About the Shure WL50B Omnidirectional Condenser Lavalier Microphone

The Shure WL50B is a professional omnidirectional condenser lavalier microphone designed for clear and reliable speech capture in broadcast, presentation, and performance applications. This microphone utilizes a miniature electret condenser capsule known for its smooth frequency response and natural vocal reproduction. Its omnidirectional polar pattern provides consistent 360-degree pickup, ensuring stable audio levels and a natural sound even when the wearer turns their head, which is advantageous for dynamic presenters or performers. The microphone is terminated with a specific connector designed for direct compatibility with Shure wireless bodypack transmitters, ensuring a secure and reliable connection that prevents accidental disconnection during movement.

The microphone's small size and low-profile design allow for easy concealment under clothing, on ties, or with specialized clips, making it a preferred choice for television anchors, theater actors, and corporate speakers where maintaining a clean visual appearance is essential. It requires plug-in-power, which is supplied by the connected Shure wireless transmitter, powering its internal preamplifier for a strong, low-noise signal. The included comprehensive accessory kit typically contains various mounting options such as clips, adhesive pads, and a windscreen, providing solutions for secure and discreet placement on a wide range of clothing types. The durable cable is designed to minimize handling noise.

For sound engineers and production professionals, the Shure WL50B paired with a compatible wireless system provides a dependable and high-performance lavalier solution. Its combination of small size, consistent omnidirectional pickup, and secure connector makes it a standard tool in many professional audio kits. It delivers the clear, intelligible dialogue necessary for broadcast, live events, and recorded media, ensuring the wearer's voice is captured with clarity and consistency without visual distraction.

FAQs about Shure WL50B Omnidirectional Condenser Lavalier Microphone

What is the primary function of the Shure WL50B lavalier microphone?

The WL50B is an subminiature electret condenser lavalier microphone designed for theater, television broadcasting, film production, and high-profile public speaking. Its ultra-small footprint allows it to be easily hidden in clothing, hair, or costumes while delivering natural, full-range voice reproduction.

What polar pattern does the WL50B feature?

It features an omnidirectional polar pattern that captures audio evenly in a 360-degree radius around the capsule. This uniform pickup helps maintain smooth, consistent audio levels even if the performer turns their head or if the microphone shifts position during movement.

What connector type is installed on this microphone model?

The "B" version (black finish) comes terminated with a standard 4-pin mini-connector (TA4F / TQG). This enables direct plug-and-play connection to all compatible Shure wireless bodypack transmitters, as well as third-party bodypacks using TA4M inputs.

Does the WL50B include equalization caps to tailor frequency response?

Yes, it includes interchangeable acoustic response caps that let you adjust the high-frequency response of the microphone. You can attach the boost cap for added clarity and presence when mounted on clothing, or use the flat cap for transparent, uncolored audio.

Does the microphone require phantom power or bias voltage to operate?

Yes, as a condenser microphone, it requires a small DC bias voltage (5V DC) supplied directly by a connected wireless bodypack transmitter. If you need to plug it into a standard XLR mixer input with 48V phantom power, an optional Shure RK100PK inline preamp adapter is required.

What accessories come included with the WL50B?

The package includes a tie clip, a dual tie clip, a magnet mount assembly for versatile mounting options, acoustic equalization caps, foam windscreens to minimize plosive noise, and a protective storage case.

How durable is the cable on the WL50B?

The microphone features a thin, 5-foot (1.5-meter) Kevlar-reinforced cable designed to resist kinking and snapping during demanding stage or broadcast use. The durable cable construction also minimizes mechanical cable handling noise when concealed under clothing layers.

What is the difference between the WL50B and other WL series lavaliers like the WL183?

The WL50B is significantly smaller than the WL183/WL185 series, making it a subminiature microphone designed specifically for low-profile, concealed placement in theater and film. It also features interchangeable acoustic equalization caps rather than interchangeable polar pattern capsules.
