VHF Wireless System
WM-4300 Wireless Microphone
- WM-4300 Wireless Microphone
- The wireless microphone WM-4300 is of lavalier type designed for use on UHF band. It accommodates the supplied electret condenser microphone unit with a cardioid pick-up pattern and is suitable for vocal and speech reinforcement applications. The built-in circuitry is so designed to minimize the influence from ambient noise.
- One frequency can be selected from 64 operating frequencies (4 banks x 16 channels) of 64 frequencies of 690 - 865 MHz.
- An optimized PLL-synthesizer minimizes the oscillation frequency drift resulting from the ambient temperature or voltage fluctuation.
- Audio level control adjusts the microphone sensitivity.
- Battery lamp indicates battery consumption to prevent the unit from malfunctioning when the battery leve remarkably decreases.
- Compact size and high reliability
- A commercial microphone unit of the type equivalent to the supplied one can also be used.
