Sound System Overview
Motley United Methodist Church currently has three (3) sound systems:
1. MUMC Sound System: This sound system has components that are permanently
located at the church with the purpose of capturing live and prerecorded sound, playing
an accurate and pleasing reproduction of that sound at multiple locations in the church
and recording the sound for later playback. Accomplishing those tasks requires a
significant amount of sophisticated sound equipment that comprises the MUMC Sound
System. This purpose of this document is to provide an understandable description of
this sound system and how it processes sound.
2. MUMC Organ: In addition the church has an organ that has its own speakers (located at
the back of the Sanctuary) and is not directly connected to the sound system. Organ
music is only captured by the sound system as ambient sound on MICs positioned for
other purposes. Therefore the church organ is not included in this document.
3. MUMC Portable Sound System: The purpose of this sound system is the same as the
MUMC Sound System located at the church, but its purpose is to fulfill that purpose at a
location other than the church. Although many of the components of the MUMC Sound
System can be used with the portable system (MICs, Direct In Boxes, stands and cables),
many of the components are unique to the portable system and therefore this system is
described in a separate document (MUMC Portable Sound System).
It is anticipated that no one will ever read this document cover to cover. In addition this
document is not meant as a training manual for an MUMC sound operator. That training will
still require hands on instruction by a qualified operator. Instead this document is provided as a
reference document that describes the current status of the MUMC Sound System. It can also
be used as a reference document by an MUMC sound operator and/or for future modifications
to the system. The document is divided into the following sections:


Sound System Components
The sound system at MUMC is composed of the following components:
Inputs
Sound is received into the MUMC Sound System from the following sources (reference
Appendix B for the steps to follow when adding a new or moving a MIC in the Sanctuary):
1. Wired Microphones: Currently the church has the five (5) stand mounted condenser
MICs (Choir MICs), five (5) stand mounted dynamic MICs (Solo MICs) and a condenser
MIC mounted to the podium. They can be connected through a series of MIC jacks
located at the left of the sanctuary stage (6 XLR MIC jacks), on the sanctuary stage floor
(one XLR jack under the podium and one XLR jack center stage), to the right of the
sanctuary stage (6 XLR MIC jacks) and in the Fellowship Hall on the wall (4 XLR MIC
Jacks). All the jacks are setup to handle either condenser or dynamic MICs (all receive
phantom power, see ‘Power’). All jacks are connected to the Mackie Mixer except the 4
XLR MIC jacks in the Fellowship Hall, these jacks are connected directly to the Nexia CS
sound processor.
2. Wireless Microphones: Currently the church has three (3) wireless microphones
including an ear-worn MIC (condenser), a handheld MIC (dynamic) and a head-worn MIC
(condenser). The receivers for the lapel and handheld MIC are located in the main
sound equipment rack. These receivers are connected to the Mackie Mixer and the
Nexia CS unit through a MIC splitter. The receiver for the headset MIC is on top of the
counter sound equipment rack in the sound room and is connected directly to the
Mackie Mixer.
3. CD/Cassette Deck: A counter sound equipment rack to the right of the Mackie Mixer
includes a Tascam CD-A500 CD/Cassette player. Output from the player is connected to
the Mackie Mixer and the Nexia CS Sound Processor.
4. Video PC: A PC running Windows 7 is located under the counter with a VIA audio card. It
is connected to the Mackie Mixer and is used to play sound from a DVD, CD, video CD or
a computer file.
5. Direct-in Box: Currently the church has three (3) Direct-in Boxes. One (1) Pro Co AV-1A
and two (2) Behringer ULTRA-DI DI100 Boxes. These boxes convert unbalanced line-level
inputs to balanced XLR mic-level output (required by XLR input jacks). The Pro Co Directin Box is normally used is to connect a Laptop and the Behringer Direct-in Boxes to
connect a guitar pickup to an XLR input jack.
6. Blu-Ray Player: The Blu-ray player can be used to play Blu-ray discs, DVDs, and audio
CDs. It cannot play older video CDs (these can be played on the PC). The Blu-Ray Player
is normally not connected to the MUMC Sound System, but it can be connected to the
Mackie Mixer with the proper cables.
MUMC Sound System

Stands and Cables
Stands and Audio Cables are an important part of the sound system that are used to hold MICs,
place them were needed and connect them (and other instruments) to the sound system:
1. MIC Stands: The church currently has nine (9) MIC stands to hold stand mounted MICs.
Each stand consists of a base (the church has 3 weighted or 6 tripod), an extendable
tube and an optional top component (the church has 2 goosenecks or 2 booms). The top
components are threaded and can be attached to any MIC stand. A stand without a top
component is referred to as a ‘straight’ MIC stand and is used with condenser MICs
where the performer can and should be at least 12” from the MIC. A stand with a
gooseneck top component can be used for either condenser or dynamic MICs. A stand
with a boom top component is used where the MIC must be positioned at a distance
from the stand (ex. pianist’s solo MIC) and requires a tripod base. Either a dynamic or a
condenser MIC can be used with this top component, but they are normally used with a
dynamic MIC. A MIC Stand Clamp is also required to mount the MIC to the stand that is
designed to work with a specific MIC.
2. Audio Cables: Audio Cables are used to connect sound system capture components
(MICs, Direct-in Boxes and Wireless Receiver) to the sound system. There are multiple
types of cables that are used based on the components that are being connected:
a. XLR Cables: These cables have a female XLR and a male XLR jack. They are used
to connect MICs and Direct-in Boxes to the sound system. The church has one
(1) 7’ cable, nine (9) 25’ cables and two (2) 30’ cables of this type.
b. TRS Cables: These cables have a ¼” TRS jack at both ends. They are used to
connect instruments to Direct-in Boxes and the Wireless Receiver to the Mackie
Mixer. The church has one (1) 7’ cable and three (3) 30’ cables of this type.
c. XLR/TRS Cable: These cables have a male XLR jack and a ¼” TRS jack. They are
used to connect instruments to Direct-in boxes. The church has two (2) 15’
cables of this type.
d. Other: The church has numerous other types of cables that are dedicated to
connect various sound system components and are therefore not described in
this document.
Preprocessors and Splitters
After input the sound is preprocessed and split by the following components:
1. Dynamic Processor: A Behringer two-channel Composer Pro model MDX2200 audio
interactive dynamics processor is located in the main sound equipment rack. Inputs are
from the wireless lapel MIC and the handheld MIC. It is used to level the volume of the
sound from those inputs.
MUMC Sound System

2. MIC Splitter: A 4 channel ProSound MS42 MIC splitter is located in the main sound
equipment rack with two inputs from the Composer Pro. It is used to split the inputs
from the wireless lapel and handheld MICs for input to the Mackie Mixer and the Nexia
CS Sound Processor. Two channels are unused.
3. Audio Splitter/Amplifier: Two (2) analogue stereo splitters/amplifiers are located in the
back of the counter sound equipment rack. One is used to split the output from the
Cass/CD Player for input to the Mackie Mixer and the Nexia CS Sound Processor. The
other is used to split the ‘Line Out’ channel from the Nexia CS unit for input to the
Assisted Listening System (ALS), the Cassette Recorder and an RCA cable that can be
connected to the Sound PC. These units are not shown in the ‘Component Schematic’.
Mixers and Processors
After preprocessing and splitting, the sound is mixed (multiple sound sources are combined),
leveled (the volume of each source is adjusted) and then processed before being amplified. As
shown in the following diagram, there are two (2) different paths sound can take through the
MUMC Sound System. Please note that the sound from the Wireless Lapel MIC, the Wireless
Handheld MIC and the Cass/CD Player are split and follow both sound paths.
Mackie Mixer Sound Path
Some sound sources (XLR MIC input jacks in the Sanctuary, Video PC, Cass/CD Player, Wireless
Lapel Mic, Wireless Handheld Mic and the Wireless Headphone Mic) are mixed using the
Mackie Mixer and are then sent to the Nexia CS Sound Processor for processing prior to
amplification.
MUMC Sound System
Page | 7
Direct Digital Sound Processor Path
Some sound sources (XLR MIC input jacks in the Fellowship Hall, Wireless Lapel MIC, Wireless
Handheld MIC and the Cass/CD Player) are sent to the Nexia CS Sound Processor for mixing and
processing prior to amplification, bypassing the Mackie Mixer.
Sound Mixer and Processor Components
The following components mix and process sound prior to amplification:
1. Mackie Mixer
A Mackie Mixer model SR24-4 VLZPRO) is located on the counter in the sound room. The
Mackie Mixer is used to combine multiple sound inputs (mix) into multiple sound
outputs that can be heard in the church and recorded (see ‘Outputs’ below). All sound
inputs are connected to the Mackie Mixer except the 4 XLR MIC jacks located in the
Fellowship Hall. Outputs are to the Nexia CS sound processor, the Monitor A jacks in the
sanctuary, the Monitor B jacks in the sanctuary, the sound room speaker and the Sound
PC. A pair of headphones are connected to the mixer for monitoring. Reference
Appendix B for the steps to follow when adding a new MIC to this mixer.
2. Digital Sound Processor
The church has a Biamp Nexia CS Digital Sound Processor located in the main sound
equipment rack. It performs multiple functions including mixing, volume control, sound
leveling, equalization, splitting, feedback control, adding delays and sound leveling. The
unit also controls what sound is played where in the church (see ‘Outputs’) by
controlling what sound is routed to each amplifier channel (see ‘Amplifiers’) and direct
output (Line Out). It is hard wire connected to the Internet through a Wireless router
that sites on top of the main sound equipment rack. Two (2) remote panels and the
Sound PC are used to control the Nexia sound processor. A ‘Select 8’ Panel 2 is located
in the sound room to select sound presets and a ‘Volume 8’ Panel 3 is located in the
Fellowship Hall to control sound volumes to and from the Fellowship Hall. The Sound PC
is located under the Mackie Mixer with its monitor and keyboard immediately to the left
of the mixer. The daVinci program1 on the Sound PC can perform all the functions of the
Panels plus additional functions. See the ‘Sound Processing’ section of this paper for a
description of how the Nexia CS unit processes sound, the current presets that are
available and where that sound is sent.

Amplifiers
After the sound has been captured, mixed, split and/or processed it is amplified for playing on
the speakers located throughout the church (see ‘Outputs’). The church has the following
sound amplifiers located in the main sound equipment rack:
1. Crown CL1: A two channel sound amplifier with both channels sent to the Sanctuary
speakers (see ‘Outputs’), with channel 1 connected to the Sanctuary stage right
speakers and channel 2 to the stage left speakers. Input is from Nexia Output 1 (Main).

Outputs
Sound is output to the following locations in the church:
1. Speaker Zones: The church is divided into the following sound ‘zones’ with speakers
permanently mounted in each. All of the zone speakers are connected to the amplifiers
and controlled by the Nexia CS sound processor.
a. Sanctuary: Two speakers mounted on the ceiling at the front of the sanctuary
stage.
b. Fellowship Hall: Fifteen (15) ceiling speakers mounted evenly in the Fellowship
Hall ceiling.
c. Crying Room: A single ceiling speaker mounted in the center of the Crying Room
ceiling. A volume control for this speaker is located next to the door in the
Crying Room.
d. Sunday School Room: A single ceiling speaker mounted in the ceiling at the front
of the Sunday School Room. A volume control for this speaker is located next to
the front door to the Sunday School Room.
e. Kitchen: A single ceiling speaker is mounted in the ceiling of the Kitchen. A
volume control for this speaker is located next to the phone in the Kitchen.
f. External Speaker: A single speaker is mounted above the front door to the
church.
2. Movable Speakers: The church currently has two movable, unamplified floor speakers
that are used as stage monitors. One (1) XLR amplified speaker jack is located in the
Sanctuary stage left and one (1) stage right for connecting stage monitors (labeled
Monitor A).

3. Pianist Monitor: An amplified speaker is set next to the pianist and is connected to the
Monitor B jack in the Sanctuary stage left. A second Monitor B jack is located in the
Sanctuary stage right. The Pianist Monitor can also be used as a remote mixer in the
MUMC Portable Sound System. Please reference the ‘MUMC Portable Sound System’
document for additional information on how the unit can be used in that sound system.
4. Sound PC: A mono line out is connected to the Sound PC from the Mackie Mixer (Aux
Send Master 4) for recording on the Sound PC (Audacity is used as the Audio Editor).
5. Sound Room Speaker: An amplified speaker is located on top of the counter sound
equipment rack and is connected to the Mackie Mixer R-Control Room Out jack.
The following three (3) output locations are connect to a terminal strip in the Main Sound
Equipment Rack. The input to this terminal strip is from the Nexia CS Sound Processor
Output Channel 6 (Line Out).
6. Cassette Recorder: A mono line out is connected from the Nexia CS Sound Processor
(Output Channel 6: Line Out) to an Analogue Splitter/Amplifier and then to a Tascam
102 MKII cassette recorder located in the counter equipment rack for recording on a
cassette tape.
7. Assisted Listening System (ALS): The church currently has an ‘assisted audio’ sender
unit and six (6) receiver units. The sender unit is located on the top of the counter
equipment rack in the sound room and receives mono input from an Analogue
Splitter/Amplifier that is connected to the Nexia CS Sound Processor (Output Channel 6:
Line Out).
8. Church A/V Network: A line from the Nexia sound processor (Output Channel 6: Line
Out) is sent to a UHF Modulator and combined with the church video signal and output
on a coaxial cable into the church’s A/V network.
Each of the TV Monitors (three in the sanctuary and one in the Fellowship Hall) has its own
set of speakers. They receive sound through the HDMI inputs on each monitor and are
currently not directly connected to the MUMC Sound System. Please reference the ‘MUMC
Video System’ document for a description of the monitors and using them to play sound.
MUMC Sound System

Power
Power is supplied to components of the sound system in the following ways:
1. Phantom Power: Phantom power is a 48 volt DC current sent to the XLR MIC jacks in the
sanctuary (from the Mackie Mixer) and the Fellowship Hall (from the Nexia CS sound
processor). The ‘phantom power’ in the XLR jacks is part of the integrated power system
(see below). Wired microphones and the Direct-in Box receive power through the
‘phantom power’ in the XLR jacks. Note: Condenser microphones and the direct-in box
require a power source either through ‘phantom power’ or batteries. Dynamic
microphones do not require power, but most dynamic microphones are not harmed if
‘phantom power’ is present.
2. AA Rechargeable Batteries: The wireless microphone’s sending units receive power
from rechargeable ‘AA’ batteries in each unit that must be removed and recharged
when required. The receivers for the wireless MICs are part of the integrated power
system (see below).
3. Internal Rechargeable Batteries: The Assisted Hearing receiver units are powered by
internal rechargeable batteries or AA non-rechargeable batteries. There is a switch
inside each receiving unit to set the battery type. DO NOT try to recharge a unit that has
non-rechargeable batteries. Rechargeable batteries must be recharged between uses by
being plugged into the recharging station. The Assisted Listening System (ALS) send unit
is part of the integrated power system (see below).
4. Direct Power: The Sound PC and the Blu-ray Player receive power directly from a wall
outlet. As such each component must be plugged in (if unplugged) and turned on
manually.
5. Integrated Power System: All other sound system components receive power through
an integrated power system. When the counter sound equipment rack main power
switch is turned on power is sent to the sound components in the sound room (Mackie
Mixer, Cassette/CD Player, Cassette Recorder, Wireless Headset MIC send unit and
Assisted Listening send unit) and a signal is sent to a Furman power unit in main sound
equipment rack. That unit then turns on all other sound components in the proper
sequence and with the proper delays (Composer Pro, MIC splitter, UHF Modulator,
Nexia CS Sound Processor and amplifiers).
MUMC Sound System

Sound PC
A PC running Windows 8.1 is located under the Mackie Mixer with the Monitor/Keyboard for
the PC on the sound room immediately to the left of the Mackie Mixer. This is the ‘Sound PC’.
There is also a PC running Windows 7 located behind the door in the middle of the counter with
two monitors and a keyboard located above the PC. This is NOT the Sound PC, but instead the
MUMC ‘Video PC’ that is used to control the MUMC Video System. Sound output from the
‘Video PC’ is connected to the Mackie Mixer stereo channel 21-22 and sound from this PC can
be played through the MUMC Sound System, but it is NOT the Sound PC. Please reference the
‘MUMC Video System’ document for a description of the MUMC ‘Video PC’.
The ‘Sound PC’ is connected through a Mono line to the output from the Mackie Mixer through
the Aux Send Master 4 output and to the Nexia CS Sound Processor through a wireless Internet
connection. The ‘Sound PC’ performs the following functions:
Sound Recording and Editing
The Aux Send Master 4 mono output from the Mackie Mixer can be recorded and then edited
on this PC using any sound capture/editing software (currently the church uses Audacity for
capturing and editing sound). A headset is connected to the PC for monitoring the sound and
for use when editing.
Sound Monitoring and Control
Monitoring and control of selected sound levels and presets on the Nexia CS Sound Processor
can be done from this PC either before, after or during a performance. This is done through the
‘daVinci’ program1 on the Sound PC. Open the program by double-clicking on the appropriate
icon and it will download a ‘parameter file’ from the Nexia CS Sound Processor, connect to the
Nexia unit over the Internet and then open a window with various meters and controls. You can
then use this window to monitor sound levels and change presets in the Nexia CS Sound
Processor. Reference the ‘Appendix C: daVinci Program’ for a complete description of daVinci
program control surface.
Nexia CS Programming
This PC can also be used to reprogram the Nexia CS Sound Processor. This should only be done
by a qualified sound engineer and the instructions to perform that function are not included in
this document.

Sound Capture
The MUMC sound system can capture both live and prerecorded sound. It must be noted that
the MUMC sound system is a mono sound system. Although the mixer has balancing controls
on all channels and does accept stereo inputs on two channels, all the channels are combined
into a single channel prior to output from the system. Therefore all outputs from the system
are mono including the speaker zones and the recorders (the Sound PC and the Cassette
Recorder). As a result all pan/balance controls are normally set at unity (centered). Changing
the pan control on either of the stereo inputs (channels 21-22 or 23-24) can result in muting
one of the stereo channels.
Capturing Live Sound
Live sound is captured through eighteen (18) XLR MIC input jacks and three (3) wireless
microphones.
XLR MIC Input Jacks
Fourteen (14) of XLR jacks are located on the sanctuary stage (6 stage right, 2 stage center and
6 stage left) and are connected to the Mackie Mixer (channels 1 through 14). Four (4) XLR jacks
are located in the Fellowship Hall in a wall plate and are connected directly to the Nexia CS
sound processor. Reference Appendix B for the steps to follow when adding a new MIC or
moving an existing MIC to a different XLR jack in the Sanctuary. The following units can be
connected to the XLR jacks:
1. Condenser Microphones
The church has four (4) stand mounted
condenser microphones and a condenser
microphone on the podium. The polar
pattern for all four is cardioid (see diagram)
and all four can pick-up sound from up 20 ft.
away from the MIC. These microphones are
excellent for voices, groups and instruments
(especially acoustic guitars).
Cardioid Polar Pattern
Because of the range of these microphones care should be taken that they are not
placed in a location where the main speakers or the stage monitors are within their pickup pattern, otherwise you will create a feedback loop. This especially applies to the
Fellowship Hall since the speakers are located in the ceiling facing down. They are also
sensitive to rough handling.
MUMC Sound System
Page | 14
Normally one condenser MIC is plugged into channel 4 and is located Sanctuary stage
right facing the pews to pick-up the audience. Two condenser MICs are plugged into
channels 7 and 12 Sanctuary stage left and are on stands next to the piano. These two
are used for the choir, voice solos and/or instruments. The fourth stand mounted
condenser MIC is used to capture the piano and is plugged into channel 11 stage left.
2. Dynamic Microphones
The church has five (5) dynamic microphones. The polar pattern for all five is cardioid
(same as condenser MICs, see diagram) and they are sensitive to the distance to the
sound source. Each MIC also has an on/off switch on the MIC that can be used by the
performer. They normally used solo vocals.
Because of their sensitivity to distance they are called solo MICs and are less likely to
create feedback, but care should still be taken when placing them. An experienced
performer will also use this sensitivity to distance to vary the sound level during the
performance by moving closer to and away from the MIC. You should provide a gentle
warning to inexperienced performers to turn the MIC on and to maintain a consistent
distance from the MIC during the performance. These microphones are also very
rugged.
Normally one Solo MIC is connected to channel 8 and is placed on a stand next to the
piano for use by the pianist. The other four (4) dynamic MICs are stored in the sound
room and can be connected to any XLR jack in the Sanctuary or the Fellowship Hall.
3. Direct-in Boxes
Currently the church has three (3) Direct-in Boxes; one (1) Pro Co AV-1A and two (2)
Behringer ULTRA-DI DI100 Boxes. The Pro Co AV-1A converts unbalanced line-level
inputs from 2 RCA jacks, a 3.5mm stereo mini jack or a 1/4 inch stereo phone jack to
balanced XLR mic-level output (required by XLR input jacks). The two (2) Behringer
ULTRA-DI DI100 Boxes convert unbalanced line-level input from an XLR jack or a 1/4 inch
TRS jack to balanced XLR mic-level output. Both can be used to connect unbalanced linelevel input (example acoustic guitar internal pickups) to any of the XLR MIC input jacks in
the Sanctuary or the Fellowship Hall. They can also accept speaker level input from an
electric guitar amplifier through the 1/4 inch stereo phone jack. The Pro Co AV-1A can
also accept input from a laptop PC through stereo RCA jacks. One Direct-In Box normally
sites on the floor behind the piano, is used to connect the internal pickups of the
pianist’s acoustic guitar and is connected to channel 10. The other two Direct-In Boxes
are located in a sound room drawer.

Wireless Microphones
The church has the following wireless microphones:
1. Headset MIC
This unit is a Samson Airline 77 Headset with a separate receiver unit. The headset is
fully contained including a unidirectional condenser microphone (cardioid polar pattern,
see diagram) and transmitter with no belt-pack or cable. The transmitter pack has a
mute button, power switch and low battery LED. It is for those performers who do not
want to use a belt-pack transmitter or the ear-worn microphone of the lapel MIC. It also
provides an additional hands free wireless MIC when required. The receiver unit sits on
top of the counter sound equipment rack and is connected to channel 15 through the
line-in jack. Due to the range of the MIC feedback can be a problem with this unit.
2. Wireless Lapel MIC
Although called a ‘lapel’ MIC throughout
the sound system documentation, this is
actually a ear-worn omnidirectional (see
diagram) condenser microphone that
hooks over either ear. It is cable
connected to an Audio Technica belt-pack
transmitter (can also be inserted in a
pocket) that includes an on/off button,
mute button and an LED that displays
battery level and frequency usage. The
Omnidirectional Polar Pattern
receiver unit is in the main equipment
rack. It is connected through a MIC Splitter to channel 17 on Mixer and the Nexia CS
unit’s input 4. The limited range of the MIC limits feedback.
3. Wireless Handheld MIC
This is a handheld dynamic MIC with a cardioid polar pattern (see diagram) with an
internal wireless transmitter. As with the wired dynamic MICs, this MIC has an on/off
switch located in the base and is sensitive to the distance between the MIC and the
performer. It also has an LED that shows battery level and frequency usage. The
receiver unit is located in the main equipment rack. It is connected through a MIC
Splitter to channel 18 on Mixer and the Nexia CS unit’s input 5. The limited range of the
MIC limits feedback.

Capturing Prerecorded Sound
Prerecorded sound can be captured and played through the sound system from the following
devices:
1. Video PC
The Video PC speaker output is connected to stereo channel 21-22 on the Mackie Mixer
through the line inputs for that channel. Any sound generated on the Video PC can be
transmitted to the Mackie Mixer including CDs, DVDs, MP3 files and video files. There
are no other speakers connected to the Video PC and when headphones are plugged
into the Video PC the output to the Mackie Mixer may be disabled. The output from the
Video PC can also be changed through the Sound Control Panel to HDMI for playing on
the monitors located in the Sanctuary.
2. CD/Cassette Deck
The CD/Cassette deck is located in the counter equipment rack. It is connected to
stereo channel 23-24 on the Mackie Mixer through the line inputs for that channel and
to the Nexia CS sound processor (Nexia CS unit’s input 3).
3. Blu-ray Player
The Blu-ray Player sites on the sound room counter or is in the Fellowship Hall and is
normally not connected to the MUMC Sound System. You can play the Blu-ray sound
through the Monitors by connecting the HDMI output from the Blu-Ray player to the
‘input’ jack on the HDMI ‘splitter’. Please reference the ‘MUMC Video Manual’ for the
step-by-step instructions for using the Blu-Ray Player with the MUMC Video System. You
can also play sound from the Blu-Ray Player through the MUMC Sound System by
running an RCA extension cable from the RCA jacks on the Blu-ray Player to stereo
channel 21-22 on the Mackie Mixer (replaces the current Video PC connection). We
currently do not have the cable or the required adapters for this connection.

Sound Processing
For the purposes of this section of the document we are using the broadest definition of the
term ‘sound processing’ including but not limited to preprocessing, splitting, mixing, routing,
leveling, adding delays, equalizing and adding audio effects. In essence we are including
anything that modifies the sound after it is captured but before it is output for amplification or
recording.
Overview
Before the sound that has been captured can be ‘played’ in the church it must be processed.
This ensures that each input can be heard at the proper level (the piano does not overpower
the singer), that echoes are eliminated, that feedback loops are stopped (that annoying high
pitched squeak), that the output is rich in tone, that the sound is not too loud or soft, that the
sound can be heard in the proper location(s) in the church (or not heard) and finally that the
sound is tailored for the location where it is being heard. Without sound processing a pleasing
sound (be it inspiring music or a thought provoking sermon) can quickly become annoying
noise.
Sound that has been captured is prepared for output (processed) by the following sound
system components:
1. Dynamic Processor
A Behringer two-channel Composer Pro model MDX2200 audio interactive dynamics
processor is located in the main sound equipment rack and performs a very specific
function for two input sources. That function is to dynamically modify the volume level
of the sound captured by the wireless lapel and handheld microphones by decreasing
the volume of sound that is too loud and increasing the volume of sound that is too soft.
When this is done, by how much and how quickly is controlled by a series of knobs on
the front of the unit. This unit has been setup by a qualified sound engineer and should
not be changed without first contacting a qualified sound engineer. Fiddler beware!
2. MIC Splitter
A 4 channel ProSound MS42 MIC splitter is located in the main sound equipment rack
and accepts the two outputs from the Dynamic Processor (wireless lapel and handheld
MICS). Its function is to take each input and split it into two outputs while matching the
signal level of each output to the input. For the wireless lapel MIC one output is sent to
the Mackie Mixer (channel 17) and the other to the Nexia CS sound processor (Nexia
Input 4). For the wireless handheld MIC one output is sent to the Mackie Mixer
(channel 18) and the other to the Nexia CS sound processor (Nexia Input 5). Two
channels are unused.
MUMC Sound System
Page | 18
3. Audio Splitter/Amplifier
An analogue audio splitter/amplifier is located in the back of the counter sound
equipment rack. It takes a single stereo input, amplifies it and then sends it to up to 6
outputs. It amplifies the output from the Cass/CD Player and then sends it to the Mackie
Mixer (stereo channel 23-24) and after combining using an RCA cable connector to the
Nexia CS unit (Nexia Input 3). Four (4) outputs are unused.
4. Mackie Mixer
A Mackie Mixer model SR24-4 VLZPRO is located in the sound room and is run by a
sound operator who manipulates knobs, buttons and sliders to select, combine, split,
modify and finally output the sound that has been captured until the operator achieves
the desired result. The Mackie Mixer is both limited by and greatly benefits from the
experience, the knowledge and the ‘ear’ of the operator. It is best suited to a dynamic
environment where the performers, input devices, output requirements and even the
overall performance environment are continually (even dynamically) changing and
cannot be accurately forecast in advance.
The Mackie Mixer is used to mix and process all live sound captured in the Sanctuary
along with prerecorded sound from the Video PC and the CD/Cassette Player (reference
Appendix B for the steps to follow when adding or moving a Sanctuary MIC).
5. Nexia CS Sound Processor
The Nexia CS Sound Processor is located in the main equipment rack and can perform all
of the functions performed by the Mackie Mixer plus a few more. Whereas the Mackie
Mixer is controlled by an operator, the Nexia CS unit is controlled by a program written
by a qualified sound engineer. Its primary purpose is to control what sound is played
where in the church. It also processes the sound based on the location where it is played
to maximize the quality of the sound in that location.
The Nexia CS program has been written to accept control input that selects preprogrammed options and/or controls selected functions from the following locations in
the church (see the ‘Nexia CS Sound Processor’ section of this document for a more
complete description of the program, the pre-programmed options that are available
and the functions that can be controlled):
o Select 8 Panel2
This panel is located in the sound room and is used to select pre-programmed
options (Presets) that affect sound output.
o Volume 8 Panel3
This panel is located in the Fellowship Hall and is used to control preprogrammed options that affect sound volume input or output levels in the
Fellowship Hall.
MUMC Sound System
Page | 19
o Sound PC
The Sound PC is located under the Mackie Mixer in the sound room with the
monitor and keyboard for the PC located on the counter directly to the left of
the Mackie Mixer. The daVinci program1 installed on the Sound PC allows for the
monitoring and control of selected functions in the Nexia CS Sound Processor.
Mackie Mixer
Mackie Mixer
A Mackie Mixer model SR24-4 VLZPRO is located in the sound room and is run by a sound
operator. It has a large number of knobs, buttons and sliders that are used to select, combine,
split, modify and finally output the sound that has been captured. The operator manipulates
these controls during a live performance to control how different sound inputs are combined
(mixed) and the quality of the sound that is output. Although intimidating at first, acceptable
results can be obtained with minimal training. With experience, a trained operator can produce
amazing results. In addition the unit has capabilities and functions that are not currently being
utilized by the church.
MUMC Sound System
Page | 20
The purpose of this section is to provide an overview of the basic functions of the Mackie
Mixer, how those functions are controlled and how the church currently uses those functions. It
is not intended as a training manual or a substitute for the unit’s user manual. ‘Appendix D:
Sound System Setup’ defines the ‘default’ settings for the mixer for a typical Sunday Service.
This Appendix can be used as a starting point to fine tune the mix or to reset the mixer to a
known state if it is not performing as expected.
Mixer Basic Functions
The Mackie Mixer performs the following basic functions:
1. Inputs
The mixer can accept and control the level of input from up to 22 different sound
sources. The first 20 (channels 1-20) accept mono input from either a MIC or line level
input. The last two (channels 21-22 and 23-24) accept line level input from stereo
sources. Reference ‘Appendix B: Adding or Moving a Sanctuary MIC’ for the steps to
follow when adding a new MIC or moving a MIC to a different channel.
2. Mixing
Each input channel can be added (mixed) at the desired level on up to eleven (11)
different output channels. A mute function will remove the channel from all outputs
(except solo, see below). The level of each output channel can be controlled separately.
The outputs include the main mix, six (6) auxiliary channels and four (4) sub channels. In
addition the four sub channels can be routed to the main mix. All output channels are
mono except for the main channel, which can be either stereo or mono (the church only
uses the mono output).
3. Internal Effects Processing
Each input channel can be equalized by boosting or cutting low, mid and high level
frequencies. In addition an ‘AIR’ function is provided for each sub channel that boosts
the signal up to 10 dB centered at 16K Hz. This adds a crystalline effect allowing the sub
channel to stand out in the main mix.
4. External Effects Processing
External effects processors (compressors, equalizers, harmonizers, etc.) can be
connected to any input channel, aux channel, sub channel or the main mix. The signal is
sent to the effects processor and then returned to the mixer for addition to the main
mix. Effects can be added serially or in parallel with the original signal. The church does
not currently have any external effects processors so this function is not used.
MUMC Sound System
Page | 21
5. Solo
Each input channel, aux channel or sub channel can be ‘soloed’. When a channel is
‘soloed’ its signal is sent to the sound room speaker (site on the top of the counter
equipment rack and is normally off), the headphones and the meters. The ‘mute’
function on the input channels will not mute the solo channel if the solo mode is set to
PFL (Pre-Fader Listen, see Solo Section). This allows the operator to monitor or ‘preview’
an input channel for level and sound quality before adding it to the main mix. If nothing
is ‘soloed’ the main mix is sent to the sound room speaker, the headphones and the
meters.
6. Talk Back
This function allows the signal from a sound room microphone to be routed to the main
mix and/or Aux channels 1 & 2. This allows the operator to address the audience and/or
the performers. The church does not have a microphone in the sound room so this
function is not used.
7. Pan
Each input and sub channel can be ‘panned’. For mono channels this moves the signal
from the left to the right of the stereo output channel allowing the operator to ‘place’
the input within the main mix. On the stereo inputs it operates as a balance control,
attenuating one side or the other. When an input is sent to the sub channels (1-2 or 34) the pan control for the input channel controls which sub channel receives what
portion of the signal. As an example if the pan knob for an input is set full left then sub
channels 1 and 3 receive that signal. When the pan knob is set full right then sub
channels 2 and 4 receive that signal. In addition the pan function uses ‘constant
loudness’ which ensures that the output remains at the same level regardless of where
the pan is set. Since the church only uses mono outputs, the input channel pan knobs
are only used to control which sub channel receives an input signal. Unless you have
assigned an input channel to a sub channel, the pan knob for the input channel should
be left centered. The pan knobs for the sub channels should always be left centered.
8. Tape In
The ‘tape in’ function allows the operator to replace the output to the
headphones/sound room speaker and/or the main mix with input from the ‘tape in’
jacks. Since nothing is currently connected to the ‘tape in’ jacks, engaging the ‘Tape
Return to Phones’ or ‘Tape Return to Main Mix’ button will have the effect of muting
the headphones or the main mix. If you are not hearing any sound in the Sanctuary
and/or the headphones these are the first buttons you should check.
MUMC Sound System
Page | 22
9. Output
Outputs from the Mackie Mixer are connected to:
o ‘Main’ input on the Nexia CS unit (Nexia Input 1) from the Mono Main Out.
o ‘Monitor A’ input on the Nexia CS unit (Nexia Input 2) from Aux Send 1 Out.
o ‘Monitor B’ jacks in the Sanctuary from Aux Send 2 Out.
o ‘Line In’ on the Sound PC from Aux Send 4 Out.
o Headphones from ‘Phones 1’.
o Sound room speaker from ‘R-Control Room Out’.
The Main Outs (TRS and XLR), Sub Outs, Aux Send 3 Out, Aux Send 5 Out, Aux Send 6
Out and Tape Out on the Mackie Mixer are currently not used by the church.
Mixer Controls
The following are the controls that are used to manage the mixer’s functions. If the church
does not use a function, then the controls for that function are listed but they are not
described. The mixer’s controls are divided into two areas.
Channel Strip Controls
Master Controls

Channel Strip Controls: This area includes the controls for the mixer’s inputs and is
grouped by input channel.

Master Controls: This section includes controls for the aux channels, sub channels,
stereo aux returns, solo, talk back, tape return, and the master fader. It also includes a
sound meter.
MUMC Sound System
Page | 23
Channel Strip Controls
Each input channel has the following controls:
1. Trim Knob
This knob adjusts the sensitivity of the MIC or line
input connected to that channel. On the mono
channels (1 – 20) it boosts the signal from a MIC from
0 to +60dB and for a line input from minus 15dB to
plus 45dB. For a stereo channel (21-22 and 23 -24)
the input is adjusted from -20dB to +20dB.
2. Aux Send Section
These knobs (1 - 6) tap a portion of the signal and
send it to the aux channel associated with that knob.
Aux channel 1 and 2 are always pre-fader (the signal is
taped prior to the channel fader for this channel but
after the Trim, mute and EQ settings) and post-fader
for aux channels 5 and 6 (signal is sent after channel
fader and after the Trim, mute and EQ settings).
When the ‘Pre’ button is engaged (down) aux
channels 3 and 4 are pre-fader and when disengaged
(up) post-fader.
3. EQ Section
These four knobs provide equalization control for the
input channel (cutting or boosting the signal within a
defined frequency range). The first knob is centered
at 12k Hz. The last knob is centered at 80Hz. For a
mono channel the 2nd knob sets the level and the 3rd
knob defines the target frequency (from 100Hz to 8k
Hz). On mono channels there is also a low cut button
that cuts bass frequencies below 75Hz at 18dB per
octave to reduce stage rumble and MIC handling
clunks. On stereo channels the 2nd knob is Low Mid
centered at 800Hz and the 3rd knob is Hi Mid centered
at 3K Hz.
MUMC Sound System
Page | 24
4. Pan Knob
For mono channels this knob moves the signal from the left to the right of the stereo
output channel allowing the operator to ‘place’ the input within the main mix. On the
stereo inputs it operates as a balance control, attenuating one side or the other.
5. OL and -20db LEDs
The OL LED flashes red if the signal is too ‘hot’ causing an overload. The -20db LED will
flicker when the input level is above -20db (also known as a ‘signal present indicator’).
6. Mute Button
This button severs the input signal from all subsequent outputs and the ‘Mute/Solo’ LED
will glow red. A ‘muted’ channel can still be soloed if the Solo Mode is set to PFL (PreFader Listen, see Solo Section under Master Controls).
7. Solo Button
When this button is engaged the signal for this input channel is sent to the sound room
speaker, headphones and meters. When engaged the ‘Mute/Solo’ LED will flash red. If
the ‘mute’ button is also engaged the LED will pulsate red. A ‘muted’ channel can still be
soloed if the Solo Mode is set to PFL (Pre-Fader Listen, see Solo Section under Master
Controls).
8. 1-2, 3-4 and L-R Buttons
When engaged these buttons route the final signal for this input channel to the
appropriate sub channel pair (1-2 or 3-4) and/or the main mix (L-R). Typically only one
of these buttons will be engaged. To route the signal to sub channel 1 or 3 turn the pan
knob fully to the left. To route the signal to sub channel 2 or 4 turn the pan knob fully to
the right. Otherwise leave the pan knob at unity (centered). Channel Fader: This slider
controls the sound level sent to the post-fader output channels for this input channel.
The sub channels and main mix are post-fader. Aux 1 and Aux 2 are pre-fader (not
affected by this slider). Aux 5 and 6 are post-fader (they are affected by this slider). Aux
3 and 4 are either pre or post fader (see Aux Send Section). The solo is either pre or post
fader (see Solo Section).
MUMC Sound System
Page | 25
Master Controls
These controls include:
1. Aux Send Masters Section
The Aux Send Masters are a series of
knobs that control the output level for
each aux channel (1-6). Next to each
knob is a solo button that will send that
aux channel to the sound room speaker,
headphones and meter when engaged.
2. Aux Stereo Returns Section
This section contains a set of controls for
the aux stereo returns and tape return
volume. The church does not use any of
these controls and they should be set at
unity or off.
3. Sub Channel Section
Each sub channel has a series of controls
including AIR (boosts high frequency),
Solo (routes channel signal to control
room speakers, headphones and meter),
Pan (not used, leave at unity), L/R Assign
(routes sub channel signal to main mix)
and a sub channel fader to control the
volume of this sub channel.
4. Meter Section
This section does not contain any
controls, but instead a series of LEDs.
The Power LED will light green when the
mixer is receiving power. The ‘Rude Solo
Light’ LED will flash red when any solo
button is engaged. This tells the
operator that the meters are reflecting the solo inputs and not the main mix. The
meter is made up of two columns of thirteen (13) LEDs each. Since the church’s sound
system is mono, these columns should always match. Thresholds for the meter range
from -40dB to ‘Clip’. At +10dB the LEDs change to yellow and red at +20dB. The normal
range of the main mix for the church is -15dB to 0dB.
MUMC Sound System
Page | 26
5. Solo Section
The level knob in this section controls the level of output from all soloed channels that is
sent to the sound room speaker and the headphones. It does not affect the meters.
When the mode button is disengaged all soloed channels are input before the channel
fader for each soloed channel (PFL – pre-fader listen). This is the normal setting for live
sound applications. When solo mode is engaged the signals are tapped after the channel
fader (AFL –after fader listen). The AUX LED will flash red if any aux channel has been
soloed and the SUB LED will flash red if any sub channel has been soloed.
6. Talkback Section
This section controls the sound room MIC input volume and where it is output. The
church does not have a MIC in the sound room and all these controls should be off.
7. Main Mix Section
The ‘Phones / C-R Level’ knob controls the volume of the headphones and the sound
room speaker. It is normally set very low to avoid hearing loss. The sound room speaker
also has a volume control on the speaker.
Since nothing is connected to the Tape In jacks, engaging the ‘Tape Return to Phones’
will mute the headphones and the sound room speaker. Engaging the ‘Tape Return to
Main Mix’ will mute the main mix output.
The Main Mix slider controls the volume of the main mix output from the mixer. This
impacts the volume of every speaker in the church, the cassette recorder and the sound
sent to the A/V system. It does not impact the sound sent to the Monitor A jack (Aux
Send Master 1), the Monitor B jack (Aux Send Master 2) or the Sound PC (Aux Send
Master 4).
The Fellowship Hall can be configured to receive sound from the mixer by setting the
Nexia CS to the proper preset (see the section ‘Sound Processing – Nexia CS Presets’ for
a description of the presets) and in this mode the sound level in the Fellowship Hall is
impacted by the main mix slider. The Nexia CS Sound Processor can also be set so that
the Fellowship Hall receives sound directly from the Nexia CS unit, by-passing the mixer
completely. In these modes the main mix slider, in fact any mixer setting, has no impact
on the Fellowship Hall. Reference the ‘Nexia CS Sound Processor’ section of this
document for a more complete description of the different presets available.
MUMC Sound System
Page | 27
Nexia CS Sound Processor
The Nexia CS Sound Processor is located in the main equipment rack and is used to control
what sound is played where in the church. It also processes the sound based on the location
where it is played to maximize the quality of the sound in that location.
Nexia CS Inputs
The Nexia CS input block accepts up to 10 inputs and then coverts them to digital signals. An
RMS Meter is connected to the Input Block for the monitoring of all inputs. The inputs are
currently connected to the following sound sources:

Program Overview
The Nexia CS program is divided into the following four (4) sections:
Input Controls
This section of the program prepares the sound for level control and routing. It includes
Comp/Limiters for the Main Input and Monitor Input to reduce transient peaks. The Cass/CD
input is split with outputs sent to the external speaker and Fellowship Hall level control. High
Pass Filters are used to ‘tune’ the input that will be sent directly to the Fellowship Hall.
Please note that the CD/Cass Player, Wireless Lapel and Wireless Handheld have been split with
output sent directly to the Mackie Mixer and to the Nexia Processor. This allows the input from
these devices to be added to the Main Mix controlled by the Mackie Mixer and/or to be sent
directly to each sound zone under the control of the Nexia Sound Processor.
MUMC Sound System
Page | 28
Internal Sound Level Controls
This section of the program controls the level of each input after they have been converted to
digital signals through the following level controls:
1. Main Level Control
This level control is normally not changed, you change the levels of the Main Mix by
adjusting the Master Volume on the Mackie Mixer. An RMS meter is provided to
monitor the output.
2. Monitor Level Control
This level control is normally not changed, you change the levels of the Monitor by
adjusting the Aux Send 1 Out on the Mackie Mixer. An RMS meter is provided to
monitor the output.
3. Cass/CD Level Control
This level control is normally not changed and only applies to the Cass/CD channel that
is directly routed through the Nexia CS Sound Processor to the External Speaker. It does
not apply to the level of the Cass/CD Player in the main mix (that is controlled by the
Mackie Mixer) or the Fellowship Hall Mix (that is controlled by the Fellowship Hall Level
Control, see below). You change the levels of the Cass/CD Player on the External
Speaker by changing the output level for the External Speaker (see Output Channels). An
RMS meter is provided to monitor the output.
4. Fellowship Hall Level Control
This level control sets the sound levels of each of the inputs to the Fellowship Hall Mix
(see below). This includes the Cass/CD Player, the Wireless Lapel Mic, the Wireless
Handheld Mic and the Mics connected to the four (4) XLR input jacks in the Fellowship
Hall. It only applies to the level of sound in the Fellowship Hall Mix and does not impact
the level of sound from the Cass/CD Player, the wireless Lapel Mic or the Wireless
Handheld Mic in the Main Mix or when the Cass/CD Player is routed directly to the
External Speaker. This Level Control can be controlled through the Nexia CS Volume 8
control panel in the Fellowship Hall. An RMS meter is provided to monitor the output
level of each source.
Routing Controls
The routing section of the program distributes and balances the input channels for distribution
to the Output Channels (see below) through the following three (3) mixers:
1. Fellowship Hall Standard Mixer
This mixer combines the inputs from the Cass/CD Player, Wireless Lapel Mic, Wireless
Handheld Mic, and the four (4) XLR MIC input jacks in the Fellowship Hall input a single
output. A Comp/Limiter is then applied to the output to reduce transient peaks and
MUMC Sound System

create the Fellowship Hall Mix. An RMS meter allows monitoring of the level of the
Fellowship Hall Mix.
2. External Speaker Standard Mixer
This mixer selects which of three (3) sources (Main Mix, Cass/CD Player or Fellowship
Hall Mix) will be played on the External Speaker. The setting of this Mixer is controlled
by programmed presets (see Nexia CS Presets).
3. Main Matrix Mixer
This mixer determines which of three (3) sources (Main Mix, Monitor Input and
Fellowship Hall Mix) will combined and routed to five (5) Output Channels (Main,
Monitor, Fellowship Hall, Auxiliary System and Line Out, see below). The setting of this
Mixer is controlled by programmed presets (see Nexia CS Presets).
Output Controls
Based on the settings of the Mixers, sound is routed to the following Output Channels:

Each of the controls in the Nexia CS program has multiple settings that determine how sound is
processed by the Nexia CS unit. These settings are determined by a sound engineer when the
program is written, but some of the settings can be changed or modified by an operator either
before or during a performance. They can be changed from the Select 8 Panel2 in the sound
room, the Volume 8 Panel3 in the Fellowship Hall or through the daVinci program1 on the Sound
PC. The daVinci program includes all the capabilities available from the Panels, additional
functions not available from the Panels and sound level meters. The settings that can be
changed where determined by the sound engineer when the program was written in the
following ways:

Presets
‘Presets’ are groups of related settings. When a ‘preset’ is selected (becomes active) all the
settings related to that ‘preset’ are changed. Presets can be selected (activated) on the Select 8
Panel2 by turning the knob on the panel until the light next to the desired ‘preset’ is lite and
then pressing the knob ‘in’ to select (activate) that ‘preset’. The daVinci program has buttons
for each available ‘preset’ with a light next to each button showing which ‘preset’ is selected
(active). Clicking on a button will select (activate) that ‘preset’. The daVinci program 1 also has
additional presets that are not available from the Select 8 Panel2 (reference Appendix C for a
description of the daVinci program).
‘Presets’ belong to ‘preset groups’. Within a ‘preset group’ the program has been written so
that only one preset can be selected (active) within the group. Selected (activating) a preset in
a group will turn off (deactivate) all other ‘presets’ in that group. The following ‘presets’ are
available:

Routing Controls
Mixers control how sound is routed through the Nexia CS Sound Processor and are impacted by the
‘presets’ (see above). The Main Mixer is available on the ‘Main Control’ screen 1 and the Fellowship Hall
Mixer is available on the ‘Fellowship Hall Control’ screen1 of the daVinci program.
Volume Level Controls
Volume Level Controls provide the ability to change the sound level and/or mute a specific channel. The
channel can be an input channel, an output channel or a channel (bus or MID) within the Nexia CS
program. Each volume level control also has a meter associated with it to monitor the current sound
levels being processed by the Nexia CS unit. The Channel Input and Outputs meters are Peak Meters that
show the actual sound levels. They are used to ensure that sound is not too loud or too soft when input
or output. The MID and Fellowship Hall Input meters are RMS meters that show an average level that is
closer to how humans would perceive the sound. They are used to balance or mix the sound levels.
The daVinci program on the sound PC provides access to all the MID, Fellowship Hall Mixer Input and
Output level controls in the Nexia CS program. It does not provide access to the initial input levels
before the sound is digitized. These levels are tuned to the sound generated by each input source and
should only be changed by a qualified sound engineer. The daVinci program includes mute buttons and
meters for all initial input, MID, Fellowship Hall Input and output channels.
The Volume 8 Panel3 can be used to increase or decrease the sound level of the Fellowship Hall Mixer
input channels and the Fellowship Hall output channel (volume of the speakers in the Fellowship Hall).
The panel also includes a very rudimentary display of the current settings with five (5) lights. As the
volume is increased the lights turn sequentially from off, to yellow and then to red indicated the setting
of the volume control. This is not a meter, but instead indicates the current setting of the level control.
The ‘Master’ level control is always functional when sound is being played in the Fellowship Hall and
impacts the level of sound played in the Fellowship Hall. The other level controls will only impact the
sound when the sound source is the Fellowship Hall. The following table shows the volume controls
impacted by the Volume 8 Panel3:

The action is performed even if the channel is muted, so it will have an impact when the mode is changed. In addition the level is not reset
when the system is turned off, the last settings for each channel are retained.
When in ‘Sanctuary Only’ mode (‘Combined Mode’ on Panel) only the Main Mix can be heard in the Fellowship Hall. When in ‘Fellowship
Hall Only’ Mode (‘F.H. Mode’ on Panel) the main mix cannot be heard, but all the other inputs can be combined and heard simultaneously
in the Fellowship Hall, on the Auxiliary Speakers and are sent to ‘Line Out’.
Changing the ‘Master Vol.’ will increase or decrease the sound level in the Fellowship Hall in both modes.
In the ‘Fellowship Hall Only Mode’ the level of sound of each input in the final sound (the Fellowship Hall Mix) is controlled by changing
the level of each input. In essence the Volume 8 panel3 operates as a ‘mini-mixer’ with channel 1 operating as the main fader and
channels 2-8 operating as channel faders for each input.

Sound Recording
Sound that is played through the MUMC Sound System can be recorded for editing and later
playback. As noted in ’Input’ section of this this document, sound can be captured from
multiple sources (Microphones, CD/Cassette Deck, Video PC and Direct-in Box). The sound can
then follow one of two paths through the MUMC Sound System (refer to ‘Mixers and
Processors’ section’ of this document) and where the sound can be recorded (Sound PC and/or
Cassette Recorder) depends on the path it follows. Note that the MUMC Sound System is a
mono system and as a result, even though both recording devices are stereo, both recorded
stereo channels will have the same sound track.
Sound PC
The ‘Line In’ jack on the Sound PC is connected to the Aux Send 4 jack on the Mackie Mixer. It
can only record sound that has been routed through the Mackie Mixer (Mackie Mixer Sound
Path) and CANNOT record sound that has been routed directly to the Nexia CS Sound Processor
(Direct Digital Sound Processor Path) including the four (4) XLR MIC input jacks in the Fellowship
Hall. The Sound PC has Audacity installed and this program can be used to capture sound, edit
the sound and convert the sound to an MP3 file for uploading to the Internet. Please note that
the resulting sound files can be very large.
Cassette Recorder
A Tascam 102 MKII Cassette Recorder is located in the counter equipment rack and is
connected to a terminal strip that in turn is connected to Output Channel 6 on the Nexia CS
Sound Processor (Line Out). Any sound routed through Nexia CS Sound System Output Channel
6 (Line Out) can be recorded on the Cassette Recorder. This can include sound routed through
either Sound Path. That means that sound captured on the four (4) XLR MIC jacks in the
Fellowship Hall can only be recorded on the Cassette Recorder. All other sound sources can be
recorded on the Sound PC and/or the Cassette Recorder. The Output Channel 6 (Line Out) can
be ‘leveled’ by the Nexia CS Sound Processor and this is the channel recorded on the Cassette
Recorder. To disable this feature and improve the sound quality sent to the Cassette Recorder
select ‘Not Leveled’ on the ‘Main Control’ screen1 of the daVinci program on the Sound PC.

MUMC Sound System Summary
The MUMC Sound System was initially installed when the church was built in 2005. When the
system was installed it used the most current ‘state-of-the-art’ sound technology that was
available at that time. Middle to high-end commercial grade components were used and the
system is primarily an analogue system with computer control limited to the Nexia CS Sound
Processor. More modern sound components do contain some features not available in the
current system (ex. USB Output from the Mackie Mixer), but they operate in substantially the
same way as the current MUMC Sound System. Replacing the current components would not
provide significant improvements in sound quality.
A Dynamic Sound Processor was added in September, 2014 to level the sound inputs from the
Wireless Handheld and Lapel MICs. At that time the system was ‘retuned’ and the Nexia CS
Sound Processor was reprogrammed. To better utilize the Nexia CS Sound Processor, a Sound
PC was added and connected through a wireless connection to the Nexia CS Sound Processor.
The Sound PC is used to digitally record sound from the Mackie Mixer and control/monitor 1 the
Nexia CS Sound Processor. These changes did improve the sound quality somewhat, but
significantly improved the flexibility of the system.
Limitations
As with any system, although more than sufficient to the meet the church’s current needs, the
MUMC Sound System has the following limitations:
Inputs
The church currently has five (5) condenser microphones, five (5) dynamic microphones and
three (3) direct-in boxes with the cables required to connect them to the MUMC Sound System.
The church has never used all the microphones at one time, but there have been rare occasions
where the lack of a specific type of MIC has limited what can be done in the following areas:

Piano MIC
We do not have a MIC specifically designed to capture sound from a piano. As a result
we are forced to use a condenser MIC and leave the piano lid up. Occasionally when the
condenser MICs are required elsewhere, we are forced to capture the sound from the
piano as ambient sound on the other MICs (we therefore cannot control the level of
sound from the piano impacting the quality of the recorded sound).

Drum MIC
We do not have any MICs that are designed to capture the sound from a drum set and
our current MICs do not function well in that environment.
MUMC Sound System
Page | 44
Outputs
The Kitchen, Crying Room and Sunday School Room are combined on a single output channel.
As a result the sound level in these areas cannot be individually controlled from the sound
room, but instead are controlled by wall mounted Volume Controls in each room. So far this has
not presented a problem, but it is a limitation of the system.
Ease of Use
The current MUMC Sound System is not automated and requires a trained operator to run the
system. Since the Mackie Mixer cannot retain multiple settings, any change to the
configuration (adding new MICs, changing the location of a MIC, etc.) requires time and testing
before it can be implemented. This was a limitation of sound systems when the current system
was installed, but newer systems do provide automation of the many of the functions done on
the Mackie Mixer that are currently done manually at MUMC.
Age
The major components in the current MUMC Sound System are approaching 10 years in age. As
with any technology, those components have a limited but unpredictable lifespan. Therefore
the church should anticipate that over the coming years one or more of the sound components
will fail and require replacement. This is especially true of the Mackie Mixer. The model of
Mackie Mixer used at MUMC has a history of failing, in specific the connections within the
mixer can fail. This causes individual channels and even groups of channels to become
unusable. If this occurs it would require either a factory rebuild of the unit (cost unknown) or
the purchasing of a replacement unit (estimated cost ~$2,000).
Future Changes and Additions
The underlying technologies used in a sound system of the type used at MUMC have not
changed significantly since the current sound system was installed. The move to digital sound
processors occurred just before the installation of the current system and a top-of-the-line
digital sound processor (Nexia CS unit) is included in the current system. As noted earlier,
replacing the current system with a newer system would not provide significant improvements
in the sound quality at MUMC. There are, however, additions that could be made to the
system that would increase the ability to handle specific situations and/or the ‘ease of use’ of
the MUMC Sound System:
Additional Microphones
It is recommended that the following types of microphones be added to the system as, and
when, the need arises:

Piano MIC: Adding a piano MIC would provide additional flexibility in meeting situations
where the existing condenser MICs are needed elsewhere and improve the quality of
sound captured from the piano (estimated cost ~$450).
MUMC Sound System
Page | 45

Condenser MIC: Condenser MICs are very flexible and can be used to capture sound
from groups, individual performers, musical instruments and even ambient sound in a
room. Since they have a wide pick-up range, they are also excellent for inexperienced
performers. The church currently has three (3) condenser MICs and all three are used on
a typical Sunday. Adding one or two additional condenser MICs would add flexibility to
the system (estimated cost ~$150 to ~$450 per MIC).

Drum MIC Set: Over the last five years there have been one or two occasions where this
capability was required. If it happens again we should purchase a Drum MIC Set to
handle this situation (estimated cost ~$200 to ~$500).
Audio Control System
The one area where there has been significant improvements in the technology since the
current system was installed is in computer automation. Although expensive (up to 4 times as
expensive as a comparable manual mixer), they can automate many of the functions performed
by a sound operator. That would reduce the amount of training required for a sound operator
and ensure consistency between different operators. When, and if, the current Mackie Mixer
fails this option should be considered before a replacement manual mixer is purchased.
Audio Conferencing
The Nexia CS Sound Processor has significant capabilities to support audio conferencing
including ambient sound compensation, last MIC hold, open MIC limits, auto mixers, mix minus
(specialized mixing for audio conferencing) and much more. Using the MUMC Sound System for
this purpose would require the addition of specialized audio conferencing microphones, but the
system is very capable of supporting audio conferencing if ever needed by the church.

Appendix A: Troubleshooting
The purpose of this Quick Reference Guide is to provide steps you can follow to resolve
common problems you may encounter when operating the MUMC Sound System.
Feedback
Changes in the weather, the number of people in the room, the type of sound you are
capturing, the location of objects in the room or almost anything else can impact the potential
for feedback in a sound system. As a result the setup that worked last week (or even for the
last year) may create feedback today. The steps you should take to eliminate feedback depends
upon where the MIC is located as listed below. Also please note that eliminating feedback in a
sound system is more of an art than a science. As a result you may have to repeat the following
steps multiple times until you achieve the desired results.
Sanctuary MICs
MICs plugged into the XLR jacks in the Sanctuary are initially connected to the Mackie Mixer
and therefore the following steps relate to changes to the Mackie Mixer settings:
Step
1
2
3
Action
To immediately stop the feedback so you can think, mute the input channel
that is creating the feedback. You can also use ‘mute’ to determine which
channel is creating the feedback.
Once you have identified which channel is causing the feedback, adjust the
‘trim’ for that channel until the feedback stops. This changes the level of
amplification or attenuation that is applied by the Mixer to the input from this
MIC (the level of MIC ‘hotness’).
When you change the ‘trim’ you will affect the sound level of this source. This
will require changing the channel fader for the affected channel to achieve the
proper sound level in the mix. This can, in turn, reintroduce the feedback
requiring a readjustment of the ‘trim’. Adjusting the ‘trim’ for a channel also
changes the sound level for all the Aux Sends (Monitor A, Monitor B and the
Sound PC) on that channel, requiring a readjustment of the Aux Send knob for
each Aux channel to maintain the proper sound mix.
If you cannot achieve the desired sound level without creating feedback
proceed to the next step.
MUMC Sound System
Appendix B: Adding or Moving a Sanctuary MIC
Page 47
Step
4
5
Action
The next step you can take is to reposition the MIC. This is especially true if the
MIC is a condenser MIC (they have a large pickup range). Note where the MIC is
positioned relative to the main speakers and stage monitors. The dynamic and
condenser MICs used by the church only pickup sound that originates in front
of the MIC, so if you reposition the MIC so that the speakers are behind the
MIC this will reduce the potential for feedback. But sound bounces off walls
and other objects including people, therefore moving the MIC does not
guarantee the elimination of the feedback.
If the MIC is a condenser MIC, the next step is to change the MIC to a dynamic
MIC. This will dramatically reduce the pickup range of the MIC and may not be
possible if you are trying to capture the sound from a group. Inform the
performer of the MIC change and if they are inexperienced instruct them on
using a dynamic MIC.
Fellowship Hall MICs
MICs plugged into the one of the four (4) XLR MIC jacks in the Fellowship Hall are directly
connected to the Nexia CS Sound Processor and therefore many of the steps relate to changing
the settings on the Nexia CS Sound Processor. This can be done on the Volume 8 Panel3 in the
Fellowship Hall or through the daVinci program1 on the Sound PC.
Step
1

Action
If you do not have access to the Sound PC proceed to Step 3. If you have access
to the Sound PC you can immediately stop the feedback by muting the input
channel that is creating the feedback. You can also use ‘mute’ to determine
which channel is creating the feedback.
Once you have identified which channel is causing the feedback, use the
daVinci program to adjust the volume for that channel until the feedback stops.
If you cannot achieve the desired sound level without creating feedback
proceed to the Step 4.
If you do not have access to the Sound PC, use the Volume 8 Panel3 to reduce
the volume of the suspected input jack until the feedback stops. This is done by
pressing the knob until the light next to the desired jack is lite, then rotate the
knob counter-clockwise to reduce the volume of that input.
If you cannot achieve the desired sound level without creating feedback
proceed to the next step.

The next step you can take is to reposition the MIC. This is especially true if the
MIC is a condenser MIC (they have a large pickup range). Note where the MIC is
positioned relative to the ceiling speakers in the Fellowship Hall. The dynamic
and condenser MICs used by the church only pickup sound that originates in
front of the MIC, so if you reposition the MIC so that the speakers are behind
the MIC this will reduce the potential for feedback. In the Fellowship Hall there
is one ‘dead’ zone next to the Crying Room door and behind any ceiling
speaker. Since all the ceiling speakers will be in front of the MIC positioned at
this location, it will significantly reduce the potential for feedback. However
sound bounces off walls and other objects including people, therefore even
moving the MIC to the ‘dead’ zone does not guarantee the elimination of the
feedback.
If the MIC is a condenser MIC, the next step is to change the MIC to a dynamic
MIC. This will dramatically reduce the pickup range of the MIC and may not be
possible if you are trying to capture the sound from a group. Inform the
performer of the MIC change and if they are inexperienced instruct them on
using a dynamic MIC.

No Sound
Even when you have followed the startup procedures, when you test the system there could be
no sound in one or more of the speaker zones in the church. Resolving this problem can be
difficult because the problem can reside in one of multiple locations. Don’t panic and perform
the following steps to isolate and then resolve the problem:
Step
1
Action
The first step is to check that a signal is being received (signal present) by
checking the Mackie Mixer or the Nexia CS Sound System. If the source is from
the Sanctuary check the Mackie Mixer or if the source is from the Fellowship
Hall check the Nexia CS Sound System as follows:
Mackie Mixer:
If the problem relates to a source connected to the Mackie Mixer check
the -20db LED (signal present indicator) for the source channel to
ensure the Mackie Mixer is receiving a sound signal (the light is
flickering on and off).
If it is flickering (a signal is being received) proceed to Step 5.
If it is not flickering (a signal is not being received) check that the ‘trim’
control for the source is set correctly and not set to ‘0’. If the ‘trim’ is
set to ‘0’ then nothing you do will work because the Mackie Mixer is
‘muting’ the source before it is received. If a signal is still not being
received after the ‘trim’ is set correctly proceed to the next step.
Nexia CS Sound Processor:
If the problem relates to a source in the Fellowship Hall Mix (a MIC
plugged into one of the four (4) XLR jacks in the Fellowship Hall, the
Wireless Lapel MIC, the Wireless Handheld MIC or the Cass/CD Player)
check that the Nexia CS Sound Processor is receiving a signal by
checking the input levels for the source channel in the “Main
Control’screen1. Check that the input channel is not muted and then
check the meter for activity. If the meter shows little or no activity (less
than -30db on the meter) this indicates that a signal is not being
received and you should proceed to the next step. If the meter shows
activity (-20db or greater) then a signal is being received and you should
proceed to Step 5.
If you do not have access to the Sound PC go the Volume 8 Panel 3.
Select the source in question and ensure a least 3 red volume lights are
lite. At this point you do not know if you have a sound signal or not, so
if the problem is not resolved proceed to Step 5 assuming you do have a
signal. Proceed through Step 8 and if the problem is not resolved return
and proceed to Step 2.

Action
Step 2 (this step), Step 3 and Step 4 assume that a source signal is not present.
First check that the sound source is turned on and generating sound as follows:
Dynamic MIC: Check that the MIC is on.
Cass/CD Player: Check that the unit is on, that a CD is inserted and that the
CD is playing. Use the headphones to ensure the CD has sound.
Wireless MICs: Check that the unit is on and that the batteries are charged.
For the Wireless Headset check that the receiver is on.
Video PC: Check that the sound driver on the Video PC is functioning and
that the Video PC is generating sound. Additional Steps to resolve a
problem with the Video PC are included in the MUMC Video Manual,
‘Appendix D: Playing Sound from the Video PC’.
If any of the above is false resolve the issue and repeat Step 1. Otherwise
proceed to the next step.
Turn the sound system off, wait one minute and then perform the ‘MUMC
Sound System Startup’. Repeat Step 1 and if the problem still exists proceed to
the next step.
Unplug and then re-plug the cables that connect the source to the XLR jack and
then repeat Step 1. If this fails to resolve the problem try a different cable and
then repeat Step 1. If a signal is still not present try a different MIC and repeat
Step 1. If this point if you are still not receiving a signal, or you do not have
access to the Sound PC and no sound is heard even after you performed all the
recommended steps, then something is seriously wrong and the Sound System
needs to be serviced by a qualified audio technician.
If a signal is being received you need to check that the output levels are high
enough so that the sound can be heard. Do the following based on the location
where the sound cannot be heard:
Sanctuary: Check that the main mix on the Mackie Mixer is not muted
(that the ‘Tape Return to Main Mix’ button is up/disengaged) and the
Main Fader is set to its normal level or ‘0’.
Fellowship Hall: On ‘Main Control’ screen1 check that the FH mute is
not on and that the FH Output Level is set to -20db or higher. If you do
not have access to the Sound PC go to the Volume 8 Panel3Error! Bookmark
ot defined. in the Fellowship Hall and ensure the ‘Master Vol.’ level shows
at least three (3) red lights.
Aux. Speakers: This includes the Kitchen, Crying Room and Sunday
School Room. Locate the control knob in each room and ensure they
are set to ‘7’ or higher.
MUMC Sound System
Appendix B: Adding or Moving a Sanctuary MIC

Step
Action
Ext. Speaker: On ‘Main Control’ screen1 check that the ‘External Speaker
Output Level’ is at -15db or higher. If you do not have access to the
Sound PC go to the Select 8 Panel2 in the sound room and select the
‘Ext. Speaker High’ preset (the External Speaker Level is set to ‘0’). If the
problem is only with the external speaker and this did not resolve the
problem go directly to Step 9.
Sound PC: Go directly to Step 10.
6
If the output sound levels are set correctly and sound is still not heard proceed
to the next step.
If a signal is being received and the output levels are set correctly then the
problem resides in the Nexia CS Sound Processor. You should check that the
source and output channels are active (sound is being processed from the
source or sound is being sent to the output) by checking that the proper
‘preset’ is active in the Nexia CS Sound Processor. This can be done through
‘Main Control’ screen1 or from the Select 8 Panel2 in the sound room.
The following sources and/or outputs are inactive (not processed) depending
on the ‘preset’ selected:
 Sanctuary Dedicated (Combined on the Select 8 Panel2): The Fellowship
Hall Mix (including the Fellowship Hall XLR jacks) is inactive.
 F.H. Only (F.H. Mode on the Select 8 Panel2): The Sanctuary Speakers,
Monitor A, Monitor B, the Sound PC and every source connected
through the Mackie Mixer are inactive.
 Sanctuary Only (not available on the Select 8 Panel2): The Fellowship
Hall Mix (including the Fellowship Hall XLR jacks) and the speakers in the
Fellowship Hall are inactive.
 Fellowship Hall Dedicated (not avail on the Select 8 Panel2): The Sound
PC, Monitor A, Monitor B, and every source connected through the
Mackie Mixer are inactive.
7
If the ‘preset’ is correct and sound is still not heard proceed to the next step.
On the ‘Main Control’ screen1 press the ‘Volume Reset’ button. This will
unmute all channels and reset all sound levels in the Nexia CS Sound Processor
to ‘0’.
If you are still not hearing sound and/or you do not have access to the Sound
PC proceed based on the following:

Fellowship Hall Source: If the source of the sound is from the
Fellowship Hall proceed to Step 8.

Sanctuary and/or Fellowship Hall: If sound is still not playing in the
Sanctuary and/or the Fellowship Hall something is seriously wrong and
the Sound System needs to be serviced by a qualified audio technician.
Fellowship Hall Source:
On the ‘Fellowship Hall Control’ screen1 check that the source is selected in
‘Fellowship Hall Mix’ box, that the signal is greater than -20db on the FH RMS
Meter, that the channel is not muted and that the ‘FH Level Control’ for the
channel is set to -20db or higher. If at this point if you are still not hearing
sound then something is seriously wrong and the Sound System needs to be
serviced by a qualified audio technician.
If you do not have access to the Sound PC go the Volume 8 Panel3Error! Bookmark not
efined. and check the volume of the source and the ‘Master Vol.’ are set high
enough (at least 3 red lights are lite). If at this point you are still not hearing
sound then assume you are not receiving a signal from this source and return
to Step 2.
External Speaker:
If the external speaker is not playing any sound then you need to ensure the
speaker is getting sound from the correct source (Main, Cass/CD or the
Fellowship Hall):
On the ‘Main Control’ screen1 click on the button for the correct external
speaker source. Although covered in previous steps; you should check that the
source channel is not muted, sound is present on the source channel (Input
Meter), the External Speaker output channel is not muted, the external speaker
output level is set to -10db or greater and sound of -20db or greater is present
on the output channel (Output Meter).
If you do not have access to the Sound PC go to the Select 8 Panel2 in the sound
room and then turn the knob until the light next to the correct source is lite
(they are not labeled: light 3 is Cass/CD, light 4 is the Fellowship Hall and light 5
is the Main Mix from the Mackie Mixer). Push the knob in to select the source
and the light will turn to green.
If at this point you are still not hearing sound then something is seriously wrong
and the Sound System needs to be serviced by a qualified audio technician.

Sound PC:
If sound is not being received and/or recorded by the Sound PC do the
following:
a) Start a recoding in Audacity by clicking on the record button. Check the
input meter in Audacity and/or the headphones connected to the Sound
PC. Note that the meter will not show activity and sound will not be
‘passed through’ to the headphones unless Audacity is recording
(recording can be paused).
b) If sound is not present on the meter and/or in the headphones check
that Audacity is set to the proper input by clicking on the box next to
the microphone symbol (should be set to ‘Line In’).
c) Check that the ‘Line In’ input channel has not been muted on the Sound
PC by opening ‘Dell Audio’ on the Window’s desktop. Check that ‘Line
In’ is not muted and the level is at 80% or higher. Check that the
‘Speakers’ are not muted and the level is at 70% or higher. Check that
‘Speaker Enhancement’ and ‘Microphone Enhancement’ are off.
d) As a last step do a normal shut-down of the Sound PC, wait 1 minute
and then turn on the Sound PC. Sign onto the PC, start Audacity, wait
until all drivers are loaded and then repeat Step a).
Workaround: If the above does not work a temporary workaround is to switch
the output from the Sound PC to the Video PC and then use the Video PC to
record sound. Do this by unplugging the cable connected to Aux Send 4 at the
back of the Mackie Mixer and plugging in the cable connected to the Video PC.
This cable is laying behind the Mackie Mixer and has a 1/4 inch TRS plug. Go to
the Video PC and ensure that the sound driver is working. Start Audacity on the
Video PC and proceed with recording.
If the above does not work then something serious is wrong with either the
sound system and/or the Sound PC. Ask for help from someone who is
qualified and familiar with our system.

Appendix B: Adding or Moving a Sanctuary MIC
The purpose of this Quick Reference Guide is to define the steps required to add a new
microphone/Direct-in Box in the Sanctuary (even one the church already has), or to move a
MIC/Direct-in Box already connected to the system to a different XLR jack in the Sanctuary.
These steps do not work for a MIC/Direct-in Box connected to one of the XLR jacks in
Fellowship Hall. The following steps should be done well before the performance begins.
MIC Setup
Perform the following steps to add a new MIC/Direct-in Box or move an existing MIC/Direct-in
Box to a new XLR jack in the Sanctuary. These steps will add the MIC/Direct-in Box to the
Mackie Mixer and to the main mix that plays on the speakers in the church.
Step Action

Turn the 'Trim' to 0 and set the 'Channel Fader' to “∞“ (Infinity) for the selected
channel. Add this channel to the main mix by ensuring the 'L-R' button for the
selected channel is DOWN. Engage 'Mute' for the selected channel. Set all the Aux
Send channel knobs for this channel to ‘0’. Set the ‘SOLO’ mode to Pre-Fader Listen
(PFL Mode, ‘Solo’ Mode button is up). If possible turn the system off to avoid ‘spikes’
when cables are connected.
Connect the MIC or the Direct-in Box to the proper input jack. Do NOT use a 'patch'
cable to connect a non-MIC directly to an XLR jack, the impedance levels are not the
same and this can result in damage to the system. Instead use the Direct-in box. Pay
attention to where a MIC is placed relative to the main speakers and stage monitors
(this is especially important for condenser MICs). If the system is off, you can now
turn the system on.
Ensure MIC/Direct-in Box is turned on (Condenser MICs are always on). Ensure the
Main Mix is not muted (‘Tape Return to Main Mix’ is up/disengaged) and the Main
Mix Fader is set to its normal level or ‘0’. Disengage the mute for the selected
channel.
If you are connecting a MIC turn the ‘Trim’ knob for the selected channel up until you
hear feedback and then turn back down until no feedback is heard. If no feedback is
heard or you are connecting a Direct-in Box set the ‘Trim’ knob for the channel at ‘U’
(Unity). Reengage ‘Mute’ for the selected channel.
Have someone make noise at the anticipated level and location for the MIC, or play
the instrument if you are using a Direct-in Box. Ensure that the -20 dB light for the
channel is flashing green, this indicates that sound is present. If it is not flashing then
check your connections, ensure the MIC/Direct-in Box is turned on, and then repeat
step 4.

While making noise or playing the instrument, engage that channel's 'SOLO' button.
Ensure all other 'SOLO' buttons are off (UP). The Rude Solo LED will now flash red. If
you are using a Direct-in Box or you did not hear feedback in Step 4, adjust the 'Trim'
knob for this channel until the Meters peak near '0'.
Change the ‘SOLO’ mode to AFT (After Fader Listen) by pressing the ‘SOLO’ mode
button down. While continuing to make noise, disengage the channel's 'Mute'.
Monitor with headphones and slowly raise Channel Fader until the proper sound
level is obtained. Adjust the EQ as desired.
Remove the headphones. Disengage 'SOLO' for the selected channel (UP). Ensure the
Main Mix is not muted (‘Tape Return to Main Mix’ is up/disengaged) and the Main
Mix Fader is set to its normal level position or ‘0’. Disengage the mute for the
selected channel (red light will go off).
While continuing to make noise, monitor for feedback and adjust 'Trim' as necessary.
'Mute' the channel if you cannot quickly resolve feedback. EQ can also be used to
reduce feedback (room is sensitive to 800Hz feedback). Adjust the ‘Channel Fader’
for the selected channel to achieve the proper sound level. If you cannot achieve the
proper sound level without feedback reposition the MIC. If you are using a condenser
MIC you can also change to a dynamic MIC (they have a much shorter pickup range).
Before a rehearsal or performance begins ensure the performers know the type of
MIC they are using (condenser or dynamic). During the rehearsal or performance
readjust the 'Channel Fader' for the input channel where the new MIC/Direct-in Box
is connected to add the new MIC/Direct-in Box to the main mix. Continue to monitor
for feedback.
At this point the new MIC has been included in the main mix but it is not included in mix for
Monitors or the computer output. Since the stage is a dead zone, performers cannot hear the
sound from this MIC until you include it in the mix for the monitors. In addition the sound from
this MIC will not be recorded on the Sound PC. Since the Cassette Recorder records the main
mix, it will be included in a cassette recording. If you want the sound included on the monitors
or recorded on the Sound PC you should perform the following steps.

input channel to ‘0’.
Ensure MIC/Direct-in Box is turned on. Have someone make noise at anticipated
level and location for the MIC or play the instrument for the Direct-in Box. Check the
-20dB LED to ensure sound is present.
To add the new MIC/Direct-in Box to the stage monitors (Monitor A) disengage the
mute for the selected channel (red light is off). Engage the ‘SOLO’ for Master Aux
Send 1 if you want to check the sound level using the meters or the headphones.
Even though the main mix is mute, sound will still be routed to the stage monitors
and therefore you may get feedback.
Slowly turn up the Aux Send 1 for the selected channel while monitoring for the
desired sound volume and feedback (stage monitors can be sensitive to feedback
depending on the placement of the MIC). 'Mute' the input channel if you cannot
quickly resolve feedback. EQ can also be used to reduce feedback (room is sensitive
to 800Hz feedback). The sound from the new MIC/Direct-in Box has now been added
to the stage monitors (Monitor A: Aux Send Master 1).
Turn main mix ‘mute’ off (disengage ‘Tape Return to Main Mix’ and/or slide the main
mix fader back to its normal location).
At the beginning of the performance or rehearsal disengage all other channel’s
‘SOLO’ so the Rude Solo LED is off. Engage the ‘SOLO’ for Aux Send Master 1
(Monitor A) and monitor it using the headphones to ensure the new MIC/Direct-in
Box is at the proper level for the stage monitors.
Monitors are for the performers and each performer is different. If at all possible
check with the performers during a rehearsal to ensure the monitors are at the
proper level and the mix is correct. Adjust as necessary until the performer is happy.

Ensure MIC/Direct-in Box is turned on. Have someone make noise at anticipated
level and location for the MIC or play the instrument for the Direct-in Box. Check the
-20dB LED to ensure sound is present.
To add the new MIC/Direct-in Box to the pianist’s monitor (Monitor B) disengage the
mute for the selected channel. Ensure all other 'SOLO' buttons are off (UP) and then
engage the ‘SOLO’ for Aux Send Master 2. Disengage the mute for the selected
channel. Even though the main mix is muted, sound will still be routed to the stage
monitors and can be heard in the Sanctuary.
Slowly turn up the Aux Send 2 feed for the selected input channel while monitoring
for volume using the Headphones and/or the meter (the Pianist’s Monitor is rarely
sensitive to feedback because of its placement and sound level). Please note that
sound is also being routed to the stage monitors (Monitor A), but they are not
affected as you adjust Aux Send 2 (to adjust the stage monitors see
Stage Monitors (Monitor A) Setup’). That is why you should use the
headphones/meter when adjusting the level Aux Send 2 (Monitor B) for this channel.
The sound from the new MIC/Direct-in Box has now been added to the Pianist’s
Monitor (Monitor B: Master Aux Send 2).
Turn main mix ‘mute’ off (disengage ‘Tape Return to Main Mix’ and/or slide the main
mix fader back to its normal location).
At the beginning of the performance or rehearsal disengage all other channel’s
‘SOLO’ so the Rude Solo LED is off. Engage the ‘SOLO’ for Aux Send Master 2

Enable ‘SOLO’ for the Aux Send Master 4 (press the Solo button for Master Aux Send
4 down). The Rude Solo LED and the Solo Aux LED will now flash red.
Ensure the MIC or the Direct-in Box is turned on. Have someone make noise at
anticipated level and location for the MIC, or play the instrument if you are using a
Direct-in Box. Check the -20dB LED to ensure sound is present.
Disengage the mute for the selected channel and slowly turn up the Aux Send 4 feed
for the selected channel monitoring the results on the headphones and the meter.
Adjust the Aux Send 4 feed for selected input channel as necessary. Since Master
Aux Send 4 does not play anywhere in the church, there is no danger of feedback as
you adjust the Aux Send 4 for the selected channel. If there is feedback the MIC was
setup incorrectly and you should refer to ‘MIC Setup’ or ‘Appendix A:
Troubleshooting’.
At the beginning of the performance or rehearsal ‘SOLO’ Aux Send Master 4
(disengage all other channel’s ‘SOLO’ so the Rude Solo LED is off and then engage the
‘SOLO’ for Aux Send Master 4) and monitor it using the headphones to ensure the
new MIC is at the proper level for the mix sent to the Sound PC. Readjust Aux Send 4
for the selected channel as necessary. Do not readjust the Master Aux Send 4 knob
unless you are having a problem with the overall sound level of the Aux Send Master
4 mix.
Record a performance and check the results to ensure the recording meets your high
expectations.

Appendix C: daVinci Program1
The daVinci program allows you to monitor and change the Nexia CS Sound Processor either
before, during or after a performance. The daVinci program downloads a control surface from
the Nexia CS Sound Processor and therefore you can monitor and control the Nexia CS Sound
Processor from any PC that has daVinci installed and is connected to the sound system’s
wireless router.
Startup
Before starting the daVinci Program you should start or ‘turn on’ the MUMC Sound System.
The MUMC Sound System has an integrated power system that will turn on all of the sound
system components (except the Sound PC) when the power switch on the counter sound
equipment rack is turned on.
Sound PC
Wait ~15 seconds after the MUMC Sound System has been turned on before you start the
daVinci program on the Sound PC to ensure all the sound system components are fully ‘up’. If
the Sound PC is off, turn the Sound PC on and sign on to Windows (User ID ‘Motley UMC’ and
password ‘Cross6466’). Wait until all drivers are up and Windows is fully loaded before starting
daVinci.
After the Sound PC is fully booted, double-click on the daVinci icon on the Window’s desktop to
start the daVinci program. The daVinci program on the Sound PC has been setup to
automatically connect to the Nexia CS unit, download the control surface and then run that
control surface in a window on the Sound PC. If daVinci shows an error then the Nexia CS unit
was not fully started. Close daVinci, wait at least 15 seconds and then restart daVinci.
A window with meters, level controls and buttons will display in a window on the Sound PC.
You can now use the control surface to monitor and control the Nexia CS Sound Processor. If
the connection to the Nexia CS unit is lost and/or the sound system is turned off, the daVinci
program will display an error and close. Correct the problem (ex. turn on the sound system) and
then restart daVinci.
Other PC
You can use the daVinci program on any PC that is connected to the Sound System’s wireless
router. First install the daVinci program on the PC. The setup file is located on the Video PC in
the directory ‘C:/Users/Public/Public Downloads/Biamp/daVinciSetup2.3’. Copy this program
to the PC and then run it to install daVinci.
MUMC Sound System
Appendix C: daVinci Program
Page | 60
Network Setup
After the daVinci program is installed you need to setup the PC to communicate with the Nexia
CS unit. Connect your PC to the Sound System wireless router (NETGEAR53) and check to
ensure you have access to the Internet. The password is in the top middle drawer of the sound
room counter. Connecting to the church’s main wireless network (Motley UMC) will not provide
access to the Nexia CS unit.
Opening the Control Surface
After you have connected to the Sound System wireless router (NETGEAR53) start the daVinci
program on your PC. Use the File Menu or the Network Bar to connect to the network. The
program will connect to the network and then search for Nexia units on the network. It will
then will display the ‘System Connect’ screen:
Select the appropriate Nexia CS unit (there is only one in our system) and click on ‘Open Control
Surface’. No user name or password is required since the system is protected by the firewall in
the Sound System wireless router. A control surface with meters, level controls and buttons
will display. You can now use the control surface to monitor and control the Nexia CS Sound
Processor. If the connection to the Nexia CS unit is lost and/or the sound system is turned off,
the daVinci program will display an error and close. If this occurs correct the problem, reestablish a connection to the Sound System wireless router (may occur automatically) and
repeat this step.
MUMC Sound System
Appendix C: daVinci Program
Page | 61
Using the Control Surface
The control surface contains a set of meters, mutes, level controls and buttons that can be used
to monitor and control the Nexia CS Sound Processor. Buttons and ‘mute’ are activated by
clicking on the appropriate icon in the control surface. Sound levels can be changed by moving
the appropriate slider up/down, or double-clicking in the black box under the slider or keying in
a number (remember to key in the minus sign as the first character). Muting a channel will
mute the channel before the meter and does not impact the level setting. The functions are
located on a ‘Main Control’ screen and a ‘Fellowship Hall’ screen. A button at the top-right of
each screen allows you to change screens.
Main Control Screen
The ‘Main Control’ screen is divided into the following sections:

Volume Reset
The Volume Reset button will unmute and return to ‘0’ all level controls. This is an easy
way to return the system to a known state.

Fellowship Hall
The Fellowship Hall button will take you to the Fellowship Hall Control Screen.

Input Levels
This section of the screen provides meters and mute buttons for the 10 inputs
connected to the Nexia CS unit (only 9 inputs are used, channel 10 is unused and
normally muted). If the meters are showing sound above -20db then a sound signal is
being received. If the level is below -30db then the meter is probably showing ‘noise’
that is present in any sound system. If the meter consistently extends into the yellow or
red zone then the signal is too ‘hot’ and should be muted (can happen with feedback is
occurring). Turn down the source to resolve the problem. You can ‘mute’ any input by
clicking on the ‘mute’ button for that channel.

MID Levels and Controls
This section of the control surface includes the meters, mute buttons and level controls
that have been included in the Nexia CS program after the inputs have been converted
to digital but before the sound is mixed (Main, Monitor and Cass/CD mixers). This
allows you to control the level or mute any of these inputs before they are mixed for
output.

Output Levels and Controls
These meters show you the output level that is being sent to the speakers and line out.
The level controls and mute button allow you to control the sound level throughout the
MUMC Sound System
Appendix C: daVinci Program

church by controlling the level of sound output by the Nexia CS Sound Processor on each
output channel.

Preset Mode
This section allows you to select which preset is active. Presets control what inputs
(sources) and outputs are active/inactive, and control how sound is mixed in the Nexia
CS Sound Processor. A description of each present is included in the ‘Nexia CS Presets’
section of the ‘MUMC Sound System’ document. The blue light next to the button is lite
to show which preset is currently active.

Ext. Spk. Source
This section controls what source is output to the External Speaker. The blue light next
to each button will indicate which source is currently being output to the External
Speaker. You can also select the source from the Select 8 Panel2 in the sound room.

Ext. Spk. Level
This section controls the level of sound output to the External Speaker. The blue light
next to each button will indicate the last button that was selected (either through the
daVinci control surface or through the Select 8 Panel2 in the control room). You can also
directly control the sound level of the External Speaker by changing the level control for
the External Speaker (Ext. S.) in the ‘Output Levels’ section, but this will not change
which button is lite. The External Speaker (Ext. S.) level control is set to 0 when ‘High’ is
selected, -15 when ‘Low’ is selected and muted when ‘Mute’ is selected regardless of
the input source.

Line Out Leveling
Normally the ‘Line Out’ output channel is leveled for the Assisted Listening System. If
you want to record the ‘Line Out’ you can disable this function by clicking on the ‘Not
Leveled’ button and then return to leveling by clicking on the ‘Leveled’ button. A blue
light next to the buttons will show if the ‘Line Out’ is leveled or not leveled.

Main Mixer
This section of the control surface shows the current status of the ‘Main Mixer’ in the
Nexia CS Sound Processor. The lite boxes show which input is being routed to which
output. The External Speaker is not controlled by the ‘Main Mixer’ and therefore its
output channel is not shown. The ‘FH’ Input row is the ‘Fellowship Hall Mix’ that is
controlled on the ‘Fellowship Hall’ screen or through the Volume 8 Panel 3. The
Fellowship Hall mix is a combination of the Cass/CD, Lapel MIC, Handheld MIC and MICs
connected to the four (4) Fellowship Hall XLR jacks.
MUMC Sound System
Appendix C: daVinci Program
Page | 63
If all the boxes in a row on the Main Mixer are not lite, then the source for that row is
inactive (the source is not being routed to any output). If all the boxes in a column are
not lite, then the output for that column is inactive (no sound is being routed to the
output).
The mix (lite boxes) is changed as different presets are selected. You can manually
change the mix by clicking on a box to add or remove an input (row) from an output
(column). The entire mix (all boxes) is reset when a preset is selected.

Fellowship Hall Control Screen
The ‘Fellowship Hall’ screen is divided into the following sections:

Volume Reset
The Volume Reset button will unmute and return to ‘0’ all level controls. This is an easy
way to return the system to a known state.

Main
The Main button will take you to the Main Control Screen.

Presents
This section is a duplication of controls on the ‘Main Control’. Please reference the
‘Main Control Screen’ for a description of how to use these controls.

Fellowship Hall Source Mix
This section of the control surface depicts the current status of the Fellowship Hall
Mixer. The lite boxes show which input (Signal Source) is included in the Fellowship Hall
mix. You can manually change the mix by clicking on a box to include or remove an input
(Single Source) from the mix. Normally all inputs are included in the mix. If you remove
an input from the mix it must be added back to the mix on this screen. It cannot be
added by selecting a different preset or using the Volume 8 Panel 3 in the Fellowship
Hall.

Fellowship Hall Source Levels
This section of the control surface includes the meters, mute buttons and level controls
for each input (Signal Source) that can be included in the Fellowship Hall mix. This
allows you to monitor and control the input levels to create the mix you want. Muting a
source will remove that source from the mix, but it will not change the level control for
that source. When unmuted the channel will return to the previous sound level. The
level of each source can be controlled from this screen or from the Volume 8 Panel 3
located in the Fellowship Hall.

Fellowship Hall Output Levels
This section of the control surface allows you to control the Fellowship Hall Mixer
output (FH Mixer Output) and the sound output to the Fellowship Hall speakers (FH
Output).
The Fellowship Hall Mixer output (FH Mixer Output) is the output from the Fellowship
Hall Mixer after the sources have been leveled/combined (see above) but before it is
sent to the Main Mixer. This allows you to control the level of the Fellowship Hall mix
before it is mixed with other sources and routed to an output channel in the Main
MUMC Sound System
Appendix C: daVinci Program
Page | 66
Mixer. Muting the Fellowship Hall Mixer Output has the same impact as removing
(deactivating) the Fellowship Hall Mix (FH) in the Main Mixer.
The Fellowship Hall Output (FH Output) meter, mute and level controls on this screen
are a duplicate of the Fellowship Hall (FH) controls in the ‘Output Levels’ section of the
Main Control Screen. These controls impact the sound played in the Fellowship Hall
regardless of the source. The output level for the Fellowship Hall can also be changed
from the Volume 8 Panel3 in the Fellowship Hall.

Although it looks long (~25 steps), starting up the MUMC Sound System is not difficult and
normally can be done in less than 5 minutes (not including sound checks and as long as there
are no problems). It should be done at least 30 minutes before a performance starts to allow
time for performing a sound check if required and to resolve problems if they do occur. The
steps you take will depend on the type of performance/service and the sound source.
Sunday Service
Perform the following steps to startup the MUMC Sound System for a typical Sunday Service:

The majority of the MUMC Sound System components are powered by an
integrated power system. Turn on the power in the counter sound equipment
rack (power switch at upper-right). The integrated power system will then
power on the sound system components in the proper sequence with the
proper delays. Check that all input channels on the Mackie Mixer are muted
(the ‘Mute/Solo LED’ for all input channels is solid red) and that all the settings
on the Mackie Mixer are at their default settings (see ‘Mackie Mixer Default
Settings’).
If the Sound PC is off, turn the Sound PC on and sign on to Windows (User ID
‘Motley UMC’ and password ‘Cross6466’). Wait until all drivers are up and
Windows is fully loaded. Go to the Window’s desktop.
Double-click on the daVinci icon on the Window’s desktop to start the daVinci
program1. The program has been setup to automatically connect to the Nexia
CS unit, download the control surface and then run that control surface in a
window on the Sound PC. A window with meters, level controls, lights and
buttons will display in a window on the Sound PC. Position the daVinci window
at the top of the screen.
Check the Main Control screen in the daVinci program1 and ensure that the
active ‘Preset’ is ‘Sanctuary Only’. You can also use the Select 8 Panel2 in the
sound room to select the ‘Combined Mode’ preset (Sanctuary Dedicated). If
you use the Select 8 Panel2 mute the Fellowship Hall (FH) output channel in
the ‘Main Control’ screen1 or use the Volume 8 Panel3Error! Bookmark not defined. to
urn the Master Vol. completely down (off).
In the counter sound equipment rack turn on the Cass/CD Player. Insert the
CD you want to play on the External Speaker before the service starts and
press ‘Play’. If you are note playing sound on the external speaker insert any
music CD.
Check the Main Control screen1 and ensure that the External Speaker Source
(Ext. Spk. Source) is set to ‘Cass/CD’. You can also use the Select 8 Panel2 in the
sound room to select ‘Cass/CD’ (third light down).

In the ‘Output Levels’ section of the ‘Main Control’ screen1 check that the
External Speaker (Ext. S.) is not muted, that the level is set between 0 and -15
(-11.5 seems to work well) and that the meter is showing sound. You can also
use the Select 8 Panel2 to select the ‘Ext. Speaker Low’ preset (sets external
speaker level to -15). If the meter is not showing sound refer to ‘Appendix A:
Troubleshooting – No Sound’. If you are not playing sound on the external
speaker you can skip this step.
On the Mackie Mixer the ‘signal present’ indicator for Stereo Channel 23-24
should be flashing. If it is not flashing refer to ‘Appendix A: Troubleshooting –
No Sound’. Unmute that channel (if someone is rehearsing you can mute the
main mix). Sound is now being sent to Aux Send Master 4 (Sound PC).
Start Audacity by double-clicking on the Audacity icon on the Windows
desktop or clicking on the Audacity icon in the Windows task bar. Position the
Audacity window at the bottom of the screen below the daVinci window so
you see both windows.
Select the ‘Record’ button and then the ‘Pause’ button in Audacity. Check the
meter at the top of the Audacity window that sound is present. It should be
peaking around -12. If it is not adjust the Aux Send Master 4. If the meter is
not showing sound refer to ‘Appendix A: Troubleshooting – No Sound’.
On the Mackie Mixer mute stereo channel 23-24 and unmute the main output
if it was muted.
Check that the batteries in the wireless lapel and handheld MICs are charged.
Turn each unit on and check the battery status indicator in the LED for each
unit. If the batteries are not fully charged replace them with batteries from
the charger on the sound room counter. If necessary you can use standard AA
batteries, but never try to recharge these batteries in the charger. After
checking the battery status turn the wireless MICs off until just before the
service (save the batteries).
Ensure all channels on the Mackie Mixer are still muted.
Based on the activity in the Sanctuary, check that sound is present on the
proper input channels by checking the ‘signal present’ indicators on the
Mackie Mixer for those channels where sound is being generated close to the
MIC. When the performers are rehearsing this should include channels 4
(Sanctuary ambient sound), 8 (choir MIC), 11 (piano MIC or 2nd choir MIC), and
13 (Pulpit MIC). The ‘signal present’ indicator for Stereo channel 23-24
(Cass/CD Player) should still be flashing indicating that the Cass/CD is playing.
If one or more of the ‘signal indicators’ are not flashing even when sound is
present, refer to ‘Appendix A: Troubleshooting – No Sound’.
If sound from the Video PC is included in the Service test it now and ensure
sound is being received on the Mackie Mixer (‘signal present indicator’ for
Stereo channel 21-22 is flashing). If it is not being received refer to the ‘MUMC
Video System’ document ‘Appendix B: Playing Sound from the Video PC’.

The sound system is now ready for any sound checks you want to make before
the service starts. Check with the performers to see if some of the MICs need
to be repositioned and/or additional MICs added. If additional MICs are added
refer to ‘Appendix B: Adding or Moving a Sanctuary MIC’.
During the sound check adjust the ‘trim’ knob to eliminate feedback and the
channel fader to obtain the proper sound level for each input (source)
included in the main mix. If feedback is a problem refer to ‘Appendix A:
Troubleshooting – Feedback’.
During the ‘sound check’ recheck the input levels on the Sound PC (input
meter in Audacity). You can also ‘solo’ Aux Send Master 4 and use the
headphones to check the mix, level and quality of the sound. Use the Aux
Send Master 4 knob to adjust the sound level sent to the Sound PC. Use the
Aux 4 knob for each channel to remix the sound sent to the Sound PC. Please
note that the sound sent to the Sound PC is not impacted by the input channel
faders since Aux 4 is set as pre-fader on all channels (the signal is taped prior
to the channel fader for this channel but after the trim, mute and EQ settings).
If you want to play sound in the Fellowship Hall during the service (ex.
overflow crowd) you need to setup the Fellowship Hall sound near the end of
the sound check. If there is no sound check then use the Cass/CD Player as an
alternative sound source by unmuting Stereo Channel 23-24 on the Mackie
Mixer. Setup the Fellowship Hall sound by performing the following steps:
 In the ‘Main Control’ screen1 select the ‘Sanctuary Dedicated’ preset or
use the Select 8 Panel2 to select the ‘Combined Mode’.
 Unmute the Fellowship Hall (FH) output channel in the ‘Main Control’
screen1 if it is muted.
 Adjust the sound level in the Fellowship Hall by adjusting the
Fellowship Hall level control in the ‘Main Control’ screen 1 or the
‘Master Vol.’ on the Volume 8 Panel3Error! Bookmark not defined..
 Mute the Fellowship Hall (FH) output channel in the ‘Main Control’
screen1.
Check with the performers to determine when various MICs will be used
during the Service. Create a ‘cheat sheet’ showing which MICs will be used and
when. Post the ‘cheat sheet’ near the Mackie Mixer.
Assist the Pastor in putting on the wireless lapel MIC and make sure it is
turned on. Ensure that channel 17 on the Mackie Mixer is muted and that the
‘sound present’ indicator is flashing. If it is not flashing ensure that the unit has
not been turned off inadvertently and that it is not muted on the send unit.

Five (5) minutes before the service starts switch the External Speaker source
from the Cass/CD Player to the main mix. This will play the prelude and the
service on the External Speaker. This can be done from the Main Control
screen1 (button labeled ‘Main’) or through the Select 8 Panel2 (fifth light
down). Set the output level for the external speaker to -4 using the ‘Main
Control’ screen1.
If you are going to use a CD during the Service replace the CD in the Cass/CD
Player with the CD you are going to use. Plug the headphones into the
headphone jack on the Cass/CD Player and use the controls on the player to
queue the CD.
Just before the Service starts do the following:
 Turn on the Handheld MIC and place it to the left on the sound room
counter. It will be used to capture the bell ringing from outside and
then for the announcements at the beginning of the service.
 Occasionally someone may make an announcement (ex. birthdays or
anniversaries) from the choir MIC before the service starts. If this
happens unmute channel 8 (choir MIC) and adjust the fader for the
channel appropriately. Re-mute the channel when they are finished.
 Start the recording in Audacity on the Sound PC (click on the pause
button).
 If you are playing sound in the Fellowship Hall unmute the Fellowship
Hall output channel in the ‘Main Control’ screen1.
You are now ready for the service to begin.

the volume so that at least three red lights are lite and then do the following
for each source you are using:
 Select a source and adjust the volume until you achieve the desired
level.
 Continue to readjust the Master Vol. as more sources are added.
This is an iterative process. Repeat the above steps for each source until the
desired mix is obtained and the volume is correct.
The above steps can also be done from the ‘Fellowship Hall’ screen 1, but you
cannot hear the sound in the Fellowship Hall.
If feedback occurs at any point turn the volume down until it stops and refer
to ‘Appendix A: Troubleshooting – Feedback – Fellowship Hall MIC’ to resolve
the feedback.

15
If sound is not heard even when the volume is turned up on the source and
the Master Vol. first check that the MIC is turned on. If this does not resolve
the problem refer to ‘Appendix A: Troubleshooting – Feedback – No Sound’.
On the ‘Main Control’ screen1 do the following:
 If you want the sound captured in the Fellowship Hall played in the
Sanctuary then in the ‘Output Levels’ section adjust the volume for the
Main channel until the desired sound level is achieved.
 If you do not want sound played in the Sanctuary mute the Main
Output Channel
You cannot record the Fellowship Mix on the Sound PC, instead it can only be
recorded on the Cassette Recorder. If you want to record the
Service/Performance do the following:
 In the ‘Line Out Leveling’ section of the ‘Main Control’ screen 1 select
‘Not Leveled’.
 In the ‘Output Levels’ section of the ‘Main Control’ screen1 ensure that
the Line Out channel is not muted, the level is set to 0 and the meter
shows that sound is present.
 Turn on the Cassette Recorder in the counter sound equipment rack,
insert a blank cassette and advance past the leader.
 Plug the headphones into the headphone jack on the Cassette
Recorder.
 Press ‘Record’ on the Cassette Recorder (it will automatically pause).
 Using the headphones and the input meter on the Cassette Recorder
adjust the input to the desired level using with input dial on the
Cassette Recorder.

Action
If you are going to use the Cass/CD player you need to re-queue the CD. Plug
the headphones into the headphone jack on the Cass/CD Player and use the
controls on the player to re-queue the CD.
Check with the performers to determine when various MICs or prerecorded
sound will be used during the Service. Create a ‘cheat sheet’ showing which
inputs will be used and when. This will tell you when you need to adjust the
Volume 8 Panel3 or start the Cass/CD Player in the sound room.
In the ‘Fellowship Hall Output Levels’ section on the Fellowship Hall’ screen 1
mute Fellowship Hall (FH) Mixer Output. This will mute the Fellowship Hall
mix so no sound will be heard on the church’s speakers until just before the
Service/Performance starts.
Just before the Service/performance begins do the following:
 Check that the wireless MICs you are using are turned on.
 Check that the dynamic MICs are turned on (unless the performer is
experienced and controlling the MIC).
 Start the recording on the Cassette Recorder.
 Unmute the ‘Fellowship Hall Mixer Output’1 (see Step 18 above).
Note that the Fellowship Hall Mix is no longer muted; the MICs will capture
sound, it will be played on the church’s speakers and it will be recorded. You
are now ready for the performance to begin

Appendix E: Sound System Operation and Shutdown
Operating the MUMC Sound System is more of an art than a science. It is a matter of unmuting
the proper input channel (sound source) at the proper time, muting channels that are not being
used and adjusting the sound levels to maintain the desired mix and sound level. Some
operators make few adjustments during a Service/performance and others continually make
adjustments, there is no right or wrong way. The following are just the basic steps required to
run the sound system:
Beginning
Perform these steps at the very beginning of the service:
0
1
2
3
Just before the Service/performance starts check that the recording device
has been started (Audacity on the Sound PC and/or the Cassette Recorder)
and that all the input channels on the Mackie Mixer are muted (the
‘Mute/Solo’ lights for all input channels are solid red).
Unmute the initial input channel (source) just before the
Service/performance begins. For a Sunday Service this includes the
wireless lapel MIC (for the Pastor, channel 17) and the handheld MIC (to
capture the bell ringing, channel 18).
Adjust the input channel and the main fader to the desired sound level.
Turn down the fader and/or the ‘trim’ for the channel if feedback occurs
(this is one of the few things you can do during a performance). These
actions are continually repeated as new sources are added, sources are
removed, the mix changes, the performance changes, and/or the
environment changes (number of people, temperature, humidity, etc.).
As soon as you can check that the recorders are receiving sound (meter in
Audacity and/or the Cassette Recorder meter). Adjust Aux Send Master 4
Send for the Sound PC and the Input dial on the Cassette Recorder as
necessary. Check the quality of sound being recorded on the Sound PC by
‘soloing’ Aux Send 4 and using the headphones. You can also use the
headphones attached to the Sound PC.
MUMC Sound System
Appendix E: Sound System Operation
Page | 82
During the Service/Performance
During the Service/performance perform the following actions as required:
Unmute and mute input channels at the appropriate time. Readjust the input channel and the
main mix fader to the desired sound level whenever the mix changes (channels are muted or
unmuted).
Unmute the appropriate input channel and then start any prerecorded sound required at the
proper time (Cass/CD Player and/or Video PC).
During a Service/performance there will be occasions where the main mix is made up of
multiple input channels (sound sources). Adjust the fader for each input channel so that the
source is heard at the proper level in the main mix. You can also ‘solo’ individual channels or
groups of channels to monitor their level using the headphones and meter. If the Solo Mode
button is up the sound is PFL (pre-fader listen – before the fader for the soloed channels) and
if it is down the sound is AFL (after-fader listen – after the fader for the soloed channels).
You can also adjust the ‘balance’ of the source by using the EQ controls for individual input
channels. ‘Solo’ the channel and then use the headphones to monitor the channel as you
make adjustments.
Continually adjust the input and main faders as new sources are added, sources are removed,
the mix changes, the performance changes, and/or the environment changes (number of
people, temperature, humidity, etc.).
Continue to monitor for feedback. Turn down the fader and/or the ‘trim’ for the channel if
feedback occurs. The only other thing you can do during the Service/performance is adjust the
EQ for the channel. The Sanctuary is sensitive to feedback in the 800Hz range. Sent the MID
Range EQ to around 800Hz and then reduce the ‘gain’ for that frequency using the ‘FREQ’
knob for the input channel (next knob under the MID Range knob).
Periodically check that the recorders are receiving sound (meter in Audacity and/or the
Cassette Recorder meter). Adjust Aux Send Master 4 Send for the Sound PC and the Input dial
on the Cassette Recorder as necessary. Check the quality of sound being recorded on the
Sound PC by ‘soloing’ Aux Send 4 and using the headphones. You can also use the headphones
on the Sound PC.
One thing that can help is to know when the input channels (either MICs and/or prerecorded
sound) are going to be used during the Service/performance. Before the Service/performance
begins check with the performers and create a ‘cheat sheet’. Post the ‘cheat sheet’ near the
Mackie Mixer (or keep it with you if the sources are in the Fellowship Hall) and refer to it during
the Service/performance so you can anticipate when input channels need to muted and unmuted.
MUMC Sound System
Appendix E: Sound System Operation
Page | 83
After the Service/Performance (Shutdown)
Perform the following steps after the Service/performance to shut down the MUMC Sound
System:
1
2
3
4
5
6
7
8
9
10
Mute all the input channels on the Mackie Mixer (the ‘Mute/Solo’ LED for
all input channels should be solid red).
Stop the recording on the Sound PC and/or the Cassette Recorder. In
Audacity on the Sound PC click on the stop button. On the Cassette
Recorder press the ‘Stop’ button.
In Audacity save the recording by selecting ‘File’ and then ‘Save Project
As…’ Give the recording a descriptive name and save. This will save the
recording in an Audacity project file. You can reopen, edit and export the
recording at a later time. Close Audacity if you are not going to edit the
recording at this time. DO NOT close Audacity until you have saved the
recording.
If you recorded the Service/performance on a cassette rewind the
cassette, remove the cassette from the Cassette Recorder and then label
it. Put the cassette into its case and store it where it can be found again.
If a CD is playing stop and then turn off the Cass/CD Player.
Turn off any wireless MICs that were used.
Turn off the power in the counter sound equipment rack (power switch at
upper-right). The integrated power system will then power down the
sound system components in the proper sequence with the proper delays.
The daVinci program will time out and then close. If it does not close
automatically close the program by clicking on the ‘X’ at the upper-right of
the daVinci window.
Turn off the Sound PC monitor. Leave the Sound PC on.
If you are the last person in the sound room turn off the light and close the
door as you leave.
