11.Perform a sound check on all of the microphones that will be active. Get them as close to the performance level as possible without feedback. You should get a reading that is close to “0” dBu on the input meters of the AFS224 when

performing this sound check. When done ask all performers to be very quiet (and

possibly plug their ears) or walk off the stage (and plug their ears).
