Trial and Error – Considerations in System Design from a FOH Engineer
Like most things in our industry, learning the behaviour of a sound system takes some trial and error. Understanding what you like does also.

When I started touring, I had no clue what was really out there. I had tried one brand of speakers in a fairly contained environment, and had read Bob McCarthy’s Sound Systems: Design and Optimization book, but had yet to gather true experience to be able to guide my teams with any real opinion. As I navigated the world, it became clear how much variety there was. I started to gain opinions as time continued, but struggled describing what I was hearing or why. Advancing shows felt like a huge obstacle since I still lacked practical application and wasn’t sure how to communicate my experience.

Repetition and analysis have helped me to decide what I want in a system (when I’m given resources to carry one,) and how to conceptualize it. I could break down my observations into data in this blog, but this is just intended to interpret the decisions I make, which ultimately boil down to how I feel when I mix on a system. I have taken accountability by attending classes, reading, and watching videos, so that I am capable of understanding what is happening mechanically that influences the results, and can communicate with systems engineers as needed. However, I am ultimately concerned with what my ear prefers, in which I’m asking myself questions such as:

  • How do the speakers reproduce any given instrument, such as lead vocal, drums, or lead instruments?
  • Is there distortion? Is it linear?
  • Do I want a blank canvas, perhaps something that feels “honest,” or does the box have an implied tonality? Is there phasing and smearing influencing the character or depth of the sounds?
  • How does compression feel on it? Is this something I’m concerned about with the show we’ve prepared?

On top of being able to make qualitative observations about a PA, it equally became necessary to understand the tools at hand. Most modern systems utilize their own software with tools that assist you in the final product. L-Acoustics, Meyer, and d&b, for example, all have varying approaches, and being able to understand those tools can help you determine why you’re hearing what you’re hearing, and provide insight into how to approach it. Also invaluable are the systems engineers who know how to turn expectations into a tangible end result.

These were definitely not concepts I was familiar with initially, but when comparing mixes on PA du jour, I was able to quickly familiarize myself with what I was hearing out of different boxes. Being able to identify these trends have made me comfortable as a mix engineer. Most importantly, being able to recognize trends between the systems has improved my mixing greatly because I was able to begin anticipating the shifts in my mix system to system, night to night. This isn’t an all-inclusive guide or necessarily actionable, just simply considerations for qualifying your experiences. At the end of the day, use your ears and be observant of how you feel.

The mission of SoundGirls.org is to inspire and empower the next generation of women in audio. Our mission is to create a supportive community for women in audio and music production, providing the tools, knowledge, and support to further their careers. SoundGirls.Org was formed in 2013 by veteran live sound engineers Karrie Keyes and Michelle Sabolchick Pettinato and operates under the Fiscal Sponsorship of The California Women’s Music Festival, a 501(c)3 non-profit organization. In 2012, Karrie and Michelle participated in the “Women of Professional Concert Sound” panel at the AES Conference in San Francisco. The panel was hosted by the Women’s Audio Mission (WAM) and moderated by WAM founder Terri Winston. Terri brought together five women working in live and broadcast audio. The groundbreaking panel (which also included Jeri Palumbo, Claudia Engelhart and Deanne Franklin), provided young women and men a glimpse into life on the road, tips and advice, and a Q & A with the panelists. More importantly though, was how incredibly powerful the experience was for the panelists. We had all been in the business for 20 years or more, yet most of us had never met before that day and within minutes we bonded like long-lost sisters. We were struck by how similar our experiences, work ethics, and passions were and wondered why our paths had never crossed and how our careers would have been different had we been there to support each other through the years. Each of us are strong on our own, but together we were even stronger and a powerful force. We were empowered. Each of us had been asked hundreds of times in our careers: Are there other women doing sound? How did you get into sound? How would a young woman go about getting into sound? Through creating SoundGirls.Org, we hope to establish a place for women working in professional audio to come for support and advice, to share our success and failures, our joys and frustrations, and for empowerment and inspiration.
