11. following section describes how to set up the units limiters to provide exceptional protection against driver overheating and cone over excursion Most speaker systems are given a power rating in Watts RMS This is the maximum continuous power that the system will handle and often appears very conservative In reality as music program is far from continuous in nature the peak power of the system is much higher up to ten times the continuous figure Any limiter which is to protect the driver from damage must be able to fulfil the following tasks e Have an attack time which is calculated to allow transients through but keep the RMS level below the speaker manufacturer s specification e Have a release time which is sufficiently long to avoid the limiter itself modulating the program e Be intelligent enough to adjust the envelope of the limiter according to the frequency content of the program material The program limiters are capable of performing all these tasks The only parameter that the user must set manually is the threshold and it is crucial that this is done correctly Consider the table below Pwr 2 Q 9486 83 7535 66 5985 79 4754 68 3776 78 3000 00 Vrms Pwr 8 Q Pwr 4 Q 13774 237171 474342 3767 83 2992 89 2377 34 1888 39 1500 00 1191 49 946 44 751 78 597 16 2382 98 1892 87 1503 56 1194 32 948 68 474 34 376 78 753 57 299 29 598 58 237

13. just set for safety the system is capable of being driven into a state of imbalance where it sounds bad and can even be way too loud for the venue and the safety of the people in it Bass speakers these days can handle a massive amount of power as long as it s clean so large amps are used and limiters set to stop clip from occurring Mid and high limiters are set progressively tighter in respect to the drivers lesser power handling It s still a good idea to use a large amp though Transient spikes totally valid to the music like the hit of the snare or cymbal crashes can get past the limiters and this is good because the dynamics and excitement of the music are preserved and these transients are not long enough to overpower the driver as long as they re not clipping So what happens as the system comes up to full power Often the bass will limit first then as the system is driven harder the low mid starts to limit the high mids are still going strong as are the highs If the bass limits 4 dB before the mid highs this is effectively the same as turning up the mid highs by 4dB the balance of the system is completely wrong and all the hard work of tuning and sound check is wasted The thing to do here is to tighten the limiters still further so that the mids and highs start to limit at around the same point as the bass This way the frequency content of the music will be maintained when in the limiters the mids stay at a level where they still relate t
