Lectrosonics WM-21 Watertight Wireless Microphone Transmitter with M152/WP Lavalier Mic (Freq Block 21)

Lectrosonics WM-21: Optimal Performance in Demanding Environments
The Lectrosonics WM-21 Watertight Wireless Microphone Transmitter is specifically engineered to excel in environments where moisture and dust are prevalent. This rugged transmitter is ideal for use in field productions, live performances, and broadcasting scenarios—anywhere that demands high-quality audio transmission in potentially harsh conditions. With its comprehensive features, the WM-21 is equally effective on stage, in film, and on television sets.

Exceptional Audio Clarity and Control
Built with high-quality, low-noise components, the WM-21's input preamp offers a wide gain range, ensuring clear sound capture across various environments. A sophisticated DSP-controlled input limiter provides more than 30 dB of dynamic range with a dual-release envelope, maintaining transparency and minimizing distortion even under challenging audio inputs. The control panel's dual-color LEDs offer precise feedback for audio level adjustment, making it easy to optimize settings on the fly.

Advanced Digital Hybrid Wireless Technology
Lectrosonics' patented Digital Hybrid technology is at the core of the WM-21, blending digital audio with analog transmission methods to achieve a low noise floor and pristine audio clarity over extended ranges. This innovative approach ensures superior sound quality and reliability, crucial for professional audio applications where distance and environmental obstacles can compromise other systems.

Durable and Secure Construction
The WM-21 is housed in a solid, machined aluminum casing with a corrosion-resistant finish, designed to withstand rigorous use. Its moisture-sealed control panel, featuring a backlit LCD and enlarged membrane switches, ensures durability and ease of use in wet or dusty conditions. The robust antenna, made from a durable multistrand alloy, is equipped with a compression-sealed strain relief to protect against environmental ingress.

Efficient Power Management and Versatile Operation
Offering selectable output power of 50, 100, or 250 mW, the WM-21 allows users to tailor transmission strength based on specific situational needs, optimizing both operational range and battery life. Powered by two lithium AA batteries, it supports up to 14.5 hours of continuous use, providing reliable performance throughout extended shoots or events.
