Shure WL183M Overview
A Discreet and Dependable Omnidirectional Lavalier
The black Shure WL183m is a discreet, low-profile omnidirectional lavalier microphone well suited to a wide variety of interview, presentation, broadcast, and film/video applications. Not only does the lav offer a profile that is 8mm shorter then previous models, the WL183m delivers better audio quality with an improved presence response, higher dynamic range, and lower self-noise for crystal-clear speech and vocals.
Optimized for a 5 VDC plug-in power source, the mic features a 4' cable, terminating in a TA4F 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.
Omnidirectional Polar Pattern
The mic's forgiving omnidirectional polar pattern picks up sound evenly in a 360° radius 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
The electret condenser capsule in this TA4F version of the WL183m offers a 121 dB dynamic range and a very low self-noise of only 20 dB SPL; it can also handle up to 141 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 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.
