How To Run 2 Mixers At Once: A Comprehensive Guide

Running two mixers simultaneously might sound complex, but with the right approach and understanding, it's entirely achievable. This guide will walk you through various scenarios, techniques, and considerations to help you successfully operate multiple mixers at once. Whether you're a seasoned audio engineer or a beginner, this comprehensive guide will provide valuable insights.

Understanding Your Mixing Needs

Before diving into the technical aspects, it's crucial to define your objectives. Why do you need to run two mixers concurrently? Common scenarios include:

• Separate Sound Sources: You might have two distinct audio sources, such as a live band and a DJ, that require independent mixing and control.
• Submixing: One mixer could act as a submixer, handling specific instrument groups or vocal harmonies, before feeding its output into a main mixing console.
• Large-Scale Events: For extensive events, using multiple mixers can improve workflow efficiency and provide better control over numerous audio inputs.
• Redundancy: Having a backup mixer offers a safety net in case of equipment failure during a critical performance or recording session.

Methods for Running Two Mixers Simultaneously

There are several ways to connect and operate two mixers together. The optimal method depends on your specific needs and available equipment.

1. Using a Mixer as a Submixer

This is a common and straightforward approach. One mixer handles a subset of your audio signals, acting as a submixer. Its output is then fed into a main mixer, which handles the overall mix.

• Connection: Use a balanced cable (XLR or TRS) to connect the main output of the submixer to an available input channel on your main mixer.
• Advantages: Simple setup, efficient workflow for managing complex audio setups.
• Disadvantages: Limits the number of channels available on your main mixer.

2. Utilizing a Multi-Channel Interface (Audio Interface)

An audio interface with numerous inputs and outputs offers superior flexibility. Each mixer connects to the interface, allowing you to route audio signals between them and your recording software or other audio devices.

• Connection: Connect the main outputs of each mixer to separate inputs on the audio interface. You can then route audio signals within the interface's software mixer.
• Advantages: Highly flexible routing options, allows for recording and digital processing, ideal for larger-scale productions.
• Disadvantages: Can be more expensive and requires familiarity with audio interface software.

3. Employing a Matrix Mixer or Switcher

For advanced scenarios involving many audio sources and mixers, a matrix mixer or audio switcher provides unparalleled control over audio routing.

• Connection: Each mixer connects to the matrix mixer, which allows you to route signals between mixers and other audio devices with extensive flexibility.
• Advantages: Unmatched routing capabilities, facilitates complex audio configurations, often includes features like monitoring and metering.
• Disadvantages: Significant cost, higher level of complexity.

Essential Considerations

• Signal Levels: Pay close attention to signal levels to prevent clipping or distortion. Proper gain staging is crucial when combining audio from multiple sources.
• Grounding: Ensure all your equipment is properly grounded to avoid ground loops and hum.
• Cable Management: Neat cable management is crucial to avoid tangles and potential signal issues.
• Monitoring: Set up adequate monitoring points to hear the combined output from both mixers.

Troubleshooting Common Issues

• Hum or Buzz: Check grounding, cable connections, and signal levels.
• Distortion: Reduce input gain levels on your mixers and audio interface.
• Feedback: Adjust microphone placement, gain levels, and EQ settings.

Conclusion

Running two mixers simultaneously presents unique opportunities for managing complex audio situations. By understanding the different methods, employing best practices, and proactively addressing potential issues, you can effectively leverage multiple mixers to enhance your audio production workflow and achieve professional-sounding results. Remember to choose the method that best fits your specific needs and budget. With the right preparation and approach, you'll be mixing like a pro in no time!
