| Montrose,
CO – Montrose Christian Church
recently upgraded the sound system in their Sanctuary to
better serve the music and vocal requirements of their services.
All existing equipment and wiring was removed to make way
for the new system and the mixing desk was relocated to
the rear of the Sanctuary from the enclosed room it previously
occupied (with the old lighting dimmer panel).
A Mackie SR32-4 VLZ Pro mixing console
was installed for all front-of-house mixing duties. The
32-4 VLZ Pro is a true 4-bus designed console with Mackie’s
newly designed XDR microphone preamps that deliver extended
dynamic range to each input making it one of the finest
sound reinforcement consoles in its price range (Suggested
Retail $2,199.00). The existing Shure wireless microphone
systems and the stage microphone package, all of which had
been upgraded earlier by WSPA, connect to the Mackie 32-4
along with audio from video sources and existing playback
CD and tape decks.
A Horizon Stage Series 16x4 audio snake
was installed to provide the microphone and instrument connection
from the stage and to return monitor mixes to the stage.
The main mix from the console is
routed into the Peavey MediaMatrix® X-Frame 88 that
provides vocal and system processing (See the Equipment
Spotlight for features and capabilities of the X-Frame 88).
The flexibility of the X-Frame 88 allows independent processing
of up to eight inputs and outputs for truly customized system
operations. Connected to a host PC system presets may be
easily accessed as the stage program changes.
Main Speaker feeds from the X-Frame
connect to the power amplifiers for the Apogee AE2 and AE-SB
main speaker system that was installed for the Sanctuary.
The main mix processing includes the Apogee AE-2 and AE-SB
factory curves for EQ and crossover, parameters were provided
by Apogee for loading into the X-Frame. Additional processing
to include system feedback control and equalization was
also attached to the main mix signal path. Four AUX sends
from the Mackie also connect through the X-Frame and again
EQ, feedback control, limiting, etc. is provided for the
stage monitor system.
The Apogee AE2s2 is a wide dispersion
full-range cabinet with two 8” woofers and dual horn loaded
compression drivers. With 165 degrees of horizontal dispersion
the AE2s2 was ideal for the 180 degree seating arrangement
of the Sanctuary. To augment the AE2 a pair of Apogee AE-SB
subwoofers were also installed. The AE-SB is a single 18”
subwoofer cabinet that provides the necessary low-frequency
response for the music program. |
Main Rack with MediaMatrix®/Crown Power Amplifiers
Crown CL-Series power amplifiers
provide the power to the main speaker system. The CL-Series
is Crowns new cost-efficient contractor amplifier expressly
designed for the installation market. Amp #1 is operated
in a bridged mono configuration delivering up to 900-watts
of power to the main speaker system. A second CL-1 powers
the AE-SB subwoofers.
As mentioned earlier stage monitor mixes
are fed from the Mackie console to the Peavey MediaMatrix®
for processing. The four mixes are then sent to the back
of stage location over the Horizon snakes returns and into
the monitor amp rack located under the stage. Crown CT-210
power amplifiers were installed in a Raxxess Economy rack
and provide 110-watts of power to each of the stage monitors.
Multiple custom engraved Whirlwind wall plates were installed
Stage left-center-right to accommodate a variety of stage
sets.
The four Klipsch KI-172 stage monitors
are a two-way 8” designed cabinet that can provide up to
113dB continuous output. Constructed of 13-ply Baltic Birch
the KI-172 ensures resonance-free response and long-term
reliability. The loudspeaker sides are slanted for 45 or
65-degree placement for installation where space is limited.
All sound system components were connected
to Furman power sequencing, conditioning and surge protection
devices to ensure that no DC or turn on – off transients
harm the electronics or loudspeakers. A combination of Furman
PS-8 and PL-8 products were used in both the main equipment
rack as well as the monitor amp rack.
Finally, a record signal was routed
through the MediaMatrix® and returned to the cassette
deck at the mix location allowing the service to be recorded
for distribution to shut-ins and future radio broadcast.
