TOA WM-4200 ไมโครโฟนไร้สาย Wireless Microphone

• WM-4200 Wireless Microphone

• The WM-4200 Wireless Microphone employs a dynamic microphone element with high input handing capacity and is suitable for vocal applications and other professional uses.

• One frequency can be selected from 64 operating frequencies (4 banks x 16 channels) of 690 - 865 MHz.

• An optimized PLL-synthesizer minimizes the oscillation frequency drift resulting from the ambient temperature or voltage fluctuation.

• Dynamic range of over 110 dB can be obtained when the unit is used in combination with the WT-4800.

• Audio level control adjusts the microphone sensitivity.

• Power switch features a lock mechanism to protect accidental power-off.

• Battery lamp indicates battery consumption to prevent the unit from malfunctioning when the battery level remarkably decreases.
