My understanding is that with movies (Cinema preset), Meridian boosts LFE by 10dB, but reports it as 0dB (which is the correct thing to do), because, to allow an extra 10dB of volume, the LFE movie channel is recorded at -10dB vs. the other channels. With music (Discrete preset), that boost is not applied as it is assumed that the LFE channel in the recording is at the correct level with respect to the other channels.
I will make some measurements this week-end to see if the Cinema preset is doing a +10db boost or not.
