How do I connect a microphone or guitar to the PartyBox 100?

First, rotate the MIC/GUITAR volume knob counterclockwise to turn the volume down, then connect your microphone or guitar to the MIC/GUITAR jack. You can adjust the microphone or guitar volume using the MIC/GUITAR volume knob, and use the volume buttons to adjust the audio source volume. When not using the microphone or guitar, decrease the MIC/GUITAR volume to minimum and remove them from the jack. (Page 6)
