Why are we spending so much money on wireless microphones?


We literally had to wait for a herd of goats to move so we could park the jeep. We use the phrase "middle of nowhere" pretty liberally in the US; this was a three-hour drive into the scrub grass plains of the southern Congo, right on the border of Zambia. We had split our team into three groups to visit as many churches as we could on Sunday morning. I drew the straw for the wilderness excursion, to a dirt floor mud brick thatched roof hut church where I spoke to a crowd of about 40. Noisy packs of kids and chickens rushed in and out through the open doorways as if to punctuate my better points. Truly one of the better church services I've ever been to. 

    The really odd thing about that service wasn’t the wild atmosphere: that’s Africa. What was weird was seeing a brand new, name brand wireless microphone at the service. The horn on the one speaker they had was blown (the trademark Africa sound you’ve heard in 100 movies), and the whole PA was being run off a car battery, but they had sunk 90% of their sound budget into a microphone that costs twice as much in Africa as it does in the states (if you can even find one).

    There’s a whole thing here about how we are influenced, how we watch people do things and then think if we copy them (externals) we will have the same (spiritual) results, and how we are often totally unaware of how we are being influenced in this way, but this is a tech thing, so…

    Why are we spending so much money on wireless microphones? 

A wired SM58 will work and sound fine when your great grandkids use it. If one of them had been buried with King Tut you could blow the dust off and plug it in. I paid $30 for a used one on Reverb last week.

Here’s what you need to know about wireless microphones:

  • Wireless microphones are 2-5 times as expensive as their wired counterparts. 
  • Wireless microphones do not sound as good as their wired counterparts. I might even go so far as to say they never will, since the sound has to go through a (degradation) process to be transmitted. There are people that know a lot more than me about this for sure, but in my experience (and that of every great engineer I know) no one prefers a wireless mic based on its sound quality. 
  • Wireless microphones are technology with a shelf life. They have more parts: digital, computer parts, and will be outdated or quit working at some point. (Or the FCC will take your frequency, whichever comes first.)
  • Wireless microphones require constant basic maintenance. That battery will always die mid-set or mid-sermon. Aren’t those moments great? 

    In my work as a sound consultant, I often go into smaller churches with $30 hi hats, $100 guitars, and $3000 worth of wireless microphones. (I don’t want to come right out and say you spent that money because you saw someone that looked cool holding one on YouTube, but…did you?)

    People sometimes look at me like I have three heads when my suggestion for how to fund their basic audio needs is to sell 5 of their 7 wireless microphones. In 3 of the last 4 churches I’ve worked with that’s exactly what we’ve done, because $800-1500 will solve most of the problems that small churches are experiencing, and most churches that tell me they have no money have those mics in a drawer in the booth.

    When it comes to audio budgeting we act like microphone cables are the thing preventing life transformation from happening in our churches. I get it, cables are annoying. Get a wireless for your pastor. Does your worship leader play guitar or keyboard? Please explain the actual benefit of a wireless mic in that situation. 

    Recently I saw an ad for a famous mic company with a big-name worship leader in it. He was holding a super-slick wireless, and sporting super-hip IEMs and the tagline read: “Your message is important. Make sure it’s heard clearly.” I laughed so hard I think the staff was considering escorting me out of Barnes and Noble.
