The white Shure WL183m is a discreet, low-profile omnidirectional lavalier microphone well suited to a wide variety of interview, presentation, broadcast, and film/video applications. The mic features a 3-pin LEMO connector compatible with select Shure wireless transmitters. Not only does the lav offer a profile that is 8mm shorter than previous models, but the WL183m delivers better audio quality with an improved presence response, higher dynamic range, and lower self-noise for crystal clear speech and vocals.

The electret condenser capsule filters out unwanted low frequencies below 70 Hz and delivers a high-end response up to 20 kHz to provide clear, intelligible speech for instructors, journalists, and presenters doing interviews, voiceovers, and dialog. The diaphragm can handle SPL levels up to 133.5 dB, while the forgiving omnidirectional polar pattern picks up sound evenly in a 360° radius, helping to provide consistent levels, even when the talent turns away from the mic.

Optimized for a 5 VDC plug-in power source, the mic features a 4' cable terminating in a 3-pin LEMO connector for use with a compatible Shure wireless bodypack transmitter or similar device. A snap-fit windscreen and adjustable lapel clip that offers 90° rotation for optimal mic placement are included. A zippered storage pouch is also supplied.

LEMO 3-Pin ConnectorCompatible Wireless Transmitters

• Shure: works with Shure transmitters equipped with a LEMO 3-pin connector, including the following models: AD1, ADX1, ADX1M, and ULXD1 
• Third-party devices: the WL183m will work with third-party wireless transmitters that are equipped to supply 5 VDC through a LEMO 3-pin connector.

A Discreet and Dependable Omnidirectional Lavalier

Omnidirectional Polar Pattern

The mic's omnidirectional polar pattern picks up sound from all around the capsule, helping to supply consistent speech levels, even when the talent isn't speaking directly toward the microphone.

Headroom for Speech and Vocals

This LEMO version of the WL183m offers a 111.5 dB dynamic range and a very low self-noise of only 22 dB SPL; it can also handle up to 133.5 dB SPL with only 1% total harmonic distortion (THD), providing headroom for broadcast-quality interviews, speech, and dialog.

Frequency Response Tailored for Speech

With a frequency range from 70 Hz to 20 kHz, the mic filters out unnecessary low frequencies and provides an extended high-end range for accurate and transparent speech reproduction.

Low-Profile Appearance

Compared to the original, the durable aluminum alloy housing on the WL183m is 8mm shorter and features a smaller snap-on windscreen, providing a more discreet appearance for presenters, performers, and on-camera talent.
