How to Choose a Church Mixing Console
Quick answer
Count every input, add about 25 percent for growth, then round up to a size that is actually sold. A church with 16 inputs needs a 24 channel console, not a 16 channel one, because a desk with no spare channels gets replaced within about two years.
Console selection is the decision churches enjoy most and get wrong most often, because it is the visible purchase and because the specification that matters is boring. The right console is decided by an input list and by who operates it, not by channel count bragging rights or brand loyalty. A 32 channel desk in a church with 12 inputs is money that should have gone into loudspeakers.
There are really only three questions. How many inputs do you have and will have. Do your operators change from week to week. And does the room need mixes for monitors, a livestream and an overflow space, or just a house mix. Answer those three and the field narrows to a handful of consoles, and the mixer channel calculator will do the counting.

Build the input list first
An input list is every source that needs a channel, written down. For a typical church that means the preaching microphone, a lectern or pulpit microphone, two to four worship vocals, acoustic guitar, electric guitar, bass, keyboard, drums, choir microphones, playback from a computer, and a return from the livestream system if there is one.
Two rules cause almost all under-counting. Stereo sources take two channels, so a stereo keyboard is two inputs and playback from a laptop is two more. And a drum kit is not one input: a five piece kit with overheads is seven. A church that writes "drums, 1" on its list will be short six channels on the first Sunday the full band plays.
Then add growth. A 25 percent margin is the working convention and it is not generosity, it is realism about how churches change: a new instrument, a second campus feed, a hearing assistance send, an extra vocal. Round the result up to 16, 24, 32 or 40, because those are the sizes consoles are sold in. A template to work from is at the input list template.
Console size by church size
These are the input counts and console sizes the calculators produce for four common sanctuary sizes.
A 250 seat church typically runs 16 inputs and should buy a 24 channel console, while a 1,000 seat church runs about 32 inputs and needs 40 channels.
| Seats | Typical inputs | With 25 percent growth | Console size to buy | Monitor mixes |
|---|---|---|---|---|
| 100 | 10 | 13 | 16 channel | 2 |
| 250 | 16 | 20 | 24 channel | 4 |
| 500 | 24 | 30 | 32 channel | 6 |
| 1,000 | 32 | 40 | 40 channel | 8 |
Input counts assume a typical blended or contemporary service with a band, choir microphones and a livestream feed. A church with an orchestra, a large choir or multiple campuses will exceed these and should build its own list rather than use the table.
Digital or analog, and why recall usually settles it
The honest technical answer is that a good analog console and a good digital console both sound fine, and the choice is about workflow. The decisive feature for most churches is scene recall. A digital console stores every setting as a named scene, so the volunteer arriving on a rotating rota starts from the settings that worked last week rather than from whatever the last person left behind. In a church staffed by volunteers, that is worth more than any specification on the audio path.
Digital also brings processing that would cost thousands separately: a gate, a compressor and a parametric equaliser on every channel, plus effects and a system processor. The Behringer X32 at $1,999.00 is the reference point here, and the XR18 at $509.00 gives much of the same processing in a rack box controlled by a tablet for far less. The full argument is at digital versus analog mixers for church.
Analog still wins in two situations. A very small church with six inputs and one operator who understands the desk does not need recall, and the Yamaha MG12XU at $425.00 is a perfectly good answer. And a church whose volunteers are genuinely intimidated by menus may get more consistent results from knobs they can see. Be honest about which of those describes your team.
Surface, rack or tablet
A third decision that churches meet late. A traditional surface console has physical faders and lives at a mix position in the room, which is where mixing should happen because that is where the congregation sits. A rack mixer such as the X32 Rack at $979.99 has the same processing with no surface, controlled by a tablet, which frees the floor space a mix position occupies and lets the operator walk the room while mixing.
The tablet approach is genuinely liberating and has two costs worth stating. A tablet that loses its Wi-Fi connection mid-service leaves the operator with no control at all, so the wireless network becomes part of the sound system and has to be treated that way. And a rotating volunteer team often finds physical faders faster to learn than a touchscreen. The trade-offs are at rack mixer versus console and tablet controlled versus surface mixer.
How to choose a console in seven steps
- Write the input list for the largest service you run. Not the average Sunday, the Christmas service or the one with the full band and the choir. Count stereo sources twice and count every drum microphone separately. This is the number the whole decision rests on, and under-counting here is the most common console buying mistake.
- Add 25 percent and round up to a size that is sold. Consoles come in 8, 12, 16, 18, 24, 32, 40 and 48 channel sizes. Rounding up to the next real size costs far less at purchase than replacing a desk that ran out of channels. A 16 input church buys 24 channels.
- Count the output mixes you need, not just the inputs. House mix, monitor mixes for the platform, a livestream feed that needs its own balance, an overflow room, a hearing assistance send and a recording feed are all separate buses. Churches size consoles by inputs and then discover they have run out of auxiliary sends, which is just as limiting.
- Decide whether you need scene recall. If the person mixing changes from week to week, the answer is yes and that points at digital. If one trained operator mixes every service, recall matters much less. Be realistic about your rota rather than aspirational about your volunteers.
- Choose the control surface format. A surface at a mix position, a rack unit driven by a tablet, or a compact desk with both. Consider where the operator physically needs to be, what floor space you can give up, and how reliable the building Wi-Fi is if a tablet is in the signal path.
- Check the stage box and cabling implications. A digital console with a stage box such as the S16 replaces a heavy copper snake with one network cable, which changes the installation cost considerably. Confirm the console and stage box speak the same protocol and that the cable run is shielded Cat6 rather than whatever is in the cupboard.
- Budget training time alongside the purchase. A digital console delivers its benefit only if the team can drive it. Plan at least one training session and one full rehearsal before the first service, and build a locked default scene that a volunteer can always return to when something has been changed and nobody knows what.
What not to spend money on
Channel count you will never use. A 32 channel desk in a 12 input church is roughly the price of a serious loudspeaker upgrade, and the loudspeakers are what the congregation hears. Buy the size the list calls for with growth, and put the difference where it changes the sound.
Onboard effects you will not use either. Reverb and delay on a worship vocal are useful; the other forty presets are not a reason to choose a console. And outboard processing that duplicates what a digital console already does: a church buying a digital desk does not also need an outboard gate and compressor, because it has one on every channel already. That money belongs in the loudspeaker or wireless line, which is covered at church AV upgrade priorities.

Frequently asked questions
How many channels does a church mixer need?
Count your inputs, counting stereo sources twice and every drum microphone individually, then add about 25 percent and round up to a size that is sold. A typical 250 seat church with a band, choir microphones and a livestream feed runs about 16 inputs, which means a 24 channel console. Building your own list is far more reliable than any rule of thumb.
Is a digital mixer worth it for a small church?
Usually yes, for scene recall rather than sound quality. If your operators rotate, starting every service from saved settings that worked rather than from whatever was left behind is the single biggest improvement available. Digital also includes per channel dynamics and equalisation that would cost thousands as outboard gear, which changes the value calculation considerably.
Do we need a mixing console at the back of the room?
The mix should be judged from where the congregation sits, so a mix position in the room is ideal and a booth behind glass is the worst case. A tablet controlled rack mixer solves this differently by letting the operator walk the room. What does not work is mixing from the side of the platform, where the operator hears the stage rather than the system.
How many auxiliary sends does a church need?
One per monitor mix, plus a separate send for the livestream, one for any overflow room, one for hearing assistance and one for recording if it needs a different balance. A church with four monitor mixes and a stream therefore needs at least six, and running out of auxiliary sends is as limiting as running out of input channels.
Can one console feed both the room and the livestream?
Yes, and it must not simply send a copy of the house mix. The room mix relies on acoustic sound from the platform that a microphone feed never captures, so a stream taken from the main output arrives thin and unbalanced. Use a separate bus with its own balance, which is why aux send count matters at purchase.
