Did you know?

This voice amplifier is designed with an inbuilt noise and feedback interference reduction function. Always avoid positioning your microphone near the speaker unit when switched on, as this can cause the unwanted feedback.

Microphone squeal is caused by feedback. Feedback happens when your microphone picks up the output sound from the voice amplifier speaker, which it then re-amplifies causing a loop which is caused by the microphone picking up the original amplified sound and amplifying it again and again…until the sound can’t be amplified anymore and something has to give.

Usually your listener’s ears!
