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
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
- 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
