Audio vs. Video: When Two Worlds Collide

Audio vs. Video: When Two Worlds Collide

Stagewide screens prove to be an audio obstacle for designers who get creative with speaker options at a California church.

New Venture Christian Fellowship is in Oceanside, Calif. The church's 1800-seat sanctuary has become an immersive worship experience after an extensive renovation and A/V overhaul that includes stage-wide IMAG screens. But those visual enhancements made speaker placement difficult.

Olympia Wash.-based integrators CCI Solutions, was hired to design the system. As Rick Boring, Senior Systems Consultant for CCI explains, seamless networked audio performance was a major priority, as well as the speakers not interfering with sightlines to the stage-wide video screens. “A line array was pretty much out of the question,” says Boring. “No matter where we would have placed it, we were going to be blocking someone’s line of sight. So we needed enclosures that weren’t too tall, and had great pattern control.”

The audio system includes a cluster of four Renkus-Heinz ST9-94R three-way self-powered loudspeakers, augmented by five ST7M94R three-way systems for delays. “The pattern control on the ST-Series is very accurate and we’re only putting sound where it’s needed,” Boring remarks.

To reduce low frequency build-up and comb filtering, Boring created a cardioid sub array. Four Renkus-Heinz DR18-2R self-powered dual 18-inch subs are flown over the stage firing toward the congregation, two more units firing toward the stage. “It created a great cardioid pattern - excellent rejection on the stage and consistent low-end across the congregation,” Boring says.

The overhaul also included edge-blended video, sophisticated LED lighting, and a networked audio system based around Renkus-Heinz ST-Series loudspeakers.

Boring concludes, “I’m really pleased. We’ve created an incredible AVL system, and it performed magnificently. The congregation experiences a powerful worship experience.”
