Watertight Wireless Microphone Transmitter with M152/WP Lavalier Mic
|
The LECTROSONICS WM Watertight Wireless Microphone Transmitter by Lectrosonics is designed to operate in wet or dusty environments. The WM resists damage in harsh environments, but also offers a comprehensive feature set that makes it equally at home in film, television, and on stage.
The LECTROSONICS WM's input preamp is built of 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. Dual-color LEDs on the control panel accurately indicate audio input level for precise gain adjustment.
LECTROSONICS WM features include:
- Frequency Block 25
- Water Resistant Seals
- Digital Hybrid Wireless Technology
- Variable, Selectable Power Output
- 256 Synthesized UHF Frequencies
- Servo Bias Input with Selectable Voltage
- Corrosion-Resistant Aluminum Housing
- Compatibility Modes for Versatile Usage
- LCD Interface with Lockout Option
- Lasts Over 14hrs on Lithium AA Batteries
