The Worship EQ Cheat Sheet

A complete frequency reference for vocals and instruments in a house of worship setting — with visual EQ curves, a per-source diagnostic system, and the practical knowledge a volunteer or seasoned engineer needs on a Sunday morning.

01 The Frequency Spectrum, At A Glance⌄

Six bands, one room.

Every EQ decision lives somewhere on this spectrum. Learn the territory before you start moving knobs.

20 – 60 Hz

Sub Bass

Felt, not heard. Kick subs, low organ pedals. Cut on most channels.

60 – 250 Hz

Bass

Warmth, body, fundamental of bass guitar & kick. Mud lives here.

250 – 800 Hz

Low Mids

Boxiness, "honk", body of vocals & guitars. The danger zone.

800 Hz – 3 kHz

Mids

Where the human voice lives. Intelligibility and attack.

3 – 8 kHz

High Mids

Presence, articulation, consonants. Harshness if overdone.

8 – 20 kHz

Air

Sparkle, openness, cymbals. The polish on top.

04 Universal Principles⌄

— I.

Cut before you boost.

Subtractive EQ is almost always cleaner. Removing what's wrong reveals what's right. If you must boost, do it with a wide Q and a light hand.

— II.

EQ in context, not in solo.

A guitar that sounds amazing alone might fight the vocal in the mix. Always make decisions with the full band playing — the room is the final filter.

— III.

The vocal is sacred.

In worship, the congregation needs to hear the words. Carve space for the lead vocal in every other channel. If something competes with the vocal, the vocal wins.

— IV.

High-pass everything that isn't bass.

Roll off the lows on vocals, guitars, keys, overheads — anything that doesn't need sub-bass content. Your low end stays clear and your subs stop working overtime.

— V.

Narrow Q to fix, wide Q to shape.

Tight bell curves (Q 4+) hunt and kill problem resonances. Wide curves (Q 0.7–1.2) gently sculpt tone. Use the right tool for the job.

— VI.

Trust the room, then trust your ears.

Every sanctuary has its own acoustic signature — bare walls ring, carpet absorbs, low ceilings build mud. Your EQ must adapt. The "right" setting is the one that sounds right here.

05 Mix-Wide Diagnosis⌄

If you hear…

It's likely…

Try this

Muddy, congested mix

Build-up around 200–400 Hz across many channels

CUT 250 Hz, narrow Q, –3 to –6 dB on guitars/keys

Boxy, "cardboard" vocal

Proximity effect & lower-mid build-up

CUT 300–500 Hz, –3 dB · HPF at 100 Hz

Harsh, ear-piercing top end

Resonance around 2–4 kHz

CUT 2.5–3.5 kHz, narrow Q, –3 dB · de-ess vocals

Vocals lost in the band

Guitars and keys masking 1–3 kHz vocal range

CUT 1.5–2 kHz on competing instruments, –2 dB

Thin, lifeless mix

Over-cutting low-mids; no body

Gentle BOOST 200–300 Hz, wide Q, +1 to +2 dB

Feedback ringing

Specific room resonance hot in monitors

Narrow Q (8+), CUT –6 dB · sweep to find & notch

Dull, flat acoustic guitar

Lacking sparkle in the highs

BOOST 8–10 kHz, wide Q, +2 dB · CUT 200 Hz

Sibilant, hissy vocal

Excess energy at 5–8 kHz on consonants

De-esser at 6 kHz, –4 to –6 dB · or notch at 6 kHz

Kick disappears in mix

Bass guitar & kick fighting at same frequencies

BOOST kick at 4 kHz (click) · CUT bass at 60–80 Hz
