    General Description

    Four lavaliers in white, cocoa, tan, and black

    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.

    Note: The regulatory model numbers for these devices are TL46B/O, TL47B/O, and TL48B/O.

    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.

    Hirose Wiring for Sony Bodypacks

    Notes:

    • When using TwinPlex mics with Sony Hirose 4-pin bodypacks, Shure recommends purchasing Shure –MTQG versions and not –NC versions. This facilitates an easier termination due to the lack of circuitry required in Shure 3-wire/MTQG TA4F products.
    • Due to the thin cable on TwinPlex and the large boot on Hirose connectors, heat shrink may be required to build up the cable under the boot where the crimp connection is made and where the cable exits the boot
    • The TwinPlex Microdot (-MDOT) version can be used with 4-pin Hirose adapters from DPA (DPA part # DAD6008)

    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.
