| The Audio SRS is made up of
three sub systems: Main House System (MHS), Stage Monitor System (SMS)
and 70-volt Campus-Wide Audio System (CWAS).
The House Sound system currently has 24
input lines from the stage that are passed to the mixing board in the
sound booth using a ProCo 24x4 channel snake. The four snake
returns are passed from the mixing board’s four aux sends back to the
stage for the Stage Monitors. The main mixing board is a Mackie
24x8 board and a Mackie 24e extension giving 48 total input channels and
is used for a front of house sound reinforcement mix, monitor mix and a
recording mix.
Inputs include a Shure MX412 with a 184
head podium microphone and an AKG baptistery microphone. The Choir
microphones are 2 Rode NT1-A microphones. The Ensemble uses 1 Rode
NT1-A microphone. The wireless microphones include the following:
a Shure SM58 hand-held VHF, a Shure 184 lapel with a VHF belt pack, a
Shure 183 lapel and two Countryman E8 head-set microphones using UHF
belt-packs.
The 8 cordless microphones (4 additional
wireless microphones will be purchased in the near future) are passed
through eight dbx 286a microphone preamps and then passed to the Mackie
24x8 mixer via an eight-channel snake.
The front of house sound reinforcement
mix is a two channel mono mix that is passed to a Rane SM26B six-channel
splitter. From there, the six channels are fed out as follows:
- Channel 1 and 2 are fed to the House
speaker management system.
- Channel 3 is fed to the SoundMate
hearing impaired system.
- Channel 4 is fed to a 70-volt
campus-wide speaker system.
- Channel 5 and 6 are fed to the CCTV
video distribution system.
A pair of Crown CE1000 amplifiers
mounted under the stage power the ElectroVoice Sx80B Stage Monitor
System (SMS) speakers located on the stage. A Furman PL-Plus power
conditioner powers and protects these amplifiers. The power
conditioner and the amplifiers are mounted on an aluminum 22-space rack
that is located under the stage.
Signal processing is performed by a dbx
DriveRack PA speaker control system that acts as a real-time analyzer,
compressor, limiter, equalizer and crossover.
A Crown CTs1200 amplifier powering the
main house loud speakers and a Crown CE2000 amplifier powering the
Subwoofers provide amplification. A Furman PS-PRO power
conditioner powers and protects these amplifiers.
The speaker system for the Main House
System (MHS) consists of a pair of EAW MK2194e 2-way full range main
house loud speakers using an OmniMount 60.0 WA wall mounts along with
safety wires and a pair of JBL MPro MP418S 18-inch Subwoofers mounted to
either side the Crow’s Nest facing the stage.
A Behringer UB1002 mixer controls the
70-volt Campus-Wide Audio System (CWAS). This mixer outputs a two
channel mono signal to two Radio Shack 20-amp 70-volt amplifiers.
One amplifier powers the speaker array in the old building and the other
amplifier powers the speaker array in the new building. The
speakers are mounted in all of the hallways, bathrooms and the
fellowship hall. A Shure 55SH Series II Vocal Microphone is used
for public address statements. A Tascam CD301 CD player is
dedicated to the CWAS. This gives the flexibility to play a CD to
the speakers in the CWAS without affecting the Main House SRS.
Likewise, anything coming from the Main House SRS can be routed to the
CWAS speakers.
The Television sets in the Nursery
Check-in Room and the Choir Room (which is used for crying children and
nursing mothers) uses the sound from the CCTV system that is independent
of the audio signal being fed to the CWAS. If the CWAS audio feed
is turned off, the television sets will still have an audio signal being
fed to them. |
