TheWM Watertight Belt-Pack Transmitter with Lavalier MicfromLectrosonicsis designed for wet or dusty environments. It features an O-ring sealed battery compartment and input jack, a compression sealed antenna port, and a gasket sealed control panel and back cover. It can be used when paired with a wireless receiver for capturing audio in broadcast TV, ENG (Electronic Field Productions), and EFP (Electronic Field Production) applications, and more.
Dual AA batteries provide twice the operating time of earlier watertight transmitter designs and the larger membrane switches and control panel have a highly visible backlit LCD, which enhances the user interface. In addition, there are 50, 100, or 200 mW selectable-output power switches to maximize battery life and operating range.
Some other features include servo bias input circuitry with selectable voltage for compatibility with other microphones, and programmable compatibility mode for use with a wide variety of different receivers. The transmitter is enclosed in a machined-aluminum corrosion resistant housing and includes a Lectrosonics M152/WP omnidirectional lavalier mic, a belt clip, an O-Ring kit, and two AA lithium batteries.
