WL50 Subminiature Lavalier

Shure's 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. 

  • 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 

 

 

Subminiature lavalier mic provides low visibility with professional audio quality. Less susceptible to wind noise, pop, movement.
  • 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
