15W UHF Wireless Portable Voice Amplifier for Teaching, Lectures & Tour Guides — U-Disk Megaphone Speaker, Long Battery Life

Compact yet powerful 15W voice amplifier designed for classrooms, tours, promotions and meetings. Delivers enough volume for up to 200 people indoors or about 100 people outdoors, and still amplifies sound while playing music or reading from a U-disk. The small form factor offers louder output than many standard loudspeakers. Wireless microphone features a built-in digital intelligent chip that automatically adjusts levels and reduces noise across different decibel conditions. The system uses UHF wireless transmission with a 50m range, so you don’t need to stay next to the amplifier while speaking. Power and playback: built-in rechargeable 2400mAh battery supports continuous voice amplification for up to 12 hrs and music playback for up to 8 hrs. Connect via AUX, play from an inserted U-disk, stream over Bluetooth, or tune FM radio. One-key recording is available (insert TF card first). Music playback supports single-track repeat and full-playlist loop modes. Practical for teaching, training, guiding tours, conferences and promotions. Includes a lanyard that can be worn on the wrist or shoulder to free your hands.
