Setting the Limiters
Here is a calculator that will provide the maximum limiter settings that should be allowed. The power and impedance values that you need to enter can be found in the specifications on the individual product pages.
*Important: Your limiter setting should NEVER exceed this value (i.e. be made less sensitive) and neither should it be fully relied on to protect the system. The final responsibility lies with the operator, only the person who stands in front of the system can tell what is really happening.
If you stay within the power of the attached table, 'follow the notes' and tighten limiters further to set an acceptable level which sounds sweet, you will almost certainly find yourself turning some of the limiters down below the speaker's power ratings.
Once you have the system up and running the most important thing is to listen to the speakers, they'll tell you if they're getting too much power as they start to sound bad, generally a speaker will start to distort long before it actually destroys itself. If a bass speaker starts to "growl" then its reaching its mechanical limits and producing second harmonic distortion, so it needs to be turned down or limited earlier if you can't control the maximum level with the fader (i.e. if the DJ is "in control"...)
