The recent Fantabuloso “Dos” 2011 at the Allstate Arena just outside of Chicago had Gand Concert Sound (GCS) once again providing audio system support that included a Nexo GEO T tangent array rig.

Artists appearing at the concert included Pitbull, Mike Posner, Lupe Fiasco, Taio Cruz, T-Pain, Jesse J, Far East Movement, David Gueta, and Tinie Tempah.

GCS supplied 21 GEO T4805s and three GEO T 2815s per side for mains, seven 4805s and two 2815s per side for out fills, supported by 28 CD18 subs.

Six NEXO PS10s were used for front fills, with eight bi-amped NEXO PS15s down stage with Yamaha T5n amps and eight NEXO PS15s with Nexo 4x4 NXAMPs. Nexo Alphas were used for side fills.

“We are in our ninth season using the GEO T, being the first company in the U.S. to invest in an arena-size rig in 2003,” states GCS president Gary Gand. “Constant software upgrades have allowed NEXO to stay at the forefront of line arrays.

“Many other companies adopted ‘marketing improvements’ with cute names and smaller boxes. The GEO T was always small but produced SPLs comparable to the bigger boxes. Coupled with their cardioid design and cardioid CD18 subs, we still feel they are the best in their class, and so do the artists.”

GCS chose a Yamaha DME64n digital mixing engine to sum the three mixing consoles at front of house, one of which was a Yamaha PM5D-RH.

Each of the front of house consoles had control of left and right front fills, and aux to feed subs. A second Yamaha PM5D-RH was part of a trio of consoles used for monitors.

“The DME was used to sum left and right to feed out fills for the seating on the sides, and also for room EQ and time alignment,” says Gand. “Interfacing multiple console platforms has always been a challenge, however, the DME64n made using artist-specific consoles a snap, allowing each engineer to tailor various zone options to their own taste.”
