Church Leadership Training Gets a Lift from A/V Enhancements

Founded in 1969, the Haggai Institute is an international ministry specializing in Christian Leadership training. Over 20,000 church leaders have been educated in over 140 nations. With its corporate office based in Atlanta, GA, the Haggai Institute routinely conducts seminars around the globe. They also maintain and operate permanent, international training facilities in Singapore and on the island of Maui in Hawaii.

In the summer of 2001, the Maui facility underwent a $9 million renovation. Design Plus, a Grand Rapids, Michigan-based architectural firm overseeing the job, brought in Central Interconnect, a full service communications company also based in Grand Rapids, to consult on the planned multimedia audio-visual system. Eventually, however, Central Interconnect was given the green light to design and build the entire integrated A/V system.

"They wanted a state-of-the-art system," said Michael Smith, Vice President of Central Interconnect. "I spent 12 months consulting on the system design, developing drawings and specifications for the bid with Design Plus and the Haggai Institute. When they were unable to reach an agreement with a local A/V contractor, they asked us to build the system. I flew out, took a look, and six and half months later we completed the project."

Training Room Inputs and Outputs

There are five rooms used for training and presentations at the Haggai Institute. The auditorium seats about 120 and is equipped with Shure microphones, a BSS Soundweb sound system with Crown amplifiers, and two Sanyo 3000 Lumens LCD XGA (1024 x 768) projection systems. Strategically-placed floor boxes enable additional connection points to the A/V system, while each seat provides a connection for laptops to the local area network (LAN). The projectors display two side-by-side 100-inch diagonal images generally for the purposes of videoconferencing. One image is from the far end while the other is for the near end. The near end image can be generated from the auditorium's two video cameras, a document camera, VCR, DVD player, laptop, 16mm film, or 35mm slides.

Many of the institute's special events are held in the 200-person capacity dining room. The dining room is equipped with microphones, a sound system, and LCD projector. A podium-mounted ISYS touch panel control system enables the presenter to monitor videoconferences as well as images from a VCR, DVD player, laptop, 16mm film, or 35mm slides. Like the auditorium, there are a couple of floor boxes for additional, external connections to the A/V system.

The three classrooms can accommodate between 30 and 40 individuals. Each room is outfitted with a mix minus sound system, LCD projector, touch panel control system, microphones, a video camera, document camera, DVD player, cassette player, VCR, and desktop computer. Floor boxes to the A/V system and extra connection points to the LAN can also be found in the classrooms.

System Switching and Scaling

Extron System 7SC switchers are in each of the room's podiums for local projection, signal scaling, and distribution. According to Smith, the System 7SC was selected for the Haggai Institute for a variety of reasons.

"We chose the Extron System 7SC because of its internal scaler, the number of inputs and outputs, and its flexibility for configuration," he said. "It was extremely easy to install and program. The fact that all Extron equipment is so easy to interface just makes everything that much simpler."

The System 7SC is a seven input, dual output, multi-format active switcher with a built-in video scaler. It features projector and room control along with RGB and video integration capabilities ideal for permanent installations such as the Haggai Institute. The System 7SC is being used for switching the local sources and for its scaling capabilities. Smith emphasized that every signal routed through the System 7SC gets scaled up to XGA. This is a key feature of the System 7SC as it is able to optimize image quality, maintain maximum image brightness and detail, and match the native resolution of the projectors and plasmas that, in the case of the Haggai Institute, are high-resolution XGA displays. To scale any video input, the System 7SC uses Extron's technologies such as Dynamic Motion Interpolation (DMI™), Accu-RATE Frame Lock (AFL™), and 3:2 pulldown detection for NTSC and 2:2 film detection for PAL.

Also mounted in each podium is an Extron P/2 DA2 MT one input, two output, high-resolution VGA distribution amplifier with audio. With 300 MHz (-3dB) of video bandwidth, the P/2 DA2 MT allows computers with VGA-UXGA graphic cards to send signals long distances for display on monitors or projectors. The P/2 DA2 MT also includes Level and Peaking adjustments to ensure signal integrity over extended cable runs. In some cases, the P/2 DA2 MT is driving signals from the podium as far as 250 feet back to the control room.

The local computer is input into the P/2 DA2 MT. Of the two individually buffered VGA outputs of the P/2 DA2 MT, one goes to the System 7SC while the other goes to an Extron SW2 VGA DA2 A. The System 7SC is also input into the SW2 VGA DA2 A, a combination active switcher and distribution amplifier with audio. While distributing all the signals to the touch panel control system in the podium, the SW2 VGA DA2 A also enables the presenter to switch between signals from System 7SC and the local computer. Conversely, the picture-in-picture touch screen on the podium functions as the local computer's monitor, as well as the system's control panel.

Control Room

The control room is located in the center of the facility with windows looking out to the auditorium and one of the classrooms. It houses all equipment for signal routing, including in-house television distribution, IP streaming to the LAN, and room-to-room integration. There is also videotape mastering and duplication equipment. Twelve monitors allow the operator to oversee the video sources, video cameras, and projector in each room. This is especially helpful when training sessions are recorded.

"They record all their training sessions in video and audio," Smith noted. "They distribute the audio tapes to the participants, and use the video tapes for in-house instructor training." There are a variety of Extron products in the control room integral to the functionality of the entire system. An Extron CrossPoint 88HVA 8 x 8 wideband matrix switcher has been integrated into a plasma messaging system within the control room. XGA sources from around the Haggai Institute are input into the CrossPoint, which distributes signals to plasma displays in the dining room, front lobby, and elevators as well as for CATV and web streaming distribution.

For a camera broadcast system, an Extron SW 6 SV A MX six input, dual output, S-video and stereo audio switcher was installed for switching between the Institute's S-video cameras. It also transports signals to an outside broadcast transmitter and/or an Extron DVS 150 digital video scaler. The DVS 150 upscales the signal to XGA and sends it back through the master control for distribution to any one of the facility's display devices. There's an Extron P/2 DA2 LC, a one input, two output VGA distribution amplifier, being used with a control computer system assigned as a control room alternate. Elsewhere, a control room PC utilizes an Extron P/2 DA4 Plus output to four teleprompters located in the auditorium and dining room.

This same PC can also call up CAD drawings of the Haggai Institute A/V system as well as an electronic submittal folder with product cut sheets formatted in PDF for reference to every single working component of the system. Likewise, Extron has product brochures, user manuals, and specifications formatted in PDF available at www.extron.com.

Final Thoughts

Gregg Lamse, A/V Manager at the Haggai Institute in Maui, has been extremely pleased with the new system. "It's made my job a little less complicated. Instead of sitting behind a mixer in one room and running around to the other classrooms to put out fires, I'm in the control room, watching the monitors, and operating remote video cameras to tape the classroom teaching."

Lamse is also gearing up to expand on the system's flexibility. "The System 7SC switcher is handling almost all of our video switching, but we've barely scratched the surface of what we want to do," he said. "We're still working on expanding our videoconferencing capabilities, distributing signals to hotel rooms using cable TV, and web streaming. 2002 is going to be a very busy year."
