Powersoft amplifiers, offering high efficiency and green design, were recently installed at the newly renovated Beacham Theater to power the EAW KF740 house P.A. system. The Beacham Theater is a 1,250-capacity live music venue and state-of-the-art nightclub in the heart of downtown Orlando, Fla.

The owners retained Heavier Than Gravity, a local design and install firm in Orlando, to handle the transition. Jeff Kenney, owner and designer of Heaver Than Gravity, specified a complete EAW house system featuring KF740 line arrays. When looking at power amplifiers, Kenney says he wanted to make sure he was powering the system with substantial and reliable amplifiers.
“The rig needed substantial power and the amplifiers competing with Powersoft just didn’t make any sense,” Kenney explains. “While I’ll admit that it is nice that Powersoft amplifiers are only 1RU and extremely efficient, performance is key—and that is what won the day. We have more than enough headroom and have never had to push the system. They are amazing amplifiers.”
Kenney specified nine Powersoft K Series amplifiers—two K3, two K6, four K8 and one K10—to power the main P.A. A Powersoft M14D powers the four loudspeakers that serve as lip fills on the stage while a Powersoft M30D powers the loudspeakers that cover the mezzanine/upper balcony.
Kenney also used two Powersoft K3, four M30D and one M28Q (4-channel) to power stage monitors and stage monitor subwoofers.
“The amps breathe in clean air venting out of the stage, keeping them away from audience air which can be less than ideal for amplifiers,” Kenney says. “I’m not concerned about cooling because we have never had to push the system hard enough to worry about heat.”

Powersoft K Series amplifiers share a common chassis offering worldwide power supply operating range, Power Factor Correction, and they weigh 17.6 pounds in a single-rackspace unit size with DSP, Ethernet and SmartCard options. All models offer more than 90-percent efficiency, deliver a damping factor of >5000 @ 20-200 Hz, and can be equipped for control from Powersoft’s Armonía Pro Audio Suite software.
The M Series features Powersoft's bridgeable, switch-mode, fixed frequency Class-D topology. The standard models are fitted with a suite of protection circuits along with Powersoft's output filter and ripple cancellation network.
The Beacham opened in January 2011. Kenney says he has been extremely pleased with the feedback he has received from bands, FOH engineers and the audience. “At the end of the day, what really matters is if the system sounds good, and it sounds great,” Kenney concludes. “When everyone is happy you know you put together the right system.”
