Setting Up a PA System for a Live Performance

Setting Up a PA System for a Live Performance

Learning Objective

At the end of the lesson, you will be able to explain how to set up a PA system for a live performance.

This slide should be used to introduce the learning objective of the lesson.

What is a PA System?

A PA (public address) system is a collection of audio equipment used to amplify sound for a large audience.

This slide should be used to introduce the concept of a PA system.

Equipment Needed

To set up a PA system, you will need a mixing console, speakers, amplifiers, and microphones.

This slide should be used to introduce the equipment needed to set up a PA system.

Setting Up the Mixing Console

Connect the mixing console to the amplifiers and plug in the microphones and other instruments. 

The mixing console will be used to adjust the levels of the different instruments and add EP, Compression, Reverb & Delay.

This slide should be used to explain how to set up the mixing console.

Setting Up the Amplifiers

Connect the amplifiers to the speakers and adjust the volume levels. 

Whereas speakers convert audio signals into sound waves, amplifiers are needed to boost the volume of the sound waves so that they are sufficient enough for the speakers to pick up. 

This slide should be used to explain how to set up the amplifiers.

Setting Up the Speakers

Place the speakers in the appropriate locations for the venue and connect them to the amplifiers. The speakers will then project the sound to ensure that the audience can hear them.

This slide should be used to explain how to set up the speakers.

Microphone Placement

Place the microphones in front of the performers and adjust the levels on the mixing console. Adjusting the gain levels on the microphone is essential in creating a good quality performance. 

If vocals are too low, the audience will not be able to hear them. If vocals are too high you could run the risk of causing hearing damage. 

This slide should be used to explain how to place the microphones for optimal sound quality.

Sound Check

Test the sound levels and make adjustments as necessary.

This slide should be used to explain the importance of sound checks and how to conduct one.

Troubleshooting

Be prepared for any technical difficulties that may arise and have backup equipment on hand. If the worst case scenario happens and technical equipment is broken during a performance with no available replacement, attendees will be disappointed and are likely to spread the word about their disappointment, which could damage your brand as an event or artist.

This slide should be used to explain the importance of being prepared for technical difficulties.

Safety Precautions

Be aware of the potential hazards of electrical equipment and take necessary safety precautions. Potential hazards:

- Trailing wires - Are there any trip hazards?

- Loudness - Have volume levels been controlled?

- Capacity - Is there enough space in the performance area?

- Electricity - Are there any electrical hazards?

This slide should be used to explain the importance of safety precautions when setting up a PA system.

Recap

1. What is the difference between a speaker and an amplifier?

2. Why is volume control and balance essential for a live performance?

3. What are the four pieces of equipment that make up a PA system?

This slide should be used to introduce an assessment to test student understanding.

Practice Exercise 

In groups of 2, you will now go into the venue and set up the PA system. 

This slide should be used to explain the details of the group exercise.
