If you’ve ever stepped behind a mixing console at church and thought, “I have no idea what half of these knobs do,” you’re not alone.

Church audio can feel overwhelming. There are gain controls, EQs, compressors, gates, aux sends, buses, effects, and dozens—or sometimes hundreds—of channels and settings staring back at you.

But good audio mixing isn’t about knowing how to use every feature on the console.

It’s about understanding a few fundamental concepts and learning how to listen.

That’s why I created FOH Audio Engineer 101, a free training course designed to give church audio volunteers a practical foundation for mixing live sound.

And to go along with the course, we created a downloadable Audio Mixing Cheat Sheet that you can keep at the console as a quick reference.

The Goal Isn’t a Perfect Mix

At Enhance AVL, we say:

Technology should enhance, not distract.

That applies directly to audio.

When someone is speaking, people shouldn’t be struggling to understand the words. When the worship team is playing, the congregation shouldn’t be distracted by harsh vocals, muddy instruments, feedback, or wildly inconsistent levels.

The technology should disappear into the experience.

A good audio engineer helps make that happen.

Start With Signal Flow

Before worrying about EQ or compression, you need to understand where the audio is going.

At its simplest:

Source → Input → Gain → Processing → Routing → Fader → Output

The exact signal path varies depending on the console, but understanding this basic flow makes troubleshooting dramatically easier.

If you don’t have audio, instead of randomly pushing buttons, you can start following the signal.

Is it reaching the input?

Is the gain set correctly?

Is the channel muted?

Is it routed to the right output?

Is the fader up?

Once you understand signal flow, the console becomes much less intimidating.

Gain Comes Before Mixing

One of the most important skills for a new audio engineer is learning how to set gain correctly.

Have the musician or speaker perform at approximately the level they’ll actually use during the service. Then set the input gain while listening and watching the meter.

You want a healthy signal without getting anywhere near digital clipping.

Our cheat sheet uses -12 dBFS as a practical reference point while leaving headroom for peaks, rather than trying to push every channel toward 0 dBFS. Enhanced-AVL-Audio-Mixing-Cheat…

Remember:

0 dBFS is the ceiling, not the goal.

EQ: Listen First

EQ is probably one of the areas where new engineers are most tempted to look for a preset.

“What frequency should I cut on a vocal?”

“What EQ should I use on a kick drum?”

There are useful starting points, but there isn’t one EQ curve that works everywhere.

Different microphones, singers, instruments, rooms, PA systems, and even microphone placement change what you’re hearing.

That’s why the first instruction on our cheat sheet is:

Listen first.

For example, roughly 250–500 Hz is an area where muddiness can often build up, while the 2–6 kHz region contributes significantly to clarity and bite. The sheet also provides starting ranges for kick, snare, bass, voice, acoustic guitar, keys, and cymbals. Enhanced-AVL-Audio-Mixing-Cheat… Enhanced-AVL-Audio-Mixing-Cheat…

Use those frequencies to help you know where to listen, not what you automatically need to boost or cut.

Don’t Forget the High-Pass Filter

The high-pass filter—or HPF—is one of the simplest and most useful tools on the console.

It removes low-frequency information below a selected point.

On sources that don’t need significant low-frequency content, this can help clean up stage noise, handling noise, HVAC rumble, and unnecessary low-end energy.

A simple approach is:

Raise the HPF until the unwanted lows begin to disappear, then back it off if the source starts losing the body it needs. Enhanced-AVL-Audio-Mixing-Cheat…

Again, listen instead of relying on a magic number.

Compression Doesn’t Have to Be Complicated

Compression is another tool that sounds more intimidating than it needs to be.

At its core, a compressor helps control the difference between louder and quieter moments.

You primarily need to understand:

Threshold, ratio, attack, release, knee, and makeup gain.

For vocals, our cheat sheet gives a deliberately gentle starting point: a 2:1–3:1 ratio, 10–30 ms attack, 80–150 ms release, and roughly 3–6 dB of gain reduction on peaks.

Then bypass the compressor and compare at equal loudness.

Those aren’t presets. They’re somewhere to begin. Enhanced-AVL-Audio-Mixing-Cheat…

Build the Mix Around the Message

This may be the most important concept in the entire course.

Don’t mix every channel independently and hope they somehow fit together.

Build a mix.

For most church environments, the lead voice needs to remain understandable. Kick and bass often form the musical foundation, while guitars, keys, backing vocals, effects, and other elements fit around them.

When something isn’t clear, your first instinct shouldn’t always be:

Turn it up.

Sometimes the better solution is turning something else down or making a small EQ adjustment to create space.

Our cheat sheet summarizes it this way: bring the lead voice forward, fit the band around it, make space before adding level, and keep effects supportive. Enhanced-AVL-Audio-Mixing-Cheat…

That’s mixing.

Download the Free Audio Mixing Cheat Sheet

We created the Enhance AVL Audio Mixing Cheat Sheet as something you can print, laminate, keep at FOH, or give to every new audio volunteer.

It includes quick references for:

• Frequency ranges and common EQ problem areas
• Vocal frequency ranges
• Starting EQ areas for common instruments
• Basic console signal flow
• Gain structure and digital headroom
• Compression controls and a gentle vocal starting point
• Panning and mix-building principles

And if you’re new to mixing—or you’re responsible for training volunteers—I recommend going through the complete FOH Audio Engineer 101 course alongside it.

The cheat sheet tells you where to start.

The course teaches you why you’re doing it.

Enhance. Don’t Distract.

At the end of the day, none of these numbers are rules.

They’re starting points.

The source, the room, the PA, the song, and the people on stage are going to change.

Learn the fundamentals. Learn your console. Most importantly, learn to listen.

Because the goal isn’t to show everyone what the sound system can do.

The goal is for the technology to enhance what’s happening without becoming the distraction.
