2. GENERAL DESCRIPTION
The TOA's WM-5270 Wireless Microphone employs a dynamic microphone with high input handling capacity,
and is suitable for vocal use.
3. FEATURES
• One frequency can be selected from 64 frequencies (16 channels x 4 banks) of 636 – 698 MHz.
• An optimized PLL-synthesizer minimizes the oscillation frequency drift resulting from the ambient
temperature or voltage fluctuation.
• The maximum input sound pressure can be set in the range of 130 dB SPL to 142 dB SPL by a PAD switch,
permitting adaptation to wide range of input sound pressure.
• Power/Battery lamps indicate battery consumption to prevent the unit from malfunctioning when the battery
level remarkably decreases.
• Operates on a single AA battery.
• Employs a built-in antenna.
• The state of battery consumption can be displayed on the tuner's indicator when the unit is used in
conjunction with the optional WT-5800, WT-5805 or WT-5810 Wireless Tuner.
