And to present the other side to this argument, I’ve managed to remove our outboard system processing completely, such that the iLive system does everything. And it works very nicely. I run high/low pass on L, R and SUB main mixes, then run those into matrices to do speaker-based EQ, limiting and delays. Very easy to manage, and sounds much cleaner, more dynamic and with a better signal-to-noise ratio than I had previously achieved with our (admittedly low-to-mid-budget) analogue kit. Mine is a permanently-installed system that requires occasional flexibility, so if you’re touring or hiring your system your mileage might vary.
Needless to say I’m still really, really impressed with my new purchase!
