Feedback
Feedback is a high-pitched noise caused when the sound through a speaker is picked
up again by the microphone. If there is feedback in the system, it can be removed/
reduced with the tips below:
• Practice proper microphone placement. The mic should be as close as possible
to the mouth. Use a headset whenever possible; lapel mics are more prone to
feedback.
• Practice proper setup of the gain structure throughout the system. Start from the
source (wireless mic system) and ensure all levels are good.
• Make sure to use the windscreens on the microphones.
• Try a different mic. Cardioid mics will have a higher gain before feedback than
omnidirectional mics. However, Cardioid mics will have more wind noise versus
omnidirectional. When it comes to choosing between wind noise or feedback, it’s the
lesser of two evils to listen to wind noise.
• Be aware of areas prone to feedback, such as from the 20 yard line and in.
Communicate to the referee that they shouldn’t be making announced calls past a
certain point on the field.
For additional recommendations for reducing wireless microphone dropouts and
feedback, refer to the Wireless Mic Best Practices (DD3871886) , available online at
