I like the way this trend is going. You remember a few months ago I complained because no one was making a live digital mixing system that put the converters on stage, used a cat5 cable, and would feed separate tracks into your computer for simultaneous recording? And then how people jumped all over that, saying it can't be done?
We said it could be done - just not cheaply. And that thing ain't
cheap... $13k.

Well, it looks like Mackie is selling that system right now, and it's at a fairly reasonable price, sure to come down in the future:

Maybe Mackie becomes the low-cost leader in what is certain to be the future of live sound. I wonder if they can talk Aviom into letting them do the A16, too, and make it affordable for us mere mortals?
Other than the cable diameter, what's the point?

No added hum or noise,

Maybe. You still have to run a power cable or you'll
have ground loops. I had a ground loop last weekend from two
boxes with conduit between 'em - explain *that*.

You're suggesting ground loops over cat5 cable??? I don't think so, but I couldn't prove it either way.


I am remembering that it might be possible. I can't give
any more detail than that, unfortunately. I would not
assume it cannot happen, and if called upon to be responsible
for such a device, I would get my story very straight.

Theoretically, all the pairs should be purely balanced and
you should not have any ground loops. The cable end of the
Cat 5 should also be a long ways away electrically
from case, signal or board grounds.

"Shouldn't" - yes. "Doesn't" - dunno.



even in electrically noisy environments, no loss of audio signal level,


Okay then...

and the cable diameter and weight differences really come into play as you expand up to the 96 channel maximum.


*96* channels? How in blazes is anybody gonna use
96 channels in a live setting??? 16 is nigh on
unmanageable...


It's called "scenes". 96 does seem a bit hight, but 16 is a bit low.

True. Sheesh - 96 things mixed together gives an average level
of close to -20dB. Obviously, some of those will be quiet some
of the time. If that's in 16 bit space with 20dB
headroom ( I doubt it) then the noise floor for digital - not
even the summed noise of analog - is a mere -56dB below that.

Just sayin...

Now, I don't personally use a rig this big, but as I understand it, you set up a balance say for the lead singer to sing on top of the mix and we might call it "vocal". Then you set up a scene re-balanced for a violin lead. You reset everything until you have it just right and you record the scene. Then you have a piano break - yep another scene. Now when all this come up live the sound guy just selects the appropriate scene at the appropriate time although if they are running any kind of sequence it changes the scenes for them. In actual use it is amazing.


Interesting. I am sure that for large productions, "chunking' things
like that is required.

Wireless, even high-directivity optical
wireless, I can see.
