[QUOTE="Brian jojade, post: 147645, member: 211"] Re: Speaker protection The only way to guarantee not blowing up a speaker is to limit the power to half the RMS rating of the speaker. The reason the limited power has to be half, is that the RMS power is rated with a sine wave. If you drive hard into clipping, the wave becomes more of a square wave. A square wave of the same voltage as a sine wave is twice the actual power. Now, if you've got to set a limiter THAT stringently for protection, then you've got some complete idiots working the equipment. Usually, you can get away with running program power, which is twice that of RMS. With most musical programs the dynamics of the music will mean the average overall power remains below RMS. However, again, if you put a limiter in and you push past the limiter, the average power shoots up, and stuff can blow. Oh, and peak and program ratings are just numbers used by the marketing team to make things sound bigger than they are. RMS power is the only number you really need to know. [/QUOTE]
