Powersoft amplifiers control sound at Grace Church, Texas

Powersoft amplifiers control sound at Grace Church, Texas

Powersoft amplifiers have been incorporated into the new installed sound systems at both campuses of Grace Church in Houston, Texas, US, 
 Located in the neighborhoods of Garden Oaks and Humble, both installs – coming as upgrades to existing systems – were handled by Houston-based design, installation and consultant firm Covenant Communications Corporation. 
 At the Garden Oaks campus, six two-channel Duecanali 3904 DSP+AESOP amplifiers were deployed. These power a flown system of five JBL VRX900 Series line array modules per side, with one balcony delay per side. In addition, a single two-channel Duecanali 5904 DSP+AESOP amp drives a pair of Sound Bridge 7218SWX dual 18-inch subwoofers under the stage. 
 The Humble campus features six two-channel Duecanali 3904 DSP+AESOP amplifiers, driving an LCR configuration comprising four JBL VRX932LA-1 modules per hang. A single two-channel Duecanali 5904 DSP+AESOP amp provides power to four Sound Bridge 7218SWX subwoofers flown two each side above the stage. Meanwhile, two four-channel M50Q HDSP+ETH amplifiers provide power to the JBL SRX712M stage monitor speakers at each campus.
 Powersoft’s Armonía Pro Audio Suite is used for monitoring and control of the amplifers on the network. Software control of the company’s Active Damping Control allows a slider around to compensate for the speaker cabling lengths and variances of some of the existing wiring to make adjustments to the Sound Bridge subs. 
 Rounding off the system is an integrated SmartCard reader/writer on each amplifier, enabling firmware updates and preset storage to be managed via a slot in the front panel. This allows the amplifiers to be updated from the front panel without affecting the network.
 “Their [Grace Church’s] system was a little bit underpowered, so we’ve significantly increased the amount of power per speaker, and given them more circuits so that we can apply more gain shading,” said Joe Smart (pictured right), sales manager at Covenant Communications. “With all of the control we have now we were able to improve the clarity and the front-to-back coverage with a lot more clean headroom. We have also significantly reduced the rack footprint. The customer is really pleased.”
