ATK Audiotek Uses JBL Line Array at the 55th Grammy Awards

ATK Audiotek, based in Valencia, Calif., supplied the live sound reinforcement system for the 55th Annual Grammy Awards, held on February 10, 2013 in Los Angeles at the Staples Center. This year’s Awards show was hosted by LL Cool J and featured performances by The Black Keys, Mumford & Sons, Rihanna, Taylor Swift, and others.

The SR system featured left-right columns of 12 VTX V25 full-size line array elements per side for the main P.A., with additional left-right columns of 12 V25 per side for out fill, along with a center cluster of 18 VTX S28 arrayable subwoofers in cardioid mode (two arrays of nine S28 subs each), for a total of 66 VTX loudspeakers. Six VRX932 Constant Curvature loudspeakers served as front fill, with left-right rear delay arrays of eight VerTec VT4889 full-size line array elements each. Powering the loudspeakers were 16 Crown Audio VRack 2000 and four VRack 4×3500. The entire system was configured using JBL HiQnet Performance Manager software. The house sound system at the Staples Center featured VerTec VT4888ADP-DA powered line array elements, and was used to supplement the live sound system with five enclosures from the center end array used for rear upper deck and VIP box coverage.

“This year we used the newest evolution of the JBL line array,” says Jeff Peterson of ATK Audiotek. “The V25 had a very clear and smooth high end which didn’t distract our attention. All of the low-end power we’re accustomed to with the VT4889s was there and then some. The S28 sub is so efficient we never came close to using all of the available power. Tying it all together, Performance Manager gave me all the control and monitoring I needed.”
