Introducing the Lectrosonics WM-20: Mastering Harsh Environments with Advanced Wireless Technology
The Lectrosonics WM-20 Watertight Wireless Microphone Transmitter is engineered to perform flawlessly in the most demanding conditions, whether wet or dusty. Designed for durability and exceptional audio fidelity, the WM-20 is an ideal choice for professionals in film, television, and live stage performances. Its robust build and comprehensive feature set make it a reliable companion for capturing high-quality sound in any environment.

Premium Audio Quality in Any Setting
At the heart of the WM-20 lies a superior input preamp, constructed from high-quality, low-noise components. This preamp offers a broad gain range, ensuring that your audio is clear and rich, regardless of the surrounding noise. The onboard DSP-controlled limiter, with its extensive 30 dB range and dual-release envelope, works to keep the sound transparent yet free from distortion, even when operating at high volumes. Additionally, the dual-color LEDs on the control panel provide precise visual cues for audio input levels, allowing for meticulous gain adjustments on the fly.

Revolutionary Digital Hybrid Technology
Lectrosonics’ patented Digital Hybrid technology sets the WM-20 apart by combining the best of digital and analog approaches. This technology encodes the digital audio signal for analog transmission, maintaining the purity of the sound through the air, then seamlessly converts it back to digital at the receiver. The result is a dramatically reduced noise floor and crystal-clear audio reception over extended distances, making the WM-20 a powerhouse for broadcast quality sound.

Robust Build for Extreme Conditions
The WM-20 is constructed from solid, machined aluminum, providing a sturdy, corrosion-resistant housing that can withstand severe conditions. The moisture-sealed control panel features a backlit LCD and enlarged membrane switches that are easy to operate, even in challenging environments. The transmitter’s antenna, crafted from a durable multistrand alloy, is designed for heavy use and is protected by a compression-sealed strain relief to prevent the ingress of dust and moisture.

Optimal Performance with Versatile Power Options
To accommodate various application needs, the WM-20 offers selectable output powers of 50, 100, or 250 mW. This flexibility allows users to choose the appropriate power setting based on the specific requirements of the operating environment, balancing performance with battery life. The transmitter is powered by two lithium AA batteries, providing up to 14.5 hours of continuous operation, ensuring reliability throughout extended shooting or performance schedules.
