Now that wearing a mask is the new normal, being clearly heard is a constant struggle. Amp-Up™ makes it easy to be heard without straining your voice. With its lightweight design, long battery life and clear, crisp amplification, the Amp-Up™ Amplifier is a winner and a must-have for teachers, coaches, receptionists, retail associates, pharmacists and others!

When you’re speaking to a small group, school audience or at an outdoor event, you need to be clearly heard, and Amp-Up™ packs a lot of punch with quality sound and easy-to-use controls. Amp-Up™ has top-mounted button/dial controls, making it easy to adjust the sound volume, change to different modes and turn the unit on and off.

Amp-Up™ now has a 40 multi-channel feature, allowing up to 40 different PA-25W devices can be paired and operated simultaneously near each other without creating any channel conflicts between wireless head-worn microphone and its main amplification unit.
