With Dirac mode set, my system stops getting louder when I hit 0dB. +1 through +10 volume levels appear to be the same as 0. This is not the case for the regular speaker presets.
When changing volume, I notice some soft clicking/distortion. Again, not present with the regular speaker presets.
Anybody else run into these issues?

I listen at or near reference for movies in my theater room. Every once in a while I go louder with music, but, yeah, it's near dance-club loud.

I just checked and the volume in my room stops increasing at 0 dB. No further volume increase all the way to +11, which is where my max gain is set in the XMC-1 setup. What's up with that?  I can't get the near field volume of my main speakers up past a mere 112 dB, as measured with my SPL meter.  Edit: At least I have no clicking/distortion. T- |

Any chance the max volume in setup > preferences is set to 0 ?

Try rebooting the xmc. I get clicks and pops every now and then when changing the volume and a reboot of the xmc always fixes it. I have my max volume set as 0 so can't speak to your other issue.

Sounds to me (no pun intended) that you need to pony up for more amplification and turn your volume back down to 0.  |

I think 800 wpc from a Crown K2 amp is more than adequate for speakers that are 92 dB at 1 W, 1 meter. That amp's input sensitivity is 1.4V, so that shouldn't be a factor either. T- |

I get the clicks or pops at all volume levels, when it occurs.
Does this happen all the time for you or is it a intermittent problem?

More amplification doesn't really help. I already have five QSC PLX2 amps for the theater. More importantly, I'm calibrating for reference level so 0db is always going to be the same regardless of amplification power, speaker sensitivity, etc. I'll doublecheck the max vol setting, but I'm pretty sure it was left at default. I can set volumes greater than 0, I just get no corresponding change in volume.
I get the volume change noises at all levels. I don't think I've had it go away unless I change to a different speaker preset. I'll try a power cycle since I haven't done that in a while.

But if I do, the SPL does not increase. T- |

If I increase my XMC-1'S volume control from 0 dB to +5 or whatever, I think the volume should increase accordingly, don't you? This issue issue is specific to the Dirac speaker preset. For presets 1 and 2, the SPL does increase as expected when the volume control is cranked up beyond 0. T- |

I reset and my volume change noises are gone. Would prefer it didn't happen in the first place, but at least there is a work around.
I confirmed that my max volume is +10 so it is not that. Only the Dirac mode does not function as expected. Increasing volume should result in more dB. Seems pretty straightforward to me.

Perhaps this is Diracs way of preventing the output signal from clipping due to boost being added when correction is performed. Hopefully someone from EMo will respond.
