Eminence Speaker D-Fend SA300

Eminence Speaker’s new D-fend™ SA300 is a fully programmable stand-alone unit designed to protect 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 fire caused by excessive heat. Not only does D-fend keep systems safe, but venues and audiences 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. Operating from a standard speaker-level signal, the D-fend SA300 requires no auxiliary power unless being used in lowpower applications. D-fend loudspeaker protection is ideal for system installers, PA gear rental companies, OEM manufacturers, and any end-users who own passive loudspeakers. Retail price: $209.99.
