bit off topic but is the sound quality noticeably better on the xta units? Anyone compared them?

No , nothing in it! 

I have had the chance to a/b them ( martin dx1.5 / xp4080 ) ! 

Just my view now and i have in no way a trained ear , but i did notice the difference when i 
moved from the dbx to the xilica .

people have criticised the xilica limiters, and praised the xta limiters. i haven't lost anything that's been behind a xilica limiter yet, nor xta..

i haven't any real criticism of the xilica limiters.

The sound of the xta limiter is the sound of Funktion one!
LOL! -That's sucks, but it's often like that in Denmark.

If you are RELYING on the output limiters on these devices,  you are definitely doing yourself a disfavor.

The perfect setup for these is to use a Drawmer Speaker Protector,  as this stops all the assholes that scream into mics on the DJM 900.  This solves 95% of all service call problems.

The input is amazing as BSS, XTA, Ashley and others have no headroom.   I'm talking high end install.  The xilica allows me to just hit -14 on my input and BOOM  I have days of headroom to play with. 

Input compressor is set to quick attack like a limiter and 10:1  to catch abusive quick things.  And then I can almost always run my output limiters normally and they just catch the extra transients under HEAVY abuse situations. 

I can't speak highly enough of these the XD and the UNO series.  I have installed nearly 100 here in the USA and a couple in Mexico.  I have also been a key player in rewriting all the Uno software and GUI for the last 2 years.  As I installed the first unit ever,  and had to send them back 2 pages of bug notes.  We now in the Uno platform have a remarkable sounding easy to use DSP.  And at 1/2 the price of BSS, Biamp, and others,  I also think is sounds much better. 

P.S.  always remember to use a router , not just a switch...

I recently picked up a XP 8080 from ebay what can i use all the inputs for ?...also what model does the void 'digidrives' come under.  Thanks.

The 'drunken master' strikes again.

Regarding the limiters: if you really have to RELY on the limiters, meaning that they must protect against short term mechanical damage as well as long term overheating, you must know EXACTLY how they work.
In the case of the Xilica XP series, there is absolutely ZERO info in the manual and datasheet about the limiter mechanism.
Since we bought a XP-4080, we have been doing loopback measurements on the device.
 
This is a sine wave at 100hz, recorded in Audacity:
 
 
This is how the sine wave is cut off when setting an output limiter on the Xilica with a 100ms attack:
 
 
This is with a 10ms attack:
 
 
You cannot set the attack too low though, or the limiter will actually cut into the waveform, which will result in distorted sound:
 
 
Now as for the final test, we test how it responds to signals with vastly different density (music signal vs sine):
 
 
As we can see, it cuts off at a fixed point. So it is a pure PEAK limiter. If it had an RMS limiter function, it would cut off differently with varying signal density.
 
If you don't understand the difference, a peak limiter ONLY protects against short term mechanical damage. It will only cut of the peaks of the signal. If you increase the input, the peaks will be cut off, but the signal density will increase, meaning the average power going to the speakers, along with heat generated in the voice coil, will increase.
All in all, the limiter in the Xilica XP series does NOT completely protect the speakers!
 
 
Regarding sound quality: this is the reason we bought the XP-4080.
Before it, we had tested the Behringer DCX-2496, and several dbx driveracks (PA, PA+, PA2, Venu360). All of those had audible signal degradation. The DCX generally sounded a little flat, the PA and PA+ were missing definition in the highs, and with the PA2 and Venu360 basically everything was wrong.
 
The Xilica XP series is the only DSP so far that, when we put it in the signal chain, cannot hear the difference. Highly recommended!
