Lectrosonics WM/VT500WATER-21 Water-tight Transmitter w/ VT500WATER Lavelier Mic Upgrade, BLK 21

Designed for wet or dusty environments, the WM transmitter features O-ring sealed battery compartments and input jack, a compression sealed antenna port and gasket sealed control panel and back cover. Dual AA batteries provide twice the operating time of earlier watertight transmitter designs. Larger membrane switches and control panel and a highly visible, backlit LCD enhance the user interface.

Features:
– Selectable output power to maximize battery life or and for excellent operating range (50, 100 or 250 mW)
– Machined aluminum, corrosion resistant housing
– Water resistant seals for use in wet environments
– LCD interface with lockout option
– Programmable compatibility modes for use with a wide variety of different receivers
– Servo Bias input circuitry with selectable voltage

To meet the demand for both extended operating range and extended battery life, the transmitter offers selectable output power of 50, 100 and 250 mW. With higher power output, the operating range is improved at the expense of battery life. When range is not an issue, the power can be reduced to extend the battery life. The transmitter can be controlled by the LectroRM app for hands free setup and adjustment using audible tones delivered into the microphone from your phone. The transmitter can be put to sleep to conserve battery power during setup when it is buried deep inside costuming, then awakened for normal operation when the production begins. Other adjustments include frequency, audio level and control panel lockout. The DSP-based design works with all Digital Hybrid receivers, and is backward compatible for use with Lectrosonics Mode 3 and IFB.

The input section features servo bias circuitry with voltages being selectable from the LCD to match the requirements of a wide variety of lavaliere microphones. The bias can also be turned off for use with dynamic microphones. A line level setting is provided for use with signal levels up to 5 volts. The low frequency roll-off can be adjusted from 35 to 150 Hz.

A DSP-controlled analog audio limiter is employed ahead of the first mic preamp to protect the entire audio chain from overload. The limiter has a range of more than 30 dB for excellent overload protection and a dual release envelope that makes the limiter acoustically transparent while maintaining low distortion.
