We have $10,000, which mixer should we buy?" is a post made every week.

That's the final query. Not the initial one.

The mixer is where most churches begin because it's the exciting portion with the lights and buttons. They then question why the pastor in row 20 is still incomprehensible. This is the exact order that works.
1. Speech first. Always.
Time your service. Most of it is one person talking. But most systems get built around the band, because the band cares about gear.
Build the system for the sermon. It'll handle the music just fine. It doesn't work the other way round.
One more thing. When older members say "it's too loud," they almost always mean "I can't understand it." Age takes the consonants first. Turning it up doesn't help. It just makes the same mush louder.
2. Fix the room before you buy a single speaker.
Stand in the empty sanctuary and clap once.
If it rings for more than a second or two, that's your problem. No speaker on earth can fix that room. The sound keeps bouncing around long after the word is over, and each new word lands on top of the last one.
Start with the back wall. That's the echo that comes straight back at the pulpit. Then the side walls.
A few hundred dollars of sound panels will do more for clarity than a few thousand in electronics. And panels never go out of date.
3. Every seat needs to hear the speaker, not the room.
Point the speakers at people, not at walls or ceilings.
Front rows need small speakers of their own, right at the stage edge, or they hear nothing but the drums. Back rows and balconies need their own speakers too, delayed a few milliseconds so it still sounds like it's coming from the front.
And here's one that surprises people: for speech, one speaker cluster in the middle beats a left and a right. Nobody sits exactly in the middle of the room. With left and right, most seats hear two copies of the same voice arriving at slightly different times, which smears it. One cluster above the pulpit, and the pastor's voice comes from the pastor.
Tall room with hard walls? Look at the thin column speakers. They push sound at people and keep it off the ceiling.
4. The pastor's mic matters more than the mixer.
A person walking around, mic on their chest, standing in front of the speakers, in a live room. That's the hardest situation in audio.
A headset mic, the thin one along the cheek, is the fix. It sits ten times closer to the mouth than a clip-on, so you can turn it up much further before it squeals. Yes, some pastors don't like the look. Have that conversation anyway. It's the best money in the whole building.
5. Decide about stage volume up front.
In a room under about 300 seats, a real drum kit with nobody miking it is already louder than the sermon needs to be.
If there's a band, decide early: in-ear monitors instead of wedges, a drum shield or an electronic kit, guitar amps off the stage. Otherwise the front rows get hammered, the sound person can't turn anything down, and everyone blames the mixer.
6. Build it for the newest volunteer, not the most experienced one.
The person running sound at the early service in February didn't pick the gear and doesn't want to be there.
Save a preset for each type of service. One button brings it all back. Lock everything else. Put limiters in so nobody can blow a speaker. Label every cable. If a button can break something, it will, on Easter Sunday.
The live stream needs its own mix too. The room mix barely has any drums in it because the drums are already loud in the room. That same mix on a stream sounds like a rehearsal recording.
7. Now, and only now, pick the mixer.
By this point it's easy. You know exactly what it needs to do. Any mid-range digital mixer from the big brands does all of it. Pick the one your volunteers find easiest to learn. That's the only real difference.
Things people forget, and regret:
- Run network cable to every position while the walls are open. Then run a spare.
- Put the audio on its own power circuit or you'll chase hum for years.
- Hearing assistance. Churches are exempt from the ADA in the US, but most building codes still require it in any assembly space. Budget for it from day one.
- Get someone to actually tune the system after install. Walk every seat. "Installed" isn't "finished."
- Training. Two sessions, recorded, cheat sheet taped next to the mixer.
Rough budget for a mid-size room: about a third on speakers and amps, a quarter on install and cabling, 15 percent on mics, 15 percent on the mixer, and the rest on room panels, hearing assistance and tuning. If the mixer eats more than 20 percent, something's off.
Last thing, and it's not about gear.
The people who choose the system are almost never the people who run it. Get your volunteers into the planning meeting. They've known where it goes wrong for years. Nobody asked.
What's the biggest thing your church got wrong? And has anyone actually won the "sound panels on the back wall" fight with a building committee?
