MICROPHONE FEEDBACK:
“Feedback” is a howling or screeching sound that occurs when the microphone(s) comes too close to the
speaker. To avoid microphone feedback, keep the microphone(s) as far away from the speaker as the
microphone cable(s) will allow. If you must bring the microphone(s) close to the speaker, such as when
you are changing a disc or adjusting one of the other controls on the front of the unit, set the
microphone(s) ON/OFF switch(es) to the OFF position.
