Meetinghouse Webcast Audio
All content on this page is moving to LDS Help Center under the Meetinghouse Technology topic. This page was supposed to be deleted at the end of October 2012.
Audio systems in meetinghouses vary around the world. Your meetinghouse audio system with its accompanying jacks and available cables and adapters will depend on a variety of factors including: location, age of building, building design, and decisions made by your local facilities group and contractors. The variations make it difficult to define exactly what you will experience as you set up the audio for your webcast. This document will provide you with helpful insights but your ultimate audio solution may end up being unique to the building you are working in.

Here are the types of audio equipment you need for your webcast:
- Audio source
You either need an output from your meetinghouse audio system or a microphone that can provide audio directly to your webcast solution.
- Audio mixer
It is strongly recommended that you use an audio mixer at the location sending the webcast. This allows you to easily adjust the volume of the webcast before and during the webcast. It is very valuable when the volume of your meeting participants varies. The audio mixer should be placed in front of the webcasting device to allow you to adjust the volume before it is captured, compressed and relayed over the Internet.
- Mini amp with phantom power
If you are inputing audio from a microphone independent of your meetinghouse audio system, you need a mini amp with phantom power in order to boost your audio before it enters the webcasting device. You do not need a mini amp if you are using a good audio mixer.
- Audio cables and adapters
At the sending site, you need to connect the audio from your audio source (meetinghouse audio system or microphone) to your audio mixer and then from your audio mixer to your webcast device. At the receiving location, you need to connect the audio from your receiving device to your meetinghouse audio system. The length, size and type of connecting cables and adapters varies depending on factors such as: design of audio system, location of meetinghouse audio jacks and webcast devices, and audio mixer configurations.

Generally, there are four options for capturing audio in the meetinghouse. Three of these options use the chapel audio system, and one uses a separate microphone. Each involves different setup instructions. Use the option that best fits your situation.
- Option A: Use the clerk’s desk, sacrament table, or pulpit
- Option B: Use the meetinghouse library (or satellite closet)
- Option C: Use a second microphone on the pulpit
- Option D: Use an existing hearing impaired receiver
Warning: Do not plug the chapel speakers or amplifiers directly into the Webcast Communicator. They operate at different voltages. This will damage the components in the Webcast Communicator and require you to purchase a replacement Webcast Communicator.
Option A: Use the clerk’s desk, sacrament table, or pulpit
This option requires a cable to run from the clerk’s desk, sacrament table, or pulpit to the camera at the back of the chapel. This cable is either the video cable connecting to the Webcast Communicator or computer, or the audio cable from the “record out” port. The Webcast Communicator or computer can be placed near the clerk’s table, the sacrament table, or at the rear of the chapel.
- Locate the “record out” mini port found near the clerks’ desk or under the sacrament table, or find the “sound system out” at the side of the pulpit.
- Connect the “audio in” on the Webcast Communicator or computer to the “record out” mini jack with the Mini-to-Mini or Mini-to-RCA adapter.
Option B: Use the meetinghouse library (or satellite closet)
If the meetinghouse library has a satellite panel, set up your Webcast Communicator or computer there since it is out of the chapel (where there is less foot traffic). The location is also close to components you will need to connect to the Webcast Communicator or computer. Although this is the most complex option, it provides the best webcast production quality.
- Open the door to the satellite equipment rack.
- Locate the modulator that is used for chapel overflow. This is usually the highest channel number in the US. For example, if your rack has a channel 3 and a channel 10, and if channel 3 displays a picture while channel 10 does not, then the chapel output is probably on channel 10. The correct channel will show a picture when the camera is connected to the video input jack (located at the back of the chapel).
- Open the back of the rack and find the modulator for the back of the chapel overflow. (There should be three cables: RF out, video in, and audio in.)
- Unplug the “audio in” cable from the back of the chapel overflow modulator and plug it into one of the female connectors on the Y adapter.
- Plug the male connector from the Y adapter into the back of the chapel overflow modulator.
- Plug the Mini-to-RCA adapter (side with the male RCA) into the last connector on the Y adapter.
- Plug the Mini-to-RCA adapter (side with the 1/8 inch) into the “audio in” on the Webcast Communicator or computer.
For details on using a mixer to improve audio quality, see Using a mixer between the Communicator and the meetinghouse audio system.
Option C: Use a second microphone on the pulpit
This option uses a separate microphone instead of the chapel audio system.
- Mount alternate microphone near the pulpit or speaking location.
- Connect a microphone cable to the alternate microphone.
- Plug the microphone cable into the power adapter.
- Run the microphone cable to the Meetinghouse Webcast Communicator or computer.
- Plug the XLR-to-Mini adapter into the audio mixer or the microphone phantom power supply and Mini Amp
- Connect the Mini Amp with the Webcast Communicator or computer using a 1/4 inch to 1/8 inch audio cable connector.
NOTE: Cable should plug into the audio MIC-In port of the Webcast Communicator.
Option D: Use an existing hearing impaired receiver
This option works with wired or wireless amplifiers for the hearing impaired (for example, Comtek in the US). The sound will have less bass and a higher pitch because of the sound changes required to assist the hearing impaired. You may need to turn down the volume on the Webcast Communicator or computer to produce a more normal sound.
- Locate a receiver for the hearing impaired. Use an extra receiver if you have members who regularly use the system.
- Install a new battery to ensure the power lasts throughout the meeting.
- Connect the “audio in” on the Webcast Communicator or computer to the hearing impaired receiver with the Mini-to-Mini adapter.
- Receiver should automatically turn on when headphones are plugged into the port.
Audio setup at receiving meetinghouse
Connect the Meetinghouse Webcast Receiver or computer audio output to the chapel sound system by using an EJ-8 or EJ-10 multi-adapter input device (crab):
- Connect the cable from the EJ-8 or EJ-10 crab to the Webcast Receiver (use the “audio out” port marked with headset icon) or computer headset output port.
- Connect the EJ-8 or EJ-10 crab microphone output cable to the building microphone input jack.
NOTE: To remove distortion in the line, use the volume control knob on the crab. To adjust the volume in the chapel, use the pulpit volume control knob.
Test your audio
It's essential that you test your audio in advance of your event. Incorporate the same type of audio into your test event that you expect to experience in your actual event. If you expect your meeting to include a musical number, a loud speaker, a soft speaker, a choir singing, and a violin solo--test all these audio inputs in advance of your event.
Manage your event
Once your webcast begins, it becomes more challenging to adjust audio levels. Meetinghouse Webcast is designed to buffer the webcast--this builds in an approximately one minute delay between the sending and receiving location. If audio needs to be adjusted during the event, the receiving location won't hear the adjustment until approximately a minute later. Both the Webcast Communicator and in the Webcast Software have controls for adjusting audio. But these controls may not allow enough adjustment to get the audio levels right. Running your audio through a separate audio mixer before it reaches the sending device will provide the most flexibility for adjusting audio levels.
If the audio level is acceptable at some but not all viewing locations, you may want to try adjusting the audio just at the receiving locations encountering issues. If viewing the webcast in the chapel of a receiving meetinghouse, try adjusting the audio using the volume controls located near the podium. When using a computer to view the webcast, you can also adjust the volume controls on the computer. You also have an adjustment option on the EJ-8 or EJ-10 multi-adapter input device (CRAB) that the audio runs through from the Webcast Receiver or computer to the chapel audio system.
