D-fend™ is designed to solve the age-old problems associated with protecting passive loudspeakers from excessive power conditions. A patent-pending technology, D-fend™ allows maximum driver performance while ensuring damage-free operation.
With D-fend there are no more worries about blown speakers, HF drivers or crossovers. Or even worse: fire caused by excessive heat. Not only does D-fend keep your system safe, but your venue and audience as well. The user simply sets the thresholds and D-fend monitors and limits the amount of input power it passes through to the loudspeaker. It’s USB compatible, and can be programmed to your specifications from a desktop or laptop. Just set it and forget it. Protect your products, venue, customers, and your reputation with the first passive speaker protection system that is virtually indestructible.
D-fend loudspeaker protection is ideal for:
InstallersWord of mouth can be an installer’s best friend or worst enemy. D-fend will not only protect your carefully installed equipment, but also gives you peace of mind knowing your reputation is protected as well.
By using D-fend you can rent out your speakers and know that you’ll get them back in the same condition they left. So what comes in on Monday can go back out the door again without a visit to your repair shop.
Own some passive speakers? Chances are you’ve come closer than you think to blowing a driver. There’s nothing worse than stopping a show in progress because you just lost your subwoofer. Why take the chance?
