Mastermind Provides Summer Sounds with JBL VTX Line Arrays and Crown I-Tech HD Amplifiers

Regional event production company Mastermind Production Group Inc. of Orange, California has enjoyed a successful summer of high-profile events with its HARMAN JBL VTX line array system and Crown I-Tech HD amplifiers. With an inventory featuring JBL VTX V20 loudspeakers plus S25 and S28 subwoofers, Mastermind has serviced a large number of outdoor productions in recent months, highlighted by the MTV Fandom Awards.

Held at Petco Park in San Diego during Comic-Con International, the 2015 MTV Fandom Awards were hosted by Bella Thorne and Tyler Posey, with performances by pop artists including Flo Rida and All Time Low. The stage was set up in the “Park at the Park” area of Petco Park—a large open area behind the stadium’s center field wall.

The PA system at the MTV Fandom Awards featured a left-right configuration of 10 VTX V20 loudspeakers and two VTX S25 subwoofers flown per side. Twelve VERTEC® VT4886 loudspeakers provided out fill, as well as VIP area coverage.  Twelve VTX 28 subwoofers and additional VT4886 and VRX932LA loudspeakers provided front fill. Two V20 loudspeakers and two S25 per side provided onstage side fill with SRX712M rounding out the monitor package.  Crown I-Tech 4x3500HD amplifiers powered the V20 and VT4886 loudspeakers, while I-Tech 12000HD amps powered all the subwoofers and the entire system was configured using JBL HiQnet Performance Manager™ software.


Later in the summer, hip-hop artist Nelly performed a concert at the same venue, with Mastermind there to deliver a high-impact PA system featuring six ground-stacked V20 loudspeakers per side over three S25 subwoofers per side in a cardioid configuration, with eight S28 subwoofers in the center. Crown I-Tech 4x3500HD amplifiers powered the V20 and S25 boxes, while I-Tech 12000HD amps powered the S28 subs.

Having purchased the VTX components a little over a year ago, Mastermind has delivered consistent, world-class sound for a variety of productions. “The size versus power output is great, the high end is nice and smooth and we get a lot of punch out of the system,” said Chad Griswold, Owner of Mastermind Production Group Inc.


In addition, Griswold has found the simple and flexible rigging of the VTX system to be a significant advantage. “At the MTV Fandom Awards, we modeled the system based off the information we were given, but the stage setup changed a bit when we were setting up,” Griswold noted. “However, it was very easy to modify the angles on the array while it was suspended—we didn’t have to take any of the loudspeakers down to make the necessary changes.”

In addition, Griswold found the I-Tech 4x3500HD amplifiers to be a perfect complement to the system. “Crown has been great with I-Tech HD, utilizing the built in presets for the boxes has proven to be a reliable and stable platform when used in conjunction with the VTX systems and beyond” he said. “The fact that I have four channels of high-power amplification in two rack spaces with full DSP is great.”

Ultimately, Griswold noted that the purchase of the VTX line arrays and I-Tech HD amplifiers ties in with Mastermind’s company philosophy. “We try to treat our clients with the best service possible and make a point of having really high-quality gear, and we aim to uphold that reputation,” he said. “I’m looking forward to getting the system out there for more and more events. A lot of people have the perception that bigger is always better, but these V20 boxes pack a lot of punch.”
