The Bietrun 20W Wireless Voice Amplifier for Teachers is designed to cover up to 10,000 sq.ft (1,000 ㎡) with its powerful, clear, and distortion-free sound. This rechargeable personal voice amplifier features a 2,000mAh lithium battery that can operate for up to 12 hours at maximum volume, and it takes only 3 hours to fully charge. The wireless microphone can be used for approximately 6 hours, and a 2-in-1 charging cable is included to charge both the amplifier and the wireless mic simultaneously.

The voice amplifier is portable, lightweight (0.45 lb/204g), and compact, making it suitable for various settings, from indoor to outdoor use. It can be clipped to your belt or pocket, or worn around the waist with the included waistband belt, making it a valuable tool for teachers, coaches, presenters, tour guides, and classrooms with up to 50+ members.

The Bietrun voice amplifier offers multiple functions, including Bluetooth 5.0 (30M) connectivity, TF (Micro SD) card and USB Disk support, FM radio, recording (in wired mic mode), and 3.5mm AUX audio input. You can long-press the Play/Pause button to repeat a single tune or loop all music. Ensure that a TF card or USB Disk (not included) is inserted before recording.

The voice amplifier comes with both wired and wireless microphone options. The wired microphone can be plugged into the MIC jack, and the wireless mic will pair automatically within 3 seconds. The wireless mic has 60 channels, and you can short-press the Pair button to avoid interference. Both microphone headsets are lightweight and adjustable, allowing you to find the optimal distance between the microphone and your mouth.

To ensure a seamless user experience, it is important to note that the microphone should not be placed in front of the voice amplifier, as this may cause noise or static. The Bietrun voice amplifier's UHF transmission and 20W peak power provide powerful, clear, and distortion-free sound, making it a reliable and versatile solution for various applications.
