‘A lot of schools, churches, and events centres in Colorado are pretty far behind in terms of audio technology,’ says Lucas Lafferty. ‘We’re really trying to raise the bar and show people how far the technology has come.’

The admission comes from DK Audio Video owner Lafferty, whose company on a mission… Recently Lafferty got a call from Michael Pickering, Music Director at the Community College of Aurora. The college’s 140-seat Larry D Carter Theater was in desperate need of an audio upgrade. Working with Marshank Group representative CJ Lewis, Lafferty put together a sound reinforcement package for the venue featuring an EAW loudspeaker system and Powersoft X4 amplification.

Pickering wanted a system that would handle a wide range of music in the black box theatre. ‘They do everything from acting classes to live theatre to concerts, with music ranging from EDM to piano and vocal, so we needed the power to deliver a deep low end but also the clarity for more dynamic content,’ Lafferty says.

‘Our first Powersoft install was at St Francis High School a couple years ago and I was really impressed with the  clarity and DSP capabilities.’ Pickering and his staff were impressed by what Lafferty and Lewis told him about the X4’s efficiency, knowing that its extremely nominal power draw would be a big money saver for the college, especially when Lafferty explained that it would take only one X4 to handle all the output he need for the system.

For speakers, he and Lewis specified two EAW QX364 boxes and a SBK250Z subwoofer. Suspending the speakers in the lighting grid above the stage well out of sight, Lafferty installed the X4 in the rack in the back of the theatre.

‘They had this huge 8ft rack back there from their previous system, which used six two-rack-space amps,’ Lafferty says. Now we’ve just got the one single-space X4 back there running the whole system. It’s amazing.’

He set up one output each to the main speakers for stereo and bridged the other two outputs through Powersoft’s Armonía software to deliver extra power to the subwoofer.

‘We had so much output from the X4 that I had to set up limiters in Armonía to make sure they wouldn’t blow the system,’ he said. He also took advantage of EAW’s Greybox settings for the X4 to tune its performance perfectly for his speaker system. With the theater already surrounded by thick theater curtains, Lafferty was happy enough with the room acoustics that he did not feel any additional treatment was necessary.

Pickering and his staff in the performing arts department welcomed the upgrade. The X4 has also become a teaching tool for Pickering’s audio technology class. Using the X4’s WIFI interface to control it remotely via iPad, he is able to undo many of the settings for the system, then have his students troubleshoot, fix, and tune the system on their own. Later, he can easily recall Lafferty’s optimal settings via a preset. ‘It’s actually helping train students for the industry.’

With the revitalisation of the theatre complete, the school now has its eye on expanding its system into an larger room nearby. DK Audio Video is slated to handle that install as well, and amplifier choice may be the easiest part of this extension. ‘We’ve all been incredibly happy with the X4, so you can expect Powersoft amps to be the first choice,’ Lafferty reports. ‘We set out to show these kinds of institutions what the next wave of technology could do for them, and
