Forgive me for reading yesterday's newspaper today, but I finally got around to updating my UX8800 and am using Single Mode. What a huge improvement - both in terms of making conceptual sense of how the processor works, as well as greatly increasing the number of things a UX8800 can likely drive at once - greyboxes don't have to be assigned on "input" channels, but rather "output" channels. For single amped systems like my current configuration, that means I have a lot of drive lines left for various fills that I didn't have before.
 
Re: UX8800 Single Mode

Hm,

I guess I need to get with the program also. I got an install that looks like it can take advantage of the extra options.

I'd even had a version of EAW pilot downloaded that had Single Mode but hadn't noticed it.

Don't you both love and hate how now need to worry about keeping our gear's firmware/software up to date? :)

Re: UX8800 Single Mode

Ok, I don't have any EAW stuff but...what the heck is "Single Mode" for those of us who just like to learn stuff here?

thanks
Previously, UX8800s had 2 main operating modes - system processing mode, and greybox mode. In regular system processing mode, the UX8800 behaves pretty much like any 4X8 processor - full control over signal assignment, filters, etc.

Greybox mode enabled all the cool stuff invented by Dave Gunness, and packaged those relevant settings into "greyboxes" - a baseline set of processing containing speaker correction elements that could not be touched by the end user. You still had EQ and delay control, but it is partially locked down, hence the "grey" box.

The quirk of how this was implemented previously, is that a greyboxe had to be set on your input processing channels, and the routing was determined from there. If you had a 3-way box, your greybox for that speaker would be assigned to input A, and outputs 1, 2, and 3 would be taken by that greybox, and so on.

The downside came when you have boxes with fewer bands, or for when you are using the internal crossovers of those boxes; you could run out of inputs before you used all your outputs. In my particular case, my main speakers are running single-amped. Input A was used up for left, assigned to output 1. Input B was used up for right, assigned to output 2. My subs - even if I ran stereo mode and not aux/group fed - took up "Input" C, since that's where the greybox lives, even though it got its signal from the sum of input jack A and B. I was left with only one input channel, and 5 output channels. I basically had a 4 X 4 processor.

In single mode, greyboxes are now assigned on output channels, and it's easier to mix greybox and non-greybox operation. My new configuration is now: Input A is left main, Input B is right main. Greyboxes for mains are on outputs 1 and 2, and the subs greybox is on output 3, fed from inputs A and B. I now have 2 of my 4 inputs available, and furthermore I can assign more greyboxes for delay fills, etc. that use up my output channels while still maintaining the cool processing.
