Microphone Basics Avoiding Feedback Acoustic feedback can be a problem in any sound system. Audio systems that include wireless microphones are somewhat more prone to feedback than those using only wired microphones, simply because the freedom of movement with wireless makes it more likely that the user will walk in front of the speakers. Take steps to make it less likely that the wireless user will walk in front of the speakers. These steps can include more rehearsal time, markings on the

Understanding and Avoiding VHF Interference Recognizing Interference The ways of recognizing the type of interference present are observing the receiver LED indications and carefully listening to the audio. A set of headphones can be a useful tool in isolating and analyzing interference problems. With headphones it is easier to listen to one wireless channel at a time, even when the system is in use. Below are some interference descriptions. Most likely there is one that matches the symptoms

Understanding and Avoiding VHF Interference Avoiding Basic Problems Sometimes interference problems have very basic causes. To avoid wasting time on an easily correctable problem, check the following items before proceeding: • Make certain than no radio transmitters are allowed to come closer than approximately 10 to 15 feet of the wireless receiver antennas. This can overload the receiver and increase the chances of interference. • Make certain not to allow receiver antennas to touch each

This problem is more common than might be expected, especially
