WL50 Professional Subminiature Lavalier Microphones

Shure's new WL50 lavalier microphone series sets a new standard for miniature microphones. Visually unobtrusive, the WL50s are ideal for theater, television broadcast, video/film, and event production. Designed for applications that require minimal visibility without compromising sound quality, these microphones are available individually, as well as with the Shure UHF and UC Wireless Systems. 

  • WL50B : Black, standard sensitivity, 5-ft attached cable with TA4F connector 
  • WL50BX : Black, standard sensitivity, 10-ft attached cable with tinned ends
  • WL50T : Tan, standard sensitivity, 5-ft attached cable with TA4F connector 
  • WL50T-LO : Tan, reduced sensitivity, 5-ft attached cable with TA4F connector 
  • WL50W : White, standard sensitivity, 5-ft attached cable with TA4F connector 

Features

  • All models include foam windscreens, swiveling lapel clip, dual tie clip, magnet mount, and mini mount
  • Subminiature size (5.8 mm diameter x 11 mm height)
  • Electret condenser cartridge
  • Omnidirectional pattern
  • Two termination options: 4-pin mini connector (fits directly into Shure wireless transmitters), or unterminated (bare wire)
  • Two sensitivities available:
  • Standard: -40 dBV/Pa (for speech applications)
  • Reduced: -50 dBV/Pa (10 dB more headroom for theater applications)
  • Interchangeable equalization caps for optimal clarity and response:
  • Silver mesh cap provides a 4 dB boost in the 8-18 kHz range - typically used in applications that require a microphone to be head-mounted
  • Gold mesh cap provides a 10 dB boost centered at 12 kHz - typically used in applications that require a chest-worn microphone
  • Black, beige, and white models are available
  • All models include magnet mount, lapel clip, dual tie clip, pin mount, and two foam windscreens
  • Frequency response: 20-20,000 Hz

SHURE MICROPHONES - Miniature

Intended for use wired with a cable, or with a radiomic transmitter, this selection of Shure lavalier microphones includes dynamic and electret condenser types from the popular MicroFlex series, TwinPlex series, and DuraPlex subminiature series.

SM Series

MX Series

WL Series


WL183M, WL184M, WL185M

Shure describe these condenser lavalier microphones as 'professional, low-profile' mics, and they have been designed to improve on the ever-popular WL18x series. The main difference is that the microphones are 8mm shorter than their predecessors, however they also have a higher dynamic range with improved maximum SPL.

WL183M is omnidirectional, has a dynamic range of 121dB/111.5dB (TA4F/LEMO), and a maximum SPL of 141dB/133.5dB (TA4F/LEMO).
WL184M is supercardioid, has a dynamic range of 121dB/114dB (TA4F/LEMO), and a maximum SPL of 144dB/138dB (TA4F/LEMO).
WL185M is cardioid, has a dynamic range of 120.5dB/114.5dB (TA4F/LEMO), and a maximum SPL of 140.5dB/134dB (TA4F/LEMO).

All models have a frequency response of 70Hz - 20kHz, have capsules measuring 13.55 x 12.74mm (length x diameter), and have a weight of 20g.

Included accessories: Single tie clip, snap-fit windscreen, storage bag.


WL183, WL184, WL185

Discontinued

WL183, WL184 and WL185 are electret condenser designs; each has a 1.2m cable terminated with a miniature 4-pin connector. The included tie clip mount can be rotated in 90 degree intervals for placement flexibility. The condenser cartridges are interchangeable.

Optional accessories: RB183B, RB183W, RB184B, RB184W, RB185B. RB185W alternative cartridges; C122 replacement cable and housing.


WL93, WL93-6, WL93T, WL93-6T

Model WL93 Microphones are economical, omnidirectional, sub-miniature, condenser microphones designed for general speech applications where a visually unobtrusive microphone is desirable. All are supplied with a mounting block with attached tie bar, a sew-on mounting bracket, and an acoustic windscreen to minimize wind noise in outdoor applications. They have cable terminated with a 4-pin miniature connector which connects directly to a Shure wireless body-pack transmitter. Cable lengths are 1.2m (WL93 and WL-93T) and 1.9m (WL93-6 and WL93-6T).
