Phantom Premiere and Dante

[mingfang]

@mingfang Hi!  Were you able to test out Dirac?  Did it provide an improvement?  How are the tone controls?  Are you able to tune the system?

I just did a quick run of DirecLive 3. I did encounter a few hiccups but it eventually worked and I got good results.

Here is my updated setup.
Fronts: SDP-55 -> Devialet Dante adapter -> Devialet Silver in Optical Direct mode , 1 ms latency
Center: SDP-55 -> Devialet Dante adapter - > Devialet Reactor 900, 60 ms latency Reactor 900 Custom w/Built-in Dante, 1 ms latency
Sub: SDP-55 -> Audinate Dante to XLR adapter -> MartinLogan Descent-i subwoofer

Calibration:
1-Connect the included USB calibration mic to my MacBook
2-Upon openning the DirecLive app, it will discover the JBL SDP-55 on the network
3-The first screen in the guided process is to adjust the volume of each speaker to about the same level
4-Then you choose between focused or diffused center.  I picked diffused for family viewing
5-Then it guides you to measure up to 17 positions, it plays a calibration tone cycling to each speaker.
    I did it for the first 3 positions(center, left, right) and opted to skipped the rest.
6-The measured results are displayed in a graph and I think you can adjust by dragging the line of the graph.  I left it alone.
7-Finally you save the results to any of the 3 slots on the JBL SDP-55. 
   This step was not smooth.  The SDP-55 appears to freeze/lock up with the status of "saving" or "exiting" from the Direc mode.
   I had to physically power cycle the SDP-55 and then it worked.
8-To use the Direc results, you have to navigate to the each input on the SDP-55's web interface and choose the slot you saved in step #7
9-When Direc is active, you can't change the speaker type(large vs small). 
   But you can still adjust each speaker's distance and volume.
   
The result is good. I toggle Direc on and off to hear the difference and it is better with it on.
