Lectrosonics WM-21, WATER-TIGHT TRANSMITTER, 2 AA, VARIABLE RF POWER, WITH MIC

The Lectrosonics WM-21 is a Watertight Wireless Microphone Transmitter by Lectrosonics which is designed to operate in wet or dusty environments. The Lectrosonics WM-21 resists damage in harsh environments, but also offers a comprehensive feature set that makes it equally at home in film, television, and on stage. Also, the Lectrosonics WM-21 input preamp is design with a very high quality, low noise components with a wide gain range. The DSP-controlled input limiter has a range of more than 30 dB and a dual-release envelope, making it transparent while maintaining low distortion. It has a dual-color LEDs on the control panel accurately indicate audio input level for precise gain adjustment.

Lectrosonics patented Digital Hybrid technology revolutionizes wireless microphone transmission. Digital audio signal is converted and encoded for analog transmission, then decoded and converted back to digital audio at the receiver. The result is an exceptionally low noise floor with clear audio reception retained at greater distances. To meet the demand for both extended operating range and extended battery life, the Lectrosonics WM-21 transmitters offer selectable output power of 50, 100 or 250 mW. The Lectrosonics WM-21 transmitter is made of solid, machined aluminum housing with a corrosion-resistant finish. The moisture-sealed control panel of the Lectrosonics WM-21 has a backlit LCD and enlarged membrane switches. The antenna is built of an extremely durable, multistrand alloy that will withstand heavy abuse. It is mounted with a compression sealed strain relief that prevents dust and moisture from entering the housing.
