(edited to attach freq response measurements screenshots from Dirac for each speaker) \n\nHi All,\n\nThere's a lot to unpack here. If I should make separate threads please advise.\n\nSpeaker Configuration: 5.1.2\nAVR: Onkyo TX-RZ50\nRoom EQ Dirac Live latest version 3.3.3\nSystem OS: macOS Monterey\nMeasurement Mic: UMIK-1\n\nProblem:\n Previously I had a Denon receiver and used Audyssey EQ. As a newcomer with untrained ears. It sounded great to me. I knew I was bottlenecking my system though with the receiver I had (S760 75W, 2channels) so I decided to get a Onkyo TX-RZ50 with a larger amp and preouts. I set it up. Installed Dirac on my Mac watched and read numerous "How to use Dirac Live" tutorials. I tried it for the first time, not really understanding the volume calibration that well, and it was lifeless. If the Audessey + Denon was a 6.5\/10, Dirac Live + Onkyo sounded subjectively to me like a 2.5\/10. My speakers were sounded quieter, my surrounds were almost non existent, and I had zero bass. I downloaded and applied a +10db Lowfreq Harman target curve to all channels and still did not hear any presence of bass or life and color to my L,R,C and surrounds the seemed to sound flat. I level matched my speakers in the Onkyo setup tool but still not much improvement. I know it could be a multitude of things, but I'm learning towards Dirac Live and error on my part for something.\n\nI'm not sure what is going on, would anyone be able to give me some things to look into and try?\n\nOn to understanding Dirac Live Volume Cal. After connecting my UMIK-1 and loading the 90degree cal file. I get to the volume calibration screen. I set the master Volume low and Mic gain to +18dB. First of all. I don't understand if I should be setting Mic Gain. On the input selection in Dirac Live the UMIK shows 18dB. In tutorials I've watched and read, the mic gain is set to 100%. I don't really know what I should be setting that to. When I click play on any of the speakers I have to increase my Master volume by what seems like a unnecessary amount The readout of a SPL meter is usually 85dB or higher to see any kind of reading and the reading is usually very low at -45dB when I play the noise from each speaker. Why is this? I've watched other videos and tutorials and they say use a "comfortable listening volume" Then I see their readings for speakers at -25dB or even -16dB. The way I've been able to achieve a reading from my sub is to set the gain to zero on the sub, then after matching the other speakers to around -43dB I use the sub gain to increase gain which usually would go from -60 all the way to -9 to achieve -43dB. I feel like my microphone is not reading something right or I have a giant misunderstanding or setup something incorrectly. I'm also curious to know if this would effect my experience after doing the measurements and applying it to a slot in my receiver. I feel like I am missing several things here. Anyone have some gotchas or newbie mistakes that I'm probably making?\n\nThanks for taking the time to read and help!
