Some wireless microphones use a 3.5mm or 1/4 inch jack on the back of the microphone, while others require an adapter if they are not equipped with a regular audio input. Find out what type of connector your microphone uses by looking it up online or contacting the manufacturer. Once you have determined how to connect the microphone, plug it in and turn on your speaker. If everything is set up correctly, you will hear sound coming from the microphone when you press any button on the speaker.
