Miking Those Overlooked Areas of Your Facility
By: Gene Houck When equipping your church with the proper AV products, sometimes microphones are the last items to be considered. Yet, when we fully appreciate that the microphone is the first link in the sound chain, we understand how important the right microphone for the right application is. There are many applications that need microphones for either sound reinforcement and/or recording. We generally know of some of the microphone selections available for pastors, worship leaders, and musicians, but what about some of the areas that don't get much attention or get overlooked entirely? Let's take a moment and examine a few of them. Ambient Microphones Ambient microphones are utilized to bring in more of a natural room sound. You can blend them into your "in-ear" mix as well as a "recorded" pastoral message mix. In-ear monitors are fed a mix from the house or monitor mixing board. Consider that when a performer uses a floor monitor wedge as opposed to an in-ear system, they still are hearing the room as well as the floor monitor. Conversely, if using in-ear monitors without an ambient microphone mix, the overall sound can be very sterile and not give the performer a "natural" sound with which to work. Blending in an ambient microphone mix can replicate what our ears hear in a room. Next, have you ever listened to a recorded pastor's message where the pastor delivers a joke and you laughed, but it sounds like no one else in the congregation laughed? It could have been a bad joke, but odds are that you were listening to a recorded message that did not have the added benefit of ambient microphones. So what mics do you use, how many mics do you use, and how do you place and position them? First of all, since you are trying to capture a large area from a distance, you need a microphone with very good sensitivity. Typically, the microphones that you will find in a house of worship are either "dynamic" microphones or "condenser" microphones. Since condenser microphones have much greater sensitivity, they can cover more range or area, and they are the microphones you need. Many condenser microphones also are smaller and can have a lower profile when used. Condenser microphones will require phantom power from your mixing console. For most sanctuaries, you will need two condenser microphones. What you are trying to do is pick up the congregation and not what is coming out of the main speakers. Cory Maus is the technical director for Crossroads Church in Vancouver, Washington, and their sanctuary holds 2,000 people. Since avoidance of picking up the main speakers is the desired effect, sometimes a "shotgun" condenser can be used. Shotgun microphones are commonly used on TV and film sets, as well as for field recordings. They are more focused and directional and provide a narrower angle of acceptance that isolates the subject's sound from unwanted "off-axis" sounds. This results from placing the element inside a tube with slots cut along the side; wave-cancellation eliminates most of the off-axis noise. The way these microphones capture sound from a distance is similar to holding a paper towel tube up to your ear. The longer the tube, the more focused the sound will be. Terry Rhodes, a senior systems design engineer with Pace Communications Group out of Easley, South Carolina, came up with a very inventive way to place ambient mics in a house of worship. He said, "One of the churches I was working with had some nice indoor plants on both sides of the platform. I got the idea that if I hid two shotgun mics in two of the plants and pointed them out toward the congregation, it could be an alternative to hanging the mics, and it would also be the most discreet solution. It worked great! The mics (or plants) are positioned 8 to 10 feet from the edge of the platform. They are on small mic stands like you would use for a kick drum. So, the mics are about 16 inches off the ground and are pointed slightly up to go over the heads of the first few rows." Sometimes churches will try to hang ambient mics alongside or within speaker clusters that are hung. Although this can be done (and it hides the microphones well), it can have some unexpected and unpleasant consequences. All speakers have lobing patterns (dispersion characteristics). Incorrect mic placement can pick up and induce feedback. If seeking to place ambient mics near speaker clusters, I suggest consulting with a systems engineer who has the expertise and equipment to make sure you get optimal placement. Baptistry Microphones Since the accident, many churches have been using wireless microphones for baptism ceremonies. Wireless microphone transmitters utilize a battery that does not cause electric shock issues. Usually the pastor or person administering the baptism has a lapel or headset microphone. The wireless body pack is sealed in a zip-top plastic bag for water protection. While this is safe, there are two challenges. One, you can usually only hear the pastor and not the testimony or witness of the person being baptized. Two, no matter how hard you try, sometimes mics and transmitters get wet and can be damaged. You can also use a handheld wireless transmitter. In some ways, this is a better choice because the person being baptized can also be heard. However, make sure that when the mic is laid down next to the immersion pool (at the time of immersion) it does not fall back into the pool. To avoid the above challenges, I usually recommend hanging a condenser microphone with good sensitivity and output. In the same fashion, as mentioned in the "ambient microphone" section, a shotgun microphone can be a great solution. In the case of a baptistry, you want to hang the microphone as close as possible. A small hanging condenser choir microphone will do the job. Communicating with the Sound Engineer The microphone of choice is a handheld dynamic with a switch. The mic is set into a desktop mic stand. The channel can, of course, be muted at the board, but it is a nice convenience to simply turn the mic switch on and off as needed. This mic can be an inexpensive microphone since it is only used for speech between the platform and engineer. In fact, this problem is solved for less than $50! The mic is folded into the monitor mix so that the musicians and singers can hear what the engineer is saying. I hope these ideas help you make the proper microphone selection and placement so that all concerned hear things better (and you are safe while doing so).
