East View Christian
Jordan Audio Consultants now has 5 audio
systems, 3 video presentation systems,, 1 Image Magnification system and 2
additional acoustic treatment projects in the Eastview building. Some
of these systems are small classroom sized projects, others are large
meeting room projects.
Audio and Video Project
EVCC has moved to a new campus in 1999.
The original 1600 seat facility had a system designed by a consultant out of
Chicago and built by a contractor from Peoria. Although the system
functioned adequately, it no longer met the needs of the growing
congregation. In 2006 the front section of the balcony was finished
out with 400 additional seats.
The congregation is still growing and the
extra space at the rear of the balcony was needed for 600 additional
seats. It was always known that the present sound system could not
handle these additional seat. It was decided that instead of just enlarging
a system that no longer met the musical needs of the worship ministry, a
major update and upgrade was in order.
The original speakers (EAW), amplifiers
(Crown) and processing (Crown, Shure and dbx) were all retired, along with
the speaker wiring.
BOX - This system was wired with 12 gauge THHN. This is very good wire
for 60 cycle electrical service. It is an awful waste for audio
systems. The cable acts as a choke for high frequency content.
This system acted like it had no tweeters. Turning up the high frequency
controls on the console, made only minor effect. - SOAP BOX
The existing Midas 2000 console and all
stage monitoring and micing systems remained.
The new system uses Electro Voice VLC line
array systems. The estimated maximum spl is 115 dB.
Two 9 box, triamplified arrays of 281 and
291 systems address the 1600 seats on the main floor. These systems
use an 8" woofer for low frequencies,, and 8" woofer for mid frequencies,
and a Hydra horn and dual compression drivers for high frequencies.
Tow 5 box and two 7 box biamplified arrays
of 181 and 191 systems address the 1000 seats in the balcony. These
systems use an 8" woofer for low frequencies and a Hydra horn and dual
compression drivers for high frequencies.
A group of Evid 4.2 speakers were
installed beneath the balcony, above the last two rows on the main
floor. These wide dispersion systems fill in the areas not directly
covered by the line arrays.
Three arrays were added for flying sub
woofers. The center array has 3 enclosures. The two outer arrays
have 2 enclosures each. These subs have three 12 woofers. Two
are aimed forward. One is aimed backward and powered separately.
The effect is a cardioid pattern subwoofer system. The results are
very good. This approach keeps the very low frequency energy in the
house and off of the stage.
New Crown CTs series amplifiers were
installed for the triamplified and biamplified line arrays. New Crown
MacroTechi series amplifiers were installed for the biamplified sub woofer
An Electro Voice Net Max 8000-1500 digital
system processor was added for processing the whole system. Finite Impluse
Responce (FIR) filters were assigned for the line array boxes.
The results are exceptional.
It is hard to take pictures of black speakers hanging in a black
ceiling. You have to look really hard.
