Signal Distrubtion: Calvary Baptist Church
Sep 16, 2014 7:47 PM
New York’s Calvary Baptist Church went from traditional to high-tech with a complete audio/video system designed to bring worship services closer to everyone in the congregation. Thanks to digital cameras and big-screen displays, as well as a variety of switching equipment, everything from the preacher to the choir can be seen and heard from different angles throughout the church. The building itself can also be used for other events and presentations.
Created by Panavid, a local audio/video installation professional, the system uses dramatic videowalls to surround the congregation on three sides. “The church wanted a cutting-edge system that would add video to an elaborate sound system,” says Dennis Mitchell, client relations manager for Panavid. “We designed something that could add a whole new dimension to their services.”
Led by Panavid’s vice president of operations, Rob Loehr, with the help of a team of experts from Kramer Electronics, the system was designed for maximum efficiency and ease of use. Four 55in. LED monitors in a 2×2 pattern form each videowall. The walls display video from three HD pan, tilt, zoom cameras placed around the church, a remote camera, computer-based graphics from a desktop and laptop, and a DVD player. Panavid created breakout rooms in the choir loft, a green room, an overflow area, and the front lobby that would also show selected content on high-resolution monitors. In addition, monitors display content in the nursery, Sunday school and fellowship offices, and at the organists’ area. The video content is managed by a variety of Kramer Electronics switching and scaling products.
The primary switching unit is the Kramer VP-747 ProScale In- CTRL dual scaler seamless switcher with the VP-747T remote control console. The unit’s dual scalers allow video preview prior to sending the signal to the audience displays. Eight inputs accommodate various resolutions, and the scaler provides true seamless transitions between sources. The system also incorporates eight Kramer VM-2Hxl 1:2 HDMI distribution amplifiers and a Kramer VS-88H matrix switcher, which routes the sources to selected displays or all of the displays simultaneously.
For long-distance signal transmission, four Kramer Electronics VM-114H4C combination switcher and distribution amplifiers allow selectable input signals of either HDMI or Cat-5 over DGKat twisted-pair cabling. Several PT-571 and PT-572+ DGKat twisted-pair transmitters and receivers and a TP-50 twisted-pair receiver and TP-121EDID twisted-pair transmitter for computer graphics video signals are used throughout the system.
Two Kramer HDMI ProScale digital scalers—the VM−92 and the VP−434—scale the incoming signals to a computer graphics resolution and output an HDMI signal. Panavid also used Kramer Electronics racks and rack adapters to house the switching and scaling products.
Volunteers quickly caught on to the technology and run the system.
“Calvary Baptist Church is delighted with both the equipment and the excellent service received in this renovation. The quality of our worship has been greatly enhanced,” says Michael Toombs, executive administrator at the church.
