Product Usage Instructions: TwinPlex Lavalier Microphones

Before using the TwinPlex Lavalier Microphone, make sure it is properly connected to your recording device or amplifier. Refer to the wiring and termination section of the user manual for detailed instructions on how to wire and connect the microphone.

Attaching Accessories

The TwinPlex Lavalier Microphones are designed to be versatile and can be mounted in various ways depending on your needs. Refer to the user manual for detailed instructions on how to attach accessories, such as windscreens, clips, and mounts.

Using the Microphone

When using the TwinPlex Lavalier Microphone, make sure it is positioned correctly to capture clear audio. The specific positioning will depend on the type of recording you are making and the environment in which you are recording. Experiment with different positions to find the best one for your needs.

When recording, it is important to speak clearly and at a consistent volume. Avoid moving the microphone or rustling clothing, as this can create unwanted noise. Always monitor your audio levels to ensure you are capturing high- quality audio.

After use, store the microphone in a safe and dry location. Avoid exposing it to extreme temperatures or conditions that may damage the microphone.

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 gain­before­feedback, off­axis response, and low self­noise while delivering life­like, 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.

Features

• Exceptional sound quality from the all new TwinPlex dual-diaphragm element
• Robust low frequency response with flat top end
• Best in class specifications and dynamic range
• Consistent off axis response results in increased gain before feedback
• Durability beyond the competition
  • Exclusive, double helix cable technology with redundant grounding
  • Nanocoated frequency caps for reduced sweat out Comprehensive accessories and microphone offerings
• Over 60 color, sensitivity, frequency response, and connector options available
  • All new clips, mounts, and accessories designed on extended research and field testing
• High RF immunity for use with today’s digital wireless systems.
• Paintable cables allow for discreet placement in professional theater applications.
• Interchangeable frequency response caps offer adjustable flat or presence responses (TL45, TL46, TL47).

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 4­pin 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 3­wire/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.
