A single glance at the Shure WL184M Black will be enough to tell wireless‑system specialists that they're looking at a real innovation. This lavalier microphone is remarkably compact, yet delivers exceptionally high performance levels. Its supercardioid condenser capsule, designed for targeted capture and strong isolation, connects via a TA4F plug to compatible Shure TA4 bodypacks. Suitable for any of the vast range of speech‑reinforcement applications, this clip‑on microphone gives voices excellent presence, with its extended frequency range making it easy to achieve a brilliant sound. The Shure WL184M here is part of the WL18XM series, which is available in black and white, and includes mics with a variety of polar patterns as well devices with both LEMO and TA4F connectors. In everyday use, users will also appreciate the mic's flexible rotating clip.
The Shure WL184M can handle a maximum sound‑pressure level of 144dB. Its condenser capsule, for which the manufacturer recommends a bias voltage of 5V DC, measures only 13.55mm in length, with a diameter of 12.74mm. The lavalier's dynamic range spans 121dB, nicely complementing a self‑noise rating of only 23dB SPL. To reproduce voices faithfully, it's capable of a frequency response from 70Hz to 20kHz. Attached to the mic's lightweight aluminium‑alloy housing is a 1.23m cable with a diameter of 2.2mm, ending in a four‑pin TA4F connector for compatible bodypack transmitters (sold separately). This compact lavalier microphone weighs only 20g, and its clip can be rotated in 90° steps for optimal placement.
Professional users who choose a Shure WL184M will get a high‑performance lavalier microphone that will meet even the most exacting demands. For vocal reinforcement of the highest quality, the mic's TA4F plug need simply be hooked up to any compatible bodypack and used in combination with the series' receivers. Anyone involved in live events – from the organisers and engineers to the artists and the audience – will appreciate the WL184M's sound‑pressure capability and dynamic range, combined with low self‑noise. The mic with the 184 designation has a focused supercardioid polar pattern, making it ideal for settings where background noise could otherwise be an issue: Of course, the downside of a supercardioid is that it's more sensitive to placement and user movement.
The American company Shure began developing microphones during the early 1930s and is one of the pioneers of the audio engineering sector. Models such as the 55 Unidyne – known to many as the "Elvis microphone" – and the SM57 and SM58 which appeared in the mid-1960s are still ubiquitous in live sound production today. They enjoy cult status among musicians and technicians alike. In the 1990s, Shure introduced the first wireless microphones and in-ear monitoring systems and became a market leader in this field. In addition to microphones, Shure offers a wide range of earphones and headphones for studio and live use, as well as various accessories.
For moderators, presenters, singers, and anyone else who works with their voice, the Shure WL184M will score points with its very present sound. The mic's supercardioid pickup pattern captures the speaker's voice very precisely, reducing crosstalk between multiple mics. For best results, a supercardioid lav should be attached quite close to the sound source: If it's to be used for traditional presentations and conferences, the clip can be attached to a collar or similar. For more relaxed roundtables, comedy events, and musicals, it should be possible to find an ideal spot on a shirt, sweater, or costume, with the mic angled carefully upwards. And for open‑air events, simply attach the windscreen that this practical, powerful mic also ships with.
