TwinPlex™ Lavalier Microphones
General Description
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.
