BTW this thread is more than a year old, instead of hijacking a thread please consider starting a new one... this way lurkers can also learn more..
I think perhaps a difference of culture perhaps here? I was NOT even "gently scolding" you but trying to indicate how forum decorum is conducted. Fact is, the posters here usually get what they need and are never heard from again. Further, we have to scroll through a bunch of text and posts to get to the questions AND have to go back and re-read what the OP wrote to get the whole gist of what's being discussed...
Had you posted this way in a forum like the PSW.... you would have come away with significant scalding...
I even said "please"
If you follow my posts you will find that as moderators go (yes I'm a moderator here) I leave a wide latitude here in all things.
So, to translate that, would my amp rated at 200 watts be reduced by 1.5dB or so?
What I'm trying to ask is how do I translate 400 watt program into a dB setting on the driverack and a 200watt amp?
Or do I use an amp with a higher power rating?
The thing here is that with a limiter such as the Driveracks, has a number of controls that allow you to customize how much, and how hard the limiters affect the program material. Part of what I wrote to you suggested you do a proper gain structure which will reveal where all the equipment naturally clips, and as I am, often heard to say... your far better off to let the gain structure , and natural clipping point be the determining factor for normal operation, and let the limiter be an OOPS/// I dropped the mic kind of protection.
In this case your probably better off cranking the amps, setting a brick wall limiter and then playing the type of music played, then with the amps lightly clipping dial down the threshold till no clipping is present, no matter where the master faders end up...
***NOTE*** this method can result in a higher amp duty cycle! Which can heat up voice coils! This also allows the master faders to be part of the problem here...
The BEST way to insure you have something left AFTER DJ's run your stuff is to threaten to KILL them... (sorry.. I digress) no actually to use the gain structure method, where the mixer AND amps are set to clip together, then lower the amps input sensitivity till the amps are no longer clipping, and perhaps a bit more for headroom, then put tamper proof covers on the amps and THEN set the brick wall limiter for OOPS protection.
No scolding, no telling off... just logical assertions that help keep the forum running smoothly, making it easier for us old sound guys to comprehend and answer the myriad of questions posted here.
