Thx for the explanation. For better resutls, I keep the Optimizer time run to 2 and test out. After completion, the message dialog comes up asking to keep or discard. Since its a message dialog, there is no way to view the results in detail before clicking yes. So my only option is to click Yes and then observe and then Rest. To Reset, I close the file and open it. I think it'd be a great feature if we can add a Reset button.
Here is another interesting observation (rather concerning). I made a 5 point optimization last night. After optimization, I Reset Gain/Delay. Then when I checked delays on each channel (4 channels), I noticed that channel 3 has a delay of 40. The reason that this is rather concerning is based on the sub location. Here is my setup
Channel 1: 1 Sub located 75" away from MLP on left side
Channel 2: 1 Sub located 75" away from MLP on right side
Channel 3: 2 Subs 165" away from MLP
Channel 4: 2 Subs 165" away from MLP
Subs for channel 3 are sitting on top of subs for Channel 4. The only difference is that Channel 4 subs are oriented to the back wall and Channel 3 subs are oriented to sides walls. Channel 1 which is 75" away has a delay of 4.x and channel 3 has a delay of 40 and Channel 4 has no delay. That's a big difference specially b/w channel 3 Vs channel 4. Should I be worried? I mean could it be a possibility that this is an indication of something is wrong with my setup? Generally, the farthest sub shouldn't have any delay and channel 4 has none (which is correct) but channel 3 sitting right on top of channel 4 subs has 40
I took readings of subs in REW with acoustic timing reference signal for each signal. Same speaker (Left) was used for all the readings. I had subs distance set to 0. Only possible confusion/concern with my setup is that I have 88-a (Dirac) in the chain. It was disabled though. But even when its disabled, it keeps the delay. So wondering if its the delay caused by 88-a that's making Channel 3 to be 40.
Or I have nothing to be worried about?
