Ep18 Building a FOH Mix Pt 3: Gates and Compressors

Key takeaways

Understanding the role of gates and compressors is vital for creating a polished front-of-house mix.
Gates can significantly reduce unwanted noise and feedback, particularly from low-end signals such as drums.
Compression is essential for controlling levels and adding harmonic thickness, especially in live sound environments.
Using group compression can help maintain balance and dynamics across multiple channels rather than compressing each one individually.
Listening critically and making intentional decisions about dynamics processing helps avoid the pitfall of over-compression.

Summary

Gates and Compressors Overview

The episode dives into various dynamics processing techniques used in front-of-house mixing, specifically focusing on gates and compressors. It serves as a continuation from previous discussions, emphasizing the importance of these tools in achieving a polished live sound mix. The hosts reflect on their experiences and share insights into the nuances of using gates and compressors effectively.

Understanding Gates

The discussion kicks off with an explanation of gates, their basic controls such as ratio, threshold, and range, and how they function to reduce quieter signal levels. The hosts highlight the importance of using gates on specific instruments like kick drums and toms to control low-end feedback and improve clarity in a mix. They also touch on the relevance of settings like attack, hold, and release when shaping sounds and transient responses.

Compressors in Live Sound

Moving on, the hosts discuss the role of compressors in live sound mixing. They explain the essential controls of a compressor, including threshold, ratio, make-up gain, attack, and release. The conversation emphasizes how compressors can control levels, smooth out dynamics, and add harmonic richness, which is especially useful in live settings where feedback is a concern.

Practical Applications of Dynamics Processing

Practical examples of dynamics processing are shared, illustrating how compression is applied to various instruments such as vocals, bass, kick drums, and snare drums. The hosts provide insights on using group compression for tracks like drums and vocals, emphasizing the benefits of controlling multiple channels together rather than individually, which helps maintain the mix's integrity and dynamics.

Best Practices and Tips

The hosts wrap up by discussing best practices for using gates and compressors in live sound mixing. They share tips on avoiding over-compression by applying dynamics processing purposefully and emphasize the importance of communication with musicians. Notably, they remind listeners to trust their ears in deciding when compression is too much and maintain a sense of dynamics in the overall mix.

Show notes

Yet another continuation of the previous episode, in part three we jump into dynamics. Not just the basics of how gates and compressors work, but some of the many ways to use them, and even how we all differ on our uses of each. Compression in mixing is one of those dark arts that can be understood but somehow we all use it differently. Enjoy this one, we could have gone for hours.--- Support this podcast:
