Ep14 FOH System Design

Key takeaways

Understanding speaker types and their intended coverage is vital for effective FOH system design.
Achieving comfort and consistency in sound involves making strategic compromises among speaker types and placements.
Front fills are essential to ensure the audience closest to the stage receives quality sound without being overwhelmed by subs.
The dynamics of sound system design require consideration of room shape, audience distribution, and potential sightline issues.
Personal experience, ear training, and use of tools like RTAs and FFTs are crucial for successful sound mixing in challenging venues.

Summary

Introduction to FOH System Design

The episode kicks off with the hosts, Brandon Draper, Joe Santarpia, and Ryan John, introducing the theme of the day: front-of-house (FOH) speaker system design. They humorously dive into the complexities involved in pointing speakers effectively to ensure the best sound experience for concertgoers.

Types of Speakers and Coverage Goals

The hosts discuss various types of speakers, including point source and line array systems. They explore the nuances of PA coverage, emphasizing the importance of consistent sonic quality across various seating positions in a venue. Key concepts like SPL coverage (volume consistency) and frequency response (tonality) are highlighted, noting the trade-offs that may need to be made when designing a sound system.

The Complexity of Sound System Design

The discussion shifts to the intricacies of sound system design, including how to balance multiple types of speakers within a venue. The guests talk about optimizing speaker placement to achieve even coverage while considering factors like audience sight lines, venue shapes, and the need for additional speakers like front fills and subs to enhance the overall sound experience.

Subs, Front Fills, and Other PA Considerations

A significant portion of the episode is devoted to discussing subwoofers and front fills, including their crucial roles in sound reproduction. The hosts unpack the technical aspects of subs and how they can create dramatic listening experiences when deployed effectively. Tips and tricks for managing sound pressure levels (SPL) are shared, stressing the importance of proper speaker placement to avoid feedback and ensure the audience's satisfaction.

Practical Tips for Mixing in Challenging Environments

The final discussion revolves around practical advice for audio engineers working in less-than-optimal conditions. The hosts share personal anecdotes highlighting the importance of walking the venue during soundcheck, using headphones, and understanding room acoustics. Techniques for addressing challenges when mixing from unconventional front-of-house positions are also explored.

Show notes

In this episode, we dove into the basics of the FOH speaker system design. This topic as a whole spans entire careers, so do take our basic information here with a grain of salt. We talk through speaker types, coverage goals, placement, and how to integrate subs, front fills and other PA into your setup. --- Support this podcast:
