It an 8 zone system with a dedicated home theater room. Mixture of high end in wall/ceiling speakers and outdoor speakers. The DJ function is for parties ones or twice a year. I really need something basic strictly to protect the system against mike issues or an over enthusiastic DJ.
One issue I have dealt with for years is the mic.
They are normally run by the DJ through the crap mic input built into the mixer.
So even if you provide a perfectly EQ'd, shaped and compressed separate microphone, they will always pull out their own, stab it into the garbage mic input installed in every DJ mixer currently available and proceed to remove every "high end" dome tweeter throughout the home.
The main problem with using the mixer's input is that after you limit and control the output of it to protect the system from musical abuses, there's no gain headroom left for a talkover mic -usually the limiter just piles-on more gain reduction.
All that limiting always results in the operators boosting the mic channel to the normally clipped and distorted, cupped-mic, yelled-into sound we all know and loathe.
Unfortunately once the vocalizing stops, the limiter opens back up and the mic feeds back hard! Really hard and for a long time too -as all the happy drunk people have no idea what is going on and what they did wrong!
The only success I've ever had in dealing with this (and I've had to a lot over the years) Is to install a system that is so eye-wateringly loud and capable, that the limiter is set so far beyond what any sane person drunk or sober would ever run the system at -and if they did it would be "limited" by local law enforcement long before damage occurs.
Usually such a system just kind of happens as an upgrade process after the client blows up the original design one or two times first.
