Counting mixer channels
Start with every source that needs its own fader: vocal microphones, each drum mic, guitar amps or DIs, bass, keyboards, acoustic instruments and playback devices. Mono sources take one channel; stereo sources such as keyboards and laptops take two inputs (or one stereo channel). Then add spare channels for guests, extra mics and backup wireless – running out of inputs mid-show is a classic problem.
Typical setups
| Setup | Inputs | Monitor mixes | Mixer |
|---|
| Singer-songwriter / small café | 3 – 6 | 1 | 6 – 8 channel analog |
| Four-piece band, basic drums | 10 – 14 | 2 – 3 | 12 – 16 channel |
| Band with full drum mics & keys | 18 – 24 | 4 – 6 | 24-channel digital |
| Church worship team | 16 – 32 | 4 – 8 (in-ears) | 24 – 32 channel digital |
| Corporate / conference | 6 – 16 (wireless) | 0 – 2 | Compact digital |
Aux sends and monitor mixes
Each separate monitor mix – a wedge or in-ear pack with its own balance – needs an aux send. Effects such as reverb and delay usually use aux sends too. Small analog mixers often have 2 – 4 auxes; digital mixers typically offer 6 – 16 mix buses, and many let performers adjust their own monitor mixes from a phone or tablet.
Analog or digital?
- Analog: simple, hands-on, no menus. Great for small, unchanging setups. Effects and EQ are limited; outboard gear adds cost.
- Digital: built-in EQ, compression, gates and effects on every channel; saved scenes for each band or service; remote control and multitrack recording over USB.
- Stage boxes: digital mixers with network stage boxes replace thick analog snakes with one cable.
Other things to check
- Number of microphone preamps (not just "channels").
- Phantom power on all mic inputs for condenser mics.
- Outputs for mains, subwoofers and recording/streaming.
- USB audio interface for recording and livestreaming.
- Expansion options if your band or church grows.
Frequently asked questions
How many channels does a band mixer need?
A typical four- or five-piece band with a few drum mics needs 16 – 24 inputs plus spares.
What is an aux send?
An output that lets you send an individual mix of channels to a monitor or effects processor.
Is a digital mixer better than analog?
For many inputs and monitor mixes, yes – digital mixers include processing, scenes and remote control. Analog is simpler for small fixed setups.
How many channels for church sound?
Small churches often need 16 – 24 inputs; worship teams with full bands and choirs may need 32 or more.
Do stereo keyboards need two channels?
Yes, a stereo keyboard uses two inputs or one stereo channel.
About ChannelCount
ChannelCount is an independent, free planning calculator for bands, churches, schools and event venues choosing live sound mixers. We are not affiliated with any mixer manufacturer.
Every formula on this page runs entirely in your web browser. The numbers you type are never uploaded, stored or shared. Our goal is simple: give you an honest starting point so you can compare product specifications with confidence and avoid paying for capacity you do not need – or buying something too small to do the job.
The methodology combines widely published engineering rules of thumb, manufacturer data sheets and the electrical code practices that installers use every day. We review the assumptions regularly and update the calculator when typical product specifications change.
