DL4 DURAPLEX OMNIDIRECTIONAL

WATERPROOF LAVALIER MICROPHONE

OVERVIEW

Available in lavalier or headset form, DuraPlex has been extensively tested to ensure an IP57 dust-resistant,

waterproof rating. Whether shooting reality TV, mounting a professional theatrical tour, or wherever audio takes

you, contending with the elements won’t slow you down. As comfortable on the beach as it is in a broadcast

studio, DuraPlex features a neutral, full sound quality that lives up to the highest audio standards.

The advanced 1.6 mm Shure Plex cable, ﬁrst introduced with the award-winning TwinPlex subminiature

microphone, lasts longer than competing cables due to a dual redundant ground which doubles as a secondary

shield. It also offers virtually zero “memory effect,” won’t kink, and is fully paintable.
