Using the Voice Amplifier
1.
Attach the voice amplifier to your waist using either the belt clip or the waist band.
2.
It is recommended that you wear the microphone headset as shown in the diagram.
3.
For best performance adjust the microphone tip so that the two holes inside the sponge aim at
your mouth and the tip is 1 to 1.5 inches (2-3cm) from your mouth. An easy way to tell the
correct position is to make sure the white line on the microphone tip is facing your mouth.
The microphone is directional so placement is very import for controlling feedback.
4.
Insert the plug of the microphone into the port labeled “microphone” on the voice amplifier.
5.
Turn the volume dial to turn on the voice amplifier and to adjust the volume. The LED RED
light will turn on when the voice amplifier is on.
6.
Adjust the volume level to the desired loudness. You can reduce feedback or screeching by
reducing the volume or moving the speaker further from the microphone.
Note: For the best sound performance and clarity, please use the microphone that has been
provided with this voice amplifier.
