About Lectrosonics WM/VT500WATER-25

Take your audio transmission to the next level with the WM/VT500WATER-25 Watertight Belt-Pack Transmitter, Frequency Block 25. Engineered for challenging environments, this robust transmitter is equipped with O-ring sealed battery compartments and input jack, a compression-sealed antenna port, and a gasket-sealed control panel and back cover, ensuring optimal performance in wet or dusty conditions.

The WM/VT500WATER-25 transmitter is powered by dual AA batteries, offering double the operating time of previous watertight transmitter models. User interaction is enhanced with larger membrane switches, a control panel, and a highly visible, backlit LCD. This versatile device is available with either an M152WP Lav Microphone or, for an upgraded experience, the Voice Technologies VT500 Water Lav Microphone.

This transmitter is designed with selectable output power, allowing you to balance between battery life and operating range. Choose from 50, 100, or 250 mW output power based on your specific needs. The machined aluminum housing is corrosion-resistant, ensuring durability and longevity.

The WM/VT500WATER-25 transmitter features programmable compatibility modes, making it suitable for use with a wide range of receivers. The servo bias input circuitry with selectable voltage caters to a variety of lavaliere microphones, and can also be turned off for use with dynamic microphones.

The DSP-based design ensures compatibility with all Digital Hybrid receivers and is backward compatible with Lectrosonics 200 and 100 Series and IFB receivers, as well as some other brands of analog wireless receivers. The transmitter can be controlled remotely for hands-free setup and adjustment, and it can be put to sleep to conserve battery power when not in use.

The transmitter's input connector is designed for watertight connections, and the antenna is mounted with a compressible strain relief for a watertight connection. The device also features a DSP-controlled analog audio limiter for excellent overload protection, maintaining low distortion while preserving short-term dynamic changes.

The WM/VT500WATER-25 transmitter also includes a specialized RF isolator that reduces RF intermodulation when multiple units are used in close proximity. This feature also protects the output stage from electrostatic shock delivered to the antenna.

Enhance your control over the transmitter with the LectroRM mobile application, available for iOS and Android. This app allows you to remotely change settings on the transmitter through encoded audio tones. The user-friendly interface makes it easy to select the desired setting and option, and a mechanism is in place to prevent accidental activation of the tone.

In conclusion, the WM/VT500WATER-25 Watertight Belt-Pack Transmitter, Frequency Block 25, offers a comprehensive solution for high-quality audio transmission in challenging environments. Its robust design, advanced features, and user-friendly interface make it a reliable choice for professionals in the field.
