First Christian Church
This growing congregation is outgrowing their
new campus. The family life
center serves as a gymnasium, fellowship hall and worship center.
The original system was designed in the
fall of 2001
and completed in January of 2003. The worship
minister, had very big ideas: most of which we were able to fit within his
The acoustic treatments were designed along with the architect, Chuck Ackers of
Ackers and Associates, Crawfordsville, Indiana. The splaying of the
side wall and the application of 2" thick "Tectum" on the back wall
of the room have provided a controlled room that supports congregational
The original tight pack cluster was assembled from
JBL components. Each has two 15" woofers and a 60 x 50 degree
horn with a 1.5" throat compression driver.
The new expanded array is assembled from EAW
three way install systems. Each has a pair of 12" woofers,
8" mid range cone and 1.4" throat compression driver. All
elements are horn loaded.
The sub woofers are custom built
systems from Concert Systems LLC of Southbend Indiana. They were designed
to provide a very deep sound while retaining a high impact level.
Gary Lavengood designed the boxes to fit into the space under the
platform. The original sub woofer system had two single 18" JBL
woofers. The new sub woofer arrangement added two quad 12" sub woofer
systems. The 18" subs are processed and amplified separately from the
12" subs. The results are increased out with lots of punch.
A trio of two way front fill speakers were
built by Concert Systems LLC. Each low profile box has two 6" woofers
and one 5" ribbon driver. Each box has a very short but wide coverage
pattern. This serves the front two rows of seating very well.
The 40 channel Soundcraft mixing
console is right at home in the elevated control booth along with the video and
lighting controls. A few components were reused from the congregation's
old system, most of these are in the control booth including wireless
microphones, an effects processor and recorder.
New Crown CTS series amplifiers were used to
add more power to drive the system. The high efficiency amplifiers do not
require more electrical power than the original system.
The 61 space amplifier rack is
located in storage room to the right of the platform. A 70 volt line
speaker above the rack allows monitoring in the back room. A pair of digital
system processors control the entire main system, and the sub woofer
The worship team uses in-ear monitor systems
now, so the stage monitor volume is greatly reduced. The total of on stage
wedge mixes reduced from four to two.
