Next SBE Chapter 59 Meeting

When:  Wednesday, March 11, 2015

Where:  Legacy Christian Center Blue Valley Campus; 14301 Metcalf Avenue; Overland Park, KS 66223

Gather at 11:45 a.m. for lunch (at Sunset Grill) and the SBE business meeting, followed by the tour at 1 PM


Facility Tour.  Shane Rushik from Legacy Christian and Dan Stark of Stark Raving Solutions will give a tour and demo of the state-of-the-art Legacy Christian Church campus at 143rd & Metcalf which is in a recently renovated former Dillions grocery store building. Legacy Christian Church is a multi-site church with the main campus located at 101st and Antioch. They currently have three satellite campuses, each satellite campus has local leaders, music and receives the message from a time-shifted multi-program transport stream via an IP recorder over a campus wide WAN. Each campus receives a locked down ‘virtual pastor’ at near real-size (21 foot wide at 143rd & Metcalf campus) with IMAG and graphics on side screens. Stark Raving Solutions worked on this project from the planning stages with the owner and architect through installation with the general contractor, owner training and commissioning with ongoing support.

We will meet at the Sunset Grill for lunch at 11:45. The restaurant is on the south-west corner of the complex where the church is located. We will walk across the parking lot and meet at the church at 1 PM for the tour and demos which will last approximately an hour.

Sunset Grill Address:  14577 Metcalf; Overland Park, KS  (ph: 913-681-1722)

More info about the facility:

The campus at 143rd & Metcalf is a renovated Dillions grocery store. Currently the main worship space is configured in a double gymnasium space, with sports activities during the week and reconfigured as a worship space on weekends and events. The space utilized an acoustic plan that provides a great sound during services, yet has a live feeling for sporting activities. The audio system is built on digital audio networks to facilitate a portable sound and lighting booth with digital connections to wall plates to allow fast and easy booth relocation as needed. The digital audio processing system has modes to allow a reduced audio system for activities during the week without the need of connecting the audio booth. The audio system is operated at levels up to 95 db during worship services.

The video system includes a triple wide background projection screen with an aspect ratio of 38:9 fed by live graphical content. Two 9’x16’ side projection screens show local graphics during worship, and IMAG from the MPTS during message. A 21 foot wide 16:9 screen projects the ‘virtual’ pastor during message. A 14’ wide projection screen is on the back wall to show ‘confidence’ or prompting information to the performers on the platform. The video system is based on an HD-SDI infrastructure with routing and production switchers.

The Missouri House Bill 1582 “First Informer Broadcasters Act” will have to be taken up this fall as the Missouri Legislature ended its session on Friday, May 16th (2014).  The bill “establishes certification (for) radio and television broadcasters under the "First Informer Broadcasters Act" in order to prepare for and respond appropriately to an emergency or disaster.”
