Eight gena sound principals
- Place sound control in the auditorium
- Each night’s show will be unique
- Professional sound and acoustics experts should equalize the sound system
- Sound levels for microphones, monitors, and accessories must be determined before a performance
- Sound needs may vary for the same auditorium at different times of a year
- Microphone should precede the user
- Caution speakers about swallowing the mic.
- Use duct tape to secure all cables in traffic areas.
