Introduction

This tutorial provides a comprehensive guide to understanding routing in live event sound engineering and concert mixing. Routing, also known as signal flow or signal path, is crucial for ensuring audio signals are correctly directed from the sound source to the PA system. This guide will help you grasp the basic concepts of routing and signal flow, which are essential for any audio engineer working with live performances.

Step 1: Understand Routing Basics

• Routing refers to the direction of the audio signal from a source to the console and then to the output system.
• Familiarize yourself with the terms:
  • Signal Flow: The path that an audio signal takes from the source to the output.
  • Physical Inputs and Outputs: The actual connections on the console where audio signals are plugged in and sent out.
• Learn that routing is critical to determine where the sound originates and where it eventually goes.

Step 2: Identify Console Channels

• Each audio source will correspond to a specific channel on the mixing console.
• Ensure you know how to:
  • Name and label each channel appropriately for easy identification.
  • Adjust the channel settings (gain, EQ, effects) before routing the sound to the master fader.

Step 3: Route Channels to the Master Fader

• Channels must be routed to the master fader for overall control of the audio mix.
• Steps to route:
  1. Select the channel you want to route.
  2. Use the routing buttons (often labeled as “Route To”) on the console to assign the channel to the master output.
  3. Verify that the signal is reaching the master fader by checking the level meters.

Step 4: Configure Physical Outputs

• After routing to the master fader, configure the physical outputs.
• Steps to configure:
  1. Identify the physical output connections on your console.
  2. Connect these outputs to the appropriate equipment (e.g., PA system, stage monitors).
  3. Check for signal presence at the outputs to ensure everything is set up correctly.

Step 5: Troubleshoot Routing Issues

• If sound is not coming through, it may be due to incorrect routing.
• Common troubleshooting tips:
  • Check if the channels are properly routed to the master fader.
  • Ensure physical outputs are connected and powered on.
  • Verify that all necessary channels are unmuted and their levels are appropriately set.

Conclusion

Understanding routing and signal flow is essential for successful live event sound engineering. By following these steps, you can ensure that audio signals are properly directed from the stage to the audience. Familiarize yourself with your mixing console, practice routing channels, and troubleshoot effectively to enhance your live sound engineering skills. As you gain more experience, consider exploring advanced routing techniques and tools for more complex sound setups.
