First Christian Church
32 years is a long time for electronics. That
is how old the dimming system was for the FCC. Most of the dimmers had quit
working except as a relay. At least they lasted longer than the mortgage.
The sound system was a few years newer, but several parts of it had been in place for
more than 22 years. The video system was about 8 years old and still working
but did not complement the room. It was also very difficult to service.
The main objection from the congregation was that the center projection screen covered up a
stained glass cross behind the baptistery. Now with dual screens, the opening
above the baptistery is clear of any obstruction and cross can be clearly seen.
Jordan Audio was hired to engineer and specify
new audio, video and lighting systems for the sanctuary. There was one other
major concern too - the choir loft. The choir has large cushioned chairs is
fully carpeted and is positioned against a soft wall.
The plan began with adding 1/2" oak veneered
panels behind the choir to create stronger early reflections to help the choir
hear themselves. This work was completed by the choir director who just happens to
also be a finish carpenter. We also suggested removing the carpet in the
loft and changing the chairs, but these ideas were put on hold.
The new look and the improved sound has
created a very positives energy within the choir. The difference is like they
had added several more voices. New high quality choir microphones on
carbon fiber boom arms were added in front of the choir. We retired the two
overhead microphone that never seems to be aimed at right places. The results
are even better than we could have hoped.
The congregation is very pleased with both the
visual and aural results.
In order to accomplish the overhaul of the video
projection system, of placing dual screens lower on the platform and out to
either side, it was necessary to make major changes to the lighting. The four
chandeliers over the platform were removed to storage and 8 pendant canisters
were added. Several additional PAR64 architectural fixtures were added to
improve the face lighting for the whole platform.
New dimmers were installed to control all the
house lights and the new platform lighting. Simple architectural controls were
added at major entries and a simple control console was added in the new AVL
The new lighting system allows the new
projection screens to be saturated with light from the 5500 lumen projectors. A
55" LED video monitor was added on the front of the balcony railing to
allow those on the platform to see what was being projected on the
The sound system is also completely new.
Only a DVD player and a couple of microphones were reused. A new control booth
was built at the rear of the seating on the main floor. It was built by the
choir director, so it matches the wood work in the sanctuary.
Three monitors systems were assembled for use
on the platform. One system with installed speakers surrounds the choir
loft so the singers can hear the preacher and the song leader. A second
system with installed speakers allows the pianist and organist to hear and
provides them a local volume control to turn down any signal that is too
loud. The third system uses moveable floor wedges to accommodate vocalists
and other instrumentalists.
A sub woofer to reinforce the lowest octave of
the musical spectrum. It is hidden behind the vertical stripes on the chancel
wall in the organ speaker chamber.
A main two way overhead speaker array includes
dual 12" woofers and three constant coverage horns with 2" throat
compression drivers. The array is biamplified.
A balcony two way overhead speaker includes
one 12" woofer and one constant coverage horn with 2" throat
compression driver. This speaker is also biamplified.
A new fellowship hall sound system was
also assembled with JBL pedant speakers, a CD/Ipod deck and a feed from
The chancel with the new screens, choir shell and audio system.
A dual 15" sub woofer by Concert Systems LLC was placed in the organ
speaker chamber. That is a 30 year old organ speaker to the right.
The new amplifier rack in the corner of the organ speaker chamber.
The new overhead cluster of speakers use 2" throat compression
drivers and 12" woofers.
The balcony fill speaker uses the same compression driver and woofer as
the center cluster.
New AVL control booth at the rear of the main seating area.
A custom pew back type of monitor system was added in the choir
loft. This picture was taken prior to the oak being stained and
