Setup
- Charge the Amplifier: Before first use, fully charge the voice amplifier. Connect the small end of the USB charging cable to the DC 5V port on the amplifier and the larger end to the wall adapter. Plug the wall adapter into a power outlet. The charging indicator light will illuminate.
- Connect the Headset Microphone: Insert the 3.5mm jack of the wired headset microphone into either of the two MIC ports (MIC1 or MIC2) on the side of the amplifier unit.
- Position the Microphone: Place the headset comfortably on your head. Position the microphone boom so that the microphone is approximately 1-2 inches from your mouth for optimal sound pickup.
- Power On: Locate the ON/OFF switch on the side of the amplifier. Slide it to the "ON" position.
- Adjust Volume: Use the volume control knob to set the desired amplification level. Start with a lower volume and gradually increase it to avoid feedback.

Operating Instructions
Once the amplifier is set up and powered on, you can begin using it to project your voice.
- Speaking Clearly: Speak naturally into the headset microphone. Ensure the microphone remains close to your mouth for the best sound quality and to minimize background noise.
- Volume Adjustment: Adjust the volume knob as needed to suit your environment and audience size. Avoid setting the volume too high, which can cause feedback (a high-pitched squealing sound).
- Multiple Microphones: The amplifier supports two microphone inputs (MIC1 and MIC2), allowing for flexibility if you have an alternative compatible microphone.
