Does this look familiar? Replacing HF diaphragms in your system again!
It
is not only the cost, it’s also the hassle factor and the problem
of the sound system sounding muffled during a show.
The problem with nearly all passive and active loudspeaker systems is the high frequency compression driver (tweeters/horns), these are by there very nature highly vulnerable to damage and failure.
Apart from badly overdriven clipped systems, a major cause is that modern digital audio techniques use copious amounts of compression, which can in nearly all cases more than double the average voltage being fed into a loudspeaker system.
Most of the major companies now try to protect their products by fitting a bulb in parallel with a ballast resistor or poly-switch (PTC = resettable fuse), but both these methods have limited success, because the bulb invariably blows putting the entire load through the resistor which eventually fails as well; PTC’s also suffer from progressive switching fatigue - they trip earlier & earlier and at a lower power each time
The TWEETAGUARD is a solid state device that monitors the average RMS/AES voltage of the power going to a high frequency driver and if it exceeds the set level it will shut off the feed preventing any damage to the unit.
