How do you test and troubleshoot your sound system before and during a performance?

2 Set up and connect your devices

The next step is to set up and connect your devices, following the manufacturer's instructions and safety guidelines. You should place your mixer in a central and accessible location, where you can control the sound levels and cues. You should also position your speakers strategically, aiming for a balanced and even coverage of the audience area, and avoiding direct contact with walls, windows, or microphones. You should also test your microphones, whether they are wired or wireless, handheld or lavalier, and adjust their sensitivity and placement according to your actors' voices and movements. You should also check your cables, connectors, and stands for any damage or loose connections, and secure them with tape or ties.

5 Handle feedback and noise

The fifth step is to handle feedback and noise, which are two of the most common and annoying problems that can affect your sound system. Feedback is the high-pitched squeal that occurs when a microphone picks up the sound from a speaker and creates a loop. Noise is any unwanted sound that interferes with your signal, such as hum, hiss, buzz, or crackle. To prevent or reduce feedback, you should avoid placing your microphones too close to your speakers, or pointing them directly at them. You should also use directional microphones that reject sound from the sides and rear, and lower the volume or EQ of the frequencies that cause feedback. To prevent or reduce noise, you should use shielded cables that block electromagnetic interference, and plug your devices into separate power sources or surge protectors. You should also avoid coiling or crossing your cables, or placing them near fluorescent lights, computers, or other sources of noise.

6 Optimize your sound quality

The sixth step is to optimize your sound quality, and make sure your sound system enhances your production and creates the desired mood and atmosphere. You should use your mixer's features and functions to fine-tune your sound, such as EQ, compression, reverb, delay, or other effects. You should also balance your sound levels and panning, and create smooth transitions and fades between scenes and songs. You should also consider the acoustics of your venue, and how they affect the sound absorption and reflection. You should also consult with your director, designer, and actors, and get their feedback and suggestions on how to improve your sound design.
