Tweet A Guard

TweetAGuard is a protective device for compression drivers & Audio Systems H/F devices. The concept of the device is to guard expensive H/F & Mid range transducers against audio abuse. It Applications include: • Stage Monitors
• PA Hire & Dry Hire companies
• Clubs. Discos, Theatres and Arenas
• Any location where expensive equipment needs to be protected
 

A cost effective solution:

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 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.
