WL40V

40kHz wireless vocal microphone capsule

Where to Buy

Engineered to deliver studio quality performance to the wireless world, the hand-tuned WL40V features fast impulse response, wide frequency response and high SPL handling. It excels at distance capture, making it ideal for broadcast, corporate, and live performance applications.

Its near-perfect hypercardioid polar response and 30Hz-40kHz extended flat frequency response translate to a natural on and off-axis performance coupled with benchmark levels of sonic clarity and presence. The capsule’s ultra-fast impulse response delivers a highly accurate reproduction of the nuanced details of vocals.

Interchangeable with any screw-on-type handheld transmitters that receive a 31.3mm/pitch 1.0mm threading, the electret-based WL40V works with transmitters from Lectrosonics®, Line 6®, Shure® and Sony®. Its circuitry has been specifically hardened for use with 2.4GHz wireless systems, which frequently exhibit noise with electret-based capsules, making it an ideal replacement capsule for those systems.

Rick Camp Brings Earthworks WL40V Capsule on the Road with Jennifer Lopez

“When she walks down the 50 foot ramp, when she faces the audience, her body blocks the speakers and when she turns around toward the stage, with the rear of the mic facing the speakers, it all works flawlessly. No matter which way she turns, I have no feedback problems when using the WL40V mic capsule. This capsule improved the performance by fifty percent, just by the rejection of all the outside elements such as side fills or wedges.” – Rick Camp, Jennifer Lopez FOH Engineer

Foreigner Tours with Earthworks WL40V Wireless Capsule

“In most stage situations, you get cymbal bleed like crazy, especially when you have a drummer who plays fairly hard. Even though the vocal mics were about 18 feet away from the drums, cymbal leakage was a problem. As soon as we switched to the Earthworks SR40V and WL40V the cymbal leakage almost went away. The rear rejection capabilities of the Earthworks microphones, in addition to their excellent vocal quality and the rich sound, just floored me.” – Lorenzo Banda, Foreigner Monitor Engineer

Garbage Touring with Earthworks WL40V Wireless Capsule

“Shirley is a very dynamic singer and the WL40V responds well to her different vocal styles. One song she’ll be very intense and aggressive and the next song very soft and lush. She loves the way this microphone sounds both in her ears and on the live recordings that I’ve done on the road.” – Brad Divens, Garbage FOH Engineer
