All depends on the program material, and the person driving the input to the DCX. |

i originally thought that the berry limiters wouldnt do the job, but i was wrong.
Set up correctly i've had a dj spank the living daylights out of a mixer with the limit lights on solidly for hours and provided you've set the limiters correctly nothing gets toasted. ok it sounds a bit crap when being abused so heavily, but you just cant tell some people. i know how to set the limit for the system its running, and its absolutely fine.

If you bring the channel gains up on the input section then the signal will be at a higher level where it enters the limiter, meaning the threshold can be set effectively. If the DCX output is then too strong for the amp, turn the output channel gains down. |

The 4000mS for system protection is ideal. You dont want it much shorter or it'll come out of gain reduction before the thing that triggered it has gone! The unwanted result would be dynamic compression or system pumping which could stress the sound system more, not less.

Are you sure? I've just tried to set the limiters and find that the amp clips before the limiters come on, even set at a minmium threshold. Using what you said and turning the input gain up and the output gain down, it appears that turning down the output gain down stops the limiter from coming on at all.

Im also new to all of this, but should it not be the other way around? The signal reaches the output gain first and then the xover,eq limiter etc. at least thats what the manual says.So I think a higher output gain would be more beneficial to let the limiter cut the signal.

In my V1.1 manual on disc it shows the output gain as being before the limiter in the block diagram, so what you say happens I'd agree with. But I've played to my hearts content with a couple here and in installs and the output gain hasn't altered the level that drives the limiter. Maybe there are different firmware versions around? |

We have 2 DCX's and the limiters are fine better if set correct. Nothing is better than good old fashion standing behind the foh console turning it down tho IMHO.
Before I have put a note on the decks saying if you red line it hard I will turn the monitors off, Turn them off and watch the level come down! Jace |
