class. The TwinPlex series features the most extensive accessories and connector options to date. TwinPlex 5 mm lavs not

The Shure TwinPlex Cartridge
Over 6 years in development, the patent pending, TwinPlex Omnidirectional element was designed to offer best in class sound
quality and specifications of any lavalier to date. It utilizes a dual-diaphragm design with two side firing elements as opposed to
a single, end fired design. By essentially doubling the surface area of the diaphragm in the same amount of space, the
TwinPlex design offers robust low frequency response, exceptional off-axis consistency, increased gain-before-feedback and
low handling noise, resulting in a new tier of performance for 5mm microphones.

Care and Maintenance
The TwinPlex lavalier dual-diaphragm has a nanocoating which rejects the build-up of grit from sweat and water. It is designed
to withstand being blown out with a can of air for quick clean-up.
