A 3,000 seat auditorium built in a fan shape design with dual mezzanine and a large bi-level balcony. The task of providing even coverage was formidable. Grecco determined that a true LCR system with dual stereo imaging through out the room would conquer the task. To achieve this, Grecco hung three 11 box line arrays with dual-stereo wings in a LCR configuration supported by 16 sub cabinets and 8 front fills.

Products Used:

Center Cluster: (11) Dual 12 inch Self Powered Line Array boxes
Left/Right Cluster: (11) Single 12 inch Self Powered Line Array boxes
Front Fills: (6) 3-way 6 inch Self Powered boxes
Subs: (16) Dual 18 inch Self Powered, (8 in reverse poloraity for pattern control).
Wings (44) Self Powered Wing boxes for reverse left and right imaging.

Constructed as a “theatrical performance” room with a strong emphasis on intelligent lighting and video projection, Celebration Covenant Church’s 5.1 surround sound audio was an obvious format to choose. Grecco designed three 7 box line arrays in front to provide the LCR imaging with dual trap box clusters in the LR and RR positions. Six front fills and six dual 18 subs completed the system. “We are media heavy here at Celebration Covenant Church with nearly all of our video presentations mixed in 5.1. During our live worship, I mix in percussion and effects in the Left-Rear and Right-Rear channels to create a huge atmosphere for our congregants. We love the crystal clear sound from Grecco’s speakers and most especially from the ribbon tweeters which are pure joy to listen to and mix on” says Danny Beaver, audio engineer at Celebration Covenant Church - Frisco, TX.

Using over 300 speaker components throughout Covenant Church’s 2,500-seat auditorium, Grecco employed a sophisticated 21 cabinet line array system with dual-stereo wings set in a LCR configuration. The system also employs 12 dual 18 inch subs, 10 trap boxes in the balcony’s fascia for surround channels, 20 trap boxes for balcony coverage, 4 front fills and 8 monitors. It also boosts one of the first custom made personal headphone systems ever installed in a church (before the launch of Aviom). In addition there are two FM transmitters and personal Walkman-style FM receivers for the 100 voice choir to eliminate 100% of wedge volume from the platform. The system has a total of 72,500 watts of amplifier power providing crystal clean frequency response. Since ribbon drivers present very low amounts of distortion, it is not uncommon for the high-energy worship services at Covenant Church to be operating at 110 dB SPL in the house!

The room is tuned with Whisper Walls ® core and acoustical designer fabric as well as four dual 18 inch cabinets in reverse polarity strategically placed and delayed to help control the low frequency build-up in the room. FOH engineer Stan George states, “Mixing on these speakers is like [taking] a walk in the park. I do not have to overwork EQ to make the instruments and vocals sound as they naturally do. I only wish I had a system like this I could take on the road with me when I am out on tour.”

Hidden behind the fabric in the fascia of the balcony are the 10 trap boxes used for surround sound; four speakers beneath the rear room balcony and three speakers beneath both the left and right side balconies facing diagonally to the stage. The digital console and the audio distribution system can be configured to provide completely separate sends to each of the speakers creating nearly limitless signal patterns (i.e. 5.1, 6.1, 10.1, etc.).

Faith Chapel – San Diego, CA

Faith chapel is a unique installation. It’s basically a large touring rig left in position when the tour was over. A lighting truss was pulled up and permanently left in place with three large ribbon self powered line array clusters. Eight dual 18-inch subs are buried under the stage, with front fills set into the stairs. This is a 2500 seat room, with a ton of PA…

Neotropolis Covenant Church - Carrollton, TX

Neotropolis is the youth facility at Celebration Covenant Church in Carrollton TX. This was previously a movie theater complex that the church purchased and converted into a youth center. The large room seats 500. Grecco used three multi firing point source clusters that provided a true left center right configuration. There are four dual 18- inch subs in the stage front and multiple floor monitors, all of the boxes are self powered.

Word of Life Christian Center, Denver CO

Word of Life has two eight box line arrays behind covered columns on each side of the stage. This is a unique install because the line arrays are actually behind the pulpit and stage area where the singer stand on Sunday. Yet because of the pattern control of this box, there is no gain before feedback issue in this facility. The subs are flown dual 12’s over the pulpit with six boxes facing forward and three inverted boxes firing backwards for pattern control.
