With nothing 
plugged into the

reversed or open (hot, neutral, and/or ground) contacts.

•  If using an extension cord, plug the S1 Pro directly into the outlet.

adjusted, "input pads" are available from your preferred instrument retailer.

encountering 
feedback

•  Orient the microphone so that it is not pointing directly at the loudspeaker.

•  Try a different microphone.

•  Try a different position for the loudspeaker and/or vocalist on stage.

•  Increase the distance from the loudspeaker to the microphone.

•  If using a vocal effects processor, make sure it is not contributing to the 

feedback problem.

functionality.
