Introduction

The basic Sound System was completely installed and tested on August 30, 1996 by Gulf Coast Sound & Lights (not existed anymore). First additional eqiupment was a wireless hand-held microphone added to the system on September 20, 1996. After that the system has been keep expanding. More and more equipment have been added including mixers, microphones, drum sets, keyboards, guitars, cables, microphone stands and music stands, amplifers and power supplies, projectors and screens, etc. A list of the equipment can be found in Appendix A. Note that the building is protected by CCTV and monitored security alarm system.

The Sound System

Figure 1 illustrates the current configuration of SWCBC Sound System. Figure 2 shows the location of the equipment. Inside the Sound Room (Rm 116), the Mixer (ProMix 01) sits on the counter, the two power amplifiers (QSC 850 and 370), equalizer (Q310) and tape deck (PMD510) are mounted on a rack sitting under the counter, and, the two receivers for the wireless lapel and hand-held microphones sit on the top of the shelf almost touching the ceiling.

[back to top]

Input channels 1-8 have optional "Phantom power" and thus can be used for either condenser or dynamic microphones. Comparing to dynamic microphones, condensers are less rugged and more sensitive and have wider bandwidth but require additional boosting power. Input channels 9-16 and all other input jacks do not have Phantom power and thus CANNOT be used for condenser microphones. All input channels and other input jacks can be used for any balanced "line level sources". Channels 1-8 should not be used for unbalanced sources if the "Phantom power" is ON which will be explained next.

In order to use a condenser, the "Phantom power" switch on the back of the mixer must be set to the "ON" position, which should be already in that position now. "Phantom power" is utilized with the first 8 XLR inputs (Channels 1-8) and cannot be switched ON or OFF individually. XLR stands for "Extra Long Run" (a circular plug with three prongs aligning in a triangular position).

CAUTION:

If a ribbon microphone (like the one David Letterman had on his show) or an unbalanced line (using only TWO of the three prongs of the plug) is also plugged into XLR inputs 1-8, do not switch "Phantom power" ON. This potentially will damage the microphone or audio output circuitry of the attached devices. If condensers as well as ribbon microphones and/or unbalanced line inputs are required to be connected to XLR Inputs 1-8 simultaneously, then use an external "Phantom power" supply for the condenser microphones.

The current configuration of inputs should be labeled below the input faders on the Mixer. If it is not labeled, the input should be available for use (e.g., CD, additional wireless microphone.). The SEL buttons are used for setting up each individual channel (See the Mixer's manual for details but don't need to konw about it now for basic operation). The ON buttons are equivalent to MUTE. The "20dB PAD switch" and "GAIN control" have already been preset by the Sound And Light Team (SALT) if the channel is being used and thus do not need adjustment. The "GAIN control" can be lower to avoid feedback or echoing if necessary. The usual setting is below or at mid-point of the dial. Therefore, the only things you may need to control are all the ON buttons and/or "Input channel faders" except the "RTN/SEND fader" which is the control for internal feedback usually fixed at between 20 to 40. The usual setting of an "Input channel fader" is 5 or above and try not to go below 0; otherwise, there will be echoing.

Note that the "2-track input jacks" (2TR IN) and "Stereo input jacks" (ST IN) are sharing the same input channel, but the "Stereo input jacks" has higher priority. In other words, "2-track input jacks" will be disable whenever the "Stereo input jacks" are plugged in.

Among the "LCD function buttons", the RECALL button is used to recall stored setup of all input channels and sources for a particular setting (use "PARAMETER wheel" to select after the button has been pressed). Do not store any setting unless you know what to do. Appendix B shows the console settings data stored as Scene Memory inside the Mixer. The METER and SEND4 buttons are used to select the control of the front big Main Speakers in the Sanctuary and the small Monitor Speakers above the Choir, respectively. Once the METER has been pressed, all the "Input channel faders" are input volume controls applied to the Main Speakers. Likewise, when the SEND4 is pressed, all the "Input channel faders" are input volume controls applied to the Monitor Speakers. Note that the "Stereo output fader" is used for both Main and Monitor Speakers at the same time.

Consult the Mixer's manual for the usage of all other buttons or inputs and outputs. Note that the current setting of the Mixer will be stored in a temporary buffer when its power is being turned off. That setting will be restored when it is powered on next time.

The Equalizer, Power Amplifiers and Speakers

Simply do NOT touch any buttons on the equalizer and power amplifiers except the ON/OFF switches unless you know what to do. The volume controls of the amplifiers are at the back of the amplifiers. The "QSC 850" is for the Main and Monitor Speakers while the "QSC 370" is for all the Ceiling Speakers outside the Sanctuary. Refer to Figure 2 for the location of all the speakers.

The ceiling speakers inside the Kitchen and Nursery have their own independent volume control mounted on the wall by the door, but the ceiling speakers in the Foyer do not. As a result, if concurrent worships are held in the Sanctuary and Fellowship Hall, all the ceiling speakers should be off by turning off the "QSC 370" power amplifier.

The Wireless Microphones

Make sure the battery in the transmitter is not low before giving it to the person who will use it. Usually, the green LED light on the transmitter should be "lighted" when its power is on. When only either yellow or red light is on, it indicates low battery. When battery is low, replace the battery (usually 9 Volts) immediately only if you know how to do it; otherwise, report to the SALT Leader or General Business Committee. Note that some equipment having only a single red LED that will light up momentarily when they turn on and go off immediately; this actually indicates that the battery is good.

When the preacher or announcer is using a lapel wireless microphone, make sure the pulpit microphone closed to him/her is off (mute). If an interpreter is standing next to him/her, leave the pulpit microphone closest to the interpreter on. Alternately, use another lapel wire or wireless microphone for the interpreter, then both the pulpit microphones must be mute. Remember to turn it back on when somebody else comes up to the pulpit and speak without a lapel wireless microphone. Do not curve or bend the flexible antenna attached to the transmitter of the lapel wireless microphone to avoid poor reception or damage to the antenna.

Currently, the gain of the wireless hand-held microphone system is small; therefore, remember to increase the gain on the mixer if necessary.

The Cassette Tape Deck - Marantz PMD510

The Bay (or Side) A (left-hand side) of the tape deck (mounted on the rack under the counter) is for RECORDING only while its Bay (Side) B (right-hand side) is for PLAYING only. If setting the deck in either two-side or continuously-repeat mode (NOT in one-side mode), output from the Mixer can be recordeded continuously on both sides of a cassette tape in Bay A without physically turning the tape around and the recording will be automatically stopped once both sides of the tape have been recorded. Tape in Bay B can be continuously playing for one or two sides, or continuously playing without stopping. During recording, pay attention to tape recording volume control which is on the right hand side of the panel next to the REC button. Monitoring the recording level (LED's); if it is below -10 db turn the volume control knob higher. For more details refer to the Deck's manual.

During Sunday worship, normally if possible and applicable, start recording right before the choir or special music performs and stop it after the sermon. Label and give the recorded tape either to the church secretary or Pastor.

Operating the Sound System

To operate the system, follow all or some of the steps as follows:
• Remove cover on Mixer if any.
• Turn on all power in the following sequence (From Signal Sources to Power Amplifier):
  
  A. (Optional) Cassette [mount on rack under counter]
  B. (Optional) Phono/Tuner/CD if any
  C. Wireless microphone(s) [Surge protector strip on or above counter]
  D. Mixer [Switch @ back right]
  E. Equalizer Q310 [mount on rack under counter]
  F. Power Amplifier USA 850 [mount on rack under counter]
  G. Power Amplifier USA 370 if desired [mount on rack under counter]

• Control Mixer as desired. Most normal levels are at "5" and few are at between "20" and "40". If desired, use RECALL button and "PARAMETER wheel" on the Mixer to select previously setup setting (e.g. SUNDAY01). See Section II of this Manual or the Mixer's manual for more details.
• When done, turn off power in reversed order of (2) and put cover back on the Mixer. That is, turning all the power amplifiers off first.

Some quick notes about operating the Mixer:
• Before any input plugging into or unplugging from the Mixer, either the input ON/Mute switch on the Mixer or the power amplifier must be OFF first. This is to avoid loud "booming" noise (current spike) which may damage the speakers.
  
• Turn off (mute) the choir microphone inputs if not in use to avoid picking up noise from the monitor speakers. Likewise, turn off the pulpit microphone inputs and/or other unused microphone inputs when the choir performs.
  
• If the podium/pulpit stand is to be removed (e.g., for wedding), disassemble both podium (long neck) microphones and cables and store them properly before the moving. There are two long white cardboard boxes inside the Sound Room for storing the microphones.

Notes to SALT Members

Main responsibility of the SALT is to set up and provide control to all the sound and lighting needs for regular and assigned church-related functions. During Sunday worship, if there is also English Worship being held in the Fellowship Hall, just make sure the sound system there is setting up correctly and working properly. Currently, the sound system is composed of a pair of speakers on speaker stand, a mixer-power amplifier and two dynamic microphones on microphone stand. Make sure the amplifier is plugged in through an external surge protector to the wall outlet. The plugs of all speaker cables are out of shape and thus please handle with care. The co-worker in the English Worship will provide the real-time control of the system.
• Provide control to the sound system in the Sanctuary is the major task of the team. There will be a schedule assigned and distributed ahead of time to each member. If there is any change, please notify the Team Leader immediately. An up-to-date schedule will also be posted inside the Sound Room.

• Normally, all the lights in the sanctuary are ON and in "HIGH" position during any activity. Don't forget the lights behind the stained glass (the cross above the Baptistry); remember to turn it off too when you leave. The light inside the Sound Room may be turned off during the activity if the little light attached to the power stripe on the wall is on. Report any light-out including the "Exit Sign" to the General Business Committee. FYI, all light fixtures exterior to the church building except the flood lights use either 60 or 75 Watts long-life or industrial-graded light bulbs. Interior use 60 or 75 W for fixtures on the walls, 100 W for ceiling and 150 W for all round pendents except the one in the Foyer which uses 100W.

• Right under and next to the Mixer there is an anti-static pad (gray color). Always remember to touch it by your bare hand before handling very sensitive equipment like the Mixer, especially during winter time and if you are wearing leather shoes. Electro-static is fatal to any electronic equipment.

• The sound you hear inside the Sound Room is softer than outside the Room. So, if you can hear the sound loud and clear inside the Room, the people in the front row in the Sanctuary must be suffering. Therefore, from time to time, you may need to stick your head outside the Sound Room to really feel the sound condition. A quick check on the mixer is to monitor the green LED's aligned vertically next to the LED panel. The normal range of number of green LED's lighted should be between 2 to 3. If four or more of them are constantly on implying the sound may be too loud, you have to stick your head outside the Room to double check it. Likewise, if only one or two are constantly on, sound may be too low.

• The PC inside the Sound Room may interfere with any wireless system signal. If the PC is not in use, make sure it is off including its monitor.

• There are a church extension telephone and a closed-circuit TV monitor inside the Sound Room. You may need to answer the phone especially during Sunday Worship. The closed-circuit cameras are currently monitoring the side entrance next to the Nursery and the foyer. To turn on the cameras, go to the Main Office. Power on the monitor located above the door of the Office (power switch is the first one on the left), and then press "A" to Auto Mode and "1" & "3" to switch on the two cameras. Monitoring the closed-circuit cameras during worship is optional but please do help answer the phone quick because the long ring of the phone will disturb the people at the back rows in the santuary.

• Please handle all the equipment with great care. Wire attached to a plug can easily be broken off if the wire is pulled during unplugging from the floor pocket or a microphone. Hold tight the plug (not the wire) during plugging in or out (of course, remember to mute its input to the Mixer or turn off the power amplifier first to avoid damage to the speaker). Do not bend the wire or drop the plug hard on the floor. When laying down the microphone, make sure it will not roll away and drop on the floor. Do not tap hard on the microphone head for sound testing, excess force will dent the grid of the microphone. All microphones after use must be put back to its pouch or box to protect it from dirt and dust. When changing battery to any equipment, always check the battery if it is deformed or damaged and do not use brute force to jam it into the compartment.

• Remember that it is your responsibility to instruct the user how to handle and operate the equipment such as the wireless microphones. The Shure wireless lapel mic is very expensive (>$400) and thus should be given to a user who is familiar with wireless microphone. Therefore, it should be limited to be used by our ministerial staff and experienced user. The other wireless lapel is Telex (<$300) can be used by an interpreter or a less experienced user if necessary. Make sure the user has returned the equipment at the end of the program, else you must chase after him/her for the equipment. When return the equipment to storage, always make sure it is power off and, if any, check the wind shield (gray foam ball) is still there because sometimes it may come loose and drop. Always remind the user not to bend or fold the antenna or any wire attached to the equipment; it may break the wire and render the whole system useless.

• All electronic equipment should be stored inside the Sound Room except microphone stands, some extra wires and equipment used inside the Fellowship Hall. Microphone stands can be found inside the Fellowship Hall or Room 118 (next to the piano). Extra wires and/or equipment used inside the Fellowship Hall can be found in the left-hand side closet inside the Fellowship Hall.

• There are a LCD projection panel and a computer/video projector stored under the counter inside the Sound Room. Only if you have already been trained to use these equipment, then you may help to set it up. You may need to read manual agian and must follow the instructions in order to avoid damaging the projectors since they are expensive and easy to break. Make sure it has been cool down after use before putting it back into the carry case or bag, especially the computer/video projector. The excessive heat will damage the projector lamp which is current priced at $395. Note that the building including the Sound Room is protected by 24-hour monitored security alarm system and has Closed-Circuit Cameras.

• During Sunday worship, the offering plates are usually stored inside the Sound Room after the offertory. As soon as the usher hands the plates to you, put them inside the gray zipper bag which is normally put on the top of the white plastic shelf behind the chair. You do not have to zip it completely close since the bag is a little bit smaller than the plates, especially when there are a lot of offerings. If the zipper bag is not there, use a plastic bag which may be found below the shelf. Hand them over only to the member of the Finance Committee right after the worship. Usually they will come over to get it right after the sermon.
