Front-of-house engineer Jon Lemon, a veteran of tours with such bands as Oasis, Nine Inch Nails, Beck, The Cure and Depeche Mode, is currently on the road with the recently reunited Motley Crüe. For the tour, he’s using a Metric Halo Mobile I/O rig running SpectraFoo analysis software.
According to Lemon, the setup is fully complementary with his preferred digital mixing console and digital loudspeaker processors, allowing him to optimize the sound system in each venue on the tour in a matter of minutes.
"I use SpectraFoo every day for lining-up the system," he says. "When you use line arrays, you have that problem of lining up the bass stack on the ground to the flown speakers and the side hangs. I've been a SpectraFoo user for a long time now, so for me it's very fast. I'll time-align the bass stacks and the flown part of the system first, using music and SpectraFoo's transfer function. That literally takes two minutes. From there, I'll noise the system using the Spectragram page and find any room anomalies."
An early adopter of digital audio technology, Lemon typically tours with a digital mixing console. "I try to keep everything in the digital domain. I come out of the console into the Metric Halo Mobile I/O 2882+DSP and then out of that into my Macintosh laptop running SpectraFoo. I also have a mic for the room going through the MIO.”
Lemon says of SpectraFoo, "It's a really useful tool. You can do it all by ear, but it takes longer and there's some uncertainty. When you know the software is responding correctly and there are no reflections, and obviously there is a bit of experience involved with setting everything up correctly, the software speeds the whole process up. I can pretty easily tune the system in the space of 15 to 20 minutes in most arenas."
