Avoiding Acoustic Feedback
Acoustic feedback is the loud howl or squealing sound heard through sound systems as the result of sound from the

When practical, a single microphone is preferred. Additional microphones pick up more sound from the speakers and
each mic has to be turned down a little to prevent feedback. However, if you have difficulty balancing the level of
different individuals with one mic, or if you still cannot get sufficient gain, using more mics can offer an advantage.
Giving several singers their own microphones, for example, allows placement of the microphones much closer to each
singer. This increases the volume of the sound at the mic and far outweighs any detrimental effect from using multiple
mics. It also allows the volume of each mic to be adjusted separately for proper balance.
Reverb
Adding reverberation to music can enhance the sound of that music. To add reverb to a microphone, simply turn up the
REVERB control (Fig. 7) on the appropriate input channel. Add reverb in moderation because too much reverb makes
vocals hard to understand. In most cases, it is best not to add reverb to the spoken word.
