imgSafety Harbor, FL (July 10, 2013)—In his 12-year career, Jonathan Loeser has risen in the ranks, engineering for Olivia Newton John, Prince, and Colbie Caillat before becoming FOH engineer for the multi-platinum country group Rascal Flatts. On hand with Loeser for all of the Rascall Flatts’ shows is Metric Halo’s sound analysis software, SpectraFoo, paired with a Metric Halo LI0-8 interface.

Tuning the system requires dealing with Rascal Flatts’ somewhat unconventional stage setup. “We have an extensive thrust, and there’s an apron in front of the stage that makes it hard to fill the gaps that it creates,” Loeser explained. “I have some under-hangs that do the trick, but they are touchy. For this tour, I’ve added two Audix measurement mics. During system tuning, I’m able to place them in the questionable zone of seating, then, using SpectraFoo, I can actually see what the down-fills are doing.”

During tuning, Loeser’s custom SpectraFoo screen includes full-frequency transfer functions on the wireless RTA mic, as well as on the thrust mics. He also includes high-resolution, low-frequency transfer functions to properly align the subwoofers. For the show itself, Loeser flips to another custom SpectraFoo screen. He moves the Audix microphones to a near-audience position on stage that is also used by the monitor engineer for crowd capture.

Previously, Loeser had used sound analysis software primarily for its transfer function. “With SpectraFoo, I’m still able to do that, of course, but I’m also able to do so much more,” he said. “SpectraFoo is very flexible. For example, when I do a time capture, I can move the point that I want to correlate with, which makes it a much more useful tool. Once I learned how to compose and save snapshot window sets, I configured SpectraFoo to show me everything I want to see for tuning and, separately, for the actual show.”
