Shure - Wireless Systems - WL50 Professional Subminiature Lavalier Microphones

WL50 Professional Subminiature Lavalier Microphones

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, as well as with the Shure ULX, 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

Wireless 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
One termination: 4-pin mini connector (fits directly into Shure wireless transmitters)
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
