In Episode 303, Sean and Andy are joined by Robert Kuijpers, coming to us straight from the Netherlands to share stories and tips from his extensive experience in the “guerrilla audio” world of fast-moving music festivals.

Robert has been immersed in the live music industry since age 10, starting playing guitar and working in a guitar local shop where he developed a passion for electronics and signal flow. Over the years, he played in various bands while honing his technical skills to make himself sound better, which led naturally into live sound work.

A chance encounter with the band Flairck inspired a career shift into professional audio, eventually leading to a co-ownership role at MPS Audio, supporting international music theater tours. Since COVID and Brexit, Robert has been freelancing, specializing in troubleshooting, FOH/MON mixing, and complex corporate productions.

In Episode 299, the hosts are joined by Jim Reed, RCF USA’s Manager of Installed Sound and System Design, for a wide-ranging conversation that includes pivoting from a career as a musician and front-of-house engineer to a job on the manufacturer side in live venue installations, as well as sharing advice for production folks who get asked to help consult on installations, and those who might be looking to make a shift away from freelance/touring work as life and priorities change. This episode is sponsored by Allen & Heath and RCF.

Jim also shares stories about RCF’s work on the massive PA overhaul for the Indianapolis Motor Speedway, including designing a custom loudspeaker to meet the unique needs of the project, and then turning that loudspeaker into a widely available commercial product.

From the start of his time with RCF in sales and products support, Reed has drawn upon a history in the audio industry that includes work as an A1 audio technician, front of house engineer, and installation project manager for several A/V companies. With a primary focus on the installation and larger production company markets, he developed a range of training and instructional materials, including videos and in-person training seminars, covering topics from basic audio theory to system design. His work also extends to on-site product demonstrations and sales training seminars for some of the largest A/V retailers in the U.S.

Over several years with RCF, Reed has designed and managed more than 1,500 sound systems for a range of applications, from community theaters to Broadway productions, chapels to cathedrals, and community sporting facilities to professional stadiums and arenas.
