- Using only the pulpit microphone: Great for talks. However choirs, soloists and prelude may not be loud enough in receiving locations unless addition microphones are used and a way to control them is employed. Plugging additional microphones into the building sound system to cover the choir will most often increase feedback and decrease sound quality if they are not turned off by the sound system (noise gate) when not in use. If a choir is really large, you may get by using only the pulpit microphone. However, the pulpit microphone is insufficient for the following situations:
- Prelude music: A pulpit mic will amplify the ambient noise from the congregation in the chapel, so the receiving locations actually hear more talking and conversations than what is actually there. Increasing the gain for more prelude music only results in increasing the amount of conversation noise. An ideal solution to this is to tap off the organ (line out) or mic the organ speaker or piano and feed the signal into a separate audio mixer.
- Soloists: Musical instruments and soloists are usually much quieter than the overall volume level of the choir and cannot be adequately amplified by the pulpit microphone. Placing microphones in close proximity to the source is an ideal solution.
- Multiple cameras: A single camera is all you need for a conference, but distracting movements and the lack of skill of a camera operator can result in a poor viewing experience by hundreds of people. Adding an additional camera increases the professionalism of conference. For example, using more than one camera can:
- Allow one of the cameras to be positioned (frame, composition, focus) while the other is broadcast to the receiving locations
- Break up the boredom and monotony of a single camera angle
- Bring viewer closer to the experience of being present. For example, cutting to a wide shot as soon as the speaker ends his talk to view see what is going on in the chapel as speakers move to and from the pulpit
- Camera angles might be moved in a distracting way between shots (i.e. using camera presets on robotic cameras or an inexperienced camera operator). Simply cutting to a different camera hides any distracting movements.
- EVI-D70: This Sony camera is versatile, small, can be operated right-side-up or up-side-down, has an appropriate zoom ration for chapels, has very good picture quality (SD) and can be completely controlled remotely. By eliminating a camera operator standing at the camera, it can literally be hidden from the congregation. Every function of the camera can be operated remotely including pan, tilt, zoom, focus, iris and color balance. The price is very affordable (as low as $300). As far as high definition, every link in the transmission must to be HD capable in order to have HD at the other end (camera, cables, video mixer, capture device, adequate upload and download speeds, receiving device, projector, TVs, etc.) Simply adding an HD camera will not result in an HD picture. The intent of the EVI-D70 is remote operation at an affordable price. Obviously the prices of HD products will be more affordable in the future, but as of right now standard definition is much more affordable.
Conclusion: Adding and operating an independent audio mixer for pulpit audio, a couple of microphones for the choir and tapping audio from the organ solve most conference audio problems. Our task is to deliver picture and sound to hundreds of people. Increasing our professionalism to provide the best viewing experience possible with our limited talent and resources without causing distractions will tend to increase the Spirit and a pleasureable viewing experience.
Personal note. For years, several stakes STS and presidencies in my area had been hesitant about adding this kind of equipment, but after a single demonstration of our stake's set up, they were convinced that it is affordable and worth the effort to increase the professionalism of their conferences. Actually seeing a set up and the results can be impressive. If you’re interested in a demonstration, PLEASE contact me with a personal message. I’d be more than happy to help in any way I can.
