Which often times people don't realize that you can use stagebox inputs for those aux channels too. Especially when you are running an M32c which has no useful i/O. When you have filled the mixer with 32ch of XLR mic inputs you still can use the aux inputs for cascading another mixer via aes50 as well as a couple stereo playback lines without using up any of those primary 32.
Thanks, Craig, I've kind of forgotten about this, although I think you've named almost the only uses for this ability, given that you have no Dynamics and other diminished control on those channels, although they're fine for those purposes.
Regarding the channel count, the X and M series consoles use one version of AES50 (SuperMax or something like that) which maxes out at 48kHz sampling rate and 48 channels each way (which is why you can have 32 split channels and 16 Mixbuses sent between 2 connected consoles, although only that still leaves 16 unused channels going one direction--not sure why they did that, although I confess I'm having trouble right now keeping this straight in my head -- long day), while the upper version is HyperMax or something like that, which has a higher channel count (not sure what that is, don't have any consoles that use it --they're the Pro series and I presume whatever's replaced that) and 96kHz sampling rate, maybe higher now.
That's enough for now to differentiate between the two versions.
Not sure where the Wing fits in, I believe others here can help on that.
I guess Jeff and I will have to throw down out back...
