So I found some quiet time to finally incorporate DL (full bandwith) into my 3800. Here are the steps I took:
1) Installed DL onto my Windows 10 laptop. The software found my 3800 on the network and I selected it.
2) I attached the UMIK1 to the laptop and proceeded to download the 90 deg calibration file once I put in the serial number for the mic (the other file is better for stereo music).
3) Directed the software to the .txt calibration file and hit Next.
4) I decided to choose the option for "Wide focus" to get my feet wet and have fewer positions to calibrate.
5) Got a "Msg 210, error code 106" that claimed there was too much ambient sound. I increased the mic input on Windows to 100% and proceeded to increase master volume on the 3800 to -40, which did the trick!
6) I measured only 5 positions, center, 2 to the right of center, and 2 to the left of center.
7) I noticed the subwoofer wasn't emitting any pink noises so I increased the dial to give something for the mic to read. I noticed the amplitudes of the SW during the calibration were a bit higher than the rest of the speakers (will fix in next attempt).
8) I studied the curves for each speaker and proposed filters. I exported them to the 3800.
9) Listened to Rebel Moon (scene where the drednought ship enters the atmosphere) and noticed the mid-bass was missing! I suspected this would happen because the handoff from the LFE to the actual speakers were bad according to the curves.
Current theory: I believe the speaker distances and LFE crossovers are inherited from the prior Audyssey calibration (someone please correct if I'm wrong). As such, Audyssey had determined that my L/C/R speakers should have a 260 Hz crossover and my surrounds should be 60 Hz. I've kept this setting since but was hoping to see what impact it would have on Dirac. Unless someone says otherwise, I'm planning to update the crossovers to 80 Hz for all speakers and rerun Dirac. Thoughts?
