Eminence Speaker’s D-fend SA300 is a loudspeaker protection and attenuation microprocessor that monitors and limits the amount of input power passed to a loudspeaker with user-adjustable settings for attack, release, and threshold. Operating from a standard speaker-level signal, it requires no auxiliary power unless being used in low-power applications. Its settings can be customized using a desktop or laptop.
