So the AVR settings for the speakers, large vs. small, and crossovers have no impact on the calibration. Regardless, if you are going to use the BM add-on, Speakers should be set to large, and trims and distances should be set to zero.
And the settings on the LFE Mgt tab, where all the bass management configuration in the 88A happens, also have no impact on the Dirac calibration. The Dirac block occurs after the bass management block in the signal path.
So, the order of things is, Dirac calibration first, and then configure bass management. This is all covered in the guide.
And Step 3 is wrong. No need to reset the 88A after the calibration. This just erases the calibration you just ran. Why would you want to do this?
Got my snakes in! Got the output all hooked up from the 88A to my amp, and I have an issue but it’s a consistent one.
All my mains (L/R/C) are nearly identical to each other. My surrounds are identical to each other.
My mains are 4ohm with 101 dB sensitivity.
My surrounds are 8ohm with 95dB sensitivity.
My amp is 400x7 at 8ohm, so the mains are getting more juice and they’re more sensitive.
I mention this since it might be responsible for what I’m seeing.
I’m going through Dirac’s test tones to check levels, I get get my mains and subs to line up at -12 +/-2ish with the same output setting. No sweat.
When I run the test tone on my surrounds, it’s the same for all of them, but FAR below the level of everything else.
Prolly minus 18. It’s just baaaarely in the green at all.
What should I do? All the channel volumes are maxed out, so I can’t increase the surrounds.
I could increase the output volume, then lower the channel volume on the mains to match the surrounds? You told me not to do that though.
So I need to crack the unit open and adjust the gain?
