General Description
Shure Incorporated
The Shure TwinPlex subminiature omnidirectional lavaliers are designed to perform better than other 5 mm lavalier
microphones for professional theater, film, tv, and corporate events. The TwinPlex dual-diaphragm technology yields
extraordinary gain-before-feedback, off-axis response, and low self-noise while delivering life-like, exceptional clarity
free of digital interference. The cable itself is ultra quiet and has been tested to be the longest-lasting, most
dependable cable in its class. The TwinPlex series features the most extensive accessories and connector options
to date. TwinPlex 5 mm lavs not only meet premium market-leading expectations, they exceed them.

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.

RPM400 Preamplifiers
The RPM400 preamplifiers offer exceptional dynamic range utilizing an active gain circuit in
a concise and small package. They are offered in two connector versions: TA4F and LEMO,
which allows you to quickly take a wireless TL microphone and make it a wired solution.
These preamplifiers require phantom power and can efficiently operate across a wide range
of supply voltages from 12-48v.
Features
•
Active circuit design with neutral gain mimics wireless for consistent gain output across wired or wireless
applications.
•
High RF immunity against unwanted interference.
•
Short, compact design.
•
Belt clip and table mounting kits for easy placement for a variety of applications.
Preamplifier Mounting Kit
TwinPlex XLR microphones include an under table mounting kit for temporarily or permanently mounting the
amplifier. It includes preamplifier clip, 4 screws, and premium dual lock adhesive. The mounting kit and accessories
are also sold separately.
