cinemas that have their surrounds calibrated at 82dB does the renderer allow for the 3dB drop in the surrounds. If not then surely I have to raise the surround channel levels within the 7.1/5.1 file by 3dB?

The RMU compensates the 3dB for the 7.1 and 5.1 re-renders for you.

Thanks Frank. That's the RMU. Do you know if the DAR software does the same when creating re-renders?

The DAR/HE-RMU does not compensate the surround levels for the 7.1 and 5.1 re-renders. You will have to raise the level of the surrounds channels manually for it to be correct for cinema playback.

Thank you espron. I was afraid of that.
