The popular one-day rock festival held in Frisco, Texas, EdgeFest, has used Powersoft’s K series amplifiers to power its main stage.
This year’s 22nd annual festival—which took place on April 22nd—saw the 30,000 capacity FC Dallas Stadium fill up to see the likes of The Black Keys, Garbage, Cake, Cage the Elephant, Arctic Monkeys, Neon Trees, Civil Twilight, Switchfoot and Aranda perform.
As for the previous four years, it was put to Dallas-based Gemini Light Sound & Video to provide the production for the massive event of which key was the main stage.
In the end the rig they set up for the main stage included a total of 52 EAW KF740 modules. 18 of these were flown per side in the main system plus eight per side for the extreme side hangs. To provide front fill, Gemini included additional EAW KF730 boxes.
Taking care of the low end, Gemini utilised 40 EAW SB1000z subwoofers—which were ground stacked 20 per side.Article continues below
However, for amplification duties they relied upon Powersoft’s K series.
“We used the Powersoft K2s and K3s on the tops, and we used the K3s on the SB1000s,” explained Gemini’s System Technician, Chad Cain.
The drive processing was once again handled by kit from EAW, added Cain, with their UX8800 DSP units supporting the rig.
Gemini has only recently switched over to Powersoft tech in the last 2 years. According to Cain, the K2 and K3 amplifiers offer a number of advantages over the company had previously used.
“One reason we went to Powersoft amps was the light weight and the size of them,” explained Cain. “We can get a lot more power out of a lot more usable space, so our racks are smaller and lighter.”
This was no small improvement for the Gemini team. Not only does size and weight lead to savings in that area, it also results in real savings in transportation and fuel costs as well as crewing.
“We went from using an amplifier that weighs 80 pounds,” continued Cain, “with four of them running eight boxes, to six Powersoft amps, weighing 26 pounds each, running 12 boxes. That has significantly cut down the weight of the racks.”
The K series amps also take up less space than the previous models used by Gemini. This is because the K2 and K3 amplifiers are only 1 rack unit in height.
EdgeFest provided an ideal opportunity to prove the worth of the Powersoft and EAW tech. Working flat-out in the blazing Texan sun certainly tests any rig to the max.
“That those amps and those speakers can be beat down that hard for that long and come out without any failures, that’s a good deal,” Cain adds. “That’s what you look for, and that’s exactly what we got out of these amps and boxes.”
EdgeFest is promoted by Dallas-Fort Worth area radio station 102.1 FM the Edge (KDGE).
