Eminence Speaker LLC Offers the Ultimate Loudspeaker Protection to
Pro Audio and MI Markets

 
Eminence, KY – Eminence Speaker LLC proudly announces an exclusive license agreement with
Evenstar, a wholly owned subsidiary of SLS Audio, to use and sub-license their revolutionary new
D-fendtechnology within the Professional Audio and Musical Instrument markets.

D-fend™ is the industry’s first all-digital, programmable loudspeaker protection and attenuation
circuit designed to solve the age-old problems associated with protecting loudspeakers from excessive power conditions. D-fend™ has eliminated the headaches for speaker engineers - no more hassling with polyswitches, blown lamp filaments, lossy resistors, or slow relays. Incorporating such features as digital signal processing with on-board digital filtering, customizable microprocessor and MOSFET construction, the D-fend™ protection circuit enables a designer to use this technology prior to passive filtration and allows different sensitivity settings in specific frequency bands, such as woofer over-excursion bands or high frequency peak damage regions.

“Think of the D-fend circuit as a high power, speaker-level compressor/limiter that will allow
an audio designer to guarantee unmatched levels of protection for multiple components in their
unpowered loudspeakers”, states Evenstar’s Chief Engineer, Joel Butler.

“We’re are very excited about the unique opportunity to partner with Evenstar to offer our customers
the ultimate in loudspeaker protection.” said Eminence President Chris Rose. “Not even the most
carefully designed systems have been free of failure and the risk of thermal compromises in today’s
varied applications. By incorporating D-fend in their products, system designers, brand owners
and facilities will enjoy a new level of assurance that their passive loudspeaker systems will remain
protected and that venues will be safer. The technology is economical and easy to integrate into
both new and existing designs. We expect it will become an industry standard protection device for
virtually all passive professional audio and musical instrument applications.”

See the D-fend™ technology in action at the Eminence InfoComm booth #164 in Orlando, Florida
June 15 - 17, 2011, or inquire to dfend@eminence.com for more information.
