Why is the volume so low (not loud enough)?
We recommend connecting the mic to the speaker with a 1/4'' input that is designed for a mic connection. If your speaker has only a 3.5mm line or aux in, which requires a signal that has a higher level of power than a mic signal does. Mismatch will result in low sound.
This is a unidirectional dynamic mic, which's being said less sensitivity to noise as well as sound source than a dynamic mic. So, please hold the mic and keep it close to the user's mouth for a loud and clear sound.
Turning up the mic volume on the speaker and using the mic at least 9 feet away from the speaker.
How Can I Avoid Feedback Noise?
Before the setup, turn down the volume control and treble of the speaker. When plugging the receiver in, do not point the mic at the speaker.
During use, pay attention to these parts:
Slowly adjust the volume setting of the speaker.
Hold the mic close to the user's mouth for a loud and clear sound.
Keep the mic at least 9 feet away from the speaker for perfect effect.
Try to use the mic with another speaker if possible.
