In the digital domain is not everything represented by just a number? (or well a sequence of bits that represent a number). If that's the case, digital clipping occurs when you've reached the "biggest number" that the system allows. So ultimately, just make the "biggest number" even bigger and then you should have ungodly amounts of internal gain before clipping, and then at output time, just attenuate things back down to reasonable analog output levels. I suppose this would cost more, as instead of having say a 16 bit or 24 bit signal path, you might now need 32 bit and the components and such would be more expensive...but at least you'd have gobs of headroom right?


It took me a while to find what post you were responding to..

Yes, inside the digital domain you can add more bits with each extra bit doubling the dynamic range, or use floating point math where you have a fixed resolution and scale that up or down for near infinite headroom.

More useful for real time live use to apply limiting or clip at the point of overload, relative to full scale.

It is appropriate and useful to build in some digital headroom for processes that need it, but in some ways this problem is the same as in analog consoles. You headroom is ultimately defined by the output. While I guess you can always do worse than that.
------
In response to Bennet's specific complaint.. I see two possible mitigations. If there are some extra artifacts being generated beyond simple clipping, Some effects can have have math headroom issues. it seems software tweaks should be able to improve that.

Regarding the problem of having to page through multiple layers to find the offending control, one idea I had a long time ago was to have the control surface snap to the channel or layer when it detects audibly significant overload.  This feature might be distracting to some, so should be user optional. I never ended up pursuing that project so there may be practical problems with just adding this to a finished hardware implementation.

One very powerful benefit about operating in the digital domain is the ability to incorporate nonlinear decision making to help us much slower humans.

Have you found yourself having more fun mixing with this console than usual?


Cheers and have fun.

Hey Toby,

Good to see you around!

Are you still doing IEM/Monitors for Jimmy Barnes?

Think last time i saw you was over here at an outdoor fest on the central coast ??

The roadcases with the I-Live are very high quality.
The only thing (which I believe they have now addressed) were the wheel locks on mine failed.



We had our iLive delivered with the same kind of flimsy wheel locks. A&H were happy to supply us with decent ones free of charge. The cases are excellent, they will last a lifetime.

I've been asked to stand in at a church for the next few weeks to give the regular guy a break,    they have a brand new Ilive 80. Today was my first shot at it and I have to agree with most everything that Bennett said in his review.  I was using a patch and configuration that was already set however it didn't take much to see how I could alter things to suit my taste and way of working. The one thing that could catch you out till your used to it is mixing away happily only to discover that you are on a different mix (aux out or FX send) Only nearly happened once during the service but when I was getting the 10 cent tour it happened a couple of times.
Overall it seems a good system and at least with the small console it would be no problem to move single handed as long as there aren't too many stairs, though I do wonder what the SD8 is going to do to its market.
One question is it possible to delay the local monitor output as the desk is stuck away in a really awkward position largely out of the sound field of the speakers and I was thinking of tsking in some near field speakers, running the system by laptop isn't an option just now as there are several cd track playing cues most services and a recorder needs to be started for the preach

Gordon, yes it is possible to add delay to the local PFL/IEM monitor mix.

Under PFL there is a Delay tab, you can choose between feet (with temp compensation) MS or Meters.


If when you have an AUX or an FX selected, if you push the routing button under the touch screen.

you will see a Routing view for the Aux or the FX whichever you have selected, on the right hand side of the touch screen there is a touch button called "mix on rotaries" if you press that (per FX or PER AUX) it will put the Aux Mix or the FX mix on the rotary encoders above each channel, instead of the send  being on the faders.

My preference is to put Aux's send on faders and FX sends on rotaries, but that is just my preference.

Thanks Mike, I'll give the nearfields a shot next time, the mix button thing will probably not be an issue as long as I pay attention, I don't want to change too much as I'm only doing this for about 6 weeks or so. The church band have a rehearsal on Thursday so I get to go and play more in a less pressured situation .  Liking the desk so far, just wish the church had thought about its install, just now its like buying a 50" TV then standing behind it and watching the screen on a mirror at the other side of the room.  Hopefully I won't have to do too much as every thing is more or less patched etc, though Christmas is coming along with the inevitable "special" service so it may be a "Wish me luck Scotty" scenario next Sunday evening.

So Bennett
having now road tested the I-Live and the Profile.
Which was your favourite.
